Podcasting involves creating digital audio files that are published online and can be downloaded to devices like MP3 players. There are two main types - enhanced podcasts which include images and links, and videocasts which combine audio and video. Podcasting allows students to create radio shows, speeches, movies or other classroom projects and make them accessible anytime for learning or review purposes. While portable and inexpensive, podcasts do require audio/video files and uploading can be time-consuming. Creating podcasts involves using microphones, recording/editing software, hosting platforms, and following three basic steps - uploading audio files and RSS feeds, then allowing podcast apps to download the files.
