Make sure your critique includes the name of the article, the authors, and the journal name, volume and pages numbers. Bring copies of your abstract for each student and the instructor. Bring a copy of the article for the instructor as well. See the attached list of suggestions for topics. You are free, however, to choose any subject relevant to class.
Review articles are certainly acceptable.
Have your article approved by the instructor prior to preparing the abstract. Students will receive a zero for any missed exam, if unexcused. Class discussion of topics is strongly encouraged. Also, academic misconduct will be handled according to University policy as outlined in the Student Handbook. These are just a few ideas to get you started.
