In my own courses, I definitely try to avoid >a situation where students are just expected to "remember facts". I don't know much about the American educational system. But I can imagine where this attitude "remember it and place it on the test" comes from. I teach classes where the aim is to get the candidates to understand a piece of theory. I dare say that I work myself in a sweat to explain things as clear as I can. Problem is that many participants (nowadays) seem to have forgotten what they have been taught the year before. In calculus classes I spend most of my time explaining over and over again "high school stuff" and the fact that many students have been using calculators for a year or two, has caused them to forget the tables of multiplication (well, not all of them, but when a x b equals something over 40 it's really hard for some students). What can you do in such a situation? You are more or less obliged to cover a fixed amount of material, and you get into trouble when too many students flunk. So you demonstrate "how to do the problems", you simplify the exam questions (to the point where the exam consists of reproducing simplified versions of the exercises) and you implore the candidates not to embark on self-invented methods (like providing proofs that are actually isolated examples, or showing that something is impossible by the argument "I can't do it"), but stick to the book. All in the hope that some will pass. JWN
