Journal articles articulate how scientists/researchers formulate hypotheses, design empirical studies, analyze the observations they collect, and interpret their results. Journal articles generally follow a standardized format.
Scholarly journals contain articles describing high quality research that has been reviewed by experts in the field prior to publication. This is called Peer Review. Most of the articles you locate in library databases will have gone through this process. However, you will have to apply additional criteria to determine if a specific article is appropriate for your needs and if the research is strong. There are several questions to ask yourself when evaluating journal articles:
Relevance
Authorship
Currency
Article Content
Relationship to Other Articles
