Assignment

Hi Heather,
I suppose you could use some course reset options. http://docs.moodle.org/en/Reset_course

But there are good reasons not to delete old data and student records. If your course has a start and end date, it might be easier to create a new course at each start date. We use a template from which to create new classrooms (courses) at each of our start dates.

This preserves records and student work without filling up the classroom.
