In Japanese schools, from elementary schools to universities, teachers direct what students should do or how they should be.
Students follow the school rules and the directions of teachers.
In American schools, on the other hand, students have to be more independent than Japanese students in many ways. Because of differences between Japanese and American schools, Japanese students who begin to study in an American school are shocked, and they take a pretty long time to adjust themselves to the way of American schools. First, many Japanese students are surprised by American schools because American students pay much attention to teachers, and also they interrupt teachers to ask questions or to express their opinions. The style of teaching in the U.S. is completely different from Japan, especially in two points. One difference is that teachers in Japan expect students to be quiet in classes.
