Biology teacher Ros Johnson says 3D projections of body organs have given lessons a new direction at the Abbey School in Reading

BBC article, report that “A study of the impact of 3D in the classroom has found that it improves test results by an average of 17%.”

This is a specific example where 3D does make a difference. However, I ask myself what is the advantage of this 3D experience (one 3D projector, and 20-30 of 3D classes) over an alternative simpler one (30 computers running a 3D simulation per students, with no glasses)?

What do you say?
