I just got a very polite email from a student requesting the reading assignments for a course.
(It so happens that I'm not teaching the course zie seems to think I am, so that solves that for me.)
Now, if a student emailed me about my Shakespeare class, I could give hir the names of the plays I've ordered. But if I were teaching a survey type course, there's no way I'd know all the stuff I'd ask them to read at this point. And for the course that's brand new for me, other than the books I've ordered, I don't know quite yet.
We have about four weeks to the start of classes, and I think it's pretty reasonable not to have a course calendar planned. How about you?
(I'm not blaming the student for asking, but even if I were teaching hir course, I'd have difficulty answering.)
