1. To provide a clear understanding of the existing knowledge and research on a specific topic: One of the main purposes of a literature review is to review and summarize the existing studies, theories, and concepts related to a particular research topic. This helps the researcher gain a deep understanding and familiarity with the existing body of knowledge on the subject. By examining and synthesizing previous literature, researchers can identify the gaps and limitations in current research, which can guide their own study design and research question formulation.
2. To justify and provide a rationale for the research: A literature review is also conducted to establish the need and significance of the proposed research. By examining prior studies, researchers can identify the gaps or unanswered questions in the literature that their research aims to address. This helps to build a strong rationale for why their research is important and how it contributes to the field.
3. To identify the methodologies, theories, and frameworks used in previous research: A literature review allows researchers to identify the different methodologies, theories, and frameworks used in previous studies. This provides them with valuable insights and potential approaches to consider for their own research. By understanding the strengths and weaknesses of different research methods and frameworks, researchers can make informed decisions about the best approach to undertake in their own study.
4. To establish a context for the research: - A literature review provides a context for the proposed research by situating it within the broader academic discourse. By examining and summarizing the theoretical underpinnings and key concepts discussed in prior studies, researchers can establish a connection between their research and the existing knowledge in the field. This helps readers and reviewers understand how the research fits within the larger academic context and contributes to the overall body of knowledge on the topic.
Overall, a literature review serves as a comprehensive foundation for research by helping researchers gain a better understanding of the existing knowledge, justifying the significance of their research, and providing a context for their study.
