When you want to review a paper, there are several things that you need to look at. Following are some guidelines (not all of them) that you need to do when you are evaluating and summarizing a paper. Please make sure that you follow them in a step by step order. This will make things much easier to read and make your final writing.
1. Make sure that you define what the research question(s) are. This comes in several forms. It could be clearly stated as the research question, hypothesis, problem of study, or topic of study. Simply, answer the question of what the author(s) are studying.
Example: Sumadi (2015) investigates (studies, analyzes, evaluates, etc.) the role of currency devaluation on the balance trade in 1, 2, 3. [You can mention additional investigation topics about the topic]
2. Review the countries under investigation. This must be spilled out clearly. Meaning, you need to state the countries that are studied clearly. Example: The study investigates the trade balance of China with Turkey, Saudi Arabia, and the United States.
3. Determine the duration of the study; what time frame does the study covers. Meaning, what are the years of the study and is it annual, quarterly, or monthly? Example: The study reviews the annual trade data between the countries from 2005 to 2015.
4. Determine what tools did the author(s) use to conduct the analysis. I understand that this could be challenging as most if not all of the methods were not taken during your studies. BUT you only need to mention them and what they test.
Example: The study analyzes the data using Vector Error Correction Model (VECM). They analyze unit root by using … [as you see, you do not need to know the mechanics of the tool used, just know what tool is used … This can be found in the methodology section]
