Hi Guest Lecturers!
Please take a look at David's latest brilliant discovery: Voicethread.
Here is a link to his first crack at it in his Writing 390 class:http://polaris.umuc.edu/ewc/voicethread/vt_report1.html
Let's think about and discuss what ways this tool might help us in guest lecturing. Perhaps we could use one whole thread for questions using Voicethread. David might be able to create a specific thread to post in 999 we could use for each guest lecture that offers this for students.
I would love to hear your thoughts on this.
