VoiceThread can be used in any academic institution, for any age group, for virtually any purpose. It's a web-based digital-storytelling application that allows users to share their stories through text, audio, images, or videos.
Its site states, "Text alone can't deliver the subtlety and expression required for meaningful connection. If text were enough, we wouldn't use emoticons, get on planes, or use web-conferencing software. VoiceTheading is a more human way to connect."
What all this means is that if you want learners to explain a position, explain their though process, or just interact with others, VoiceThead is a good option. Several instructors have specialized in VoiceThead and depend on it as the backbone of their courses.
It's especially useful in online courses because it is asynchronous and learners can actively participate in "discussions."
