To my knowledge, this functionality is not available, but I think it should be. If the idea has been broached, my apologies for any duplication.
When I am entering feedback for X in Week 5, I usually want to see what I have said in past weeks. Perhaps I want to remind X of something I said before that he or she may want to review again. Or maybe I just want to avoid saying the same thing in Week 5 that I said in Week 2.
As it is, I have to (a) rely on memory, or (b) go trudging through each past week of the Grade Center, seriatim, looking for what I want.
The idea is this -- a button or feature that permits me to generate a report that includes:
(a) a recital of each assignment to date that the student has completed, and
(b) the feedback that I provided in respect to each respective assignment.
As I said at the outset, if this functionality already exists in the environment, I have utterly missed it.
