A growing number of educators in the United States have begun to question just how beneficial computers are in the classroom. The debate raging in the United States is being closely watched by European and Asian educators who welcome technology but also want to learn from American mistakes. Statistics shows that 26 percent of American schoolchildren aged 5 to 9 years old use computers at school. Yet little research has been conducted to examine what impact computers have on children’s cognitive and emotional development. Our concern is that this is very powerful technology, the effects of which we don’t really know.
