Here is a visual tour of CrowdGrader, from creating an assignment, to submitting homework, reviewing and discussing it, and assigning final grades. The tour lets you see CrowdGrader at work both from the perspective of a teacher and from that of a student.
Note that we constantly roll out improvements to CrowdGrader, so at times the pages you can see here may be slightly out of date.
Why not see how it works for yourself? Just go to CrowdGrader, or create a demo assignment!
