1. Sweden, yes!
In Sweden’s Preschools, Boys Learn to Dance and Girls Learn to Yell – New York Times 24.03.2018
Science may still be divided over whether gender differences are rooted in biology or culture, but many of Sweden’s government-funded preschools are doing what they can to deconstruct them. State curriculum urges teachers and principals to embrace their role as social engineers, requiring them to “counteract traditional gender roles and gender patterns.”
It is normal, in many Swedish preschools, for teachers to avoid referring to their students’ gender — instead of “boys and girls,” they say “friends,” or call children by name.[…]
Exactly how this teaching method affects children is still unclear.
One of the few peer-reviewed efforts to examine the method’s effects, published last year in the Journal of Experimental Child Psychology, concluded that some behaviors do go away when students attend what the study called “gender-neutral” preschools.
For instance, the children at these schools do not show a strong preference for playmates of the same gender, and are less likely to make assumptions based on stereotypes. Yet, the scientists found no difference at all in the children’s tendency to notice gender, suggesting that may be under a genetic influence.
