How convincing are the results? Are any of the results surprising?What does this study contribute toward answering the original question?

Underline key sentences or write the key point  of each paragraph in the margin. Although the abstract can help you to identify the main points, you cannot rely on it exclusively, because it contains very condensed information.
Remember to focus on the parts of the article that are most relevant.
Read for depth, read interactively. After you have highlighted the main points, read each
section several times. As you read, ask yourself these questions:
• How does the design of the study address the research questions?
• How convincing are the results? Are any of the results surprising?
• What does this study contribute toward answering the original question?
• What aspects of the original question remain unanswered?
