I teach 3-credit 100-level and 300-level courses, half on-line and half in lecture. My students are always complaining of too much homework. I suspect they are just poor students. They never want to answer how much time they spent on the work. All of the work is so easy for me, if I tried to do a week's homework myself, it would take 30 minutes, but this seems a poor measure. How can I measure if the work is genuinely too much?
