"School is society and education is life" was really put forward by American educator Dewey. Dewey is the most important educational reformer in the 20th century and one of the representatives of the progressive education movement. It emphasizes the connection between school and society, and thinks that school should be the epitome of society, and education should be close to life and combined with students' practical experience to cultivate students' practical application ability and social participation ability. It is advocated that schools should provide students with real learning environment and experience, and learn and grow through practice and participation in social activities. Dewey's educational thought still has an important influence on modern education.
