Writing a dissertation literature review requires a clear understanding of its key components and the distinctions between a literature review and a literature survey. Additionally, we will address common misconceptions about literature reviews in this section.

Definition and Key Components of a Literature Review

A literature review is a comprehensive examination and analysis of existing scholarly research and publications on a particular topic or research question. It involves systematically reviewing, summarizing, and synthesizing relevant sources to provide a comprehensive overview of the current state of knowledge in the field.

Key components of a literature review include:

  1. Research Objective and Scope: Clearly define the purpose of your literature review and establish the boundaries of your research. This helps you focus on specific research questions or themes and avoid getting overwhelmed by the vast amount of literature available.
  2. Information Sources: Identify the appropriate sources for your literature review. These may include academic journals, books, conference proceedings, dissertations, and reputable online databases. It is essential to ensure the credibility and relevance of the sources you choose.
  3. Search Strategy: Develop a systematic search strategy to locate relevant literature. This involves using appropriate keywords, Boolean operators, and advanced search techniques to access the most pertinent articles and publications. Organize your search process and document your search terms for future reference.
  4. Critical Evaluation: Thoroughly evaluate the quality and relevance of each source. Consider the author’s credentials, methodology, key findings, and the overall significance of the research. Critically analyzing the literature helps you identify gaps, contradictions, and areas where further research is needed.
  5. Synthesis and Organization: Once you have analyzed multiple sources, synthesize the information to present a coherent and logical narrative. Group related studies, identify key themes or concepts, and present them in a structured manner. This allows readers to follow the logical progression of ideas.

Differentiating Between Literature Review and Literature Survey

Understanding the distinction between a literature review and a literature survey is crucial. While these terms are sometimes used interchangeably, they have different emphases and objectives.

A literature review focuses on critically analyzing existing research to identify key findings, gaps, and areas of controversy. It synthesizes and evaluates the literature to provide a comprehensive overview of the current state of knowledge.

On the other hand, a literature survey typically involves a broader exploration of existing literature without a detailed analysis. It aims to identify and catalogue relevant sources without necessarily delving deeply into their content. A literature survey is often a preliminary step in the research process and helps researchers become familiar with the existing literature on a particular topic.

Common Misconceptions About Literature Reviews

There are a few common misconceptions about literature reviews that are important to address:

  1. Literature reviews are mere summaries: While literature reviews involve summarizing existing research, they go beyond simple summarization. A literature review requires critical analysis, evaluation, and synthesis of multiple sources to understand the topic comprehensively.
  2. Literature reviews have a fixed structure: While there are common elements and guidelines for structuring a literature review, it is not a rigidly standardized format. The structure may vary depending on the specific requirements of your discipline and the nature of your research.
  3. Literature reviews only include published research: While published research is an integral part of a literature review, it is not the sole source of information. Including relevant unpublished works, conference papers, and dissertations can provide valuable insights and perspectives.

How to Write an Effective Dissertation Literature Review: Preparing for the Literature Review

Proper preparation is essential before diving into writing a literature review for your dissertation. This section will guide you through the steps of preparing for the literature review process, including identifying the research question or topic, conducting preliminary research, defining inclusion and exclusion criteria, and developing a systematic search strategy.

Identifying the Research Question or Topic

The first step in preparing for your literature review is clearly defining your research question or topic. Having a well-defined focus will help you narrow down your search and ensure that you select relevant sources. Consider the specific aspect of your research that you want to explore and formulate a concise research question that aligns with your dissertation objectives.

Conducting Preliminary Research and Creating a Research Plan

Once you have identified your research question or topic, it’s time to conduct preliminary research. Start by exploring general sources, such as textbooks, encyclopedias, and reputable websites, to gain a broad understanding of the subject area. This initial exploration will help you familiarize yourself with key concepts, terminology, and debates surrounding your topic.

Create a research plan as you gather information during the preliminary research phase. Outline the key themes, subtopics, or aspects of your research question that you want to explore in-depth. This plan will serve as a roadmap for your literature review and help you stay focused as you delve into more specific sources.

Defining Inclusion and Exclusion Criteria for Selecting Sources

Defining clear inclusion and exclusion criteria is crucial for selecting sources that align with the objectives of your literature review. Consider factors such as publication date, geographical relevance, language, research methodology, and relevance to your research question. This step ensures that you include high-quality and up-to-date sources while filtering out irrelevant or outdated ones.

By setting specific criteria, you can streamline your search process and maintain consistency in the selection of sources. However, it’s important to remain open to unexpected and valuable sources that may not perfectly fit your criteria but provide unique insights.

Developing a Systematic Search Strategy

A systematic search strategy is essential to ensure that you capture all relevant literature for your review. Start by identifying the appropriate databases, libraries, and online platforms that house scholarly articles, books, and other relevant publications in your field. Some commonly used databases include PubMed, JSTOR, Scopus, and Google Scholar.

Crafting effective search queries is a crucial aspect of your search strategy. Utilize keywords, Boolean operators (such as “AND,” “OR,” and “NOT”), and advanced search techniques to refine your search results. Experiment with different combinations of keywords and use quotation marks to search for exact phrases.

How to Write an Effective Dissertation Literature Review: Searching and Evaluating Sources

The process of searching for and evaluating sources is a crucial step in conducting a comprehensive literature review. In this section, we will discuss how to identify relevant databases and sources, conduct effective keyword searches, evaluate the credibility and relevance of sources, and organize and manage references using citation management tools.

Identifying Relevant Databases and Sources

To begin your search for relevant literature, it’s essential to identify the appropriate databases and sources in your field. Some commonly used databases include:

  1. Academic Databases: These databases, such as PubMed, JSTOR, and Scopus, provide access to a wide range of scholarly articles, conference papers, and other research publications.
  2. Subject-Specific Databases: Specialised databases may focus on specific subject areas depending on your research topic or discipline. For example, Engineering Village for engineering-related research or PsycINFO for psychology-related research.
  3. Library Catalogs: Your college or university library may have an online catalogue that allows you to search for books, theses, dissertations, and other print resources.

Additionally, consider other sources such as government publications, industry reports, reputable websites, and conference proceedings that may provide valuable insights into your research topic.

Conducting Effective Keyword Searches

Keyword searches are a vital aspect of conducting an efficient literature review. Start by brainstorming a list of relevant keywords and phrases related to your research question or topic. Consider synonyms, alternate spellings, and related terms to ensure comprehensive results.

When conducting keyword searches, keep the following tips in mind:

  1. Boolean Operators: Use operators such as “AND,” “OR,” and “NOT” to refine your search. For example, “climate change AND adaptation” will retrieve articles that include both keywords, while “climate change OR global warming” will retrieve articles that include either keyword.
  2. Truncation and Wildcards: Utilize truncation symbols (such as “” or “$”) or wildcards (such as “?” or “#”) to capture variations of a word. For instance, searching for “teach” will retrieve results containing “teach,” “teacher,” or “teaching.”
  3. Phrase Searching: Use quotation marks to search for exact phrases. For example, searching for “renewable energy” will retrieve results that contain the phrase rather than individual occurrences of the words.

Experiment with different combinations of keywords and search strategies to refine your results and capture the most relevant literature.

Evaluating the Credibility and Relevance of Sources

When conducting a literature review, it’s crucial to critically evaluate each source’s credibility and relevance. Consider the following factors:

  1. Author Credentials: Assess the authors’ expertise, qualifications, and affiliations. Check their institutional affiliations, previous publications, and reputation within the field.
  2. Publication Venue: Consider the credibility and reputation of the journal, conference, or publisher. Is it well-regarded in your field? Is it peer-reviewed? Assessing the publication venue helps determine the reliability and rigour of the research.
  3. Citation Analysis: Explore how often other scholars have cited the source. High citation counts can indicate the influence and significance of the research.
  4. Research Methods: Evaluate the methodology and study design employed by the authors. Assess the reliability, validity, and appropriateness of the methods used.
  5. Relevance: Determine if the source directly addresses your research question or contributes to the broader context of your literature review.

Organizing and Managing References Using Citation Management Tools

As you gather sources for your literature review, it’s essential to organize and manage your references efficiently. Citation management tools, such as EndNote, Zotero, or Mendeley, can assist in organizing your references, creating bibliographies, and generating citations in various citation styles.

These tools allow you to import references from databases, organize them into folders or categories, add notes and tags for easy retrieval, and automatically generate citations and bibliographies in your desired format.

How to Write an Effective Dissertation Literature Review: Analyzing and Synthesizing Literature

The analysis and synthesis of the gathered literature form the core of a well-crafted literature review. This section will explore the steps involved in analyzing and synthesizing the literature, including developing a coding system or thematic framework, extracting key information and data, summarizing and categorizing findings, and identifying gaps and controversies in the existing literature.

Developing a Coding System or Thematic Framework

To effectively analyze and synthesize the literature, developing a coding system or thematic framework is helpful. This involves identifying key themes, concepts, or categories that emerge from the literature and organizing them in a systematic manner. Consider using software tools like spreadsheets or qualitative data analysis software to assist in this process.

Creating a coding system or thematic framework establishes a structure for organizing and categorizing the information extracted from the sources. This allows for a comprehensive analysis and facilitates the identification of patterns, relationships, and trends in the literature.

Extracting Key Information and Data from Selected Sources

Once you have developed a coding system or thematic framework, you can begin extracting key information and data from the selected sources. This involves carefully reading and analyzing each source and identifying relevant details such as research findings, methodologies, sample sizes, theoretical frameworks, and key arguments.

Ensure that you extract information consistently and systematically, aligning it with the established coding system or thematic framework. Take comprehensive notes and document the source details for accurate referencing later on.

Summarizing and Categorizing Findings

As you extract critical information from the sources, it is essential to summarize and categorize the findings based on the identified themes or categories. This step involves condensing the information into concise summaries that capture each source’s main points and arguments.

Summarize the findings to highlight the relationships, similarities, and differences between different sources. This synthesis of information helps you build a coherent narrative and present a comprehensive overview of the existing literature on your research topic.

Identifying Gaps and Controversies in the Existing Literature

An important aspect of analyzing and synthesizing literature is identifying gaps and controversies in the existing body of knowledge. By critically examining the sources and comparing the findings, arguments, and methodologies, you can uncover areas where further research is needed or where conflicting viewpoints exist.

Identifying these gaps and controversies allows you to position your own research within the broader scholarly discourse. It provides opportunities for you to contribute new insights, address unanswered questions, or propose alternative perspectives in your dissertation.

Provide a brief overview of the current state of knowledge in the field and highlight the gaps or controversies that your research aims to address.

Presenting the Main Themes and Subtopics

In the main body of your literature review, present the main themes and subtopics that emerged from your analysis. Each theme or category should have its own subsection where you summarize the relevant literature, highlighting fundamental studies, theories, and arguments. Ensure to integrate the findings from various sources to demonstrate a comprehensive understanding of the topic.

Discussing and Analyzing the Findings

When discussing and analyzing the findings, critically evaluate the literature. Identify the strengths and weaknesses of different studies, methodologies, or theories, and discuss any inconsistencies or contradictions you encountered. Present a balanced perspective by discussing both supporting and opposing viewpoints and highlighting any emerging trends or patterns in the literature.

Incorporating Critical Evaluation and Synthesis

Throughout the literature review, it is vital to critically evaluate the sources and synthesize the information in a meaningful way. Avoid simply summarizing each source individually, but rather analyze and synthesize the findings, identifying common themes, gaps, or areas of contention. Provide your own insights and interpretations supported by the evidence from the literature.

Providing a Clear and Logical Flow of Ideas

Maintaining a clear and logical flow of ideas is essential in a literature review. Ensure your paragraphs and sections are organized coherently, with clear topic transitions. Use topic sentences and headings to guide the reader through the review and help them navigate the different themes and subtopics. Consider using linking words and phrases to create smooth transitions between sentences and paragraphs.
