I have an assignment for class participation in a course I am currently assembling. The assignment is worth 100 points. I would like 50 of those points to be determined by student peer reviews based on a rubric I have designed. However, since students don't actually submit a paper to be reviewed, I just want them to consider each others' contributions, I am not sure how to proceed. I have set the assignment up as a peer review assignment, but I don't know whether this will work with just a rubric and no assignment submission. Help gratefully received!
