"Life education" is the core of Chen Heqin's educational thought. The content of "life education" is very rich, mainly including teleology, curriculum theory and teaching theory. Feeling the disadvantages of traditional education in China and the national survival crisis faced by China at that time, Chen Heqin clearly put forward that the purpose of "living education" is to be a person, a China person and a modern China person. Among them, "Be a modern China person". Second, we must have the ability to build; Third, we must have creative ability; Fourth, we must cooperate; Fifth, we should be willing to serve the society and the people. Obviously, these five conditions reflect the requirements of all-round development of morality, intelligence and physique. In view of the fact that traditional education regards books as the only material for school study and reading and teaching as the actual situation of school education activities, Chen Heqin summarized "nature and society are living materials" as the curriculum theory of "living education". "Living textbooks" do not deny books. Instead, it emphasizes the importance of children gaining experience and knowledge through personal observation and contact with nature and social activities, and advocates combining book knowledge with children's direct experience. To tell children about fish, we should let them see the real fish, observe its breathing, swimming and even dissect its body, and study its various parts. The knowledge gained in this way is true and cordial, and it can also stimulate children's interest in learning and research spirit. With the change of course content, its organizational form has also changed. Chen Heqin believes that the curriculum form of "life education" should conform to children's activities and lifestyles, and to the way children communicate with the natural and social environment. Therefore, the course of "living education" breaks the traditional discipline organization mode and changes to the form of activity center and activity unit, including five activities, which are called "five groups of activities" That is, children's health activities (including sports activities, personal hygiene, public health, mental health, safety education, etc.). ), children's social activities (including zoos, botanical gardens, labor factories and scientific research institutions, etc. ), children's art activities (including music, art, handicrafts, drama, etc. ), as well as children's literature activities (including fairy tales, poems, riddles, stories, scripts, speeches, debates, calligraphy, etc. ). So it is also called "five-finger activity". The basic principle of "living education" teaching theory is "learning by doing, learning by doing and making progress by doing". There are 17 educational principles. "Life education" is an educational thought with absorption, innovation and China characteristics, which has had an important influence in history and still has inspiration for the current educational reform.
