Part 4A: Critical Appraisal of Research

To Prepare:
• Review the Resources and consider the importance of critically appraising research evidence.
• Reflect on the four peer-reviewed articles you selected in Module 2 and analyzed in Module 3.
• Review and download the Critical Appraisal Tool Worksheet Template provided in the Resources.
The Assignment (Evidence-Based Project)

Part 4A: Critical Appraisal of Research
Conduct a critical appraisal of the four peer-reviewed articles you selected and analyzed by completing the Evaluation Table within the Critical Appraisal Tool Worksheet Template.


Part 4B: Critical Appraisal of Research
Based on your appraisal, in a 1-2-page critical appraisal, suggest a best practice that emerges from the research you reviewed. Briefly explain the best practice, justifying your proposal with APA citations of the research.

**Note on Conceptual Framework

• The following information is from Walden academic guides which helps explain conceptual frameworks and the reasons they are used in research. Here is the link https://academicguides.waldenu.edu/library/conceptualframework

• Researchers create theoretical and conceptual frameworks that include a philosophical and methodological model to help design their work. A formal theory provides context for the outcome of the events conducted in the research. The data collection and analysis are also based on the theoretical and conceptual framework.

• As stated by Grant and Osanloo (2014), “Without a theoretical framework, the structure and vision for a study is unclear, much like a house that cannot be constructed without a blueprint. By contrast, a research plan that contains a theoretical framework allows the dissertation study to be strong and structured with an organized flow from one chapter to the next.”

• Theoretical and conceptual frameworks provide evidence of academic standards and procedure. They also offer an explanation of why the study is pertinent and how the researcher expects to fill the gap in the literature.

• Literature does not always clearly delineate between a theoretical or conceptual framework. With that being said, there are slight differences between the two.
