This tag is specifically for questions relating to students evaluating the work of other students. The evaluations can be given to either or both of the instructor or the student being evaluated. It is often used for evaluating teammates on a joint project, but can be used for mor general situations.
Use this tag for all questions related to students giving evaluation of one another's work.
Simple uses of peer evaluation involve exchanging of papers with comments made by each party. More involved is evaluation of the work of teammates on a joint project. The need for peer evaluation may arise when students work outside the view of an instructor, for example.
Peer evaluation may feed into the overall evaluation of each student or may not.
Note that this tag is not for questions relating to students working together or helping one another in general. Such evaluation may help the one evaluated improve in a future cycle, of course.
