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.    1.    Now imagine taking things one step further and creating Podcasts in a classroom setting.

The term Podcast 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 for many years.    2.    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.

  3.   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.   4.    Imagine being a classroom teacher in September who can actually hear how his or her students were reading in June the school year before.
