Too much marking?

For this coming semester, I resolve to provide students with fewer assignments. This is as much for my sanity as for their learning. I suspect that as the number of assignments increase, so, too, does the average student's interest in the assignment decrease, all else being equal. I am seriously considering abandoning the use of project-based learning, as well. [I just found this incomplete unpublished entry from ca. April 2018. Posting it for my memory, as I still have these internal debates. ]
