You can ask a question and have students respond to each other before responding yourself. You can have students work in groups.
Students learn in many different ways, in fact, they can even learn from each other.
This might begin by really paying attention to student evaluations. It might be inviting a colleague to come and see you teach and then listening to what the observer says she or he saw happening - the detailed descriptive kind that focuses on how much and how well they report learning in your course. You might want to dispose of old lecture notes, attend an active learning workshop, and keep your office door open more often. This involves continuing to take personal inventory of your teaching, as well as admitting and correcting errors. It begins with sharing with other lectureholics ways of balancing lecturing with alternative activities.
