Better education, not national service, would have made a big difference to them. Better funding of teachers like KK, smaller class sizes and better school buildings.
I dream about smaller classes. 30 is too many. No-one gets any proper attention. BUT in my school we have a referral unit where damaged children can get 1 to 1 tuition, and I have to say this only slows the process of expelling them. They punch their personal tutors, and refuse to work, they tear up their books and snap their pencils. We have an ex policeman working as a one to one tutor, and I have watched this excellent resource be abused and ignored by those it has been provided for.
There is something more going on here than just a lack of help and resources.
At my school we have at least 30 FREE after school clubs, all non academic - from drama, music, to videoing, editing, break dancing, DJ'ing, every kind of sport. All provided on a voluntary basis by the teachers - not by specially paid after school teachers. The teachers dont get paid extra, they just do it at the end of the day out of their free time.
School is so different to when I went - people may not realise what opportunities there are now for any kid who can be bothered. But the apathy from the kids is so utterly disappointing. They honestly cant be bothered. Most clubs have packed up by the end of Autumn term due to lack of attendance.
