I've been teaching for 20+ years and the degree to which teaching paradigms have changed in the last decade continually amazes me. The old paradigm I learned as a fresh, red-cheeked grad student was that students were like blank sheets of paper, waiting to be filled with a teacher's wisdom/words/ideas/information. Students were passive and much of their knowledge was gained by simply memorizing or repeating information. This was what made a successful student—one who fit into the paradigm, meeting its requirements. I was such a student and so, taught this way.
