Writing a literature review is an essential part of providing a critical evaluation of existing data from existing studies. It is a way to identify potential areas of research to explore and draw new conclusions from existing data. When writing a literature review, it is important to establish the writer's point of view and explain the criteria that will be used to analyze and compare the literature. Additionally, it is necessary to indicate why certain literature is included or excluded (scope).
The first step in writing a literature review is to determine the purpose of the review. This will help guide the structure and organization of the review. It is important to consider the scope of the review, as this will determine which studies are included or excluded. Once the purpose and scope of the review have been established, it is important to identify relevant sources.
This can be done by searching databases such as Google Scholar, PubMed, and Web of Science. It is also important to consider other sources such as books, journals, and conference proceedings. Once relevant sources have been identified, it is important to read and analyze them. This involves critically evaluating each source and determining its relevance to the topic.
It is also important to consider how each source relates to other sources in order to draw conclusions about the topic. Finally, it is important to organize and present the findings in a clear and concise manner. This can be done by summarizing each source and discussing how they relate to each other. It is also important to consider any gaps in the literature and suggest possible areas for future research. Writing a literature review can be a challenging task, but with careful planning and research it can be an effective way to identify potential areas of research and draw new conclusions from existing data.
