As the Internet becomes the more and more popular, some students can't help play online games or chatting. It was not only a problem of wasting time, but also a seriously problem which does harm to their health. Which teachers should do first is to find out what makes them addicting to computer games. Lack of love from his parents? Poor test scores? Parents can have a heart-to-heart talk with them. Secondly, teacher should help them build up their confidence but make them interested in studies. Thirdly, find something else for them to do instead playing computer games.
