Before Dr. Montessori put forward her "new education", the old education only included two elements: teachers and children, that is, education and teaching were only regarded as both teachers and children. Her new education includes three elements: teachers, children and the environment. Montessori pointed out: "The most fundamental feature of our education system is the emphasis on the environment. In the new education system, in addition to the relationship between teachers and children, both teachers and children should be related to the environment.

Although children's psychological development is guided by their inner instinct, the external environment provides the necessary media for children's psychological development.

Only by preparing a suitable environment for children can we create a new era of education. "

From then to now, teachers, children and the environment have formed a golden triangle in the process of preschool education. It is unthinkable to talk about preschool education without the environment.
