Experiences with active learning in CS 3

We report on our experiences with transforming CS 3 to an active-learning format. We have now had three separate instructors at our institution begin to integrate active learning into the course. Their approaches to integrating active learning and their experiences with it were quite different. We describe the various approaches of the instructors to the transition, provide synopses of the most effective active-learning exercises that were used, and summarize the lessons learned from these experiences. We expect that this information will be useful to anyone that desires to incorporate active learning into his or her CS 3 or similar course.
