Any teacher can fill a bookshelf with books about education. Any teacher can study lists of guidelines, standards, principles, and theories. The best teachers and the worst teachers can ace exams in their undergraduate and graduate classes. The difference between more effective teachers and their less effective colleagues is not what they know. It is what they do. This course is about what great teachers do that sets them apart. Clarifying what the best educators do, and then practicing it ourselves, can move us into their ranks.
