VoiceThread is a Web 2.0 tool that allows users to post their own thoughts to a picture or video using audio, video, or typed text. Collaborators, or in this case, students, can add remarks to VoiceThreads as well.

VoiceThread can be a very useful tool in the classroom. A teacher could use it to post a picture of something relatable to a school topic, and then add audio comments to explain the picture to their students. Students would the be able to comment on the picture, hopefully sparking intense discussion and debate.
