Podcasting allows audio and video files to be distributed over the Internet for playback on devices like computers and MP3 players. Podcasts can be downloaded using a podcast client like iTunes which checks RSS feeds for new episodes. Podcasts are easy to create and listen to, and provide educational benefits like improving students' writing, speaking, collaboration and research skills. Teachers can use podcasts to record lectures, distribute homework help and information, and students can create their own podcasts.
