More computers at home hinder learning?

Some German researchers studied a sample of 175,000 15 years old students in 31 countries and discovered that too much exposure to computers may actually affect the developing mind.
Research shows that ability in maths and reading had suffered significantly among students who have more than one computer at home. And while students seemed to benefit from limited use of computers at school, those who used them several times per week at school saw their academic performance decline significantly as well.
“You could argue that’s the big issue here: People need guidance in how to use [computers in education],” says Dr. Marcia Linn, professor of education and director of the Technology Enhanced Learning in Science Center at the University of California at Berkeley.
The people here will refer to not only teachers but parents as well. Many of our current parents have grown up and learnt in the no-internet era. So it seems that there are still some gaps to be closed in our education before computers will bring less ‘side-effects’.
