In Montessori's view, the environment that children are exposed to after birth is actually an "adult civilized environment" created by adults for the convenience of their own lives. This environment does not meet the needs of children's physical and mental development, and children's needs are different from those of adults. Montessori believes that children can achieve the best learning state in a well-prepared environment. Can let children get normal and sustainable development.

This prepared environment is the main place for children to live. They can move independently and freely, get learning materials and accumulate experience in an orderly way, and minimize the interference of adults. Therefore, adults must understand the characteristics of children's physical and mental development and provide a "prepared environment" suitable for their "potential vitality" development.

Montessori's educational idea;

Montessori's educational thought can be simply described as that children have a mental embryo, or that children have a psychological development model before they are born. If a mental embryo wants to develop according to its planned model, it must have two harmonious and unified conditions-environment and freedom.

Children rely on their great potential to develop towards their goals, because children have some special abilities: sensitive period and absorptive thinking. Therefore, children gradually create their own psychological structure and finally achieve normal development. In this development process of children's growth, children's psychological development follows the laws of nature.
