Podcasting is a growing trend in higher education. Major software companies, such as Apple, have dedicated entire websites to podcasting. These podcasts are available to college students to be used as supplemental material for specific coursework at their particular college or university. Unfortunately, due to the new and progressive nature of the technology, empirical studies of the effectiveness of this pedagogical device are rare. This paper presents an empirical study of the effectiveness of podcasting when incorporated as supplemental course material in a university course.
