You have to teach them the appropriate use of a computer, it really is that simple. I have three kids, 2,8,10. All know how to use a computer. Yeah the 2 year old knows how to put her Elmo CD in the drive and click to start the program, so I call that using a computer.

Anyway, computers are a tool. You need to teach kids just that. As important as a pencil, or a slide-rule, compass, etc. When the time comes they will use those too.

To exclude children from computers because they might use it to cheat is, for all intents and purposes, ludicrous.

I'm sorry you had that experience with your child but try to keep it in perspective.
