The educational theory advocated by Dewey is called pragmatic pedagogy. Dewey believes that school is society, and Wei advocates that education is the transformation of life, growth and experience. In an undemocratic and unequal society, education is only the purpose imposed on the educated by external forces, while in a democratic society, we should pursue the theory of aimlessness. Pragmatic pedagogy is an educational trend of thought that rose in the United States at the end of 19 and the beginning of the 20th century. John dewey's main viewpoints are: education is life, education is the growth of experience, school is society, learning by doing and children's center. In an undemocratic and unequal society, education is only the purpose imposed on the educated by external forces. In a democratic society, we should pursue teleology.
