In Bill Gates' vision of the classrooms of the future, students are grouped according to skill set. One cluster huddles around a computer terminal, playing an educational game or working on a simulator. Another works with a human teacher getting direct instruction, while another gets a digital lesson delivered from their teacher's avatar.
Dianne - Thanks for sharing this. I just recently acquired the Kinect sensor and I am planning to create a classroom use for it. I watched a student use the Kinect at the US Science and Engineering Expo and it looked like a great way to get students involved "in" a lesson.
