Hi Mary. I was wondering if you have students or educator contacts who would be interested in participating in a nationwide SAT Vocab Video Contest @ MIT university. You can view contest details at BrainyFlix.com Please let me know. Thanks!
With your interest in Video Conferencing and 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.
