Single-Sex Schools 'Bad for Boys' Men educated in all-male schools likelier to divorce By Rob Quinn, Newser Staff Posted Dec 1, 2009 3:29 AM CST 22 comments Comments Boys make their way to classes across the historic cobbled School Yard of Eton College in Eton, England.

The British study, which tracked 17,000 adults who had attended a wide range of single-sex institutions, found no corresponding increase in marriage breakdown amid women who gone to all-girl schools. The study backs up other research showing that single-sex schools are good for girls but bad for boys, the head of a teachers' association tells the Independent. "Girls seem to learn what the nature of the beast is if they have been to single sex-schools whereas boys taught on their own seem to find girls more puzzling," she said. "Boys learn better when they are with girls and they actually learn to get on better."
