> I'm not very familiar with the field, unfortunately, but it is my understanding that there is not much of a scientific method applied to teaching theories. As in, not just armchair theorizing, but more like A/B testing. I know, it's a hard problem, but so are many science problems, and Rome doesn't have to be build in one day. But where is the progress? My father's job was to visit primary school teachers to evaluate them, give them advice and organize teacher's continuous education. That was in France, so it's most likely a different system than the US. He regularly bemoaned that education was way too politicised, any new minister of education would try to make their mark by grabbing a new fad with no regards to the scientific validity behind that fad and would ask people like my father to organise classes for primary school teachers who would then be told to follow that fad. This happened for reading methods (luckily the whole language phenomenon known as "méthode globale" didn't last very long in France), the debate on constructivism, etc...
