changes for schooling K-12

There are many things I can think of for possible change in the K-12 schooling. Yet at the same time I feel as if there is no general big fix that can be applied to see changes take place. I think that the educational system has spun itself into a circle that keeps feeding the negatives. In a system failure like this, I believe it would be better to start from the bottom. Build a new foundation and work our way back up. If you don't fix a lot of the core issues, we could essentially make small changes, end up seeing progress, but then the issue would most likely come back. Building a foundation on our educational system that starts with the bottom would allow us to build up, try new concepts without fear of losing years in a children's education. For example, if we tried a new way of learning in a fourth grade classroom with a secure foundation, even if the new way of learning wasn't received as well as we would have the foundational educational backing to still provide the fourth graders with a proper program. There are a few changes that would need to be set up prior for this concept to even work.
