They hope computers can help them improve their studies in school, but some children don't do as what parents want them to do. Because they used the computers for surfing on the Internet and spend too much time playing computer games instead of learning. It does not good for their eyesight. So their parents complain about computers not help children to study but also make them fall behind.
