I think it is a great idea for students to be able to use the rubric to self-assess themselves before they submit to their instructor for grading. As learned in this module, it teaches them the importance of "owning" of their individual learning/work.  While I think more advanced online students would be willing and thrilled with the opportunity to do this, some students, no matter how many times or ways they are advised in and how to improve, still do not take advantage of the suggestions, or even additional attempts allowed for improvement. Yet, the ones who do, are always very appreciative of the suggestions on how to improve, and that they can re-submit for an improved score.
