I think the results apply to any culture. Excessive studying doesn't produce the intended results. The trend has also been towards increased homework but it's beginning to wane in more developed areas. I wish I knew how to accelerate the trend because it's continuing to do harm to a generation of kids.
I was not commenting on the results. I was commenting on the person from China's concern that Chinese schools would never agree. This is true. American schools do not have to any degree whatsoever the same kind of homework-driven culture as most Chinese schools.
