Environmental Adaptation Theory: "Adapting to the environment" is also the instinct of all things. People are born with the instinct to adapt to the environment, help human beings survive, and even drive themselves to develop physiological or psychological functions necessary for future survival. In other words, all kinds of intelligence and physical fitness of human beings grow because they adapt to the environment!

Independent growth theory: Montessori said: "If anyone can't be independent, he can't talk about freedom". As parents of children, we can help children to be independent: let them do it, respect, guide them in time, be patient and encourage them!

Theory of natural development of life: In the growth process of 0-6 years old, children are driven by internal vitality, and the process of assiduously absorbing the characteristics of something in the surrounding environment and repeatedly practicing it is the sensitive period.

Absorbing mind theory: We use our minds to acquire knowledge, but children directly absorb knowledge into their own spiritual life. Dr Montessori found that children have absorptive capacity through observation, which directly led to an educational revolution.

Humanity at work: Dr. Montessori found in her observation that children prefer work to play. Montessori believes that work is the instinct of life and the characteristic of human nature.

Useless theory of rewards and punishments: children who are often encouraged are based on their own cognition and self-discipline. The reward-type reward will only induce him to do it if he has a prize, which will affect his future values and will only be measured by fame and fortune.
