I went to school like 20 years ago and I spent computing class getting around the security tool, installing Doom 95 and a SNES emulator and then playing multiplayer Street Fighter 2 and Doom 95 with my friends in the class (they both supported LAN play!)

I still went to University and got a Physics degree.

I think the most important thing is that the kids feel that the class is important, I felt computing class (which was basically Microsoft Office class) was a waste of time, so I just played games. But I understood that I had to study a good degree to get a good job. So in Maths, Science etc. I paid complete attention.
