Dewey's main viewpoints include: ① Education is life. Dewey believes that education is the process of children's life now, not the preparation for their future life. Accordingly, Dewey put forward that "school is society". Dewey believes that since education is a process of social life, school is a form of social life. He emphasized that schools should "become a small society and a primary society". In school, we should simplify the real social life into an embryonic state and present the children's current social life. ② Education means growth. Because life is growth and children's development is the process of primitive instinctive growth, Dewey emphasized: "Growth is the characteristic of life, so education is growth." ③ Education is the constant transformation of experience. Experience is the core concept in Dewey's pragmatic philosophy and pragmatic education system. He believes that education is a continuous process from known experience to unknown experience. This process is not to teach children existing scientific knowledge, but to increase their experience in activities. The acquisition of experience is inseparable from children's personal activities, so Dewey put forward another basic principle of education-"learning by doing", which he believes is the central principle of teaching.
