My professor wants me to find articles from peer-reviewed journals. What does that mean?
An article that comes from a peer-reviewed journal has been evaluated by other scholars and experts in the field prior to being published. They make sure that the article contains quality, relevant information that is valuable to their field, and they may request that changes be made before the article can be published. Sometimes the database you are searching (Ex: Academic Search Premier) will tell you if a journal is peer-reviewed. You can also check that journal's web site or contact the library if you are having trouble determining if something is peer-reviewed.
