Here's a link to an interesting article on how schools are using Elluminate vRoom for distance learning: http://www.thejournal.com/articles/21222
The article points out that distance learning has been around awhile, but typically schools invest in dedicated rooms with videoconferencing equipment, speakers, microphones, etc. or in portable videoconferencing equipment. In my opinion, a solution like Elluminate is better because with very little additional hardware (a webcam and/or microphone) students and teachers can participate in a variety of online field trips, webinars, meetings, and collaborative projects, whether it's in a computer lab, or at one workstation, with or without a webcam, with no additional software to purchase. Sessions can be recorded and replayed later for review, or for absent students.
We are using a new electronic gradebook in our county this fall. I'm hoping I can use my Elluminate vRoom to have several webinars with teachers at their convenience without either of us having to drive. And because I can share or remotely control applications, the sessions can still be interactive.
Now all I have to do is figure out how to roll out this "paradigm shift" in PD.
