I'm sorry, but I don't agree.
The one main difference, for example, between my education and that of boys at similar type of school was that we were expected to do Domestic Science, and they did Woodwork.
There will always be differences between boys and girls - because there are sexed differences - but the way that gender has become packaged up now has resulted in many girs wanted to simply opt out of what 'being a girl' is now supposed to represent.
My granddaughter ( who is now 8) decided she wanted her cut short when she was 5 ( in spite of no other girls at her school having short hair). She's quite athletic and sporty and likes gaming/tech amongst other more 'girly' preferences. The stylist my daughter had booked completely freaked out. She'd never cut a girl's hair short before - so another older, more experienced stylist had to take over. This is quite common now, I notice: some women's stylists just don't/can't work with short hair. There is a uniform, standard look amongst many girls now -which involves long, straight hair, fake tan, nails etc
I used to teach in secondary schools - and I simply don't think it is true that the gulf between girls and boys was any wider when I was at secondary school - than it is now. It maybe because I went to an school geared up to academic accomplishment? Personally I think single sex schools are good for girls - they can just focus on what they enjoy and are good at without the distraction of boys/pubertal surges etc
I don't think that much has changed between men and women, actually- the hard wired differences ( and same issues) remain - even though more women are now in a range of occupations they simply wouldn't have been in the 1970s.
