     In a society such as the United States or Canada, which has many national, religious, and cultural differences,

people highly value individualism (个人主义)-the differences 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 do not 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, on the contrary, people have the same language, history, and culture. Perhaps for

this reason, the educational system in much of the Orient (东方的) 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 on 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 repeat rules or 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 students there learn 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 they have memorized.

     The advantage of the educational system in North America, 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.
