Assignment

As a follow up to my above comment, the online text assignment is friendlier than a database activity for assignment submission where the online text does not have to be structured, mainly because the submission due date locking mechanism actually works in the assignment activity but not in the database. So I revised the solution such that students submit to online text assignment, but the evaluation is still done in the database. From the evaluation database entry I click a button to open the list of submissions in a popup. In the popup I click on a submission and its data is copied into the evaluation entry. I do the evaluation as above and save. Now I can click on an evaluation item and that will open the grading page of the corresponding submission, paste the feedback, grade and whatever I wish to paste there and that's it.

Again, the current solution is experimental and too rough to be exchanged but I hope the approach may give you some ideas.
