From the VoiceThread website:
"With VoiceThread, group conversations are collected and shared in one place from anywhere in the world. All with no software to install. A VoiceThread is a collaborative, multimedia slide show that holds images, documents, and videos and allows people to navigate pages and leave comments in 5 ways - using voice (with a mic or telephone), text, audio file, or video (via a webcam). Share a VoiceThread with friends, students, and colleagues for them to record comments too."
Prof. Alexandra Pickett at SUNY Albany has a nice example of using VoiceThread where students in an online class post their introductions. See:
Go to VoiceThread at http://voicethread.com/ and register for your FREE account.
After you have registered, then go to the following URL:
and post a message in a reply to the text on each of the two slides. Just so that you are prepared, the two slides have the following questions:
Slide 1: Who are you? Introduce yourself to the workshop participants.
Slide 2: Expectations. What one thing are you most interested in learning in this workshop?
Note that you can post your messages in VoiceThread in a number of different ways - with a web cam (audio and video), with a microphone on your PC (audio only), or by typing text. Simply click on the "Comment" button associated with each slide. Click on the large arrows in the lower right and lower left corners of the VoiceThread window to navigate through the slides.
To take full advantage of this powerful web-based environment, you should post audio (or audio and video) if at all possible.
