Its job is to show your committee three things: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>that you understand the theories relevant to your topic, <\/li>\n\n\n\n<li>that you know what has already been studied empirically, and <\/li>\n\n\n\n<li>that you can identify exactly what still needs to be studied \u2014 which becomes the justification for your research.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Done well, Chapter 2 does more than summarise other people&#8217;s work. It builds the case for your study. Everything you write in Chapter 1 about the &#8220;gap in knowledge&#8221; has to be backed up here, with evidence.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Before You Write: How to Search and Organise Literature<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most guides skip straight to &#8220;review the theories&#8221; without addressing the part students actually get stuck on first: finding and managing the literature itself.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Where to search:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Google Scholar (free, broad coverage \u2014 start here)<\/li>\n\n\n\n<li>Your university library&#8217;s subscription databases (JSTOR, ScienceDirect, EBSCOhost, ProQuest)<\/li>\n\n\n\n<li>Subject-specific databases (PubMed for health sciences, IEEE Xplore for engineering, EconLit for economics)<\/li>\n\n\n\n<li>Grey literature sources (government reports, NGO publications, working papers) when your topic needs current, real-world data that hasn&#8217;t been published in peer-reviewed journals yet<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Also read:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/resourcefulscholarshub.com\/where-to-find-journal-articles-for-phd-research\/\" data-type=\"post\" data-id=\"557\">Where to Find Journal Articles for PhD Research (7 Best Sources)<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How to search effectively:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use Boolean operators: &#8220;maternal health&#8221; AND &#8220;postpartum&#8221; AND Kenya<\/li>\n\n\n\n<li>Search using your key variables, not your whole topic sentence<\/li>\n\n\n\n<li>Check the reference lists of 2\u20133 recent, highly-cited papers in your area \u2014 this &#8220;snowballing&#8221; technique often surfaces sources faster than a fresh search<\/li>\n\n\n\n<li>Set a cut-off: aim for the most recent 5\u201310 years of literature, with a few older foundational or seminal works included for theory<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Also read:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/resourcefulscholarshub.com\/boolean-operators-and-modifiers-effective-search-strategies\/\" data-type=\"post\" data-id=\"559\">Boolean Operators and Modifiers: Effective Search Strategies for PhD Students<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Tools to manage what you find:<\/strong> <\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use a reference manager from day one \u2014 retrofitting citations later is one of the most time-consuming mistakes PhD students make.

It tells the reader what the chapter will cover and, briefly, how it is organised \u2014 for example, whether you&#8217;ll move from theoretical review to empirical review to conceptual framework, in that order.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Theoretical Review<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The theoretical review follows the chapter introduction. Here, you review the theories behind the topic under investigation. For each relevant theory, cover:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Who developed the theory, and when<\/li>\n\n\n\n<li>The theory&#8217;s main arguments or propositions<\/li>\n\n\n\n<li>How the theory has previously been applied to study your problem, or similar problems<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Most topics are explained by more than one theory. Review all the theories that are relevant, then do a short comparative analysis \u2014 how do they differ, where do they overlap, which one has the most explanatory power for your specific problem? End the section by naming the theory (or theories) that will underpin your study, with a clear justification for that choice. This becomes your <strong>theoretical framework<\/strong>, and examiners will ask you to defend it, so don&#8217;t skip the justification.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Empirical Review<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After the theoretical review, you review empirical studies related to your problem. Empirical literature refers to original studies \u2014 ones based on actual data collection and analysis \u2014 as opposed to purely theoretical papers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is the section that separates a strong literature review from a weak one, because it requires critique, not summary. Avoid writing sentence after sentence of &#8220;Author A (2022) found X. Author B (2023) found Y.&#8221; Instead, engage with the studies:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What did each study find, and how strong is the evidence?<\/li>\n\n\n\n<li>Where do studies agree? Where do they contradict each other \u2014 and why?<\/li>\n\n\n\n<li>If two studies on the same topic reach different conclusions, examine <em>why<\/em>: different populations, different methodologies, different contexts, different sample sizes?<\/li>\n\n\n\n<li>What are the limitations of the existing studies, and how does that create room for your research?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A useful habit: after reading each source, write one sentence answering &#8220;So what does this mean for my study?&#8221; before moving to the next one. That sentence is often the seed of your critique.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Chronological vs. Thematic Organisation of Empirical Literature<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are two common ways to organise your empirical review.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Chronological Organisation<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Literature is organised by date of publication, oldest to most recent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Advantage:<\/strong> shows how understanding of the problem has evolved over time. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Disadvantage:<\/strong> the discussion can feel disjointed, since similar studies get separated simply because they were published years apart.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Thematic Organisation<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Literature is grouped by theme or variable rather than by date. Each variable in your study gets its own subsection, where all the studies that examined it are discussed together \u2014 highlighting where they agree and where they disagree.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Advantage:<\/strong> creates a smoother, more analytical flow, and makes it much easier to spot research gaps within each theme.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While the choice varies by institution, <strong>thematic organisation is generally preferred at PhD level<\/strong>, because it demonstrates synthesis rather than just a summary of individual papers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Using a Literature Synthesis Matrix<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before you start writing full paragraphs, build a simple synthesis matrix \u2014 a table with one row per study and columns for: author\/year, purpose, theory used, methodology, key findings, and limitations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This does two things:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>First, it forces you to extract the information you actually need rather than re-reading full papers when you sit down to write. <\/li>\n\n\n\n<li>Second, once the matrix is filled in, patterns jump out visually \u2014 you can literally see where studies cluster (a well-covered theme) and where rows are thin or contradictory (a potential gap). <\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Many students find this single step cuts their writing time in half, because the analytical work happens <em>before<\/em> the writing, not during it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Not sure how to create the literature synthesis matrix?

This is especially important for quantitative studies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Building the conceptual framework involves three steps:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Identifying all the variables<\/strong> that will be analysed in your study (independent, dependent, and any moderating or mediating variables).<\/li>\n\n\n\n<li><strong>Specifying the relationships<\/strong> between those variables, based on what the literature review revealed.<\/li>\n\n\n\n<li><strong>Drawing the diagram<\/strong> \u2014 typically boxes for variables, ovals for constructs, and arrows showing the direction of the hypothesised relationships.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">A simple example: if your study examines how <em>access to prenatal care<\/em> (independent variable) affects <em>postpartum depression rates<\/em> (dependent variable), with <em>social support<\/em> as a moderating variable, your diagram would show an arrow from access to prenatal care to postpartum depression, with social support positioned to show its moderating effect on that relationship. Keep the diagram as simple as the relationships require \u2014 resist the urge to add variables just because a paper mentioned them if they are not central to your study.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Identifying Research Gaps<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The core purpose of the literature review is to document what is known \u2014 and what is not. Research gaps are the &#8220;not yet known&#8221; part, and your contribution to knowledge comes from addressing one of them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is why the literature review should genuinely come before you finalise your topic, not after: reviewing existing work first, then settling on your specific angle, produces a much stronger justification than picking a topic and searching for gaps to fit it retroactively.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are three broad types of research gaps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Conceptual gaps<\/strong> \u2014 a variable or angle that hasn&#8217;t been studied. <em>Example: most maternal health studies focus on pregnancy and delivery, but not the postpartum period.<\/em><\/li>\n\n\n\n<li><strong>Scope gaps<\/strong> \u2014 differences in coverage:\n<ul class=\"wp-block-list\">\n<li><em>Geographical:<\/em> rural vs. urban, or one country\/region vs. another<\/li>\n\n\n\n<li><em>Time:<\/em> older studies vs. current conditions<\/li>\n\n\n\n<li><em>Demographic:<\/em> different age groups, income levels, or genders<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Methodological gaps<\/strong> \u2014 differences in how the topic has been studied:\n<ul class=\"wp-block-list\">\n<li><em>Design:<\/em> quantitative vs. qualitative vs. mixed methods<\/li>\n\n\n\n<li><em>Data collection:<\/em> surveys vs. interviews and focus group discussions<\/li>\n\n\n\n<li><em>Analysis technique:<\/em> descriptive vs. inferential statistics<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Naming the specific <em>type<\/em> of gap your study addresses \u2014 rather than vaguely stating &#8220;a gap exists&#8221; \u2014 is one of the fastest ways to strengthen your justification in the eyes of an examiner.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Download our research gap finder worksheet that will help you identify your own research gap. <\/em><\/p>\n\n\n\n<div class=\"wp-block-file\"><a id=\"wp-block-file--media-306dc005-31d9-4c84-ae73-641485465cc9\" href=\"https:\/\/resourcefulscholarshub.com\/wp-content\/uploads\/2021\/04\/research-gap-finder-worksheet.docx\">research-gap-finder-worksheet<\/a><a href=\"https:\/\/resourcefulscholarshub.com\/wp-content\/uploads\/2021\/04\/research-gap-finder-worksheet.docx\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-306dc005-31d9-4c84-ae73-641485465cc9\">Download<\/a><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How Long Should the Literature Review Chapter Be?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There&#8217;s no universal rule, since requirements vary by institution and discipline, but as a general guide, Chapter 2 is typically the longest chapter in a proposal \u2014 often 30\u201345% of the total proposal length. What matters far more than page count is density: a shorter, tightly synthesised review that clearly builds toward your research gap will always outscore a longer one that reads like a list of summaries. Check your own department&#8217;s handbook for any specific page or word requirements before finalising.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Chapter Summary<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Close the chapter with a short section summarising what it covered and restating, in a sentence or two, the main research gap your study will address. This sets up a natural bridge into Chapter 3, where you explain your methodology for addressing that gap.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Common Mistakes to Avoid in the Literature Review Chapter<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Summarising instead of synthesising.<\/strong> Restating what each study found, one after another, without comparing or critiquing them.<\/li>\n\n\n\n<li><strong>No visible link to Chapter 1.<\/strong> The gap you identify here must be the same gap referenced in your problem statement \u2014 examiners check for this consistency.<\/li>\n\n\n\n<li><strong>Outdated sources.<\/strong> Relying heavily on literature that is more than 10 years old, with no recent studies to show the field has moved.<\/li>\n\n\n\n<li><strong>A conceptual framework with no basis in the review.<\/strong> Every variable and relationship in your diagram should be traceable back to something discussed earlier in the chapter.<\/li>\n\n\n\n<li><strong>Vague gap statements.<\/strong> &#8220;Few studies have been done on this&#8221; is not a research gap \u2014 it needs to specify what kind of gap, and why it matters.<\/li>\n\n\n\n<li><strong>Weak citation management.<\/strong> Missing in-text citations, inconsistent reference formatting, or reference list entries that don&#8217;t match in-text citations. This is one of the easiest things to fix \u2014 and one of the most common reasons proposals get sent back for what feels like a &#8220;small&#8221; reason.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Final Thoughts<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Chapter 2 is often the most daunting part of a PhD thesis proposal \u2014 partly because it&#8217;s substantial, and partly because it directly informs Chapter 1. Writing a strong &#8220;contribution to knowledge&#8221; section in Chapter 1, for instance, is only possible once you have genuinely read and synthesised the literature in Chapter 2. Formats vary between institutions, so always check your department&#8217;s specific guidelines \u2014 but the underlying logic (theory \u2192 evidence \u2192 gap \u2192 your study) holds across almost all of them.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Frequently Asked Questions<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Is the literature review always Chapter 2?<\/strong> In the standard 3-chapter proposal structure (Introduction, Literature Review, Methodology), yes. Some institutions use a 5-chapter full-thesis structure instead, where the literature review may appear later, but the content and logic described here still apply.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Should I include a conceptual framework if my study is qualitative?<\/strong> It&#8217;s less common, but many qualitative studies still benefit from a simpler conceptual or thematic framework showing how key concepts relate. Confirm with your supervisor what&#8217;s expected in your discipline.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How many sources should Chapter 2 include?<\/strong> There&#8217;s no fixed number \u2014 it depends on how established your field is. What matters is that your review is current, relevant, and sufficiently comprehensive that an examiner can see you know the field, not that it hits a specific citation count.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What&#8217;s the difference between a theoretical framework and a conceptual framework?<\/strong> A theoretical framework is the established theory (or theories) you&#8217;re applying to your problem. A conceptual framework is <em>your own<\/em> diagram of the specific variables and relationships in your study, informed by that theory and the empirical literature.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Related posts<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/resourcefulscholarshub.com\/how-to-write-chapter-1-of-phd-thesis-proposal\/\" data-type=\"post\" data-id=\"621\">How to Write Chapter 1 (Introduction) of a PhD Thesis Proposal (Complete Guide + Examples)<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/resourcefulscholarshub.com\/how-to-write-chapter-3-of-phd-thesis-proposal\/\" data-type=\"post\" data-id=\"634\">How to Write the Research Methodology Chapter of a PhD Thesis Proposal (A Detailed Guide)<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/resourcefulscholarshub.com\/ethical-use-generative-ai-academic-research\/\" data-type=\"post\" data-id=\"2204\">Ethical Use of Generative AI in PhD Research: A Practical Guide for Students<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/resourcefulscholarshub.com\/note-taking-tips-for-phd-research\/\" data-type=\"post\" data-id=\"545\">11 Note-Taking Tips for PhD Research That Actually Save You Time<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The second chapter of a PhD thesis proposal in most cases is the literature review.
