I agree and as a mum of twin boys I find it quite worrying.
I'm an ex teacher and think the system is definitely more geared up for girls but I think there are exceptions with both sexes.
One of my twin boys is very "girly" so to speak-loves reading,writing,playing the piano,sitting down to work etc.He hates sport,football etc.He's always loved school,fits right in etc.His twin is just the same re intelligence but the complete opposite ie loves the outdoors,racing around,loathes writing etc.Seeing him have to sit down and put pencil to paper is torture at times but now he is 8 it's getting better.
The studious twin is pushed,streets ahead at school and he shouldn't be imvho. What seriously pisses me off is said "girly" twin gets better marks for science,history etc than the other twin purely imvho because he has neat tidy writing,is studious etc.My rough and tumble boy knows masses more,he's a fact addict but because he's left handed,untidy and sits dreaming of the outdoors and his inventions at home,hates writing so doesn't write as much he gets lower marks,doesn't get pushed,gets bored and so it goes on. Having said all that he's doing ok so not a lot I can do I guess.I also think his time will come when he's matured,doing subjects he enjoys etc.
I think there should be more outdoorsy activities across the curriculum,less sitting down in the early days,more hands on practical stuff less obsession with neat writing and presentation.You can develop fine motor skills in soooo many ways.I have a dd who is a combination of the 2. Due to having brothers she's a tomboy at times so would suit a more practical curriculum too.
Due to restraints in space,housing etc kids are cooped up for too long.They need the outdoors,freedom to shout,run,climb etc.Girls need this too but boys more so and I think they're suffering.They're cooped up at home,stuck in front of gadgets to stop them crawling up the walls then restrained far too much at school.
On a social aspect I'm appalled by the attitude of smogs,not mums with both sexes but smogs. There is one particular girl at school who has basically bullied my studious son because as she keeps telling him she doesn't like boys and boys are rubbish.My dp had to go into complain as he had a rough time at playtime with her not letting him play with the girls and also being a bully in the classroom.Sorry but said charmer gets that from somewhere ie home.You see it in parks everywhere.The intake of breath from girl mums as boys race around, the boys are too rough,loud whine etc.I'm fed up with hearing the "I'm sooo glad I've only got girls" thing you hear constantly.It's rude and a put down.
Another worry is how boys are portrayed in literature. That was in the media recently. Several experts are worried about the "Hermione factor" ie girls are often now portrayed as superior to boys in literature and boys are portrayed as dumb and slower.Not got time to link but it was out there on the BBC site not long ago and an interesting read.
All in all as a mum of 2 boys I worry.
