No, really, I want to know.
I know what I think the purpose should be, but I'm pretty sure that the current system is some sort of purposeless monster stumbling around like a headless chicken while we argue about whether to bring it back to life with electricity, clockwork or good old-fashioned black magic.
(Okay, that was a little grotesque.) It's just that I've become pretty convinced that we can't fix anything until we can agree as a society on what we want our public education system to achieve.
What do you think is our purpose? (Multiple purposes are acceptable, I suppose.)
