I am amazed by VoiceThread. I love it! I wish I would have had this tool back in college for all the group work we had to do. I can really see using this tool for so many things. I really like the idea of posting pictures and thoughts for students to comment on, but even more than that, I love the idea of kids commenting on other kids work. Very cool!
This teaches so many things, including constructive criticism. And why not comment on random people's work? Especially kids' work!
