VoiceThread is best described as an online conversation around media. Whether it’s a conversation around digital pictures, videos or documents, VoiceThread allows conversations to occur in an online space even though the participants might be miles apart. I think the easiest way to get started is to import slides from a Powerpoint and voice over it with any computer that has a built in microphone. It’s really easy to use and free. VoiceThread would be a great tool for having students make presentations in an online class, tell stories or discuss a topic. It’s like a threaded discussion board but has the ability to actually have students’ voices attached to it. Consider posting a paper for a class discussion or a student lesson plan for peer review. VoiceThread even allow users to scribble on the document to highlight parts they’re talking about.
I demonstrated VoiceThread at a Brown Bag presentation recently and showed this VoiceThread example created by a 5th grader in a local school: http://voicethread.com/share/457316/
