alt Hacker NewsHumans are not so different from one other that we need different ways. However there are a lot of ways that work and it is very hard to run a real study to figure out which is best. You cannot isolate all the variables (several of the different ways claim teacher quality is important - just one variable that is hard to isolate)
Why do you think? For an example of something in support of my argument, China (and a number of other East Asian countries) use a very hardcore memorization + training routine. And they are having literally the best educational outcomes in the world from it, but such a thing would almost certainly fail catastrophically in a contemporary American classroom.
