I think I've mentioned it before in the past, though in another context: "The Time Ships", by Stephen Baxter. It's an official sequel to H. G. Wells' "The Time Machine".
The book itself is obviously not about education, but that subject is brought about when the protagonist gets into contact with another species (which I'll not name lest I spoil the book). Basically, the approach to education for that species is that children would be taught how to seek information, and then pretty much just told to go educate themselves, seeking out whatever they want.
Of course that would be utopia for humans, because we are mostly hedonistic by nature, but all the same this idea from that book really stuck with me, and made me realize in which way our educational system is a failure: children are usually just told to memorize stuff, a big part of which they will never really use, when they really should be taught how to "think" - how to seek information, stimulate curiosity and solve problems with information they gather themselves.
Fortunately, with initiatives such as these, it seems as though this is slowly changing.
