Absolutely agreed. By the way, a recent sociological study found out that children with access to unmonitored internet chat are less is danger of becoming victims of child predators. Although that sounds strange at first, it it obvious once you consider the fear of real-world child predators that someone might become aware of what they do. The "risk" that children tell their online friends about such predatory behaviour works as a pretty effective deterrent for real-world predators (which are a much bigger group than online predators). I can try to dig up that study if you need it for communication with officials. > > How do we prevent cheating between students? > > You can't prevent this. > > > Like instant messaging each other during quizzes? > > The easiest way would be to have the teacher stand at the back of the > class looking for anyone doing so.

And even if you can prevent that, the kids can use the camera to look back over their shoulder and check whether someone is watching them and cheat by conventional means. Besides that, there's always the possibility of storing a cheat sheet on the laptop itself. Good luck trying to find that. A solution for that is to unpredictably exchange laptops between kids directly before a test, but it runs against the ownership paradigm. Someone with enough time and/or money can always cheat. In many countries, kids have some free time and learning to cheat is probably the topic with the strongest motivation. You can't prevent cheating, but you can make it difficult enough that most kids won't bother.
