We've spent the past few years trying to make freshmen courses more accessible mostly by improving the TA sessions; we spend more time showing examples and trying to encourage students to solve problems within the session over blithely prattling the correct answers to the previous set of home-work exercises. But that's simply shifting the focus of the more hands-on teaching, the kids still have to learn what the fuck it is we're trying to show them, and that explicitly involves having them do it by themselves, no matter how dry or boring it is. I can't make an integral sign blow students no matter how hard I try.
