“the mechanism is that the student works all the problems they can and then asks in office hours or review session about the problems they couldn’t do”
Wait, really? You want all 150 students in all your classes to come to your office every time you give out a homework assignment?
I never went to office hours unless there was some kind of highly unusual situation going on, like when I had a migraine with aura during an exam and couldn’t read the questions. Or when my wife had a life threatening accident and I had to tend to her and needed an extension on an assignment. Were other students just going in and out of there constantly?
