I thought I should mention the CyberSurgeon sessions. During a live simulation students connect with a chief medical officer via videoconferencing to diagnose and treat researchers and patients aboard a research ship stationed in a Brazilian rain forest. Way cool...
"To complete the mission, students become part of the fictional CyberSurgeons remote trauma unit on a mercy ship. The simulated ship is equipped with a high-tech hospital and medical research capabilities, state-of-the-art high-end communications systems, and dedicated satellites to relay information.
The mission is conducted through a web/ videoconference hookup from your classroom to the Challenger Learning Center at the Center for Educational Technologies at Wheeling Jesuit University in Wheeling, WV."
