Wow, that does sound awful!
I realize you're just getting started, but the devil in me has an idea: perhaps you can try a little self-advocacy and discuss your ideas with the instructor - and then you can share your experiences with your children (and, of course, us!), so they too can learn to ask for work that better suits their needs.
Either that, or you can make your point like my kid does: by chatting with the student next to you, poking people, staring out the window, drooling on your textbook....
