I have been teaching the same semester course for 2 years, 2 classes per year. I have always copied the previous semester's course with assignments at the start of the new semester. I had always unpublished all assignments and when I used the same assignment, I would change the due date and publish when used. Some of those assignments had even been ones where students submitted work in the past semester, but I went about it the same way.....unpublish, change due date and publish when the time came. When I started this semester, I was not able to change assignments due dates to current dates, unpublish them or delete past assignments. This had never been the case. Even worse, the assignments from last semester's class are seem by students as overdue assignments. Is there anything I can do?
