Because the purpose of education is the starting point and end-result of education, which is related to the general orientation of education development, we have to re-examine the concept of modem educational purpose in the post-modernism thought. The author holds that compared with the modem education view, the educational purpose view of the post-modem period shows the following characteristics： Maintaining the diversification and difference of individuahty, paying attention to cultivating social consciousness and critical ability, learning to understand and respect ecological harmony.展开更多
