A peer review discussion enables students to provide feedback on another student's reply to a class discussion. Peer reviews are a tool that allows communication between students and can help students master the concepts of a course and learn from each other.
Peer reviews can only be added as part of a graded discussion. Unlike peer review assignments, discussions cannot be assigned anonymously.
Also unlike assignments, discussions do not allow students to complete peer reviews for students in other groups. When you require peer reviews for a group discussion, students can only complete peer reviews for discussion replies made by other students in their group.
