When I was a kid, we used to copy stuff out of the encyclopedia. Today they are copying out of a news site. Projects need to be structured in a more interactive way that bypasses this strategy. Also make sure that homework is done. A lot of parents find it useful to make computer time interaction time with their kids, to discuss what they're seeing online and help structure their time that way.
Some kids become computer-addicted.
And the parents then both need to act forcefully and also think about what the child may be avoiding or solving by spending so much time with the computer. For children, I think it means spending a lot after school hours on the computer, neglecting school work, neglecting social and family relationships, becoming very upset when computer use is restricted, and losing interest in other things. I've worked with kids who have spent 20 to 30 hours a week online, who have stayed up through the night chatting, and I think this is a serious problem. The computer can become a battleground between parents and the child, and I've seen parents take away keyboards, disconnect phones, take away plugs, in an effort to control use. Sometimes the solution is to move the computer into the living room, and prevent the child from being alone in the room with it, because for some children, it's use is addictive.
