Scholarly articles read differently than other types of sources. The Anatomy of a Scholarly Article video (3:12 minutes) provides strategies for reading this type of article. And, the Reading Scholarly Articles handout (Word file link) illustrates the structure of a scholarly article. If you decide the article you've found is relevant to your research question, carefully read each section of the article.
Use whatever method works for you. Additional tips:
Print article and highlight or circle while reading
Add notes in the margins of each section
Summarize key/main points
If viewing PDF online, Adobe Reader has features that are helpful such as highlight text and sticky notes
