Employing elements of both radio and blogging, podcasting has enormous potential for providing learning experiences for children. At its most basic level, podcasting involves a person (or team) recording an audio program and saving the program as an MP3 file then uploading the file to the Internet and placing a link to the file in a Weblog. The Weblog includes an RSS feed, and listeners subscribe to the podcast program by adding the RSS feed to their aggregator (iTunes, iPodder, or others), resulting in audio automatically being downloaded into their computers' media players and mobile MP3 players (for example, iPods) as the podcasts are published. Essentially, there's nothing new about podcasting--it's simply another source for compelling content. But it's also a new opportunity to make students better learners by turning them into teachers.
