    Recently a group of second-graders visited our school library to work on a "holidays around the world" project. The children created pictures showing holiday customs and then created voice recordings explaining what they drew. The incident showed very clearly the effectiveness of student-created voice recordings. Now imagine taking things one step further and creating Podcasts in a classroom setting.
    The term Podcast(播客)refers to an audio recording, linked to the Web, that can be downloaded to a personal MP3 player. The word is created from broadcast and from iPod—the wildly popular MP3 player from Apple.
    Using audio with students isn’t new, of course. Teachers have used audiobooks at listening centers and recorded student voice on tape or CD. Voice and music are the original media for teaching. Podcasts, however, can reach a much wider audience in a time frame outside the school days. Booktalking, an old way of getting kids excited about books, gets a tech assistance with Podcasting. Students can do some booktalking themselves; book review Podcasts seem to be another natural way for students to share what they know, providing an alternative to the book report.
    There are a number of excellent reasons for using Podcasting. Teachers made audio Podcasts, including visuals or video clips for any content area instruction and review. Some teachers have begun to record themselves teaching important concepts; this creates an account of information online for kids to access when they’re stuck on a homework assignment. Audio and video files can also function as assessment tools. Imagine being a classroom teacher in September who can actually hear how his or her students were reading in June the school year before.
    You don’t need an iPod to make a Podcast. If you have a computer, a microphone, and some free software, you can make a Podcast.
