Types of Literature Reviews Most often associated with academic-oriented literature, such as a thesis, dissertation or peer-reviewed journal article, a literature review usually precedes the methodology and results section. Literature reviews are also common in a research proposal or prospectus (the document that is approved before a student formally begins a dissertation or thesis). Its main goals are to situate the current study within the body of literature and to provide context for the particular reader. Literature reviews are a staple for research in nearly every academic field. A systematic review is a literature review focused on a research question, trying to identify, appraise, select and synthesize all high quality research evidence and arguments relevant to that question. A meta analysis is typically a systematic review using statistical methods to effectively combine the data used on all selected studies to produce a more reliable result. Distinguishing between Process and Product Shields and Rangarajan (2013) distinguish between the process of reviewing the literature and a finished work or product known as a literature review.[3] The process of reviewing the literature is often ongoing and informs many aspects of the empirical research project. All of the latest literature should inform a research project. Scholars need to be scanning the literature long after a formal literature review product appears to be completed. A careful literature review is usually 15 to 30 pages and could be longer. The process of reviewing the literature requires different kinds of activities and ways of thinking.[4] Shields and Rangarajan (2013) and Granello (2001) link the activities of doing a literature review with Benjamin Bloom’s revised taxonomy of the cognitive domain (Ways of thinking - Remembering, Understanding, Applying, Analyzing, Evaluating and Creating). The first category in Blooms taxonomy is remembering. For a person doing a literature review this would include tasks such as recognition, retrieval and recollection of the relevant literature. During this stage relevant books, articles, monograms, dissertations, etc. are identified and read. Bloom’s second category understanding occurs as the scholar comprehends the material they have collected and read. This step is critical because no one can write clearly about something they do not understand. Understanding may be challenging because the literature could introduce the scholar to new terminology, conceptual framework and methodology. Comprehension (particularly for new scholars) is often improved by taking careful notes. In Bloom’s third category applying the scholar is able to make connections between the literature and his or her larger research project. This is particularly true if the literature review is to be a chapter in a future empirical study. The literature review begins to inform the research question, and methodological approaches. When scholars analyze (fourth category in Blooms taxonomy) they are able to separate material into parts and figure out how the parts fit together. Analysis of the literature allows the scholar to develop frameworks for analysis and the ability to see the big picture and know how details from the literature fit within the big picture. Analysis facilitates the development of an outline (list). The books, articles and monographs read will be of different quality and value. When scholars use Bloom’s fifth category evaluating they are able to see the strengths and weaknesses of the theories, arguments, methodology and findings of the literature they have collected and read.[8] When scholars engage in creating the final category in Blooms taxonomy, they bring creativity to the process of doing a literature review. In other words, they draw new and original insights from the literature. They may be able to find a fresh and original research question, identify a heretofore, unknown gap in the literature or make surprising connections. By understanding how ways of thinking connect to tasks of a literature review, a scholar is able to be self-reflective and bring metacognition to the process of reviewing the literature. Most of these tasks and thinking challenges occur before the writing even begins. The process of reviewing the literature and writing a literature review can be complicated and lengthy. It is helpful to bring a system of organization and planning to the task. When an orderly system can be designed, it is easier to keep track of the articles, books, materials read, notes, outlines and drafts.
