Which is often, to be fair, at least partially the fault of the professor, who structures the course in too much of a jump-straight-to-the-abstraction sort of way. (I include myself in this category---guilty!) I know I've had to learn the hard way just how important it is to take my students through concrete things first and work into the concepts, rather than telling them about a concept (when they're totally unprepared for it) and then expecting them to just do it.

Even now that I'm very aware of the problem, I still relapse when I'm not paying enough attention; and I think a lot of CS professors aren't even aware of the problem.
