Could a different theoretical perspective have been more effective?
Is the theoretical framework evident?
Did the researcher evaluate relevant research to the study topic? Does it include literature that may be in conflict to the study?
In assessing the research study, consider the basic components of the study design (e.g., population, intervention, outcome). How accurate and valid are the measurements? Is the analysis of the data accurate and relevant to the research question? Are the conclusions validly based upon the data and analysis?
In what ways does the research contribute to the field and knowledge of the problem under study? What are the strengths and limitations?
How does the research relate to the specific thesis or question you seek to answer in your own research?
