anyone working on specific classroom/lesson driven virtual worlds? We have been working on bringing a lesson driven virtual world to the classroom interactive whiteboard for the past 12 months - finally making some nice progress - http://edusim3d.com .. still a LONG ways to go !
IMO its a matter of engagement - ( I am sure others see them filling different needs) but for me its more of a way to connect with the student on their turf in a rich 3D environment with lesson driven activities.
