Many college classrooms these days may as well have lighted signs over their doors that read "On Air" or "Recording in Progress." A growing number of professors are recording their lectures and making them available as podcasts--regularly updated sets of audio files that students can download to their computers or MP3 players. Some campus administrators have expressed surprise that podcasting lectures--also known as coursecasting--has piqued the interest of so many students and professors. Others note that it's not hard to understand podcasting's appeal. The technology gives professors a chance to meet students on their own turf: After all, students often seem to be joined at the hip, literally, with their iPods. It is easy to imagine students using the devices to make up for lectures they missed, or to brush up on key concepts as final exams approach. The author presents his own six key points advice to college professors who are considering podcasting program of their own. Creating a podcast requires a bit more effort and technical know-how than many professors anticipate.
