Analysis, synthesis, critique

Literature reviews build a story. You are telling the story about what you are researching. Therefore, a literature review is a handy way to show that you know what you are talking about. To do this, here are a few important skills you will need.

Skill #1: Analysis

Analysis means that you have carefully read a wide range of the literature on your topic and have understood the main themes, and identified how the literature relates to your own topic. Carefully read and analyze the articles you find in your search, and take notes. Notice the main point of the article, the methodologies used, what conclusions are reached, and what the main themes are. Most bibliographic management tools have capability to keep notes on each article you find, tag them with keywords, and organize into groups.

Skill #2: Synthesis

After you’ve read the literature, you will start to see some themes and categories emerge, some research trends to emerge, to see where scholars agree or disagree, and how works in your chosen field or discipline are related. One way to keep track of this is by using a Synthesis Matrix .

Skill #3: Critique

As you are writing your literature review, you will want to apply a critical eye to the literature you have evaluated and synthesized. Consider the strong arguments you will make contrasted with the potential gaps in previous research. The words that you choose to report your critiques of the literature will be non-neutral. For instance, using a word like “attempted” suggests that a researcher tried something but was not successful. For example: 

There were some attempts by Smith (2012) and Jones (2013) to integrate a new methodology in this process.

On the other hand, using a word like “proved” or a phrase like “produced results” evokes a more positive argument. For example:

The new methodologies employed by Blake (2014) produced results that provided further evidence of X.

In your critique, you can point out where you believe there is room for more coverage in a topic, or further exploration in in a sub-topic.

Writing a Literature Review

Welcome to the Purdue OWL

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Prevent plagiarism, run a free check.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarise yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

What is a literature review?

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

What is the purpose of literature review?

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2  

1. Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge. 

2. Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field.

3. Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research. 

4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 

5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 

6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

a. Habitat Loss and Species Extinction:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

b. Range Shifts and Phenological Changes:

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

c. Ocean Acidification and Coral Reefs:

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

d. Adaptive Strategies and Conservation Efforts:

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

Conducting a literature review

Conducting a literature review is an essential step in research that involves reviewing and analyzing existing literature on a specific topic. It’s important to know how to do a literature review effectively, so here are the steps to follow: 1  

Choose a Topic and Define the Research Question:

• Select a topic that is relevant to your field of study. 
• Clearly define your research question or objective. Determine what specific aspect of the topic do you want to explore? 

Decide on the Scope of Your Review:

• Determine the timeframe for your literature review. Are you focusing on recent developments, or do you want a historical overview? 
• Consider the geographical scope. Is your review global, or are you focusing on a specific region? 
• Define the inclusion and exclusion criteria. What types of sources will you include? Are there specific types of studies or publications you will exclude? 

Select Databases for Searches:

• Identify relevant databases for your field. Examples include PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar. 
• Consider searching in library catalogs, institutional repositories, and specialized databases related to your topic. 

Conduct Searches and Keep Track:

• Develop a systematic search strategy using keywords, Boolean operators (AND, OR, NOT), and other search techniques. 
• Record and document your search strategy for transparency and replicability. 
• Keep track of the articles, including publication details, abstracts, and links. Use citation management tools like EndNote, Zotero, or Mendeley to organize your references. 

Review the Literature:

• Evaluate the relevance and quality of each source. Consider the methodology, sample size, and results of studies. 
• Organize the literature by themes or key concepts. Identify patterns, trends, and gaps in the existing research. 
• Summarize key findings and arguments from each source. Compare and contrast different perspectives. 
• Identify areas where there is a consensus in the literature and where there are conflicting opinions. 
• Provide critical analysis and synthesis of the literature. What are the strengths and weaknesses of existing research? 

Organize and Write Your Literature Review:

• Literature review outline should be based on themes, chronological order, or methodological approaches. 
• Write a clear and coherent narrative that synthesizes the information gathered. 
• Use proper citations for each source and ensure consistency in your citation style (APA, MLA, Chicago, etc.). 
• Conclude your literature review by summarizing key findings, identifying gaps, and suggesting areas for future research.

Frequently asked questions

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic.

Critiques evaluate and analyze a wide variety of things (texts, images, performances, etc.) based on reasons or criteria. Sometimes, people equate the notion of “critique” to “criticism,” which usually suggests a negative interpretation. These terms are easy to confuse, but I want to be clear that critique and criticize don’t mean the same thing. A negative critique might be said to be “criticism” in the way we often understand the term “to criticize,” but critiques can be positive too.

We’re all familiar with one of the most basic forms of critique: reviews (film reviews, music reviews, art reviews, book reviews, etc.). Critiques in the form of reviews tend to have a fairly simple and particular point: whether or not something is “good” or “bad.”

Academic critiques are similar to the reviews we see in popular sources in that critique writers are trying to make a particular point about whatever it is that they are critiquing. But there are some differences between the sorts of critiques we read in academic sources versus the ones we read in popular sources.

• The subjects of academic critiques tend to be other academic writings and they frequently appear in scholarly journals.
• Academic critiques frequently go further in making an argument beyond a simple assessment of the quality of a particular book, film, performance, or work of art. Academic critique writers will often compare and discuss several works that are similar to each other to make some larger point. In other words, instead of simply commenting on whether something was good or bad, academic critiques tend to explore issues and ideas in ways that are more complicated than merely “good” or “bad.”

The main focus of this chapter is the value of writing critiques as a part of the research writing process. Critiquing writing is important because in order to write a good critique you need to critically read : that is, you need to closely read and understand whatever it is you are critiquing, you need to apply appropriate criteria in order evaluate it, you need to summarize it, and to ultimately make some sort of point about the text you are critiquing.

These skills-- critically and closely reading, summarizing, creating and applying criteria, and then making an evaluation-- are key to The Process of Research Writing, and they should help you as you work through the process of research writing.

In this chapter, I’ve provided a “step-by-step” process for making a critique. I would encourage you to quickly read or skim through this chapter first, and then go back and work through the steps and exercises describe.

Selecting the right text to critique

The first step in writing a critique is selecting a text to critique. For the purposes of this writing exercise, you should check with your teacher for guidelines on what text to pick. If you are doing an annotated bibliography as part of your research project (see chapter 6, “The Annotated Bibliography Exercise”), then you are might find more materials that will work well for this project as you continuously research.

Short and simple newspaper articles, while useful as part of the research process, can be difficult to critique since they don’t have the sort of detail that easily allows for a critical reading. On the other hand, critiquing an entire book is probably a more ambitious task than you are likely to have time or energy for with this exercise. Instead, consider critiquing one of the more fully developed texts you’ve come across in your research: an in-depth examination from a news magazine, a chapter from a scholarly book, a report on a research study or experiment, or an analysis published in an academic journal. These more complex essays usually present more opportunities for issues to critique.

Depending on your teacher’s assignment, the “text” you critique might include something that isn’t in writing: a movie, a music CD, a multimedia presentation, a computer game, a painting, etc. As is the case with more traditional writings, you want to select a text that has enough substance to it so that it stands up to a critical reading.

Exercise 7.1

Pick out at least three different possibilities for texts that you could critique for this exercise. If you’ve already started work on your research and an annotated bibliography for your research topic, you should consider those pieces of research as possibilities. Working alone or in small groups, consider the potential of each text. Here are some questions to think about:

• Does the text provide in-depth information? How long is it? Does it include a “works cited” or bibliography section?
• What is the source of the text? Does it come from an academic, professional, or scholarly publication?
• Does the text advocate a particular position? What is it, and do you agree or disagree with the text?

Definition of Critique

Critique is a literary technique that means to critically evaluate a piece of literary work, or a political or philosophical theory in detail. A critique could be a critical essay , an article evaluating a literary piece, or a review. It may be just like a summary that identifies the central issue, raises questions, takes notice of theoretical and experimental approaches, and reviews the significance of the results. Apart from that, its purpose is to highlight both the shortcomings as well as strengths of a literary piece or a work of art. Moreover, critical evaluation or assessment requires sufficient knowledge about the subject matter.

Examples of Critique in Literature

Example #1: the guardian (by philip hope-wallace).

In The Guardian , critic Philip Hope-Wallace has portrayed Beckett’s play , Waiting for Godot, as “inexplicit and deliberately fatuous.” He also claimed this play to have “bored some people acutely. [while] Others found it a witty and poetic conundrum .” Godot would possibly be a God, and the dresses of tramps are like Chaplinesque zanies in a circus. Both speak futile cross talks like music hall exchanges. This play bored audience acutely, while others consider it as a poetic and witty conundrum. Finally, he calls the play a dramatic vacuum. It is without any plot , climax , denouement , beginning, middle and end.

Example #2: The Washington Post (By The Washington Post)

A famous writer, Jonathan Yardley, gives a complete analysis of F. Scott Fitzgerald’s popular novel , The Great Gatsby in The Washington Post . He calls the novel an enormous achievement in Fitzgerald’s career. It is his masterwork and seems that no other American novel could ever come close to its literary artistry.

This novel is very popular, and its every passage is famous, thus there is no need to retrace its details and familiar background. Fitzgerald has written it with unusual subtlety and sustained that tone in the entire novel. In the end, he says that this novel is “the most beautiful, compelling and  true  in all of American literature.” Then he says, “If from all of our country’s books I could have only one, The Great Gatsby , would be it.”

Example #3: Hamlet: Poem Unlimited (By Harold Bloom)

In his book, Hamlet : Poem Unlimited , Harold Bloom declares William Shakespeare ’s Hamlet as “unlimited,” coming “of no genre ,” because its greatness “… competes only with the world’s scriptures.” This amazing significance cannot emerge from a work, which is about tendentious and politicized things.

Bloom abandons the idea that Prince Hamlet ’s double shock of his father’s death and his mother’s second marriage has brought a drastic change in Hamlet. The truth, however, is that “Something in Hamlet dies before the play opens.” In fact, the theme or central idea of this play is “Hamlet’s consciousness of his own consciousness, unlimited yet at war with itself.” Thus, the play is about awakening of self-awareness, and Hamlet fights with “his desire to come to an end of playacting.”

Example #4: The Daily Telegraph (By Victoria Lambert)

Victoria Lambert, in The Daily Telegraph, writes her critical reviews on Jane Austen ’s novel, Pride and Prejudice . She describes the novel as surprisingly comforting as much as iconoclastic. It is a great story that challenges the people’s perceptions, and also draws a line through their thoughts and female history.

Certainly, there is an enjoyment of the Georgian grace, a world where we can solve problems by a ball invitation, a new gown, and scrumptious gossip. The social life at Hampshire Vicarage, its complex social mores, obsessions with money and class, its picnics and parities, draw the readers – especially females – to a point of obsession. The critics appreciate Austen’s overall depiction of the way money rules a society. She also admits Austen’s ability to describe the human heart in detail, setting her literary pulse racing.

Function of Critique

Critiques vary widely, ranging from giving reviews of books, as these reviews might determine whether a book is going to be popular or not, to rhetorical analysis of articles and pieces of artwork. Its advantage is that, despite negative criticism and reviews, many books win commercial success. Sometimes a critic serves as a scholarly detective, authenticating unknown books and unearthing master pieces. Thus, obscure scholarly skills could work as a most basic criticism, bringing literary pieces to public attention.

Besides, a critique may antagonize the author. Many authors do not feel that literature needs investigators, and advocates are not happy when they hear that their works are imitative, incomplete, or have unintended meanings. However, most critiques are useful, as they help improve the works of authors.

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

• A research paper assigned in a course
• A thesis or dissertation
• A grant proposal
• An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

• Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

• Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

• Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts .  Journal of Advanced Nursing , 53 (3), 311-318.

• Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis:  10.1177/05390184221113735

A literature critique, sometimes called a literary analysis or a literary critical analysis, is an examination of a piece of literature. The scope of a critique of literature may be to examine a single aspect of the work, or the work in its entirety, and involves breaking the literary piece apart into its separate components and evaluating how they fit together to accomplish the piece's purpose. Literary critiques are commonly executed by students, scholars, and literary critics, but anyone can learn how to critique literature!

Conducting a Basic Critique for Beginners

• For example, for a T-chart, list the names of the characters in one column and their actions in another as you read. After reading, you can add a column with why you think they did each action.

• This is similar to artwork. Instead of looking at a painting to figure out what the artist was communicating, just look at what is literally present in the painting. For example, what items are present in Van Gogh’s ‘’Starry Night’’? Don’t think about what he is trying to say in this painting; think about the stars, the swirling night sky, and the houses below.

• For example, ask yourself, why does the witch turn the prince into a beast in Beauty and the Beast? What does this action suggest about human nature?
• Also think about what lesson the reader can learn from the characters. What does the Beast teach us?

• The format for a thesis may look something like this: _______ is true because __________, ____________, and ___________. [3] X Research source The first blank is your opinion. For example, The Beast teaches us that we should be hospitable to everyone.
• The rest of the blanks tell why your opinion is true: The Beast teaches us that we should be hospitable to everyone because he learns from his mistake, becomes a compassionate person through his time as a beast, and regrets that he was ever rude to the witch.
• However, keep in mind that there are many different ways to form a thesis. What is most important if to make sure that your thesis includes a claim and a summary of the reasons for your claim. For example, you might phrase your thesis as “Because the Beast suffers for his actions, Beauty and the Beast argues that we should be hospitable to everyone and this theme carries through the story.”

• You can summarize these events, or use direct quotes from the book, but both need to have a page number. This prevents plagiarism.
• For example, you might use a quote that shows how the Beast is inhospitable as one of your first examples. Then, you might use other examples from the text to show the continuation of this theme.
• You do not have to use direct quotes all of the time. You can also paraphrase a passage by putting it into your own words, or summarize longer passages by describing the events in a less detailed way in your own words. No matter if you are quoting, paraphrasing, or summarizing, make sure that you include a page number for your evidence.

• Fill in the outline with topic sentences and events from the literature that support each topic sentence.

• Close the essay with a conclusion paragraph, where you summarize the essay in just a few sentences.

Applying Advanced Critical Techniques

• You should read with a pen and paper handy, as well as with a dictionary. Write down the main ideas in the margins and look up words as you go.
• Ask “how,” “why,” and “so what” questions to help you read critically.

• Evaluate elements of the work as you go, such as plot, themes, instances of character development, setting, symbols, conflicts, and point of view. [6] X Research source Think about how these elements interact to form the main theme.

• making a list,
• mapping out a web, and
• freewriting.
• For example, while reading Pride and Prejudice, you might feel that Mr. Darcy’s character needed more development than Jane Austen gave him, or you might prefer Jane’s character to Lizzy’s and feel that she would have made a better heroine (for example, Jane shares a name with the author, giving you grounds to explore the argument that Austen might have actually preferred her). Make a list, web, or freewrite out of ideas like these.

• The thesis should present your opinion in an arguable manner accompanied by a solid reason why your opinion is true.
• The formula for a basic thesis statement might look like this: _______ is true because of __________, ____________, and ___________. [8] X Research source

• You can also take advantage of an outline to form key sentences like the hook (first line of the intro paragraph), topic and transition sentences for each body paragraph, and your conclusion.

• Look at your notes and identify any patterns you see in the text that support your thesis statement, such as how no one is ever sure what Mr. Darcy is doing until after the fact, contributing to a lack of character development in Pride and Prejudice (if you were trying to prove the validity of an argument that Mr. Darcy is not developed enough, for example).
• You must include a page number or authorial attribution anytime that you: talk about a specific event; paraphrase a quote; paraphrase a passage; or use any direct quote. You usually insert a page number in parentheses after the sentence.

• You should also address any criticism that does not agree with your thesis, as refuting the counterargument also builds your credibility.

• If you created your outline on a word processor, then you can simply fill in the outline with additional information.
• You can also treat the outline as a roadmap. Consult it as you draft your paper to make sure that you are including all of the points and examples that you have identified.

• MLA is more common for literary-based essays, but you should ask your instructor if you are not sure.

• For example, after offering a quote, you might explain what the quote means or demonstrates as well as how it supports your thesis. Do not simply paraphrase or summarize the quotes after you offer them. Summary does not show critical thinking. Instead, try to explain the significance of each quote or example to your readers.
• Try to create quote sandwiches. A quote sandwich is simply how you position a quote in an essay. You should have a sentence introducing the quote and its author, then have the quote itself, followed by one or more sentences analyzing the quote right after it.
• Make sure you include a references/works cited list with all sources you quote from or paraphrase in the essay. This prevents plagiarism.

Evaluating Literature as You Read

• Questioning the title helps in determining the main theme and contributes to a more accurate critique.

• Setting—description of the surroundings.
• Plot—events of the text.
• Characters—the motivations and depth of each character, such as how much they change or don’t change as a result of the events. Characters can be people, objects, even ideas (especially in poetry).
• Conflict—the opposition that the main character encounters and its climax and resolution.
• Themes—what the narrator observes about human nature.
• Point of view—the way that a character thinks, whether it is curious, condescending, etc. Can also be the perspective the text is told, whether in first person, third person, etc.
• Tone—the way the text feels, whether sad, happy, angry, apathetic, etc.
• Symbols—objects, people, or places that repeat consistently throughout the story and seem to represent another abstract idea.

• You may want to write down your interpretation of the work at this point, as it is an excellent springboard into a thesis statement, if you end up needing to write a paper about this text.
• You can review outside sources such as peer reviewed articles and books to verify that your interpretation is accurate or needs work.

About This Article

To critique literature, start by carefully reading the text and then coming up with an opinion, like whether or not you think the author did a good job getting their main point across. Then, find evidence in the text to support your opinion, including things like quotes, events in the story, and actions the characters made. Once you have your argument and evidence support it, write your critique so that each paragraph addresses a different piece of evidence.

Associated Data

To frame their work, biology education researchers need to consider the role of literature reviews, theoretical frameworks, and conceptual frameworks as critical elements of the research and writing process. However, these elements can be confusing for scholars new to education research. This Research Methods article is designed to provide an overview of each of these elements and delineate the purpose of each in the educational research process. We describe what biology education researchers should consider as they conduct literature reviews, identify theoretical frameworks, and construct conceptual frameworks. Clarifying these different components of educational research studies can be helpful to new biology education researchers and the biology education research community at large in situating their work in the broader scholarly literature.

INTRODUCTION

Discipline-based education research (DBER) involves the purposeful and situated study of teaching and learning in specific disciplinary areas ( Singer et al. , 2012 ). Studies in DBER are guided by research questions that reflect disciplines’ priorities and worldviews. Researchers can use quantitative data, qualitative data, or both to answer these research questions through a variety of methodological traditions. Across all methodologies, there are different methods associated with planning and conducting educational research studies that include the use of surveys, interviews, observations, artifacts, or instruments. Ensuring the coherence of these elements to the discipline’s perspective also involves situating the work in the broader scholarly literature. The tools for doing this include literature reviews, theoretical frameworks, and conceptual frameworks. However, the purpose and function of each of these elements is often confusing to new education researchers. The goal of this article is to introduce new biology education researchers to these three important elements important in DBER scholarship and the broader educational literature.

The first element we discuss is a review of research (literature reviews), which highlights the need for a specific research question, study problem, or topic of investigation. Literature reviews situate the relevance of the study within a topic and a field. The process may seem familiar to science researchers entering DBER fields, but new researchers may still struggle in conducting the review. Booth et al. (2016b) highlight some of the challenges novice education researchers face when conducting a review of literature. They point out that novice researchers struggle in deciding how to focus the review, determining the scope of articles needed in the review, and knowing how to be critical of the articles in the review. Overcoming these challenges (and others) can help novice researchers construct a sound literature review that can inform the design of the study and help ensure the work makes a contribution to the field.

The second and third highlighted elements are theoretical and conceptual frameworks. These guide biology education research (BER) studies, and may be less familiar to science researchers. These elements are important in shaping the construction of new knowledge. Theoretical frameworks offer a way to explain and interpret the studied phenomenon, while conceptual frameworks clarify assumptions about the studied phenomenon. Despite the importance of these constructs in educational research, biology educational researchers have noted the limited use of theoretical or conceptual frameworks in published work ( DeHaan, 2011 ; Dirks, 2011 ; Lo et al. , 2019 ). In reviewing articles published in CBE—Life Sciences Education ( LSE ) between 2015 and 2019, we found that fewer than 25% of the research articles had a theoretical or conceptual framework (see the Supplemental Information), and at times there was an inconsistent use of theoretical and conceptual frameworks. Clearly, these frameworks are challenging for published biology education researchers, which suggests the importance of providing some initial guidance to new biology education researchers.

Fortunately, educational researchers have increased their explicit use of these frameworks over time, and this is influencing educational research in science, technology, engineering, and mathematics (STEM) fields. For instance, a quick search for theoretical or conceptual frameworks in the abstracts of articles in Educational Research Complete (a common database for educational research) in STEM fields demonstrates a dramatic change over the last 20 years: from only 778 articles published between 2000 and 2010 to 5703 articles published between 2010 and 2020, a more than sevenfold increase. Greater recognition of the importance of these frameworks is contributing to DBER authors being more explicit about such frameworks in their studies.

Collectively, literature reviews, theoretical frameworks, and conceptual frameworks work to guide methodological decisions and the elucidation of important findings. Each offers a different perspective on the problem of study and is an essential element in all forms of educational research. As new researchers seek to learn about these elements, they will find different resources, a variety of perspectives, and many suggestions about the construction and use of these elements. The wide range of available information can overwhelm the new researcher who just wants to learn the distinction between these elements or how to craft them adequately.

Our goal in writing this paper is not to offer specific advice about how to write these sections in scholarly work. Instead, we wanted to introduce these elements to those who are new to BER and who are interested in better distinguishing one from the other. In this paper, we share the purpose of each element in BER scholarship, along with important points on its construction. We also provide references for additional resources that may be beneficial to better understanding each element. Table 1 summarizes the key distinctions among these elements.

Comparison of literature reviews, theoretical frameworks, and conceptual reviews

This article is written for the new biology education researcher who is just learning about these different elements or for scientists looking to become more involved in BER. It is a result of our own work as science education and biology education researchers, whether as graduate students and postdoctoral scholars or newly hired and established faculty members. This is the article we wish had been available as we started to learn about these elements or discussed them with new educational researchers in biology.

LITERATURE REVIEWS

Purpose of a literature review.

A literature review is foundational to any research study in education or science. In education, a well-conceptualized and well-executed review provides a summary of the research that has already been done on a specific topic and identifies questions that remain to be answered, thus illustrating the current research project’s potential contribution to the field and the reasoning behind the methodological approach selected for the study ( Maxwell, 2012 ). BER is an evolving disciplinary area that is redefining areas of conceptual emphasis as well as orientations toward teaching and learning (e.g., Labov et al. , 2010 ; American Association for the Advancement of Science, 2011 ; Nehm, 2019 ). As a result, building comprehensive, critical, purposeful, and concise literature reviews can be a challenge for new biology education researchers.

Building Literature Reviews

There are different ways to approach and construct a literature review. Booth et al. (2016a) provide an overview that includes, for example, scoping reviews, which are focused only on notable studies and use a basic method of analysis, and integrative reviews, which are the result of exhaustive literature searches across different genres. Underlying each of these different review processes are attention to the s earch process, a ppraisa l of articles, s ynthesis of the literature, and a nalysis: SALSA ( Booth et al. , 2016a ). This useful acronym can help the researcher focus on the process while building a specific type of review.

However, new educational researchers often have questions about literature reviews that are foundational to SALSA or other approaches. Common questions concern determining which literature pertains to the topic of study or the role of the literature review in the design of the study. This section addresses such questions broadly while providing general guidance for writing a narrative literature review that evaluates the most pertinent studies.

The literature review process should begin before the research is conducted. As Boote and Beile (2005 , p. 3) suggested, researchers should be “scholars before researchers.” They point out that having a good working knowledge of the proposed topic helps illuminate avenues of study. Some subject areas have a deep body of work to read and reflect upon, providing a strong foundation for developing the research question(s). For instance, the teaching and learning of evolution is an area of long-standing interest in the BER community, generating many studies (e.g., Perry et al. , 2008 ; Barnes and Brownell, 2016 ) and reviews of research (e.g., Sickel and Friedrichsen, 2013 ; Ziadie and Andrews, 2018 ). Emerging areas of BER include the affective domain, issues of transfer, and metacognition ( Singer et al. , 2012 ). Many studies in these areas are transdisciplinary and not always specific to biology education (e.g., Rodrigo-Peiris et al. , 2018 ; Kolpikova et al. , 2019 ). These newer areas may require reading outside BER; fortunately, summaries of some of these topics can be found in the Current Insights section of the LSE website.

In focusing on a specific problem within a broader research strand, a new researcher will likely need to examine research outside BER. Depending upon the area of study, the expanded reading list might involve a mix of BER, DBER, and educational research studies. Determining the scope of the reading is not always straightforward. A simple way to focus one’s reading is to create a “summary phrase” or “research nugget,” which is a very brief descriptive statement about the study. It should focus on the essence of the study, for example, “first-year nonmajor students’ understanding of evolution,” “metacognitive prompts to enhance learning during biochemistry,” or “instructors’ inquiry-based instructional practices after professional development programming.” This type of phrase should help a new researcher identify two or more areas to review that pertain to the study. Focusing on recent research in the last 5 years is a good first step. Additional studies can be identified by reading relevant works referenced in those articles. It is also important to read seminal studies that are more than 5 years old. Reading a range of studies should give the researcher the necessary command of the subject in order to suggest a research question.

Given that the research question(s) arise from the literature review, the review should also substantiate the selected methodological approach. The review and research question(s) guide the researcher in determining how to collect and analyze data. Often the methodological approach used in a study is selected to contribute knowledge that expands upon what has been published previously about the topic (see Institute of Education Sciences and National Science Foundation, 2013 ). An emerging topic of study may need an exploratory approach that allows for a description of the phenomenon and development of a potential theory. This could, but not necessarily, require a methodological approach that uses interviews, observations, surveys, or other instruments. An extensively studied topic may call for the additional understanding of specific factors or variables; this type of study would be well suited to a verification or a causal research design. These could entail a methodological approach that uses valid and reliable instruments, observations, or interviews to determine an effect in the studied event. In either of these examples, the researcher(s) may use a qualitative, quantitative, or mixed methods methodological approach.

Even with a good research question, there is still more reading to be done. The complexity and focus of the research question dictates the depth and breadth of the literature to be examined. Questions that connect multiple topics can require broad literature reviews. For instance, a study that explores the impact of a biology faculty learning community on the inquiry instruction of faculty could have the following review areas: learning communities among biology faculty, inquiry instruction among biology faculty, and inquiry instruction among biology faculty as a result of professional learning. Biology education researchers need to consider whether their literature review requires studies from different disciplines within or outside DBER. For the example given, it would be fruitful to look at research focused on learning communities with faculty in STEM fields or in general education fields that result in instructional change. It is important not to be too narrow or too broad when reading. When the conclusions of articles start to sound similar or no new insights are gained, the researcher likely has a good foundation for a literature review. This level of reading should allow the researcher to demonstrate a mastery in understanding the researched topic, explain the suitability of the proposed research approach, and point to the need for the refined research question(s).

The literature review should include the researcher’s evaluation and critique of the selected studies. A researcher may have a large collection of studies, but not all of the studies will follow standards important in the reporting of empirical work in the social sciences. The American Educational Research Association ( Duran et al. , 2006 ), for example, offers a general discussion about standards for such work: an adequate review of research informing the study, the existence of sound and appropriate data collection and analysis methods, and appropriate conclusions that do not overstep or underexplore the analyzed data. The Institute of Education Sciences and National Science Foundation (2013) also offer Common Guidelines for Education Research and Development that can be used to evaluate collected studies.

Because not all journals adhere to such standards, it is important that a researcher review each study to determine the quality of published research, per the guidelines suggested earlier. In some instances, the research may be fatally flawed. Examples of such flaws include data that do not pertain to the question, a lack of discussion about the data collection, poorly constructed instruments, or an inadequate analysis. These types of errors result in studies that are incomplete, error-laden, or inaccurate and should be excluded from the review. Most studies have limitations, and the author(s) often make them explicit. For instance, there may be an instructor effect, recognized bias in the analysis, or issues with the sample population. Limitations are usually addressed by the research team in some way to ensure a sound and acceptable research process. Occasionally, the limitations associated with the study can be significant and not addressed adequately, which leaves a consequential decision in the hands of the researcher. Providing critiques of studies in the literature review process gives the reader confidence that the researcher has carefully examined relevant work in preparation for the study and, ultimately, the manuscript.

A solid literature review clearly anchors the proposed study in the field and connects the research question(s), the methodological approach, and the discussion. Reviewing extant research leads to research questions that will contribute to what is known in the field. By summarizing what is known, the literature review points to what needs to be known, which in turn guides decisions about methodology. Finally, notable findings of the new study are discussed in reference to those described in the literature review.

Within published BER studies, literature reviews can be placed in different locations in an article. When included in the introductory section of the study, the first few paragraphs of the manuscript set the stage, with the literature review following the opening paragraphs. Cooper et al. (2019) illustrate this approach in their study of course-based undergraduate research experiences (CUREs). An introduction discussing the potential of CURES is followed by an analysis of the existing literature relevant to the design of CUREs that allows for novel student discoveries. Within this review, the authors point out contradictory findings among research on novel student discoveries. This clarifies the need for their study, which is described and highlighted through specific research aims.

A literature reviews can also make up a separate section in a paper. For example, the introduction to Todd et al. (2019) illustrates the need for their research topic by highlighting the potential of learning progressions (LPs) and suggesting that LPs may help mitigate learning loss in genetics. At the end of the introduction, the authors state their specific research questions. The review of literature following this opening section comprises two subsections. One focuses on learning loss in general and examines a variety of studies and meta-analyses from the disciplines of medical education, mathematics, and reading. The second section focuses specifically on LPs in genetics and highlights student learning in the midst of LPs. These separate reviews provide insights into the stated research question.

Suggestions and Advice

A well-conceptualized, comprehensive, and critical literature review reveals the understanding of the topic that the researcher brings to the study. Literature reviews should not be so big that there is no clear area of focus; nor should they be so narrow that no real research question arises. The task for a researcher is to craft an efficient literature review that offers a critical analysis of published work, articulates the need for the study, guides the methodological approach to the topic of study, and provides an adequate foundation for the discussion of the findings.

In our own writing of literature reviews, there are often many drafts. An early draft may seem well suited to the study because the need for and approach to the study are well described. However, as the results of the study are analyzed and findings begin to emerge, the existing literature review may be inadequate and need revision. The need for an expanded discussion about the research area can result in the inclusion of new studies that support the explanation of a potential finding. The literature review may also prove to be too broad. Refocusing on a specific area allows for more contemplation of a finding.

It should be noted that there are different types of literature reviews, and many books and articles have been written about the different ways to embark on these types of reviews. Among these different resources, the following may be helpful in considering how to refine the review process for scholarly journals:

This book addresses different types of literature reviews and offers important suggestions pertaining to defining the scope of the literature review and assessing extant studies.

While this book is not specifically about literature reviews, it offers suggestions about making the case for your study.

This book offers guidance on writing different types of literature reviews. For the novice researcher, there are useful suggestions for creating coherent literature reviews.

THEORETICAL FRAMEWORKS

Purpose of theoretical frameworks.

As new education researchers may be less familiar with theoretical frameworks than with literature reviews, this discussion begins with an analogy. Envision a biologist, chemist, and physicist examining together the dramatic effect of a fog tsunami over the ocean. A biologist gazing at this phenomenon may be concerned with the effect of fog on various species. A chemist may be interested in the chemical composition of the fog as water vapor condenses around bits of salt. A physicist may be focused on the refraction of light to make fog appear to be “sitting” above the ocean. While observing the same “objective event,” the scientists are operating under different theoretical frameworks that provide a particular perspective or “lens” for the interpretation of the phenomenon. Each of these scientists brings specialized knowledge, experiences, and values to this phenomenon, and these influence the interpretation of the phenomenon. The scientists’ theoretical frameworks influence how they design and carry out their studies and interpret their data.

Within an educational study, a theoretical framework helps to explain a phenomenon through a particular lens and challenges and extends existing knowledge within the limitations of that lens. Theoretical frameworks are explicitly stated by an educational researcher in the paper’s framework, theory, or relevant literature section. The framework shapes the types of questions asked, guides the method by which data are collected and analyzed, and informs the discussion of the results of the study. It also reveals the researcher’s subjectivities, for example, values, social experience, and viewpoint ( Allen, 2017 ). It is essential that a novice researcher learn to explicitly state a theoretical framework, because all research questions are being asked from the researcher’s implicit or explicit assumptions of a phenomenon of interest ( Schwandt, 2000 ).

Selecting Theoretical Frameworks

Theoretical frameworks are one of the most contemplated elements in our work in educational research. In this section, we share three important considerations for new scholars selecting a theoretical framework.

The first step in identifying a theoretical framework involves reflecting on the phenomenon within the study and the assumptions aligned with the phenomenon. The phenomenon involves the studied event. There are many possibilities, for example, student learning, instructional approach, or group organization. A researcher holds assumptions about how the phenomenon will be effected, influenced, changed, or portrayed. It is ultimately the researcher’s assumption(s) about the phenomenon that aligns with a theoretical framework. An example can help illustrate how a researcher’s reflection on the phenomenon and acknowledgment of assumptions can result in the identification of a theoretical framework.

In our example, a biology education researcher may be interested in exploring how students’ learning of difficult biological concepts can be supported by the interactions of group members. The phenomenon of interest is the interactions among the peers, and the researcher assumes that more knowledgeable students are important in supporting the learning of the group. As a result, the researcher may draw on Vygotsky’s (1978) sociocultural theory of learning and development that is focused on the phenomenon of student learning in a social setting. This theory posits the critical nature of interactions among students and between students and teachers in the process of building knowledge. A researcher drawing upon this framework holds the assumption that learning is a dynamic social process involving questions and explanations among students in the classroom and that more knowledgeable peers play an important part in the process of building conceptual knowledge.

It is important to state at this point that there are many different theoretical frameworks. Some frameworks focus on learning and knowing, while other theoretical frameworks focus on equity, empowerment, or discourse. Some frameworks are well articulated, and others are still being refined. For a new researcher, it can be challenging to find a theoretical framework. Two of the best ways to look for theoretical frameworks is through published works that highlight different frameworks.

When a theoretical framework is selected, it should clearly connect to all parts of the study. The framework should augment the study by adding a perspective that provides greater insights into the phenomenon. It should clearly align with the studies described in the literature review. For instance, a framework focused on learning would correspond to research that reported different learning outcomes for similar studies. The methods for data collection and analysis should also correspond to the framework. For instance, a study about instructional interventions could use a theoretical framework concerned with learning and could collect data about the effect of the intervention on what is learned. When the data are analyzed, the theoretical framework should provide added meaning to the findings, and the findings should align with the theoretical framework.

A study by Jensen and Lawson (2011) provides an example of how a theoretical framework connects different parts of the study. They compared undergraduate biology students in heterogeneous and homogeneous groups over the course of a semester. Jensen and Lawson (2011) assumed that learning involved collaboration and more knowledgeable peers, which made Vygotsky’s (1978) theory a good fit for their study. They predicted that students in heterogeneous groups would experience greater improvement in their reasoning abilities and science achievements with much of the learning guided by the more knowledgeable peers.

In the enactment of the study, they collected data about the instruction in traditional and inquiry-oriented classes, while the students worked in homogeneous or heterogeneous groups. To determine the effect of working in groups, the authors also measured students’ reasoning abilities and achievement. Each data-collection and analysis decision connected to understanding the influence of collaborative work.

Their findings highlighted aspects of Vygotsky’s (1978) theory of learning. One finding, for instance, posited that inquiry instruction, as a whole, resulted in reasoning and achievement gains. This links to Vygotsky (1978) , because inquiry instruction involves interactions among group members. A more nuanced finding was that group composition had a conditional effect. Heterogeneous groups performed better with more traditional and didactic instruction, regardless of the reasoning ability of the group members. Homogeneous groups worked better during interaction-rich activities for students with low reasoning ability. The authors attributed the variation to the different types of helping behaviors of students. High-performing students provided the answers, while students with low reasoning ability had to work collectively through the material. In terms of Vygotsky (1978) , this finding provided new insights into the learning context in which productive interactions can occur for students.

Another consideration in the selection and use of a theoretical framework pertains to its orientation to the study. This can result in the theoretical framework prioritizing individuals, institutions, and/or policies ( Anfara and Mertz, 2014 ). Frameworks that connect to individuals, for instance, could contribute to understanding their actions, learning, or knowledge. Institutional frameworks, on the other hand, offer insights into how institutions, organizations, or groups can influence individuals or materials. Policy theories provide ways to understand how national or local policies can dictate an emphasis on outcomes or instructional design. These different types of frameworks highlight different aspects in an educational setting, which influences the design of the study and the collection of data. In addition, these different frameworks offer a way to make sense of the data. Aligning the data collection and analysis with the framework ensures that a study is coherent and can contribute to the field.

New understandings emerge when different theoretical frameworks are used. For instance, Ebert-May et al. (2015) prioritized the individual level within conceptual change theory (see Posner et al. , 1982 ). In this theory, an individual’s knowledge changes when it no longer fits the phenomenon. Ebert-May et al. (2015) designed a professional development program challenging biology postdoctoral scholars’ existing conceptions of teaching. The authors reported that the biology postdoctoral scholars’ teaching practices became more student-centered as they were challenged to explain their instructional decision making. According to the theory, the biology postdoctoral scholars’ dissatisfaction in their descriptions of teaching and learning initiated change in their knowledge and instruction. These results reveal how conceptual change theory can explain the learning of participants and guide the design of professional development programming.

The communities of practice (CoP) theoretical framework ( Lave, 1988 ; Wenger, 1998 ) prioritizes the institutional level , suggesting that learning occurs when individuals learn from and contribute to the communities in which they reside. Grounded in the assumption of community learning, the literature on CoP suggests that, as individuals interact regularly with the other members of their group, they learn about the rules, roles, and goals of the community ( Allee, 2000 ). A study conducted by Gehrke and Kezar (2017) used the CoP framework to understand organizational change by examining the involvement of individual faculty engaged in a cross-institutional CoP focused on changing the instructional practice of faculty at each institution. In the CoP, faculty members were involved in enhancing instructional materials within their department, which aligned with an overarching goal of instituting instruction that embraced active learning. Not surprisingly, Gehrke and Kezar (2017) revealed that faculty who perceived the community culture as important in their work cultivated institutional change. Furthermore, they found that institutional change was sustained when key leaders served as mentors and provided support for faculty, and as faculty themselves developed into leaders. This study reveals the complexity of individual roles in a COP in order to support institutional instructional change.

It is important to explicitly state the theoretical framework used in a study, but elucidating a theoretical framework can be challenging for a new educational researcher. The literature review can help to identify an applicable theoretical framework. Focal areas of the review or central terms often connect to assumptions and assertions associated with the framework that pertain to the phenomenon of interest. Another way to identify a theoretical framework is self-reflection by the researcher on personal beliefs and understandings about the nature of knowledge the researcher brings to the study ( Lysaght, 2011 ). In stating one’s beliefs and understandings related to the study (e.g., students construct their knowledge, instructional materials support learning), an orientation becomes evident that will suggest a particular theoretical framework. Theoretical frameworks are not arbitrary , but purposefully selected.

With experience, a researcher may find expanded roles for theoretical frameworks. Researchers may revise an existing framework that has limited explanatory power, or they may decide there is a need to develop a new theoretical framework. These frameworks can emerge from a current study or the need to explain a phenomenon in a new way. Researchers may also find that multiple theoretical frameworks are necessary to frame and explore a problem, as different frameworks can provide different insights into a problem.

Finally, it is important to recognize that choosing “x” theoretical framework does not necessarily mean a researcher chooses “y” methodology and so on, nor is there a clear-cut, linear process in selecting a theoretical framework for one’s study. In part, the nonlinear process of identifying a theoretical framework is what makes understanding and using theoretical frameworks challenging. For the novice scholar, contemplating and understanding theoretical frameworks is essential. Fortunately, there are articles and books that can help:

CONCEPTUAL FRAMEWORKS

Purpose of a conceptual framework.

A conceptual framework is a description of the way a researcher understands the factors and/or variables that are involved in the study and their relationships to one another. The purpose of a conceptual framework is to articulate the concepts under study using relevant literature ( Rocco and Plakhotnik, 2009 ) and to clarify the presumed relationships among those concepts ( Rocco and Plakhotnik, 2009 ; Anfara and Mertz, 2014 ). Conceptual frameworks are different from theoretical frameworks in both their breadth and grounding in established findings. Whereas a theoretical framework articulates the lens through which a researcher views the work, the conceptual framework is often more mechanistic and malleable.

Conceptual frameworks are broader, encompassing both established theories (i.e., theoretical frameworks) and the researchers’ own emergent ideas. Emergent ideas, for example, may be rooted in informal and/or unpublished observations from experience. These emergent ideas would not be considered a “theory” if they are not yet tested, supported by systematically collected evidence, and peer reviewed. However, they do still play an important role in the way researchers approach their studies. The conceptual framework allows authors to clearly describe their emergent ideas so that connections among ideas in the study and the significance of the study are apparent to readers.

Constructing Conceptual Frameworks

Including a conceptual framework in a research study is important, but researchers often opt to include either a conceptual or a theoretical framework. Either may be adequate, but both provide greater insight into the research approach. For instance, a research team plans to test a novel component of an existing theory. In their study, they describe the existing theoretical framework that informs their work and then present their own conceptual framework. Within this conceptual framework, specific topics portray emergent ideas that are related to the theory. Describing both frameworks allows readers to better understand the researchers’ assumptions, orientations, and understanding of concepts being investigated. For example, Connolly et al. (2018) included a conceptual framework that described how they applied a theoretical framework of social cognitive career theory (SCCT) to their study on teaching programs for doctoral students. In their conceptual framework, the authors described SCCT, explained how it applied to the investigation, and drew upon results from previous studies to justify the proposed connections between the theory and their emergent ideas.

In some cases, authors may be able to sufficiently describe their conceptualization of the phenomenon under study in an introduction alone, without a separate conceptual framework section. However, incomplete descriptions of how the researchers conceptualize the components of the study may limit the significance of the study by making the research less intelligible to readers. This is especially problematic when studying topics in which researchers use the same terms for different constructs or different terms for similar and overlapping constructs (e.g., inquiry, teacher beliefs, pedagogical content knowledge, or active learning). Authors must describe their conceptualization of a construct if the research is to be understandable and useful.

There are some key areas to consider regarding the inclusion of a conceptual framework in a study. To begin with, it is important to recognize that conceptual frameworks are constructed by the researchers conducting the study ( Rocco and Plakhotnik, 2009 ; Maxwell, 2012 ). This is different from theoretical frameworks that are often taken from established literature. Researchers should bring together ideas from the literature, but they may be influenced by their own experiences as a student and/or instructor, the shared experiences of others, or thought experiments as they construct a description, model, or representation of their understanding of the phenomenon under study. This is an exercise in intellectual organization and clarity that often considers what is learned, known, and experienced. The conceptual framework makes these constructs explicitly visible to readers, who may have different understandings of the phenomenon based on their prior knowledge and experience. There is no single method to go about this intellectual work.

Reeves et al. (2016) is an example of an article that proposed a conceptual framework about graduate teaching assistant professional development evaluation and research. The authors used existing literature to create a novel framework that filled a gap in current research and practice related to the training of graduate teaching assistants. This conceptual framework can guide the systematic collection of data by other researchers because the framework describes the relationships among various factors that influence teaching and learning. The Reeves et al. (2016) conceptual framework may be modified as additional data are collected and analyzed by other researchers. This is not uncommon, as conceptual frameworks can serve as catalysts for concerted research efforts that systematically explore a phenomenon (e.g., Reynolds et al. , 2012 ; Brownell and Kloser, 2015 ).

Sabel et al. (2017) used a conceptual framework in their exploration of how scaffolds, an external factor, interact with internal factors to support student learning. Their conceptual framework integrated principles from two theoretical frameworks, self-regulated learning and metacognition, to illustrate how the research team conceptualized students’ use of scaffolds in their learning ( Figure 1 ). Sabel et al. (2017) created this model using their interpretations of these two frameworks in the context of their teaching.

Conceptual framework from Sabel et al. (2017) .

A conceptual framework should describe the relationship among components of the investigation ( Anfara and Mertz, 2014 ). These relationships should guide the researcher’s methods of approaching the study ( Miles et al. , 2014 ) and inform both the data to be collected and how those data should be analyzed. Explicitly describing the connections among the ideas allows the researcher to justify the importance of the study and the rigor of the research design. Just as importantly, these frameworks help readers understand why certain components of a system were not explored in the study. This is a challenge in education research, which is rooted in complex environments with many variables that are difficult to control.

For example, Sabel et al. (2017) stated: “Scaffolds, such as enhanced answer keys and reflection questions, can help students and instructors bridge the external and internal factors and support learning” (p. 3). They connected the scaffolds in the study to the three dimensions of metacognition and the eventual transformation of existing ideas into new or revised ideas. Their framework provides a rationale for focusing on how students use two different scaffolds, and not on other factors that may influence a student’s success (self-efficacy, use of active learning, exam format, etc.).

In constructing conceptual frameworks, researchers should address needed areas of study and/or contradictions discovered in literature reviews. By attending to these areas, researchers can strengthen their arguments for the importance of a study. For instance, conceptual frameworks can address how the current study will fill gaps in the research, resolve contradictions in existing literature, or suggest a new area of study. While a literature review describes what is known and not known about the phenomenon, the conceptual framework leverages these gaps in describing the current study ( Maxwell, 2012 ). In the example of Sabel et al. (2017) , the authors indicated there was a gap in the literature regarding how scaffolds engage students in metacognition to promote learning in large classes. Their study helps fill that gap by describing how scaffolds can support students in the three dimensions of metacognition: intelligibility, plausibility, and wide applicability. In another example, Lane (2016) integrated research from science identity, the ethic of care, the sense of belonging, and an expertise model of student success to form a conceptual framework that addressed the critiques of other frameworks. In a more recent example, Sbeglia et al. (2021) illustrated how a conceptual framework influences the methodological choices and inferences in studies by educational researchers.

Sometimes researchers draw upon the conceptual frameworks of other researchers. When a researcher’s conceptual framework closely aligns with an existing framework, the discussion may be brief. For example, Ghee et al. (2016) referred to portions of SCCT as their conceptual framework to explain the significance of their work on students’ self-efficacy and career interests. Because the authors’ conceptualization of this phenomenon aligned with a previously described framework, they briefly mentioned the conceptual framework and provided additional citations that provided more detail for the readers.

Within both the BER and the broader DBER communities, conceptual frameworks have been used to describe different constructs. For example, some researchers have used the term “conceptual framework” to describe students’ conceptual understandings of a biological phenomenon. This is distinct from a researcher’s conceptual framework of the educational phenomenon under investigation, which may also need to be explicitly described in the article. Other studies have presented a research logic model or flowchart of the research design as a conceptual framework. These constructions can be quite valuable in helping readers understand the data-collection and analysis process. However, a model depicting the study design does not serve the same role as a conceptual framework. Researchers need to avoid conflating these constructs by differentiating the researchers’ conceptual framework that guides the study from the research design, when applicable.

Explicitly describing conceptual frameworks is essential in depicting the focus of the study. We have found that being explicit in a conceptual framework means using accepted terminology, referencing prior work, and clearly noting connections between terms. This description can also highlight gaps in the literature or suggest potential contributions to the field of study. A well-elucidated conceptual framework can suggest additional studies that may be warranted. This can also spur other researchers to consider how they would approach the examination of a phenomenon and could result in a revised conceptual framework.

It can be challenging to create conceptual frameworks, but they are important. Below are two resources that could be helpful in constructing and presenting conceptual frameworks in educational research:

• Maxwell, J. A. (2012). Qualitative research design: An interactive approach (3rd ed.). Los Angeles, CA: Sage. Chapter 3 in this book describes how to construct conceptual frameworks.
• Ravitch, S. M., & Riggan, M. (2016). Reason & rigor: How conceptual frameworks guide research . Los Angeles, CA: Sage. This book explains how conceptual frameworks guide the research questions, data collection, data analyses, and interpretation of results.

CONCLUDING THOUGHTS

Literature reviews, theoretical frameworks, and conceptual frameworks are all important in DBER and BER. Robust literature reviews reinforce the importance of a study. Theoretical frameworks connect the study to the base of knowledge in educational theory and specify the researcher’s assumptions. Conceptual frameworks allow researchers to explicitly describe their conceptualization of the relationships among the components of the phenomenon under study. Table 1 provides a general overview of these components in order to assist biology education researchers in thinking about these elements.

It is important to emphasize that these different elements are intertwined. When these elements are aligned and complement one another, the study is coherent, and the study findings contribute to knowledge in the field. When literature reviews, theoretical frameworks, and conceptual frameworks are disconnected from one another, the study suffers. The point of the study is lost, suggested findings are unsupported, or important conclusions are invisible to the researcher. In addition, this misalignment may be costly in terms of time and money.

Conducting a literature review, selecting a theoretical framework, and building a conceptual framework are some of the most difficult elements of a research study. It takes time to understand the relevant research, identify a theoretical framework that provides important insights into the study, and formulate a conceptual framework that organizes the finding. In the research process, there is often a constant back and forth among these elements as the study evolves. With an ongoing refinement of the review of literature, clarification of the theoretical framework, and articulation of a conceptual framework, a sound study can emerge that makes a contribution to the field. This is the goal of BER and education research.

What is a Literature Review?

A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field. 

A literature review should: 

• Provide a comprehensive and updated review of the literature;
• Explain why this review has taken place;
• Articulate a position or hypothesis;
• Acknowledge and account for conflicting and corroborating points of view

From  S age Research Methods

Purpose of a Literature Review

A literature review can be written as an introduction to a study to:

• Demonstrate how a study fills a gap in research
• Compare a study with other research that's been done

Or it can be a separate work (a research article on its own) which:

• Organizes or describes a topic
• Describes variables within a particular issue/problem

Limitations of a Literature Review

Some of the limitations of a literature review are:

• It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
• It may be too focused. Some niche studies may miss the bigger picture.
• It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
• It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

Review of Related Literature (RRL): Effects of Nutrition on Cognitive Development in Children

Ai generator, 1. introduction.

This review examines the effects of nutrition on cognitive development in children over the past decade. Proper nutrition is crucial for the physical and cognitive growth of children.

2. Theoretical Framework

Based on Nutritional Neuroscience and Developmental Psychology theories, this review explores how nutrition influences cognitive development in children.

3. Review of Empirical Studies

Nutrient Deficiency

• Smith & Johnson (2015) found that iron deficiency negatively impacted cognitive development in a study of 500 children. The children with iron deficiency showed lower scores in attention and memory tests compared to their well-nourished peers.

Balanced Diet

• Lee & Davis (2016) reported that children with balanced diets had better cognitive performance in a survey of 700 elementary students. The study highlighted the importance of vitamins and minerals in supporting brain function and development.

Supplementation

• Brown & Miller (2017) showed that omega-3 supplementation improved attention and memory in a study of 300 children. The children who received omega-3 supplements performed better in cognitive tasks than those who did not.

4. Methodological Review

Studies used surveys, longitudinal designs, and experimental methods. Surveys provided broad data but were limited by self-report biases. Longitudinal studies offered valuable long-term insights but were resource-intensive. Experimental methods showed causation but had limited external validity.

5. Synthesis and Critique

The literature indicates that proper nutrition significantly impacts cognitive development in children. Nutrient deficiencies can impair cognitive functions, while balanced diets and supplementation can enhance them. However, findings vary based on study design and population. More longitudinal and controlled studies are needed to confirm these effects and understand the underlying mechanisms.

6. Conclusion

Current research supports the crucial role of nutrition in cognitive development, emphasizing the need for balanced diets and proper nutrient intake. Further research is necessary to explore long-term impacts and develop effective nutritional interventions.

Furiosa Crystalizes the Power—and Limits—of Cli-Fi

The title card that opens 1979’s original Mad Max places the action in a very near future, looming just “a few years from now.” George Miller’s cult action-thriller captured the edginess of a world teetering on the brink. The film depicts a not-quite-postapocalyptic Australia, where gangs of high-octane galoots rove the roadways on motorbikes and souped-up muscle cars, attempting to outrun the last of the lead-footed policemen: Mel Gibson’s Max Rockatanksy. Revisiting the film is exceptionally rewarding—and not just because of the grit, oddball humor, and verve of Miller’s directing. It reflects something of the ambient tensions of a world of potentially perilous fuel shortages, which threatened the whole petrol-and-plastic framework of our modern world.

Miller recalls this era with no particular fondness. He remembers, in the mid-’70s, all of the gas stations in Melbourne shutting down. Save for one. The mood was sour. The tension was thick. “It only took 10 days,” Miller says, “in this very peaceful, benign city for the first gunshot to be fired. Someone got ahead of a long queue, that went on city blocks, to get fuel. If that could happen in just 10 days, what would happen in 100 days?”

Across five films, including the new Furiosa: A Mad Max Saga , Miller’s franchise tracks this decline. In the original picture, the world is still fairly intact. There are diners and hospitals and happy families. People even dress more or less normally. It can feel a bit like our world: one which is collapsing but hasn’t yet totally buckled. By the time of 1982’s Mad Max 2 (released in the US as The Road Warrior ), any vestiges of civilization have been blown away by an accelerated period of resource warring, nuclear conflict, and ecocide. Humanity survives in clans and roving bands, dressed in feathers and dusty leathers.

By 1985’s Mad Max: Beyond Thunderdome , civilization relies on bartering for commerce, harvesting pig shit for methane, and conflict resolution by way of gladiatorial combat. In the smash hit 2015 long-gap sequel, Mad Max: Fury Road (which recast Rockatanksy, putting Tom Hardy in the lead), things were almost cartoonishly bad: Fertile women were ferried across vast wastelands in tanker trucks, access to fresh water was hoarded by tyrannical dictators in skeleton half-masks, and all of humanity seemed to exist in a state of berserk, whooping madness. If that first film was warning—against the fetish for speed and power, against excessively extracting precious riches from a planet that could scarcely afford to give them up—the newer pictures feel not so much prescient as present: sado-comic visions of our own maddening, resource-starved world.

The Mad Max films are driven by a guiding incoherence. They offer a critique of car culture, resource scarcity, and the very things that may well have our world motoring toward its own demise, no matter how many EVs we buy. Denizens of the desolate wastelands exalt automobiles, motorbikes, engines, and especially gasoline as fetish objects. But at the same time, the films’ pleasures are guilty of this same exaltation. The thrills derive from high-octane racing, dangerous automobile maneuvers, body-mangling crashes, and the whole vroom-vroom of it all. They’re like war movies that ask us to thrill at the violence and daring of combat, while all the while muttering, “This is actually really awful, you know.” There is no effort to reconceive a world doomed by its pathological obsession with machines chugging on crude oil. Rather, the apocalyptic backdrop only furnishes fantasies of further decline.

Perhaps it’s a mistake to take films with characters called “Pig Killer,” “Rictus Erectus,” and “Pissboy” too seriously. But the Mad Max pictures underscore a deeper absurdity that undergirds the genre of postapocalyptic, ostensibly environmentalist (or at least environmentally sympathetic) entertainments that are often referred to as eco-fictions, or cli-fi, for “climate fiction.” “The climate crisis and grotesque climate inequalities are things that we are really struggling to process,” says Hunter Vaughan, an environmental media scholar at Cambridge University. “These films are touching on our collective inability to adapt to this crisis.”

Vaughan is the author of Hollywood’s Dirtiest Secret: The Hidden Environmental Cost of the Movies . His text analyzes the environmental impact of the film industry, from early Hollywood to the present. Understanding the industry as inherently (and devastatingly) resource-reliant, he has come to view the very idea of “environmentalist movies” as a bit of an absurdity. “Films like Mad Max and Avatar ,” he explains, “are just doing what Hollywood has always done, which is rely on choreographed violence and the enticement of spectacle. But they get to offset that to some degree by coming across as having some sort of environmentalist message.”

The whole notion of “cli-fi” as a genre suggests something a bit ominous: that the well-meaning parables of early climate fiction have now become subservient to the demands of the genre. Take Denis Villeneuve ’s Dune pictures. While perfectly competent as pricey pieces of blockbuster cinema, they barely engage with the novel’s ecological concerns. Author Frank Herbert was originally inspired by the historical ability of certain indigenous civilizations to live in harmony in even the harshest environments—a noble idea that, in the Hollywood version, takes a backseat to woolly ideas around interstellar jihad and the sheer pageantry of the proceedings. Likewise, Mad Max 's original warning siren has waned a bit, as the films developed their own generic language. The collapsing world is now just a canvas across which (wildly entertaining) action scenes unfold.

However absurd it may seem to scholars, Miller seems to come by his environmentalist sympathies honestly. Even outside of the Mad Max movies, many of his pictures touch resonant themes about global warming ( Happy Feet ), vegetarianism ( Babe and its sequel), and the essential destructiveness of the modern world ( Three Thousand Years of Longing ). These realities have directly impacted his films. Fury Road ’s production was long delayed, in part, because the Australian desert where Miller planned to film was suddenly swamped—a direct result of unpredictable climate patterns. “I see it myself,” the director says of climate change. “It’s all around us. I’ve seen both the hard statistics, and just in my own experience. So it can’t help but seep into the story.”

Furiosa is unique among the Mad Max films in that it offers an alternative to the arid, violent, boiling wastelands that dominate the franchise’s topography. The origin story of Charlize Theron’s fierce road warrior from Fury Road , the film opens in “the Green Place”: an Edenic garden governed by a tribe of warrior-women, which stands out as a lush oasis in the desert. For Miller, Furiosa offered an opportunity to one-up himself. Fury Road proved he could make a hit Mad Max movie without Mel Gibson. Now, he hopes to show he can make another without Max (though he does appear, very briefly). “If you just do the same thing again and again, there’s hardly any point,” he says. “There’s an inherent cynicism to it.”

Snatched from safety, Furiosa (played by Ayla Browne as a child and Anya Taylor-Joy as an adult) is raised among a motorcycle death cult, led by the madman-prophet Dementus (Chris Hemsworth, sporting an impressive prosthetic schnoz). In time, she’s traded away to Immortan Joe, Fury Road ’s big bad, and learns to survive and thrive among his clan of face-painted, aerosol-huffing cultists. Building out the world of Fury Road , Furiosa traces the fragile trade dynamics between three strongman leaders, each hoarding a key resource: fresh water, fuel, and bullets. As Furiosa navigates these violent trade routes, she hatches her own plan to avenge herself on Dementus and burn rubber back to the Green Place.

In actually bothering to imagine what some alternative to the wasteland might look like, Furiosa moves past the typically narrow horizons of most cli-fi. Nicole Seymour, who teaches environmental literature at California State University, Fullerton, notes that most environmentalist narratives stop short of actually conceiving of what a new, better world might look like. “I think that would require you to do more implicating, and more work,” she says, “which no one wants to do.” She notes that most utopian environmentalist literature tends to buck the mainstream, foregrounding more diverse characters. “Do they want to make a movie about a Puerto Rican transgender person who time-travels?” she asks. “I would watch that!”

There’s a shopworn quote attributed to the late critic and theorist Mark Fisher, about how “it's easier to imagine the end of the world than the end of capitalism.” Certainly, in the Mad Max movies, the basic systems that led to our destruction—resource hoarding, the primacy of tribal violence, the fetish for power and speed—remain intact. The sinister logic imparted to the audience is that, well, ecocide is inevitable, and so there’s little left to do than revel, laughing mad, in the explosive spectacle of our own destruction. To which an admirer of these films (like this writer) may sensibly, or cynically, respond: OK, sure … but what a spectacle.

For his part, Miller maintains that there’s a deep humanism at the core of these films, buried beneath the scrap heaps of twisted metal. “I’ve been to places where there is a lot of trauma and poverty,” he says. “I’m always impressed by the ability for survival. This is about our survival.”

Restaurant Review: ‘New Nordic’ Isn’t New, but ILIS Adds a Fresh Spin

Mads Refslund’s creative ideas at this Brooklyn restaurant can be dreamily seductive, even if the execution isn’t always as compelling.

By Pete Wells

The most talked-about dish at ILIS, the cavernous Brooklyn restaurant opened by the Danish-born chef Mads Refslund in October, has to be the clam flask. This is a drinking vessel made by opening a surf clam, removing the clam, resealing the halves of the shell and shearing off a bit of the top lip to create a small opening through which you sip the liquid inside.

When I first had the clam flask, it was filled with a blend of tomato juice and dried-clam broth that tasted something like a virgin Caesar cocktail. The contents, though, are not what has captured everybody’s attention. The reason everybody remembers the flask is that it is tightly bound and knotted with twine, like a corset designed for bivalves with a taste for mild kink.

Mr. Refslund’s cooks must spend a good part of the workweek at the arts-and-crafts station. An Okinawan sweet potato is presented in a fluted tart shell molded from beeswax. Chopped whelk in potato foam is nestled inside the shell and is eaten with a birch stick lashed to an operculum, the part of the whelk that normally seals the shell’s opening and looks something like a guitar pick.

This use of natural materials in the kitchen is one of the hallmarks of the New Nordic style that Mr. Refslund helped found, and the handmade pieces at ILIS have a certain spooky pagan beauty. They cast a spell over all my meals there, a daydreamy state so pleasant that I didn’t want to admit that many of the dishes weren’t really landing the way they should.

A similar spell must have fallen over the writers and influencers who have been talking about ILIS as if it were a New York City branch of Noma . It’s far from that. Mr. Refslund and René Redzepi served as co-chefs of Noma when it opened in 2003 in Copenhagen. After about six months, they agreed that they weren’t cut out to work together, and Mr. Refslund left. He doesn’t try to claim credit for what Noma became , but a lot of people in New York seem eager to give it to him.

The food at ILIS doesn’t resemble any of the dishes I ate at Noma six years ago, each of which pulsed with flavor and originality and was as satisfying as a great pop song or short story. Some of the cooking at ILIS is heading in that direction, but a lot of it tastes wispy and unfinished.

The people comparing ILIS to Noma almost act as if Mr. Refslund and New Nordic cuisine itself were both new to the city. In fact, 12 years ago he was the opening chef of Acme , the restaurant that really did give the city its first taste of the naturalistic, intricate new style. (Not long after, Fredrik Berselius opened the pop-up version of Aska , which has grown into the most impressive local showcase for that cuisine.)

Some items on that menu were forerunners of dishes at ILIS. Ollebrod, a yeasty Danish porridge of dark beer and rye bread, has appeared on the dessert lineup at both restaurants, and so has some version of a granita made from wheatgrass juice.

As he did at Acme, Mr. Refslund builds his menu at ILIS from regional ingredients, but his knowledge of what’s available locally has grown considerably. New Nordic cuisine is less a regional style than a belief system that can be applied almost anywhere. One of its tenets is that we’re surrounded by a vast catalog of wild foods far beyond the small handful of domesticated plants and animals that make up most European and American diets.

In recent weeks the kitchen at ILIS was playing around with blood clams, their hemoglobin-rich juices gathered around them in an alarming red pool; Japanese knotweed, an invasive species that will quickly choke any lot where it takes root but, when picked young enough, tastes tart and fresh; or propeller-like maple seedlings clinging together in purple clusters.

There’s a good chance you’ll run into something new at ILIS, though some of these discoveries are more exciting than others. I was genuinely happy to be introduced, by way of a whole roasted breast and skewers of grilled kofta made from the legs, to the deep flavor of Khaki Campbell ducks, a mallard hybrid that yields leaner and more intensely flavored meat than many other farm-raised ducks. On the other hand, if I don’t gnaw on another raw knotweed shoot until next spring, that will be fine with me.

Each time I ordered sea scallops, servers let me know that they enter the kitchen alive and whole, with their roe. But the sweetness you hope to get from very fresh scallops never quite materialized, whether they were served raw with new spring peas or steamed with dashi and oil made from the roe.

Some courses are almost pure theater. When the sweet potato arrives, a server pours hot beeswax over it and then inverts an hourglass egg timer. This is supposed to signal when the potato is ready to eat, but the heat from a thin coat of wax can’t possibly be strong enough to finish cooking a whole sweet potato. Once this ritual is over, the potato is sliced in half and a big lump of caviar is dropped on one half. You’re supposed to eat the other half with salt. Salt and caviar will make almost any potato taste good, and this one is unusually creamy, its purple flesh as dense and soft as a ripe nectarine, but the jazz-hands presentation oversells it.

Then there is the whole cauliflower brought to the table in the pig’s bladder in which it is cooked. This is a version of a famous French chicken dish, an early method of sous-vide cooking that uses the bladder to seal in moisture so the chicken steams in its own juices. Cauliflower doesn’t have juices, though. Mr. Refslund adds a seaweed stock to the bladder for seasoning and then spoons herb vinaigrette over the florets, but when the bladder is carried to your table and snipped open with scissors, what comes out still tastes like steamed cauliflower.

It’s true that ILIS has served me some of the most memorable dishes I’ve eaten in a long time. I was kind of blown away by the bigeye tuna loin cured in seaweed and salt for months and then sliced thin like aged ham, which the fish resembles in its vivid pink color and focused intensity. I am fascinated by the exceptionally silky raw-milk cheese that the kitchen makes each day and accented one night with shaved asparagus and pickled lily bulbs. And many of the things that came off the grill were riveting, including the sea bream brushed with black-olive sauce and Texas antelope speared on a stick with wild-boar lardo.

With a dish like that in your hands, you can believe that you really are in one of the best new restaurants of the past year. Then you find yourself wondering why the liquid in the clam flask is tepid, even though it’s served on ice; why the scallops aren’t as sweet as they could be; why the brussels sprouts that accompany grilled brown trout are so weird and gloppy.

ILIS isn’t the American Noma, and it’s not meant to be. It could become something important, though, if the cooking ever gets to be as dramatic as the stagecraft.
