(1) Education means "life", "growth" and "reorganization and transformation of experience". Education can transmit the accumulated experience of human beings, enrich the content of human experience, and enhance the ability of experience to guide life and adapt to society, thus maintaining and developing social life. Broadly speaking, individuals contact with others in social life, interact with each other, gradually expand and improve their own experience, develop moral quality, and acquire knowledge and skills. This is education. Dewey's conclusion is that "education is life", "education is growth" and "education is the reorganization and transformation of experience", because the transformation of experience must be closely combined with life and can promote personal growth.

(2) the theory of aimless education. Dewey believes that in an undemocratic and unequal society, education is only the purpose imposed on the educated by external forces. A democratic society is different. We should pursue the theory of aimlessness. In the era of class struggle and proletarian revolution, Dewey emphasized the effectiveness of education in improving society. The bourgeois nature of Dewey's teleology of education is obvious.

(3) "School is society". Dewey believes that people participate in real life in society. It is a proper way for physical and mental growth and experience transformation. Therefore, teachers should turn the classroom of imparting knowledge into a paradise for children's activities, guide children to actively participate in activities, unconsciously develop moral character and acquire knowledge in activities, and realize the transformation of life, growth and experience.

(4) Teaching theory. Based on the theory that education is the transformation of life, growth and experience, Dewey discussed teaching materials and teaching methods different from traditional concepts.

(1) In the selection of teaching materials, Dewey proposed that "the real center of interaction between schools and disciplines is not science … but children's own social activities". Specifically, the school arranges all kinds of homework and introduces basic human things into the school as teaching materials.

(2) Dewey advocated "learning by doing" in teaching methods. He thinks that the knowledge that children gain by listening to lectures and reading books instead of activities is illusory.

(5) Moral education theory. Dewey said: "Morality is the highest and ultimate goal of education." "Moral process and educational process are unified." Dewey believes that moral education plays an important role in education. Dewey strongly emphasized that morality is the force to promote social progress. In practice, Dewey first advocates "cultivating children's moral quality in activities", and then requires combining intellectual education to achieve the purpose of moral education. Thirdly, he attaches great importance to the moral education function of educational methods.
