Dewey's pragmatic education theory comprehensively and deeply discusses many problems related to education, which is the largest and most complete educational theory system in modern western countries. In Dewey's educational theory, we try to get rid of the either-or metaphysical thinking mode and try to unify the "dilemma" problems in education as much as possible, such as child-oriented and social-oriented, teacher-centered and child-centered, activity curriculum and subject curriculum, personal experience and group experience, scientific logic and psychological logic.
