What Should Be Included In A Dissertation Literature Review

Writing a dissertation is a monumental task that requires extensive research, critical analysis, and coherent organization of ideas. Among the various sections of a dissertation, the literature review stands out as a critical component. It serves as the foundation upon which the entire dissertation is built, providing context, theoretical framework, and justification for the research conducted.

A dissertation literature review should encompass several key elements to ensure its effectiveness and relevance to the research topic:

Comprehensive Coverage: The literature review should cover a wide range of relevant sources including academic journals, books, conference proceedings, and other scholarly publications. It should demonstrate a thorough understanding of the existing literature related to the research topic.

Critical Evaluation: Merely summarizing existing literature is not sufficient. A successful literature review critically evaluates the strengths and weaknesses of each source, identifies gaps in the existing research, and highlights areas where further investigation is needed.

Synthesis of Findings: The literature review should not be a series of disjointed summaries. Instead, it should synthesize key findings from various sources, identify common themes or trends, and present a coherent narrative that guides the reader through the existing literature.

Theoretical Framework: A strong literature review establishes the theoretical framework for the research. It should discuss relevant theories, concepts, and models that inform the research questions and hypotheses being investigated.

Methodological Approach: Depending on the research methodology employed, the literature review should discuss relevant methodological approaches used in previous studies. This includes research design, data collection methods, and data analysis techniques.

Relevance to the Research Question: Every aspect of the literature review should directly contribute to addressing the research question or problem statement. Irrelevant or tangential literature should be omitted to maintain focus and clarity.

Citation and Referencing: Proper citation and referencing are essential in a dissertation literature review. All sources cited should be accurately referenced according to the appropriate citation style (e.g., APA, MLA, Chicago).

Given the complexity and rigor involved in writing a dissertation literature review, many students find themselves overwhelmed by the daunting task. It requires not only a deep understanding of the subject matter but also advanced research and writing skills.
