With VoiceThread, group conversations are collected and shared in one place from anywhere in the world. All with no software to install.
A VoiceThread is a collaborative, multimedia slide show that holdsimages, documents, and videos and allows people to navigate pages and leave comments in 5 ways - using voice (with a mic or telephone), text, audio file, or video (via a webcam). Share a VoiceThread with friends, students, and colleagues for them to record comments too.
Users can doodle while commenting, use multiple identities, and pick which comments are shown through moderation. VoiceThreads can even be embedded to show and receive comments on other websites and exported to MP3 players or DVDs to play as archival movies.
You need to register but it doesn't take that much time, but you do need to play with this program extensively before you let your students on it, because it can do quite a lot, as you can see above, and you need to teach this one, not just let the students play on it.
