This approach helps highlight ethical issues which you should be aware of and consider as you go through your own study.Systematic Review This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyze data from the studies that are included in the review.
Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse.
However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].
The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.
Methodological Review A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis].
The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Should I provide subheadings and other background information, such as definitions and/or a history?
Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections.For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text.Some disciplines require that you use information that is as current as possible." This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.Theoretical Review The purpose of this form is to examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena.Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies.Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally that become part of the lore of field.The goal is to deliberately document, critically evaluate, and .Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?A good strategy is to begin by searching the HOMER catalog for books about the topic and review the table of contents for chapters that focuses on specific issues.You can also review the indexes of books to find references to specific issues that can serve as the focus of your research.
