The educational model of the Soviet Union emphasizes specialization. Students who divide arts and sciences too early in high school will be fixed when they enter the university major. Facts have proved that this system has serious defects. First, it causes students to have narrow knowledge and weak innovation ability. Second, because the major is divided too early, once it is divided, it is difficult to change, so most people only do one job all their lives. If this major is not your interest, you are unlikely to be creative all your life, let alone become an excellent innovative talent. "

Correspondingly, it is the general education system represented by the United States, which not only implements general education before graduating from high school, but also tries to downplay majors at the university level. More importantly, it communicates all kinds of education within the system, so that all students can transfer to other types of education no matter what their initial choice is, as long as they have the conditions and interest.
