Podcasts can be used effectively in language education by allowing students to share knowledge, form relationships through relevant media, and bring the outside world into the classroom. Teachers can find existing podcasts written for language learners or create their own by planning topics, producing audio recordings, publishing the podcast online with an RSS feed, and promoting it. Popular free software like Audacity allows editing recordings, and blogs provide a home for show notes while services like Blogger or Pod-o-Matic host the audio files and RSS feed.
