For example, if you are researching the relationship between ecological environments and human populations, provide models and theories that focus on specific aspects of this connection to contextualize your study. Theories and concepts should provide the foundation for your research. A discussion of relevant theories and concepts Because a field is constantly being updated by new work, you can show where your research fits into this context and explain developments and trends in research. The current context of your researchĭiscuss central (or peripheral) questions, issues, and debates in the field. You should also make sure to understand how to paraphrase scientific literature to avoid plagiarism in your work. Providing a historical background also demonstrates to other researchers and journal editors your competency in discussing theoretical concepts. Historical background for your researchĪnalyze what has been written about your field of research to highlight what is new and significant in your study-or how the analysis itself contributes to the understanding of this field, even in a small way. The following are some of the most important elements that a literature review provides. The contents of a literature review (RRL) are determined by many factors, including its precise purpose in the article, the degree of consensus with a given theory or tension between competing theories, the length of the article, the number of previous studies existing in the given field, etc. Rather, you can take the pieces that other researchers have cut out and put them together to build a framework on which to hang your own “books”-that is, your own study methods, results, and conclusions. You don’t need to cut each piece by yourself from scratch. One way to conceive of a literature review is to think about writing it as you would build a bookshelf. Building Your Literature Review Bookshelf Whereas, a standard research article or school assignment literature review section could only be a few paragraphs in the Introduction section. In a dissertation, thesis, or standalone review of literature, it is usually a full chapter of the text (at least 20 pages). The length of a review of the literature depends on its purpose and target readership and can vary significantly in scope and depth. How long is a review of the literature for a research paper? Give the reader an understanding of the background of the field and show which studies are important-and highlight errors in previous studies.Synthesize what has been done in this area of research and by whom, highlight what previous research indicates about a topic, and identify potential gaps and areas of disagreement in the field.Summarize the most relevant and important aspects of the scientific literature related to your area of research.Present a brief typology that orders articles and books into groups to help readers focus on unresolved debates, inconsistencies, tensions, and new questions about a research topic.
