Leigh Hall of the Education Disruptions blog writes about a project where they are encouraging teachers to collaborate and wondes how best to do this. They have set up a VoiceThread
Although I’ve just sent out one VT, I am hopeful it will work well as a means for communicating information about the project. First, teachers can watch it at their own pace. Second, they can watch it as many times as they want (some of it or all of it). They can also leave comments if they need help with something that others likely could benefit from.
They look at how the voicethreads can be explored further and note how if this had been done as a face-face workshop they would not have the advantage of the recordings being easily available for review
