The teaching method is another reason for the result of the American have more Noble prize winners than China have. Chinese teachers like to teach students based on only the textbook which not contain many new materials. During the class, the teacher is always talking about what they have prepared. To respect the teacher, if students have questions, they have to wait until the class is over and talk to the teacher privately. So, most students learned what the teacher said in class.
Students always feel that when they have finished their assignment and they have learned.
In contrast to China, the U.S college teachers like to teach the students based on both textbook and ot her new materials. In the class, students can talk freely with the professor whenever they have questions. Some professors like to say that they don't know or they are not sure, etc. This is seldom seen in China. If students want to know more about something, they have to find out by themselves.
