I teach an Online class about Online Teaching through a university that has a full Canvas account. In the course I teach student teachers how to use Canvas for Online teaching and they are each required to sign up for a free account and create a sample class of their own during the semester. I have the students add me to their rosters (as a student) so that I can view and grade the work they put into their courses. The problem is I have no way of deleting their free Canvas classes from my dashboard at the end of each semester, and neither can I order them so that the courses being created by my current students come up first. I'm starting to amass too many classes. How can I resolve this problem?
