How academic journals work, how peer review evaluates research before publication, and how to read a scholarly article strategically for exactly what your research needs
This chapter teaches you how to identify, read, and evaluate scholarly articles. You will learn what peer review means, why it matters, how academic journals work, how scholarly articles are structured, and how to read them strategically so you spend your time on what is most useful to your research question.
Scholarly articles are one of the most reliable source types available for academic research. They are written by researchers and experts, reviewed by other specialists before publication, tied to documented evidence, and built into larger conversations that have been developing across years or decades of published work. When your professor asks for academic sources, scholarly articles are usually what they mean.
But scholarly articles are also demanding. They are written for other specialists, not for general audiences. They use technical vocabulary, assume background knowledge, and present detailed evidence that takes time to work through. Many students open a scholarly article, feel overwhelmed, and either abandon it or copy a sentence from the abstract without reading the rest.
This chapter teaches you to work with scholarly articles as a practical skill, not as a performance. You do not need to understand every sentence to use a scholarly article well. You do need to understand how the article is built, what each section does, and how to extract the information your research actually needs.
Understanding peer review also protects you from being misled. Not everything labeled "research" has been peer reviewed. Reports, white papers, opinion pieces, think-tank publications, and even some journal articles have not passed through independent expert evaluation. Knowing how peer review works helps you judge source quality accurately instead of accepting any source that looks official.
Imagine two students are each asked to find one source on whether a new reading intervention improves comprehension in elementary students. The first student finds a magazine article describing the program with enthusiastic quotes from a school principal. The second student finds a peer-reviewed article reporting a controlled study of the program across twelve classrooms, with a methods section, a results table, and a discussion of limitations. Both sources mention the same program. Which source can actually support a claim about whether the intervention works — and how would you know? By the end of this chapter, you will be able to answer that question with confidence, and you will know exactly which parts of a scholarly article to read to find out.
A scholarly article is a written work that presents original research, reviews existing research, or develops a theoretical argument in a specific academic discipline. It is written by one or more researchers who have expertise in the subject, and it is published in an academic journal that is dedicated to that discipline or a related set of fields.
Scholarly articles are different from other written work in several key ways.
| Feature | What It Means | Why It Matters |
|---|---|---|
| Author expertise | Authors have advanced training and are typically affiliated with a university, research institute, or professional organization | Credentials and affiliations are documented, unlike anonymous or unverified writing |
| Peer review | Independent experts evaluate the article before it is accepted for publication | Reviewers check the research question, methods, evidence, and conclusions for soundness |
| Evidence and documentation | Every significant claim is backed by data or by citations to other published research | Readers can trace every claim back to its evidence in the references list |
| Discipline-specific publication | Articles appear in journals focused on a specific field or set of related fields | The audience is other researchers in that field, which shapes the assumed background knowledge |
| Contribution to knowledge | Articles add something new — an experiment, an analysis, a framework, a reading, a synthesis | Published research is expected to advance understanding, not just summarize it |
It is worth noting that not every article in an academic journal is a research article presenting original findings. Journals also publish review articles that synthesize existing research, theoretical pieces that develop frameworks and arguments, commentaries that respond to other published work, book reviews, and short communications. When you are looking for original research, you want empirical articles or theoretical articles, not commentaries or book reviews.
The way scholarly articles are written and structured varies significantly across academic disciplines, and this matters for how you read them.
In the sciences and social sciences, scholarly articles typically follow a standard format: introduction, methods, results, and discussion. This structure reflects the logic of empirical research: here is the question, here is how we investigated it, here is what we found, and here is what it means. Articles in psychology, biology, economics, sociology, and many other fields follow this pattern closely.
In the humanities — including literature, history, philosophy, and art history — scholarly articles look different. There is usually no methods section and no results section. Instead, a humanities article develops an argument through close reading, historical analysis, or philosophical reasoning. Evidence in a humanities article might be a passage from a novel, a document from an archive, or a philosophical text. The structure is more essayistic, and the contribution is usually an interpretation or argument rather than an empirical finding.
In professional and applied fields — including education, nursing, social work, public health, and business — scholarly articles may combine elements of both styles. They often report empirical research but are also concerned with practical implications and policy recommendations.
Before you open an unfamiliar article, check the discipline of the journal. If it is a science or social science journal, expect an IMRaD structure (Introduction, Methods, Results, and Discussion). If it is a humanities journal, expect an essay-style argument without those labeled sections.
Understanding which tradition your research question sits in helps you know what kind of scholarly articles to look for and how to read them when you find them.
An academic journal is a periodical publication that contains scholarly articles in a specific discipline or set of related disciplines. Journals are typically published by academic presses, professional associations, or scholarly societies. They appear on a regular schedule — monthly, bimonthly, quarterly, or annually — and they are identified by volume and issue numbers.
Understanding how journals are organized helps you read citations correctly, search databases more effectively, and evaluate sources accurately.
Each journal has a name that typically reflects its focus. Journal of Educational Psychology, American Historical Review, The Lancet, and Journal of the American Chemical Society are all examples. The name tells you something about the discipline and, often, the geographic or institutional affiliation of the journal.
Journals are organized by volume and issue. A volume usually corresponds to a year of publication. Each volume contains multiple issues. When you see a citation like "Journal of Applied Linguistics, 12(3), 45–67," it means volume 12, issue 3, pages 45 through 67. This information helps you locate the article in a library database or physical collection.
Academic journals are governed by editorial boards composed of scholars in the field. An editor-in-chief or a team of editors makes final decisions about which articles are accepted. Associate editors and assistant editors may handle specific subject areas or manage the peer review process for individual submissions.
Most journals are published by commercial publishers, academic presses, or professional associations. Commercial publishers like Elsevier, Springer, Wiley, and Taylor & Francis publish large numbers of journals across many disciplines. Academic presses like Oxford University Press, Cambridge University Press, and MIT Press publish journals along with books. Professional associations like the American Psychological Association, the Modern Language Association, and the American Medical Association publish journals tied to their fields.
Not all journals have equal standing in their fields. Researchers generally value publication in high-prestige journals because it signals that their work has passed rigorous review by leading scholars.
One measure of journal prestige is the impact factor, a calculation based on how frequently articles in that journal are cited by other researchers. A journal with a high impact factor is being cited frequently, which suggests its articles are influential. However, impact factor is not a perfect measure of quality, and it varies significantly across disciplines.
Being published in an academic journal does not guarantee that an article is correct, comprehensive, or the final word on a topic. Peer review catches many problems, but it does not catch everything. Significant research can be published in less prestigious journals. Flawed research has appeared in prestigious ones. Use peer review status as one indicator of quality, not the only one.
Traditional academic journals are often available only through subscriptions paid by libraries or individuals. A researcher at a well-funded university can access thousands of journals through their library's subscriptions, but a student at a smaller institution or a member of the public may find many articles blocked behind paywalls.
Open access journals make their articles freely available to anyone with internet access. The open access movement has grown significantly in recent years, driven by the argument that publicly funded research should be publicly available. Many open access journals are rigorous and respected. Others are less so.
A concern in open access publishing is the rise of predatory journals: publications that charge authors fees to publish without providing genuine peer review or editorial oversight. Predatory journals mimic the appearance of legitimate journals but do not actually evaluate article quality.
You can identify potential predatory journals by checking whether the journal appears in established databases like JSTOR, PubMed, or EBSCO; whether its editorial board includes real, verifiable scholars; whether it publishes work across a credible range of topics; and whether it is associated with a recognized publisher or professional association. When in doubt, ask a librarian.
Peer review is the process by which scholarly articles are evaluated by independent experts in the field before being accepted for publication. It is the central quality-control mechanism of academic publishing.
Understanding peer review helps you appreciate why scholarly articles are generally more reliable than non-reviewed sources, and why peer review status is not a guarantee of perfection.
When a researcher submits an article to a journal, the editor first performs an initial review to determine whether the article fits the journal's scope and meets basic standards. Many articles are rejected at this stage without going through peer review. If the article passes initial review, the editor sends it to two or more experts in the subject area — the peer reviewers, who are typically scholars who have published work in the same or related areas and are not paid for this service.
Reviewers read the article carefully and evaluate it against a set of criteria. They consider whether the research question is meaningful and original, whether the methods are appropriate and sound, whether the data or evidence actually supports the conclusions, whether the literature review accurately represents existing knowledge, whether the writing is clear and well-organized, and whether the conclusions are justified.
This is one reason why newspaper and magazine sources often cover new research before the full scholarly article is available: journalists report on findings as they emerge, while the scholarly version is still working through the review process.
| Type | How It Works |
|---|---|
| Single-blind | Reviewers know the authors' identities; authors do not know the reviewers'. Most common form; protects reviewers but may introduce bias related to authors' reputations. |
| Double-blind | Both parties are anonymous. Reduces some bias but is harder to implement consistently. |
| Open | Reviewers' identities are known to authors, sometimes the whole process is public. Proponents argue this improves accountability. |
| Post-publication | The academic community comments on and evaluates articles after publication. More common in some fields and platforms than others. |
Peer review improves article quality. Reviewers catch errors in reasoning, flag unsupported claims, identify missing literature, and push authors to clarify unclear passages. The version of an article that reaches publication is almost always stronger than the initial submission.
But peer review is not infallible. Peer reviewers are human, with their own biases and blind spots. A reviewer deeply committed to one theoretical framework may evaluate an article through that lens in ways that disadvantage work from a different perspective. Reviewers may miss statistical errors, cannot detect skillfully fabricated data, and may not catch misrepresented citations.
Several high-profile replication crises — particularly in psychology, medicine, and economics — have revealed that some published, peer-reviewed findings cannot be reproduced by other researchers. This does not mean peer review is useless. It means that peer review is one layer of quality control, not a guarantee of truth.
Treat peer-reviewed articles as more reliable than non-reviewed sources, while still reading them critically. Ask whether the methods make sense, whether the sample size is adequate, whether the conclusions are proportionate to the evidence, and whether the findings have been replicated or challenged by other research.
Most scholarly articles in the sciences and social sciences follow a predictable structure. Learning what each section does allows you to read articles strategically: you can identify relevant articles quickly, understand their core arguments efficiently, and extract the information you need without reading every word from beginning to end.
The abstract is a brief summary of the entire article, usually between 150 and 300 words. It appears before the article itself, which is why it is often available even when the full article is behind a paywall.
A well-written abstract tells you the research question, the methods used, the main findings, and the key conclusions or implications. Reading the abstract lets you decide whether an article is relevant to your research question before investing time in the full text.
The abstract is a summary, not the source itself. If the abstract seems relevant, read at least the introduction, methods, and discussion before deciding how to use the article in your research. Structured abstracts, common in medical and psychology journals, divide the summary into labeled sections — Background, Methods, Results, and Conclusions — making it even easier to locate specific information quickly.
The introduction does several things. It establishes the topic and explains why it matters. It reviews the relevant existing literature to show what is already known and what remains unclear or contested. It identifies the gap in knowledge that the article addresses. And it states the research question, hypothesis, or purpose of the study.
When you are reading an article for research purposes, the introduction helps you understand what the researchers were trying to find out, what existing research they were building on or challenging, and why this question is considered important in the field. The literature review embedded in an introduction is also a useful research tool — the sources cited there are likely relevant to your topic, which means you can use the introduction's citations to find additional sources.
The methods section describes how the research was conducted. In a quantitative study, this section explains who the participants were, how they were selected, what materials or instruments were used, what procedures were followed, and how the data were analyzed. In a qualitative study, it describes the data sources, the data collection approach, and the analytical framework. In a historical or archival study, it identifies the sources examined and explains how they were selected and interpreted.
The methods section is the part of a scholarly article that most clearly distinguishes it from non-scholarly writing. The requirement that researchers explain their methods in enough detail that others could replicate or evaluate the study is fundamental to the credibility of academic research.
What kind of evidence did the researchers actually use? How representative or generalizable might the findings be? Was the study design appropriate for the question being asked?
You do not need to understand every technical detail to use the article effectively, but you should be able to answer: What did they actually do? Did the method match the question?
The results section presents the findings of the study without interpretation. In quantitative research, this typically means tables, charts, and statistical analyses. In qualitative research, it may present themes, categories, or patterns identified in the data, often illustrated with direct quotations from participants or documents.
Results sections can be dense and technical. Focus on the summary statements, the tables and figures with their labels and captions, and the key findings the authors highlight. Pay attention to the relationship between what was found and what was claimed. Do the results actually show what the authors say they show? Are there alternative interpretations the authors do not discuss?
The discussion section is where the authors interpret their findings, explain what they mean, connect them to the existing literature, acknowledge limitations, and draw conclusions. This is often the most intellectually rich section of an article. In the discussion, authors typically explain how the findings answer the research question, compare findings to previous research, discuss alternative explanations, acknowledge limitations, explain implications, and suggest directions for further research.
For most research purposes, the discussion section is where you will find the most useful material.
Some articles include a separate conclusion section after the discussion. In others, the discussion ends with concluding statements. A conclusion summarizes the key findings, restates the significance of the research, and may offer final recommendations.
The references list at the end of the article documents every source cited in the text. This list is one of the most valuable features of a scholarly article for your research — every source there is something the authors considered relevant and credible enough to cite. Reading through references is a technique called citation chaining, covered in detail in Chapter 22 and again in Section 13.6 below.
Every research article contains some form of literature review, usually in the introduction. A literature review is a synthesis of existing published research on a topic. It establishes what is already known, identifies what remains unclear or contested, and provides the context that makes the new research meaningful.
Understanding literature reviews helps you use scholarly articles more effectively, because the literature review in an article is essentially a curated map of the field that the authors have already built for you.
A literature review in a scholarly article accomplishes several things. It shows that the authors know the field — before conducting new research, scholars are expected to thoroughly understand what previous research has found. It establishes the gap, identifying what is not yet known or what remains debated. It positions the new research, explaining how the new study relates to existing work — whether it replicates a finding, challenges a previous conclusion, synthesizes conflicting results, or extends a line of inquiry. And it gives readers context, providing the background needed to understand why the research question matters.
In addition to the literature review sections embedded in research articles, some scholarly articles are themselves literature reviews. A systematic review or meta-analysis is a rigorous synthesis of all the published research on a specific question, following explicit methods for identifying, selecting, and analyzing the relevant studies. A narrative review covers the literature on a topic in a less formally systematic way, offering the authors' synthesis and interpretation.
If you find a recent systematic review or meta-analysis on your topic, it can save you significant search time and give you a reliable foundation for understanding the field — often with an assessment of how strong the underlying evidence actually is.
Scholarly articles do not exist in isolation. Every published article is part of an ongoing conversation in the discipline — a conversation that develops over years and decades through published responses, replications, criticisms, extensions, and revisions.
Understanding scholarly citation practices helps you trace these conversations, evaluate how well-supported a finding is, and navigate from one useful source to many others.
When a scholar cites another work, they are giving credit to the original authors, directing readers to supporting evidence, signaling serious engagement with the existing literature, and positioning their own work in relation to that literature — agreeing with it, extending it, qualifying it, or challenging it.
Backward citation chaining means following the references cited in an article back to earlier sources. If an article published in 2023 cites a key 2015 study, you can locate that 2015 study, read it, and find the earlier sources it cited. This lets you trace a line of research back toward its origins.
Forward citation chaining means finding later articles that have cited a particular source. If you find a useful 2015 article, you can use a database tool like Google Scholar's "Cited by" feature to find articles published after 2015 that cited it. This lets you trace how a piece of research has influenced later work.
Used together, these two techniques allow you to map a scholarly conversation: who built the original foundation, who has engaged with it since, and where current debates stand.
Not all citations in a scholarly article are equally important. Some are cited because they provide foundational theory or methods in the field — work that everyone in the discipline knows and builds on. Others are cited because they are recent contributions to a specific question. Others are cited to be acknowledged and dismissed (the "despite claims by X" pattern).
When you are looking for sources to use in your own research, pay attention to which works are cited frequently across multiple articles on your topic. Frequently cited works are likely to be foundational in the conversation. You may want to read them directly rather than only encountering them through other sources.
The strengths of peer-reviewed scholarly articles are significant. So are the limits. Understanding both makes you a more effective and honest researcher.
| Strength | Why It Matters |
|---|---|
| Expert evaluation | Reviewers know the field deeply enough to identify errors in reasoning, methods, and evidence that a general reader would miss |
| Documented evidence | Every claim must be supported by cited evidence or by data the authors collected, so claims can be traced back to their sources |
| Transparency of methods | The methods section allows other researchers to evaluate the study design and, in principle, replicate it |
| Cumulative knowledge | Findings are replicated, challenged, refined, and synthesized over time, producing an increasingly reliable body of knowledge |
| Accountability | Journals can publish corrections or retractions when errors are discovered — a mechanism non-reviewed sources lack |
| Limit | What It Means for Your Research |
|---|---|
| Publication bias | Studies with significant results are more likely to be published than null-result studies, which can distort the published picture of the evidence |
| Slow process | A finding may not be published until a year or two after the research was completed; in fast-moving fields, published articles may already be outdated |
| Replication problems | In some fields, significant numbers of published findings have not replicated when other researchers attempted them |
| Reviewer bias | Reviewers may favor articles aligned with dominant paradigms or prestigious institutions, disadvantaging unconventional approaches |
| Uneven quality | Review rigor varies across journals and disciplines; being peer reviewed is not the same thing across all publications |
| Access barriers | Many peer-reviewed articles require expensive subscriptions, creating unequal access to knowledge |
Understanding these limits does not mean you should distrust peer-reviewed research. It means you should read it carefully, consider whether findings have been replicated or challenged, and treat even prestigious scholarly sources as evidence in an ongoing conversation rather than as final truths.
Reading scholarly articles is a skill. Like any skill, it improves with practice. But there are specific strategies that help you work through dense academic writing more efficiently and extract what you actually need.
Before you open an article, know why you are reading it. Are you looking for background on a topic? Trying to find specific data or a specific finding? Trying to understand how scholars frame a particular debate? Looking for a theoretical framework? Looking for a list of relevant sources? Your purpose determines how much of the article you need to read and in what order.
Always read the abstract before deciding to read the full article. The abstract tells you whether the article is actually relevant to your question. If the abstract does not indicate relevance, move on. Do not invest time in reading an article that will not be useful. If the abstract indicates relevance, move to the introduction.
The introduction tells you what the researchers were trying to do and why. It orients you to the literature and gives you context for the methods and findings. Read it thoroughly.
If you are trying to understand what the article found and what it means, read the discussion section before working through the methods and results. The discussion translates the findings into plain language and explains their significance. Once you understand the conclusions, the methods and results sections become much easier to follow.
This approach is especially useful when the methods or results sections are highly technical. Reading the discussion first gives you a framework for understanding what the numbers or analyses are supposed to show.
Once you understand the conclusions, read the methods section to evaluate whether those conclusions are warranted. Did the researchers actually measure what they claim to have measured? Was the sample size adequate? Was the comparison group appropriate? Was the analysis well-suited to the data?
You do not need to understand every statistical technique to evaluate basic methodological fit. If a study claims to show that a particular intervention improves student outcomes but only studied 12 students with no control group, the conclusion may be overstated regardless of the statistics.
Tables and figures often present the data more clearly than the text does. Read the labels and captions carefully. Ask what the table is showing and whether it shows what the authors say it shows.
Scan the references list for sources you recognize or might want to follow up on. The references are a curated list of sources the authors found credible and relevant. It is one of the most useful features of a scholarly article for your own research.
As you read, take notes using the MGU Research Note Model:
Recording this information while you read saves significant time when you begin writing.
If you have a PDF of the article, use the annotation tools to highlight key passages, add comments, and flag sections for follow-up. Even simple highlighting — using different colors for key findings, methodological concerns, and quotable passages — helps you find important material when you return to the article later.
Choose a research topic you are currently working on or interested in, such as the effects of sleep deprivation on memory, the history of public libraries, or the economic impacts of urban green spaces.
Open Google Scholar (scholar.google.com) or another academic database you have access to, such as JSTOR, PubMed, or EBSCO. Search for your topic. After you receive results, identify three articles that appear to be peer-reviewed scholarly articles. For each one, record the title, the author(s), the journal name, the year of publication, and whether you can access the abstract, the full text, or both.
Now compare your three articles. Which appears most relevant to a specific research question? Which was published most recently? Which is from the most specialized journal?
Find an abstract for a scholarly article on any topic. Read it carefully and identify the research question or purpose, the methods used, the main finding, and the conclusion or implication.
Write one or two sentences summarizing whether this article would be useful if your research question were: How do researchers measure [your topic] in real-world settings?
Find a scholarly article on your topic that was published at least five years ago. Look at its references list and identify three sources cited there that seem relevant to your research question.
For each source, write down the full citation information. Then check whether you can locate at least one of those sources in a library database.
Imagine you are researching the relationship between social media use and adolescent mental health. You find an article with the following characteristics:
| Title | "Screen Time and Depressive Symptoms Among Adolescents: A Longitudinal Analysis" |
| Authors | Dr. A. Nkemdirim and Dr. P. Reyes, both affiliated with a university psychology department |
| Journal | Journal of Adolescent Health |
| Year | 2021 |
| Method | Survey of 1,200 high school students across three schools over two years |
| Finding | Students reporting more than four hours per day of social media use showed higher rates of depressive symptoms at follow-up, even after controlling for prior depression scores |
Apply the MGU Source Evaluation Model:
This is a credible, relevant, and useful source. Its limitations (self-reported data, three schools only) should be acknowledged when you use it. Consider looking for other studies that confirm or challenge this finding.
When you read a scholarly article, record information systematically using the MGU Research Note Model. Here is a completed example based on a hypothetical article:
Always record the DOI (Digital Object Identifier) when one is available. The DOI is a permanent link that will work even if a website moves or changes.
A common misconception is that if something is published in a peer-reviewed journal, it must be true. This is not the case. Peer review improves quality but does not eliminate error, bias, or fraud.
Watch for these situations:
One peer-reviewed study is evidence, not proof. Be skeptical of news headlines claiming "A new study proves..." A single study, even a well-designed one, rarely proves anything definitively. Look for replication and consistency across multiple studies.
Some publications look like legitimate peer-reviewed journals but do not actually conduct peer review. They charge authors fees to publish without editorial evaluation. Check whether the journal appears in established databases and whether its editorial board includes real scholars.
Sometimes articles are published and later retracted because of discovered errors, data problems, or fraud. Before citing a study, check whether it has been retracted. The Retraction Watch database tracks retracted articles.
A peer-reviewed finding on one population may be overstated as a general truth. A study conducted with college students in one country may not apply to everyone. Read the methods section to understand who the study actually examined.
Positive findings are more likely to be published than null results. The published literature on many topics overrepresents studies that found an effect. This does not mean the effect is not real, but it means you should look for meta-analyses that try to account for publication bias.
The appropriate response to these cautions is not to distrust peer-reviewed research. It is to read it carefully, look for consistency across studies, consider the limitations, and treat scholarly articles as evidence in an ongoing conversation rather than as final answers.
Scholarly articles require careful citation. The most common errors in citing journal articles are listed below.
| Common Error | What to Check |
|---|---|
| Missing the DOI | Always record the Digital Object Identifier when available — it is a permanent locator for the article |
| Wrong volume and issue numbers | Journal articles are identified by volume, issue, and page numbers; these must be accurate |
| Incorrect author name formatting | APA lists authors by last name and initials (Smith, J. K.); MLA lists the first author last-name-first, others first-name-first |
| Missing page numbers | Required for most citation styles; for online-only articles, check for article numbers or e-location identifiers |
| Citing the abstract rather than the article | If you only read the abstract, you cannot cite the article as if you read it — read enough to accurately represent the finding |
Chapter 13 examined scholarly articles as one of the most reliable and rigorously reviewed source types available to researchers. Chapter 14 turns to a different but equally important category: popular and journalistic sources. You will learn how news reports, feature articles, opinion columns, magazines, blogs, and explainers can serve a research project when evaluated carefully — and why these sources, despite lacking formal peer review, often cover breaking developments and public debates faster than scholarly publishing can. Understanding both source types, and knowing when each is appropriate, is central to building a well-rounded body of evidence.
