Here's an interesting article that supports moving away from the lecture method in teaching. Dr. Eric Mazur (Harvard University) advocates using "peer instruction" to get the students thinking and talking about a concept. The key, according to Mazur, is to get the students to read the book chapters or articles before coming to class. The point then of the class time is to make sense of the information they've read by encouraging questions and discussion. He now successfully uses this technique in all his physics classes.
