[edit] Uses in the Classroom

With the amount and variety of podcasts that are out there this isn't a limit to the content that is available, but only a limit on content. For example if you are teaching language there is a wide range of content related to learning languages everything from Mandarin to Spanish. So what could you use this for? Well if you have been listening to the podcast for a while and you know that the content is related to your subject you simply might want to clue students into it. Those white buds in their ears may not just be listening to the latest album. You could use this in class if it related to an activity that you have planned.

One great example is the MAKE magazine podcast which covers all sorts of science type projects. Basically if you wanted to have students learn about everything from hover crafts to biospheres the 3 to 5 minute videos give a wealth of information and are done in a fun and humorous way. So perhaps downloading this videos and PDFs that relate to your science classroom and giving the students hands on opportunities to explore a concept would benefit a variety of students. You could also extend the project by taking and submitting photos to Flickr related to individual projects.

The best way to begin is to subscribe to a few podcasts and listen along or watch what is of interest to you.
