"At Imperial College London, medical students navigate a full-service hospital where they see patients, order X-rays, consult with colleagues and make diagnoses. An avatar approaches a virtual patient in a hospital inside the online world Second Life.
It’s an interactive, hands-on learning experience — and none of it is real.
These prospective doctors are treating virtual patients in Second Life, the Internet world where users interact through online alter egos called avatars. The third-year med students are taking part in a pilot program for game-based learning, which educators believe can be a stimulating change from lectures and textbooks."
