As a former school board member, I love this post. You provided a lot of insight as to the plight of great teachers. I wonder what you think about the idea of a uniform national math curriculum (with multiple tracks). It seems to me that this would reduce the burden by providing lesson plans for teachers, and it could be paired with online support for students. I also think that math would be the best subject to try this, because there should be less regional variation compared with other subjects.
