Contrarian finding: Computers are a drag on learning: From a sample of 175,000 15-year-old students in 31 countries, researchers at the University of Munich announced in November that performance in math 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.
[T]he German study stands out on account of two features: its unusually broad, international sample and its bid to isolate computers as a performance-shaping factor.
