For many of us, learning to teach in a different way is a long and not always easy journey. Old habits die hard. Moreover, most of us are not particularly well-prepared to confront the task. We have copious amounts of content knowledge but lack great storehouses of information on teaching or learning. Most of us haven't read a lot about teaching and learning and aren't particularly well-versed in relevant research findings. We don't always know what we should do, but we do know we aren't happy with the way things are.
