Finally, in a multicultural society, the same national curriculum may become the block of culture development, especially the minatory culture. Different ethnic communities should be given the opportunity to preserve and promote their traditional cultures. The main approach of culture development among students is education. And the curriculums of ethnic cultures are better designed by local education communities for they get a further awareness of local cultures. Minatory students may poorly understand their culture without the special curriculum on their ethnic culture. On the other hand, the inheritance of ethnic culture is weaken.
These are only three cases of why the requirement is unrealistic. Before paying serious attentions to regional difference in geography, finance and race, blindly requiring all of its students to study the same national curriculum until they enter college is not an advisable approach.
