In the traditional epistemological framework,knowledge is regarded as a true belief,while curriculum knowledge is a refined encoding between knowledge and curriculum.From the perspective of educational sociology,knowledge is an important tool for maintaining the social and cultural structure,and curriculum knowledge plays its due role in reproducing the mainstream culture of society.On the contrary,the perspective of cultural education regards knowledge as a positive force for promoting students'mental health development,and curriculum knowledge becomes a cultural text for constructing and enriching students'individual life spirit,which triggers thinking and enlightenment on the cultural return of knowledge.The cultural return of knowledge is based on the return of teachers'role as intellectuals,and its core lies inpaying attention to students'learning process,fundamentally returning to the conscious position of cultivating students with educational knowledge in a cultural way.This return not only defends the justice of knowledge,but also respects the dignity of knowledge.
