Teacher's use of podcasts as a teaching tool!

Hello Everyone!

I wonder if you can help me out?

I am going to be presenting at an ed tech conference next week, discussing my use of teacher created podcasts and screencasts or "masterycasts" and how they have impacted my classroom. I am going to be showing teachers how they can do the same, using their students iPods and mp3 players as teaching tools.

I am looking for other examples to show them! Please share what you have created to help kids, or the work of others you have seen as well. I know I am not the only teacher out there doing this! I am interested in resources and examples running from sites, ITunes (or similar aggregators), or other audio/video use of players of any type assisting learning.

How are educators using audio/video, iPods, and mp3's as teaching and learning tools?

Thanks for your help!
