Ngozi had been staring at her laptop screen for three days straight.
She was a 400-level Mass Communication student at the University of Nigeria, Nsukka, and her project supervisor — a stern, bespectacled man who had been lecturing since before she was born — had returned her draft with exactly four words written in red ink at the top of Chapter Two: “This is not acceptable.”
No further explanation. Just four words and a dismissive wave of his hand.
Ngozi had written almost eight pages. She had gone to Google, typed her topic — “The Influence of Social Media on Political Participation Among Nigerian Youths” — and spent two days copying summaries of articles she found online. She had arranged them one after the other, author by author, paragraph by paragraph. She thought she had done a thorough job. She had names, dates, titles, page numbers. What more could he possibly want?
What Ngozi did not know — what nobody had sat down to explain to her — is that a literature review is not a collection of summaries. It is not a parade of what other people wrote, arranged in a queue. A literature review is an argument. It is a conversation you are having with the scholars who came before you. It is you, the researcher, standing in the middle of decades of knowledge and making sense of it — pointing out what fits, what conflicts, what is missing, and why your own study is the piece that completes the puzzle.
That distinction — between a list of summaries and a genuine literature review — is what separates a project that sails through defence and one that gets returned for the third time. If you are reading this because you are stuck where Ngozi was, you are in the right place. By the time you finish this article, you will understand exactly what a literature review is, how to structure it, what your supervisor actually wants to see, and how to write one that earns you genuine marks.
What Is A Literature Review — And What It Is Not
Let us settle this first, because the confusion here is where most Nigerian students lose their way.
A literature review is a critical, systematic analysis of existing research and scholarship related to your study topic. The keyword is critical. Not critical as in negative — critical as in thoughtful. You are not simply reporting what Author A said and then what Author B said. You are analysing, comparing, contrasting, and synthesising those views to build a foundation for your own research.
Think of it this way. Imagine you are building a house. The literature review is not the list of materials — it is the foundation. Every brick you lay in Chapter Two is supporting the wall you will build in your findings. If the foundation is weak, the house collapses. If your literature review is shallow — just a collection of summaries — your supervisor knows immediately that you do not understand the conversation happening in your field.
What your supervisor wants to see is this: that you have read widely, that you understand what scholars agree on, that you know where the disagreements lie, that you can identify the gaps those disagreements create, and that your study is positioned to address one of those gaps. Everything else flows from that.
A literature review is not:
- A list of book summaries
- A collection of quotations from articles you barely read
- Something you can write in one day using only Wikipedia and Google
- The same as a bibliography or reference list
- Simply “anything related to your topic”
It is:
- A structured argument built from scholarly sources
- Evidence that you understand the intellectual landscape of your field
- The academic justification for why your study is necessary
- The bridge between what others have found and what you intend to find
Why Your Literature Review Matters More Than You Think
In Nigerian universities — whether you are at UNILAG, ABU Zaria, UNIBEN, UNIPORT, or any NUC-accredited institution — Chapter Two carries significant weight in your project assessment. Most departmental grading rubrics assign between 15 and 25 marks to Chapter Two alone. Beyond marks, your defence panel will read your literature review before they read your findings. It shapes how they perceive your intellectual credibility.
There is also a very practical reason. Your literature review is what allows you to write your Chapter One properly — especially your statement of the problem, your research questions, and your significance of the study. If you do not know the existing literature, you cannot know what problem still needs solving. Researchers who skip the literature review and jump straight to data collection often discover during defence that their research questions have already been answered by someone else. That is a painful discovery to make in front of a panel of lecturers.
As the Yoruba proverb says: Ọmọ tí kò gbọ́ ọ̀rọ̀ ìyá rẹ̀, a máa ń tẹ̀lé ìkúnlẹ̀ orí ẹ̀ — a child who does not heed wise counsel will follow the path of their own destruction. The scholars who wrote before you left a trail. Your job in the literature review is to follow that trail, understand it, and then show where it ends — and why your study begins there.
Types Of Sources You Should Be Using
Before you write a single sentence of your literature review, you need to understand what counts as a valid source in Nigerian academic writing. Not everything you find on Google qualifies.
Peer-reviewed journal articles are your most important source category. These are articles that have been reviewed by other experts in the field before publication. Journals like the African Journal of Educational Research, Journal of Law and Jurisprudence, Nigerian Journal of Health Sciences, Journal of Communication and Media Studies, and international journals like those available through Google Scholar all qualify. Your university library — if it has an active subscription to JSTOR, ResearchGate, or HINARI — gives you access to thousands of these.
Textbooks and academic books are valid, especially foundational theoretical works. If you are writing on Mass Communication, works by Wilbur Schramm, Denis McQuail, or Harold Lasswell are legitimate sources. If you are in Law, Niki Tobi’s works on Nigerian constitutional law, or Sagay’s Nigerian Law of Contract, carry serious weight.
Government reports, NUC publications, and policy documents are particularly relevant for Nigerian research. If you are writing about education policy, citing the NUC benchmark standards is legitimate. If you are writing about health, citing FMOH reports adds local relevance.
Theses and dissertations from other Nigerian universities are acceptable, particularly if they are recent and relevant. You can find these through the Nigerian university repository systems.
What you should avoid using as primary sources: Wikipedia, general news articles, personal blogs, unverified websites, and anything without a clear author, date, or institutional affiliation. These are background reading tools — not citation sources.
How To Organise Your Literature Review
This is where most students struggle even when they have good sources. They have the materials but they do not know how to arrange them. There are three main approaches to organising a literature review, and your choice depends on your topic and the nature of the scholarship.
The Thematic Approach
This is the most commonly recommended approach in Nigerian universities and the one most supervisors expect. Instead of arranging your review by author (Author A said this, then Author B said that), you group the literature by themes or sub-topics.
For example, if Ngozi at UNN is writing on “The Influence of Social Media on Political Participation Among Nigerian Youths”, she might organise her review around these themes:
- The concept of social media: definitions and evolution
- Political participation: theoretical perspectives and models
- Social media and youth political awareness in Africa
- Social media and voter mobilisation in Nigeria
- Gaps and contradictions in existing literature
Each theme becomes a subsection in Chapter Two. Within each subsection, she engages multiple authors — comparing what they agree on, pointing out where they diverge, and evaluating the strength of their evidence. By the end, her review reads as a coherent intellectual argument, not a catalogue.
The Chronological Approach
Here you trace how scholarly thinking on your topic has evolved over time — from the earliest studies to the most recent. This approach works well for topics where the field has changed significantly over the years, or where you want to show how a concept has developed.
A Computer Science student at the University of Lagos writing on “Machine Learning Applications in Agricultural Yield Prediction in Nigeria” might use this approach to show how early studies relied on regression models, how later work introduced neural networks, and how recent scholarship is now exploring hybrid approaches — thereby positioning their own study within the cutting edge of the field.
The Methodological Approach
Some supervisors, particularly in science and engineering disciplines, expect a methodological review — where you group literature by the research methods used, evaluating the strengths and weaknesses of each approach and justifying the method you have chosen for your own study. A Public Health student at UNIPORT writing on malaria prevention might group studies by whether they used qualitative interviews, quantitative surveys, or mixed-method approaches, and then explain why their own study adopts one approach over the others.
Most humanities, social science, and law students in Nigeria are expected to use the thematic approach. When in doubt, ask your supervisor directly.
The Structure Of Chapter Two: What To Include
A well-structured Chapter Two in a Nigerian final year project typically includes the following components, though the exact structure may vary by department and institution.
Conceptual Framework
This is where you define and discuss the key concepts in your study. If your topic involves terms like “job satisfaction,” “digital literacy,” “criminal liability,” or “corporate governance,” you define them here — not with a single dictionary definition, but with scholarly definitions from multiple authors. You compare the definitions, note the areas of consensus, and settle on the working definition your study will adopt.
A Business Administration student at ABU Zaria writing on “Employee Motivation and Organisational Productivity in Nigerian Banks” would use this section to define “motivation” — perhaps citing Maslow’s Hierarchy of Needs, Herzberg’s Two-Factor Theory, and McClelland’s Theory of Needs — showing how each theorist conceptualised motivation differently and explaining which framework best applies to the Nigerian banking context.
Theoretical Framework
This section identifies the theory or theories underpinning your study. The theory explains why the relationship you are studying exists. Different disciplines have their foundational theories:
In Mass Communication: Agenda-Setting Theory, Uses and Gratifications Theory, Social Learning Theory.
In Law: Natural Law Theory, Positivism, the Rule of Law doctrine.
In Education: Bloom’s Taxonomy, Constructivist Learning Theory, Piaget’s Theory of Cognitive Development.
In Public Health/Nursing: Health Belief Model, Social Cognitive Theory, Theory of Planned Behaviour.
In Computer Science: Information Processing Theory, Technology Acceptance Model.
In Business Administration: Stakeholder Theory, Agency Theory, Resource-Based View.
You do not just name the theory. You explain it, cite the original theorist, explain how it has been applied in related research, and explain specifically how it guides your own study. Your supervisor needs to see that you chose your theoretical framework deliberately — not randomly.
Empirical Review
This is the heart of Chapter Two — the section where you review actual studies that other researchers have conducted on topics related to yours. This is where Ngozi went wrong. She summarised the studies one by one. What she should have done is engaged them critically.
Here is the difference between a summary and a critical review:
Summary (wrong approach): “Adeyemi (2021) studied the impact of Instagram on Nigerian youth political awareness. He surveyed 300 students at the University of Ibadan and found that 78% of respondents used Instagram to follow political discussions. He concluded that social media is influential in shaping political opinions among Nigerian youths.”
Critical engagement (correct approach): “Adeyemi (2021), in a study of 300 University of Ibadan students, found a significant positive relationship between Instagram use and political awareness, with 78% of respondents reportedly engaging with political content on the platform. While these findings are instructive, the study’s limitation to a single university campus raises questions about the generalisability of the findings to the broader Nigerian youth population, particularly those in non-urban settings where internet access remains uneven (NBS, 2023). Okonkwo and Bello (2022) addressed a similar concern in their cross-regional study, which found that social media’s influence on political participation varied significantly between urban centres like Lagos and Abuja and rural communities in states like Kebbi and Borno, suggesting that the relationship between social media use and political engagement is not uniform across Nigeria.”
Do you see the difference? In the second version, you are doing five things simultaneously: presenting the finding, evaluating the methodology, identifying the limitation, connecting it to another study, and showing the complexity of the issue. That is what a literature review looks like.
As you review empirical studies, you should be asking yourself constantly:
- What did this study find, and was the methodology strong enough to support those findings?
- What are the similarities and differences between this study and others on the same topic?
- What did this study not examine — and is that gap relevant to my own research question?
- Were these findings from Nigerian or African contexts, or are they from Western settings that may not apply directly?
That last point is particularly important. Many Nigerian students cite only foreign studies and ignore African and Nigerian scholarship. Your supervisor notices this. Always prioritise Nigerian and African sources where they exist, and explain when you must rely on foreign studies because local research is thin.
Review Of Related Studies (Some Departments Use This Heading)
Some departments in Nigerian universities distinguish between the “theoretical/conceptual framework” sections and a dedicated “review of related studies” section. In some faculties, particularly in Education and Social Sciences, this section is where you review studies that used similar methodologies or studied similar populations — even if the topic is slightly different from yours. Follow your departmental project writing handbook for guidance on whether your department uses this structure.
Gap In Literature / Summary Of Literature Review
Every strong Chapter Two ends with a section — often titled “Gap in Literature” or “Summary of Literature Review” — where you consolidate what you have reviewed and explicitly state what the existing literature has left unanswered. This is the academic justification for your own study.
This section should answer two questions clearly:
- What do we already know from the existing literature?
- What do we not yet know — and how does my study address that gap?
This section is typically short — between two and four paragraphs — but it must be written with precision. Vague statements like “no previous study has examined this topic” are red flags; they suggest either that you have not searched thoroughly or that you are being dishonest. The gap should be specific: a gap in geography (most studies were conducted in Lagos; yours covers Enugu), a gap in population (existing studies focused on adults; yours focuses on secondary school graduates), a methodological gap (most studies used quantitative methods; yours uses mixed methods), or a conceptual gap (existing studies examined awareness but not behaviour change).
Step-By-Step Process For Writing Your Literature Review
Now that you understand the structure, here is how to actually write it — from scratch, even if you are starting today.
Step One: Clarify your research topic and objectives. Before you search for a single source, re-read your Chapter One. Know exactly what your research questions are. Every source you include in Chapter Two must connect — directly or indirectly — to at least one of your research questions.
Step Two: Conduct a systematic literature search. Use Google Scholar (scholar.google.com) as your starting point. Type your key terms — not your full title, but the core concepts. If your topic is “Effect of NELFUND Student Loans on Academic Performance of Public University Students in Kano State”, your search terms might be: “student loan academic performance Nigeria,” “financial aid university students Africa,” “NELFUND Nigeria higher education.” Save every article that looks relevant, even if you are not sure you will use it.
Also check your university library’s digital resources, ResearchGate, Semantic Scholar, and — particularly for Nigerian policy-related topics — the websites of agencies like the NUC, UBEC, CBN, and relevant ministries.
Step Three: Screen and select your sources. Not everything you find will be usable. Prioritise sources that are recent (published within the last ten years, unless you are citing a foundational theoretical work), peer-reviewed, from credible institutions, and directly relevant to your topic. For most Nigerian final year projects, a minimum of fifteen to twenty solid sources in Chapter Two is expected. Some departments require more.
Step Four: Read critically and take structured notes. Do not read passively. For each source, note: the author(s) and year, the research question they were answering, the methodology they used, the key findings, the limitations they acknowledged, and the gap or question their work leaves open. These notes become the raw material for your synthesis.
Step Five: Group your sources by theme. Before writing, arrange your sources into thematic clusters. Which sources are talking about the same sub-topic? Which ones agree? Which ones contradict each other? This grouping is how you identify your subsections.
Step Six: Write in synthesis, not summary. As you write each subsection, your goal is to weave the sources together into a coherent argument. Bring authors into conversation with each other. Use transitional phrases like: “In contrast to Adeyemi (2021), Okonkwo (2022) argues that…” or “These findings align with earlier work by Ibrahim and Lawal (2019), who similarly observed that…” or “While several studies confirm this pattern (Chukwu, 2020; Bello, 2021; Eze, 2022), the evidence from Northern Nigerian contexts remains sparse.”
Step Seven: Write your gap section last. Once you have reviewed all the literature, you will naturally see what is missing. Write this section after everything else — it should feel like a logical conclusion to the argument you have been building.
Common Mistakes Nigerian Students Make In Chapter Two
Using too many direct quotations. Your literature review should be mostly paraphrased and synthesised in your own words. Direct quotations should be rare and should only appear when the exact wording is critical. Overquoting signals that you did not truly understand what you read.
Citing sources you never actually read. This is more common than supervisors like to admit. A student finds a study cited in another article, copies the reference, and cites it as if they read the original. Supervisors often detect this because the secondary citation context is obvious. Always trace your references to the original source.
Writing “According to [Author] (Year)…” as the first words of every sentence. This is the signature of a literature review written as a summary list. Vary your sentence structure. Not every sentence needs to start with an author’s name.
Using old, irrelevant sources. If your project is on fintech adoption in Nigeria and your most recent citation is from 2013, your review is outdated. The field has changed enormously in a decade. Your supervisor will notice.
Ignoring African and Nigerian scholarship. Many Nigerian students cite only Western authors and journals. While international scholarship is valid, it should not crowd out the growing body of Nigerian and African academic work. Make a deliberate effort to find Nigerian scholars writing on your topic.
Mixing up conceptual, theoretical, and empirical review. Some students dump everything together in one long section. Use clear subheadings to separate your conceptual definitions, your theoretical framework, and your empirical review.
A Word On Plagiarism And Turnitin
Chapter Two is the section most likely to trigger Turnitin flags, because it involves extensive engagement with other people’s work. The way to manage this is not to avoid citing sources — it is to paraphrase properly and cite consistently. Every idea that is not originally yours must be attributed. If you are using APA 7th edition (the most commonly required style in Nigerian universities today), your in-text citation for a paraphrase looks like this: (Adeyemi, 2021), and your full reference appears in your reference list at the end of the project.
Proper paraphrasing means genuinely restating an idea in your own words and sentence structure — not swapping a few synonyms while keeping the original sentence architecture. That is still plagiarism. Genuine paraphrasing requires you to understand the idea well enough to explain it without looking at the original sentence.
What A Strong Literature Review Looks Like: A Checklist
Before you submit Chapter Two to your supervisor, run through this checklist:
- Does my review cover all the key concepts in my research topic?
- Have I identified and explained the theoretical framework guiding my study?
- Have I reviewed a minimum of fifteen to twenty relevant empirical studies?
- Have I synthesised the literature — comparing and contrasting — not just summarised each study separately?
- Do I have recent sources (within the last ten years)?
- Have I included Nigerian and African sources where they exist?
- Have I identified a specific, well-articulated gap in the existing literature?
- Have I used consistent in-text citations throughout?
- Have I avoided excessive direct quotations?
- Does the chapter end with a clear gap statement or summary?
If you can answer yes to every item on that checklist, your Chapter Two is in a position to earn strong marks.
Conclusion
Ngozi eventually rewrote her Chapter Two from scratch. It took her two weeks — much longer than the three days she had initially spent. But when she submitted the new draft, her supervisor read it in silence for several minutes, looked up, and said: “Now this is a literature review.” She passed her defence without a single major correction to Chapter Two.
The difference was not that she found different sources. She used many of the same articles. The difference was that she finally understood what she was building — not a list, but an argument. Not a museum of other people’s ideas, but a foundation for her own.
As the Igbo proverb says: Onye wetara oji wetara ndụ — he who brings kola brings life. Every scholar who wrote before you brought something to the table. Your literature review is how you honour that contribution, learn from it, build on it, and then find the space at that table that only your study can fill.
If you are a final year student working on your project right now, take this seriously. Chapter Two is not just an academic requirement — it is the moment you prove that you belong in the scholarly conversation. Read widely, engage critically, synthesise boldly, and write with confidence.
