VoiceThread is a collaborative multimedia presentation tool that allows users to upload images, documents, and videos and then leave comments via voice, text, audio, or video. Users can navigate slides, doodle on them, use multiple identities, and control which comments are visible. VoiceThreads can be embedded on websites and exported to playbacks. It can be used in the classroom to demonstrate student knowledge through assessments, for collaborative research, and interactive lessons. VoiceThread promotes higher-level thinking, interaction, communication, and technological literacy skills in a motivating way.
