Perhaps a tangent, but Waldorf education is the polar opposite of an open school system. It does emphasize the whole human, giving a lot of time to various arts, but the program is curriculum oriented and teacher driven. It's also quite rigorous; having formed the basis of my education, transferring into public high school was a shock.
It's also closely connected to an odd but harmless religious sect, which is a tangent on a tangent.
