I think I could use VoiceThreads this morning as I have completely lost my voice to a winter bug :(
The VoiceThread marketing team created a great diagram explaining what VoiceThread "is not." They call it the proverbial elephant....check it out (roll your mouse over all of the points).
The cool thing about VoiceThread is you can have 1oo's of voices that comment on one of your images. Each voice is represented by a small avatar/image of that person. You can click on each image and hear the message the person left.
It could be a great tool that is used for peer review/collaboration. Students could post their work and other students could comment and critique the work by leaving audio messages (VoiceThreads).
Start with a story concept and use VoiceThreads to build the story....everyone could add a piece....what direction would your story take?
