Instructions: Searching and appraising literature
When conducting a literature review, what are the steps you should you take to successfully search the evidence? Once you have generated your results, how do you properly appraise the evidence, grade them, and select the ones you want to use?
When conducting a literature review, the goal is to produce a set of results that match your search criteria. The results you get will vary dramatically depending on the search engine(s) you utilize and which key words you choose to enter. Selecting the right database(s) is one skill; selecting the best key words is another. In this Assignment, you will hone your skills in both of these important aspects of the search process.
Keep in mind, the results of your search will vary in terms of quality, as well as appropriateness, and significance to your research goals. For this reason, searching is only the first step of the process. The second step is to appraise the results you identified, and based on your evaluations, select the literature that you will select.
