Feedback is essential in a student's learning process. It's hard to decipher if written self assessment-feedback is helpful. A rubric definitely informs the student of what is expected of their work, and what the instructor is expecting for the final product. I have found that written peer review feedback is not always helpful. Most of the time, I have reviewed students giving others in their group all exceptional contributions, when you know that one or more students do most of the work. Not sure how to get around that problem.
