And by the way, the reason why many professors are assigning less homework is not that they suddenly discovered that this strategy is pedagogically beneficial (which it might or might not be depending on a wide variety of factors). It’s simply that enrollment caps have been raised and instructors or graduate students who used to teach different sections of the same course were fired. And now a professor simply doesn’t have time to grade homework in a class that went from 25 to 70 students.
