Podcasting involves creating audio or video files that are distributed over the Internet using RSS feeds. Users can subscribe to podcasts using aggregator software like iTunes to be notified when new episodes are posted, which they can then listen to or watch on computers or portable devices. There are many uses for podcasting in education, such as teachers recording lessons for students, students creating podcasts to share learning, and administrators using podcasts for professional development. Creating effective podcasts involves planning content, recording audio or video, editing the files, and posting the finished product along with an RSS feed for users to subscribe to and access new episodes.
