How did your workshop go on technology? I appologize for not getting back to you. I had computer issues for a couple of months and decided to upgrade. If you still need information, please let me know.
Judi, below I listed a video I just made you on JING and shared via screencast.com. It is from one of my previous wiki spaces I created for my English 12 Honors class 2 years ago. I can make more videos of my different wikis if you would like. Hope this helps!
With your work in Education Technology, I recommend you take a look at Wiziq's virtual classroom and authorstream's power point presentation platform. Both are web based platforms, have a bunch of features and free basic service.
