Podcasts, audio recordings published on the Internet and played on computers and portable devices, are becoming popular among all types of audiences, including K-12 teachers and students. Classrooms are both consumers and producers of this technology. As consumers, you’ll find a growing amount of high-quality free educational content for you and your students in podcasts, right at your fingertips! We’ve identified some sources in the resources at the end of this article.
Now it’s easier than ever to make podcasts in the classroom, to become producers. You don’t need a media player, such as the Apple iPod, or specialized software to make or listen to a podcast – just your computer and an Internet connection will do. Though podcasts can be audio and video, audio podcasts will be featured in this article.
LISTENING TO PODCASTS
Podcasts are handy ways to get information – captured on your computer or media player, they are available to you when and where you want to listen. (I catch up on the latest science and education news every day while I bike to work.) And you don’t have to spend time checking the web sites of podcast creators for new episodes. By subscribing to an RSS feed at the web sites of your choice, you will receive new podcasts automatically.
You might listen to podcasts of personal interest, use them as an informal source of professional development, or have your students listen to them (as part of class research on a topic, for example). Of course, not all podcasts are appropriate for students. If you are using iTunes, you can use the Parental Control feature (in Preferences) to prevent students from previewing or downloading podcasts marked with the “explicit” label. But don’t assume that iTunes will do all the work for you! Be sure to listen to the entire podcast before assigning it or using it in class.
SUBSCRIBING TO PODCASTS
In iTunes you can find and subscribe to podcasts in several ways:
- Through the iTunes store. Click on “podcasts” in the left column of the iTunes store, and then “podcast directory” on the lower right-hand corner. You can then “browse” or “power search” to find podcasts.
- Drag the podcast’s RSS icon into iTunes. Most podcast pages display the RSS icon. You can drag that icon into the podcast window in iTunes and the program will subscribe you.
- Type in the URL. In the “Advanced” tab in iTunes menu bar, choose “subscribe to podcast.” Put in the URL for the RSS feed for that particular podcast.
- Click on a “subscribe” link on the podcast’s web site. Many podcasts will have a “subscribe via iTunes” link that will open up iTunes on your computer.
MAKE A CLASS PODCAST
Creating a podcast in the classroom can be a great way to incorporate writing across the curriculum. Narratives like personal stories, drama, history, and music all lend themselves well to audio presentations. Plus, students can be more motivated to create a podcast that could be heard across the world, rather than just within the classroom.
Classroom podcasts will take some time. Start small. Consider divisions of labor for student-created podcasts (writer, editor, voice actor). You will likely have to do the final production of the podcast and help with the equipment. Your students should use stage names and never give any personal information about themselves. Podcasts on web sites are publicly available.
Briefly, here are the main steps in recording and broadcasting a podcast:
- Record the audio using recording software such as Audacity (free!) or Apple Computer’s GarageBand for a Mac. Students can also record via telephone for free at Gcast.com and Gabcast.com.
- Edit using the recording software (Audacity or Garageband) to cut out anything you don’t want.
- Add music and sound effects, make volume fades, and so forth. Free sound effects and samples are available at FindSounds and Sounddogs.
- Compress the audio to an MP3 file. This makes your audio file smaller
- Upload your file to a class web site or other host sites such as Podomatic or Podbean.com The host will make your web page automatically!
Some ideas for class-produced podcasts are:
- Interviews: Students can talk to people who use science in their jobs.
- History:”This day in science history.”
- Podcast drama: A recorded version of a classroom skit.
- Pet podcast: Give kids a chance to talk about biology and nutrition using observations of their pets
- Outdoor observations: Use cell phones or a portable recorder to note observations during urban science walks.
- Where in the World: Submit a podcast to this worldwide geography quiz show – http://www.intelligenic.com/where/
