Podcasting involves creating audio files and distributing them through RSS feeds for playback on devices like computers and iPods. Teachers can use podcasting to record classroom lectures, vocabulary words, and foreign language pronunciations for students to access whenever they want. Creating a podcast requires a microphone, recording software like Audacity, and hosting space on a website or blog to upload the finished audio files. Sample classroom projects include having students make podcasts giving tours of local points of interest, recording chapters of stories they write, or creating how-to guides.
