FWIW the teachers lack perspective. I've dated several teachers and listened to their side about why they teach the way they do. I would propose simple solutions, like a continuous improvement cycle, and educational experiments conducted at random by regular teachers, then reproduced and cross referenced to build new models. They had never considered these ideas before.

When you live your life in a rigorously controlled institution, you only consider what the institution echos. Outside the box thinking is possible, but it's the exception. You need outsider ideas and collaboration.

Politics will never solve these problems. It has to be grassroots and volunteer driven.
