I plan on having the children do book talks using audacity. A book talk is an oral book report. I know the children would  have a lot of fun sharing books they have read and listening to other book talks. 

There's a feedback problem in the demo, which would be solved by having students use headsets and microphones when listening and recording their own pronunciation.  I could not use one when making the screencast because the listener would not be able to hear the original audacity recording.
