To talk about this problem, we must first analyze the educational systems of China and the United States clearly. China's tradition is a typical "spoon-feeding" teaching method, with teaching as the mainstay and learning as the supplement. The more students learn, the narrower their thinking becomes, and the more they learn, the more fixed their thinking becomes. The United States is an open teaching, and there is no fixed and absolutely correct answer, only a relatively more comprehensive and reasonable answer. Students' thinking is improved by divergence. Second, the national conditions determine. When it comes to national conditions, we still don't say it, and readers understand it themselves. Finally, the brutal intervention of parents. Parents' excessive intervention and utilitarian education are another major factor leading to educational failure. I believe every student in China has a deep understanding, so I won't go into details here.
