Many instructors require you to use peer-reviewed sources for your papers and projects, but what does that mean?
Most databases allow you to limit your search to peer-reviewed articles
Cooper, J. O., Heron, T. E., & Heward, W. L. (2007). Applied Behavior Analysis. Columbus, OH: Merrill.
Behavior Analysis Certification Board Task List (Content Area T) http://www.bacb.com/index.php?page=100248
Supplementary readings available through the course website, from the instructor, or located by students themselves through UNT libraries (campus and on-line).
A fast way of determining if the article you are viewing is Peer Reviewed or Scholarly, is to search for the title of the journal which published the article in: Ulrichsweb
The Referee Shirt icon indicates the journal is refereed or peer reviewed.
