What I hate are such great blanket headlines like the one at Heise today: Computers can lead to worse grades in school. Of course, poor teaching can also lead to worse grades. Newspapers can also lead to worse grades ...
It gets particularly embarrassing when you read the reasoning:
A computer in the child's room leads in most cases to worse grades in school. This is the conclusion of a study (PDF file) published on Tuesday by the Munich ifo Institute, which specifically evaluated the international data of the PISA studies again. The reason for this: the computer is very often used for computer games instead of being used for learning.
Aha. So let's conclude: playing instead of learning can lead to worse grades. Oh. Oh really. Grandiose insight - and why does the title say something completely different? Maybe the authors played a bit too much and learned too little?
