This is a screen shot taken from a Camtasia movie of Elluminate VCS fron their website: http://www.elluminate.com/Products/Elluminate_VCS/?id=74/
The shot on the left shows 4 people having a live session from home on what the website calls “low-end broadband.” Specifically, the video says that each participant is sending 162-200 kilobits of data per second (kb/s) and that they are receiving a total of 700 kb/s in order to see all 4 participants on their screen. This is not a high bandwitch requirement.
The right-hand screen-shot shows 2 people in a virtual class sessions collaborating on an xls file.
Elluminate or WebEx can be used a a virtual classroom solution where the focus is not on facial cues but on the resources and/or media to be dicussed. Also useful when there are a large group present on the main campus and students coming in remotely fromm one or more campuses. They contribute in real time to the session and can ask questions either by voice or by chat and can see the class as a webcam is focused on the class as well as the lecturer. The session is recorded and available for those students who have been unable to attend and for review at a later date. Students are allocated to real or virtual classes by location and visible on calendar
