It is a step in the right direction, but I am not sure it solves the problem. The main problem with the sharing+timestamping approach is that the worksheets continue *available* to the students. So, if a student shares a worksheet and subsequently "touches" it (even, say, opening it by "mistake"), the timestamp changes, and the instructor has no way to know if there were changes made or not.
I don't think opening it will change the timestamp. However, changing something would. I tell my students not to touch their worksheet after the deadline (on penalty of it not being accepted as a "late" worksheet). Then I just download all the worksheets after the deadline (say by the next morning) so I have a fresh copy (and backup) of what was submitted.
This would not be a problem with me now, and I may try this approach with my next lab, since I have a small group that I basically trust. But I don't think it would scale. The definitive solution would be to have a "submit" button that is like "sharing" but instead creates a copy of the worksheet in the "target" account, that can not be accessed by the submitting student.
I agree that there needs to be a "submit to teacher" button of some type that maybe behaves like the publish button (i.e., makes a copy of the worksheet). If someone doesn't get to this, I might work on something like this over the summer, as I'm funded to work on notebook code that makes Sage easier to use in the classroom.
