anything centered around lecturing or professor-class interaction. when I'm paying attention and I hear something, I remember it. in most of my college classes, I didn't even bother taking notes; I just listed to what the professor was saying, understood it, and remembered it.
I had a couple professors who really favored small group learning. ie: they'd break the class up into 4-5 person groups, for the groups to discuss the material, and the prof would just chill in the front of the class grading papers. I hated that.
