At the beginning of the 20th century, fundamental changes have taken place in the international concept of education, that is, the concepts and ideological systems of "education in the traditional sense does not exist", "education is a psychological project" and "education is to start the potential of the educated themselves" have been formed. Decades later, this reform has created a number of developed countries. Around the new century, this new educational concept has been firmly established. In China, this change has just happened and is in the primary stage. Internationally, Montessori School enjoys a high reputation and is recognized as the best of all schools. Montessori teaching method is regarded as an introduction to new education because of its excellent reputation and training institutions all over the world. The core of Montessori method is children's self-development under the guidance of their own inner "spiritual embryo", while schools and teachers "seize the sensitive period" and are always ready to "help" children mentally, psychologically. This requires special operating techniques to realize this principle. But the most important thing is the change of ideas. The most important thing for the change of ideas is to understand the soul of new ideas. This is the hardest. Therefore, although China's educational experiment seems to have collapsed, most of it belongs to the status quo. People began to realize that the implementation of Montessori method is extremely difficult. Child development is a science. It needs special qualities and years of study and research. Most adults, including most parents and teachers, have no chance to understand, and naturally they don't understand the inner needs of children. They rely on their subconscious, subconscious, early experience, imagination, self-feeling and emotions at that time to "take care of children", talk with children, get along with children and deal with their problems, which has caused many psychological problems to most children. "Normal children" are rare. In this case, the Montessori method can first adjust the child's psychological barrier and make it gradually return to normal. Montessori method can make normalized children develop normally. Such a child is lovely, excellent in quality, with potential and strength of personality. When they grow up, they can give full play to the great natural life potential of human beings, which is rarely explored and invoked by most people now. Leaving traditional ideas and accepting Montessori's thoughts and methods is a great liberation of thoughts, a change of ideas and a renewal of the soul. The reasons and conditions for the possibility of this change are the love for children and relatives, the response of people with creative thinking tendency to the call of science and the eternal youth in people's hearts. At the beginning of this century, a well-known American scholar predicted that there will be two major industries in 2 1 century, one is high-tech industry, and the other is scientific children's education. Humans have realized that children's scientific development is no longer limited to experiments, but socialization. People's foundation trees talents, and buildings' foundation trees tall buildings. Contemporary psychology scientifically reveals the decisive role of childhood in a person's life. 0-6 years old is the cornerstone of life. At the beginning of the new century, people in China have begun to realize the importance of preschool education. People are realizing that the pre-school education in China should get rid of the concepts of "companionship" and "care" on the one hand, and the misunderstandings of early childhood education such as "children's songs in Tang and Song Dynasties", "little knowledge of astronomy and geography" and "scattered primary school content" on the other hand. People are realizing that it is difficult for parents without strong love and sacrifice to have the real right to take care of their children. Nannies without strict training will not take care of children, and even intolerant grandparents should not take care of children. Not only is it dangerous to take care of children, but it is also dangerous to have contact and dialogue with children. It is unwise for preschool education institutions without new educational scientific guidance and training. The whole society is realizing: how to distinguish the development and state of children? How can we identify normal children! What kind of development is normal? What kind of children's growing environment is qualified? This highly professional question has been commented by "amateurs" on most occasions. Children are placed in an unqualified humanistic growth environment. Not only is the social environment unqualified, but most school environments are also unqualified. Therefore, China's "human production" is in a state of producing only "low-quality population". Educational reform and opening up, educational system transformation, quality education, introduction of educational methods and educational investment are becoming the call of the whole society.
