Montessori called children's learning activities "work". She believes that work can coordinate children's muscles and body movements, use their hands and brains, and promote the coordinated development of body and mind. Through children's free choice, independent operation and dedication to work, they have honed their will, strengthened their self-control, courage and self-confidence, cultivated their independent spirit, and strictly disciplined them, which also met their psychological needs.
Montessori believes that children have an innate "inner vitality", which is positive, constantly developing and has infinite power; The task of education is to stimulate and promote the development of children's "inner potential"; Children are not containers for adults, nor are they clay and wax that can be shaped at will. Teachers and parents must seriously study, observe and understand children's inner world, and help children achieve physical and mental development in free and spontaneous activities. Accordingly, Montessori designed a set of effective training methods for preschool children to guide them to grow up quickly.
