"Learning by doing" is the basic principle of all Dewey's teaching theories. Dewey believes that all learning is a by-product of action, so teachers should "do" to make students think and learn knowledge. Dewey integrated "learning by doing" into all major aspects of teaching, such as teaching process, curriculum, teaching methods and teaching organization forms. Are based on the requirements of doing middle school.

Dewey put forward the teaching theory of "learning by doing" based on the theory that education is "life", "growth" and "experience transformation". Traditionally, teaching is to impart knowledge. However, Dewey thinks that the knowledge that students get from teachers is not real knowledge. This teaching method can only inhibit children's vitality and hinder the development of children's creative talents.

Teaching should not inject knowledge directly, but should induce children to participate in activities wholeheartedly and gain experience and knowledge unconsciously in activities, so they should "learn by doing". Doing is fundamental. If you don't do it, there will be no support for your child's study. "Learning by doing" emphasizes starting from and attaching to children's real life.

The teaching process is the process of "doing". In his view, if children don't have the opportunity to do it, it will inevitably hinder their natural development. Children are born with a desire to do things and work, and have a strong interest in activities, so special attention should be paid.
