This is the issue - are children born or made. I 've always thought it was 50/50.
I remember my children telling me about a boy in their class who didn't dare go home one night as he hadn't got an A in one subject - he was scared of his parents.
We all have, within the law, to achieve our own balance of encouragement and fun at home.
As someone said above the Chinese in England tend to be pretty focussed. The other Asians around me are too particularly ugandan asians whereas the Somalis were penniless and uneducated and tend not to do so well so yes I agree that educational background and aspiration does have an impact on how the chidlren do once they are here.
But China is not that different over there with lots of ours of night school and fierce competition for the right schools.
All interesting stuff. Litc is right that some parents (and sadly some schools) have very low expectations too. Often how well children do is down to that as much as anything else. For example state school children are not less clever than many at private schools so why would children at 10 in sdome private schools be learning very hard choral music in latin in parts and the primary lot being singing wheels on a bus with tamborines? Simply because the teachers and parents are not prepared to put in the effort and there is huge dumbing down.
