No facts about it, just some random assertion. Schools aren't going to change the way males relate to playing games, sports, and farting around in general compared with actually studying.
What other part of the article did I miss? Oh, this:
> the education system isn’t doing very well by lots of our boys and men now. We have a ten percentage point drop in the share of male teachers, incredible underinvestment in apprenticeships and vocational forms of learning, and all kinds of changes in school environments that mean that we’re not serving them very well.
What changes in environments? Vocational means simply that boys don't do desks and paper well- is that true? Do male teachers make that much difference? The thrust here is that the economy has left men behind. Maybe that's true, which is more important.
You would be surprised. A boy having a male mentor is extremely helpful. Oftentimes an adult male can connect with boys in ways that an adult female might have trouble with. Teachers, for better or worse, are mentors. They are who kids spend the most time around during school semesters, and where they receive the most instruction, outside of parents.
Now don't get me wrong. Boys can absolutely succeed without a male teacher in their lives, and it's great that we have lots of female teachers. But it is absolutely helpful for a boy to have a man to look up to in some fashion.
This article makes a lot of good points about it, though its more about mentorship in general instead of male mentorship:

Sounds like you have already thought about this and came to a sexist conclusion.
lets flip this around. lets say we live in an alternative universe where primary school is primarily male dominated. just drawing from your own life experience, would you ask if not having female teachers affects female students?
