Froebel believes that games are children's innate instinct, especially their activity instinct. Therefore, the education of children should not be bound, suppressed or encouraged, but should conform to the nature of children and meet their instinctive needs, just as gardeners conform to the nature of plants and fertilize them with appropriate sunlight and temperature. In this way, the divinity contained in people will be gradually awakened and reflected in human nature.

According to the above point of view, Froebel thinks that games and crafts should be the most important activities in early childhood, and the imparting of knowledge is only an additional part, interspersed among them. Kindergarten classes only need spoken English, not words. The most important responsibility of teachers is to correctly guide and design all kinds of game activities.

Froebel attaches great importance to the preparation of handmade materials and teaching AIDS, including famous gifts. He also attached importance to the setting of the environment and advocated that kindergartens must set up flower beds, vegetable gardens and orchards. Principle of self-activity: coach children's own activities, let children decide their own actions, let adults not interfere, let children know themselves and their own abilities, coach children to practice themselves, and stimulate their potential strength through their own actions and work.

Principle of sustainable development: Foucault's basic theory of "human nature education" has discussed the phrase "sustainable development", and human growth is sustainable development. Rousseau advocated that "education and ideas should start at the same time" in Emile.

Froebel believes that the development of human life is continuous at one point, and all stages of human development, such as infants, young children, children, adolescents, adults and the elderly, are continuous and interrelated internally. Froebel once criticized ordinary parents, saying that some parents require adolescent children to be like young people in all aspects. Froebel especially hopes that parents will not make such wrong demands on their children. The development of life is continuous, and such demand will hinder their future development. Froebel once emphasized that normal children should not receive special education from an early age. On the basis of human nature education, Froebel emphasized the germination of religious thought and morality. Foucault said that children's early feelings, especially children's smiles, are the initial expression of common feelings. This kind of social affection is based on the spirit of parents, brothers and sisters, that is to say, common affection is the initial germination and origin of real religious heart, which is cultivated by mother.
