① Development determines education. The development of children restricts the difficulty of preschool education and determines the content and formula of education. Children's development restricts education, and education is subordinate to development. For example, the thinking of 3-6-year-old children is mainly based on concrete image thinking, which has not yet reached the level of abstract logical thinking. Therefore, kindergarten education is best based on the representative level. For another example, the life ability of kindergarten children is not yet mature, so random education has become the most suitable teaching method in life and games.

On the other hand, education can create development. Without education, children can't become a real person, but a pure organism, so education determines and restricts development.

③ The creation of education for development is not arbitrary, and the development of educational creation must follow the natural law of children's development and conform to the natural process of development. Therefore, education and children's development are mutually restricted and determined.
