VoiceThread is a collaborative, multimedia slide show that holds images, documents, and videos and allows people to navigate pages and leave comments. VoiceThread is typically used as a presentation tool.
The Online Learning Team maintains two guides for this tool, which are available on Canvas via the iSchool Online Learning Support site. You can access the first guide, which provides an overview of the software, here. You can access the second guide, which discusses integration of VoiceThread with Canvas, here.
