And do a final exam on oen and paper and nothing else, and an exam that relies more on thinking than rote memorization of formulas (or print the relevant parts of the course on the exam document itself).
there probably is no time for 100 students to each do that in a university mathematics lecture, but there are probably ways to make sure students are still learning by restructuring the university into mandatory recitation and labs or something
