Which does rather imply that some of us must be doing something right.
Any tuition is generally better than none at all wouldn't you say? I was reading research the other day supporting the idea that the single biggest indicator of success in life is having ambition. No more, no less. Now tell me, how many teachers do you honestly know that sow that seed in the minds of their students? How many do you honestly know that inspire their students to love their subject as much as they do? To read widely around their subject outside of school as much as possible? To believe that there is so much more out there to learn than what is contained within the crappy exams set by the government?
That's probably the main difference between kids in private schools and kids in state schools. The private ones have it instilled in them that they can be whatever they want to be. Given how rubbish Britain is at social mobility you have to question how effective state schools are at instilling the same lifestyle.
It's not about money. Public libraries are free. The web is as good as free, where you can download learning resources like never before. Heck, many leading universities in America are giving their courseware away online. Money or poverty or whatever isn't a barrier to learning anymore. The only barrier is motivation. That's what teachers should be there to do. They should inspire kids to want to learn. Lets face it, the knowledge kids leave school with isn't going to be enough to get a job doing anything. That's just a fact due to the time constraints involved. In my field of IT you learn bugger all in IT classes at school (and I have checked the curriculum). Certainly not enough to compete against the Indians. So you need kids to both realise that and be motivated enough to do much more on their own time. Forget the exams, they're not important. The knowledge is important, the exams just measure knowledge, they don't provide it.
Maybe I've just got a bad sample, but the schools I've worked in didn't have any teachers like that. The teachers I know now certainly aren't like that. Indeed for the majority of them they'd rather spend money on a holiday somewhere or a new car than on books. So you have to ask yourself, do they love learning or do they love the perks of their job?
Hey, I could be naive, but for me you want teachers with spirit like Keating in Dead Poets, and right now I don't think we have enough like that.
