I have never, on my own free will, assigned multiple-choice questions in a serious course. And never will. - They have a base marks of 20-25% (by random guessing) instead of 0. - You never see the working. So you can't check if students are thinking correctly. Slightly wrong thinking can get you right answers. - They don't even remotely reflect real life at all. Written worked through problems on the other hand - I still do those in my professional life as a scientist all the time. It's just that I am setting the questions for myself. - The format doesn't allow for extended thought questions. In my undergrad, I had some excellent profs who would set long work through exam question in such a way that you learned something even in the exams. Simply a joy taking those exams that gave a comprehensive walk through of the course. As a prof, I have always tried to replicate that.
