There are clearly biological differences between the sexes when taken as averages; I've always taught children with moderate learning difficulties and it's always been predominantly boys. You get the same answer when you speak to SALT and OTs
In my family it's the girls as well with SEN/ND - though the excuses are different why they can't be helped - tends not to be their sex - but they don't get diagnosed or helped any quicker - and in fact as some conditions are considered male or most people look for male presenatation which isn't helpful.
I get that on average boys may struggle more or more obvioulsy but when that used to avoid giving indivdual boys targeted needed help - I do wonder why that's justified.
But this whole issue is about class. White working class boys - they don't have the parents who'll search out books they'd enjoy, they're not on-line playing
This is what I think as well.
Middle class - immigrant familes keen on education - are protective mechanisms in many way when messages come in from schools/wider societey - they have more social econimic resources to draw on to counter and desire to do so.
When school did trip to creationist zoo - I didn't at first didn't realise - when I did thank to MN I approached the school got reassuarnces they would go to talked mentioning intelligent design. Well they did - so I spent next 18 months watching documentaries, buying and reading age apprppiated children books explaining evolution it - having talk about Darwin at dinner table. Same when they were taught miss information about castles and roman food.
We've done same with reading and maths messaging - counted in a variety of ways - family examples that dispute this - more famous ones many resources.
I do wonder though in this day and age why I am having to do this with such fundamental skills.
