John dewey, a famous American educational philosopher, creatively established four propositions of educational philosophy: "Education is the constant transformation of experience", "Education is the social process", "Education is life" and "Education is growth". These four propositions are internally unified. "Education is the constant transformation of experience" is a basic proposition, which puts forward that the essence of education is the constant transformation and development of children's experience. Education based on experience should naturally be organized in the form of social life.
