United States and Canada are multicultural countries with many national, religious and cultural differences, where people attach great importance to individualism--the uniqueness among people. Teachers value the qualities that make each student special and different. You can see such values through their educational systems. For example, students needn't memorize lots of information. Instead, they work independently and find answers on their own. There are discussions for children to show their own ideas and opinions. By contrast, people have the same language, history, and culture in most Asian societies. As a result, Asia's educational system reflects society's belief in group goals and purposes rather than individualism. Children in China, Japan, and Korea learn to work together and help one another in assignments. And the teaching methods are often very formal and serious. In class, teachers give lectures while students listen and take notes. Discussion is replaced by reciting rules of information that have been memorized. These two systems both have advantages and disadvantages. One advantage in Japan is that there is much more math and science than American students learn by the end of high school. In addition, students study more hours each day and more days each year than North Americans do. The difficult system also prepares students for a society that place emphasis on discipline and self-control. However, while memorization is an important learning method in Japanese schools, yet many students admit forgetting much of the information that they have memorized after exams. On the other hand, the educational system in North American has an advantage that students learn to think for themselves, which prepares them for a society that values creativity. The disadvantage is that when they graduate from high school, they haven't recited as many basic rules and facts as students in other countries have. The main idea of this passage is  _  .
