A literature review is a comprehensive study and interpretation of the literature related to a research topic. The purpose is to provide an overview of relevant theoretical perspectives and previous research findings related to the topic to help identify research gaps that the proposed study will address. Producing an effective literature review requires developing a clear structure and comprehensive search strategy to identify and analyze relevant academic literature.
The structure of a literature review typically follows a specific format to provide organization and flow to the content being reviewed. Most literature reviews contain the following key sections:
Introduction (1500-2000 characters)
The introduction establishes the scope and context of the literature review. It should define key terms related to the research topic and discuss the significance and importance of the topic. The introduction outlines the purpose and structure of the review. It may address the research questions or hypotheses that will be explored.
Theoretical/Conceptual Framework (2000-3000 characters)
This section provides an overview of the theories, models, concepts or perspectives relevant to the research topic. It summarizes how different theorists and researchers have defined and approached the topic conceptually. Key terms are defined and relationships between concepts are explored to lay the foundation for understanding how previous studies have examined the topic.
Methods (1000-2000 characters)
The methods section details the approach taken to locate relevant academic literature. It summarizes the databases and search terms used, inclusion/exclusion criteria applied, and number of studies included. It describes the process of identifying, selecting, and analyzing literature sources. A flow diagram is sometimes included to depict the literature selection process.
Review of Literature (8000-12000 characters)
This forms the substantive core of the literature review. It presents an in-depth analysis and synthesis of previous empirical research studies related to the topic. Studies are grouped thematically based on common findings, perspectives or methodologies. Major findings, strengths/limitations and gaps in the literature are identified. The literature should be evaluated critically rather than described. Diagrams may depict relationships between studies.
Conclusions and Recommendations (2000-4000 characters)
The conclusions section summarizes the major themes, controversies, and insights generated from the literature analysis. It addresses how the review objectives were met. Clear linkages are made between the literature, research questions/hypotheses, and the significance of the study. The recommendations identify gaps in understanding or methods that the proposed study will address, how it will contribute new knowledge, and its implications for theory, research and practice.
References (automaticly generated)
The reference section lists all sources cited in the text in APA citation style. It is formatted alphabetically by author last name. All sources cited must be included regardless of whether a direct quote was used.
Appendices (optional)
Supplementary materials like literature search strategies, tables compiling study details, or visual models are often included in appendices. These provide additional support for the review content without disrupting the flow of the main body.
This outlines a comprehensive structure with sufficient depth and breadth to develop a robust literature review. The exact formatting and length of each section will depend on the topic, scope, and requirements. Adhering to this widely-used structure helps ensure all relevant aspects of the review topic are addressed to inform the research.
