But that Japanese experience is not just created by the teachers, the other students and their parents are a very big part of it. I think kids around that age care most about their peers. If they didn't do as everybody else there they would really stand out negatively.

Otherwise, the problem could be solved by importing Japanese teachers to American schools, in person or just their training. I would be surprised if just exchanging for other teachers had a huge impact. That would mean it has always been the teachers fault, which I highly doubt.
