阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。
In a society, such as the United States or Canada, which has many national, religious and cultural differences, people highly value individualism-the difference among people. Teachers place a lot of importance on the qualities that make each student special. The educational systems in these countries show these values. Students don't memorize information. Instead, they work individually and find answers themselves. There is often discussion in the classroom. At an early age, students learn to form their own ideas and opinions.
In most Asian societies, by contrast, people have the same language, history, and culture. Perhaps for this reason, the educational system in much of the Orient reflects society’s belief in group goals and purposes rather than individualism. Children in China, Japan, and Korea often work together and help one another in assignments. In the classroom, the teaching methods are often very formal. The teacher lectures, and the students listen. There is not much discussion. Instead, the students recite rules of information that they have memorized.
There are advantages and disadvantages to both of these systems of education. For example, one advantage to the system in Japan is that there much more math and science than American students learn by the end of high school. They also study more hours each day and more days each year than North Americans do. The system is difficult, but it prepares students for a society that values discipline and self-control. There is, however, a disadvantage. Memorization is an important learning method in Japanese schools, yet many students say that after an exam, they forget much of the information that they have memorized.
The advantage of the educational system in North American, on the other hand, is that students learn to think for themselves. The system prepares them for a society that values creative ideas. There is, however, a disadvantage. When students graduate from high school, they haven’t memorized as many basic rules and facts as students in other countries have.
