Mika LaVaque-Manty, LSA - Political Science, began experimenting with lecture podcasts in 2006. He mainly uses podcasts in his large introductory courses, although he has used them at the 400-level, as well. He uses Profcast, a college-licensed, shareware application for the Mac. Profcast requires no additional equipment beyond a laptop because it resides on the same machine as the lecture presentation. It captures both the presentation slides--whether PowerPoint or Keynote--and syncs them with the audio. Professor LaVaque-Manty twice created a podcast-only lecture when he had to cancel the live lecture.
