Interestingly, some of the question you are required to find can be elusive. This can make it difficult to assess the effectiveness of the study being reviewed and how to determine its usefulness in future research. Although highly dependent on the writing style of the researcher and the publishing requirements of the journal, current research has a 3-4 consistent parts. The abstract is meant to be a brief description of the study and findings which allows the reader to determine if they want to read further. Below are the standard parts.
Introduction/Purpose: Usually provides background information on the issue and why it is a significant research problem.
Method: This should give you the research design and how it was used. It should also provide some rationale as to why the particular method was selected and how the researcher ensures that the data/instrument is valid and reliable. Reliability has to do with the data collected and validity has to do with the manner or instrument of collection. You can not have reliable data without a valid collection instrument, although you can have a valid collection instrument without reliable data. A quick example would be a study that requires an item to be weighed on a scale. Validity would be the taring/resetting of the scale as well testing it for accuracy. Reliability would be more about the presence or absence of bias in the sample. This is the area that a lot of your assignment is based on.
Results: This section is where the collected data is presented.
Conclusion/Discussion: This area is where the significance of the findings are analyzed and future research topics suggested.
