Have only read the OP: From my own experience coming to a US high school from high school in Europe, I can only say: of all subjects, math was the most different, in the *way* it was taught. Like a completely 180 degree different approach. In my US high school, we were given a formula, which the teacher quickly explained, and then we were supposed to do hundreds of problems/calculations with it. There was no intrigue, no curiosity, no critical thinking, just using the formula. After days or weeks we received another formula. In my high school in Europe, we never knew where the teacher would lead us, he treated the subject as if we were the first ones to discover the problem and its solution, a lot of math history was involved -just hearing it-. The class arrived at the formula as if we had invented it, we were doing a few problems and moved on. We were several years ahead, content wise. That said, I could not do these calculations anymore, regardless of my US or European approach. Clearly though, I enjoyed the European one infinitely more!
