This is my first semester with Moodle 2.4 (was using 2.1 before), and I checked the box for restoring student grades if they re-enrolled, in case they were accidentally removed, etc.
I did not realize that this setting would persist even after doing a course reset.
I now have a student who is re-taking one of my courses (it's the kind of course you can re-take because it's different each time), but he already has grades for all the assignments.
I did a reset again, just of the assignments, before any of them were due. This seemed to blow out his old grades.
However, today, we had our first assignment due, and sure enough, even though his essay file is brand-new from today, it is already showing up as graded, with the grade for this assignment from last semester.
How do I get around this? I'm worried especially about other teachers who may be seeing this behavior, but don't understand it, because I'm the Moodle admin, and only I know about this setting...
I'd like to send out a missive that explains that this may show up, and how to fix it.
I've searched the forums and the documentation, but the only thing I've found about this recommends resetting the course or the assignments, which I'm already done.
