In addition to peer-review assignments, your instructor may wish you to peer reviews discussions. In these discussion assignments, your peers will review your post, including any attachments, and give you feedback on it. You will also review other students’ work and give them feedback on their posts as well. On the discussion index page peer review discussions will display with a peer review icon to left of the assignment icon, as shown below.

In order to complete a peer review discussion, log in and visit the discussion topic page after the due date. Above the discussion description will be a list of students to review, as shown below. Click Review Now next to the student's name to review his/her work. Be sure to consult your course materials for guidelines on how your instructor wishes you to review discussions.
