First, education should adapt to the order of individual development and promote students' physical and mental development step by step. Man's physical and mental development is a continuous development process from low level to high level, from simple to complex, from quantitative change to qualitative change. Therefore, education should be gradual. All the teaching of knowledge and skills, the development of intelligence, the enhancement of physique and the cultivation of ideology and morality should follow the order from concrete to abstract, from simple to complex, and from low to high. We can neither "encourage others by pulling out seedlings" nor "practice with dignity", let alone suppress students' development and passively accommodate their existing development level.

Second, education should adapt to the cyclical law of individual development and pay attention to the "connection" between each stage. This law determines that education must be carried out in stages according to the characteristics of different ages. The requirements, contents and methods of education and teaching should not be uniform, and students of different ages should not be confused. At the same time, we should also see the mutual connection between different age stages, which should not be completely separated artificially, and pay attention to the "convergence" work between different stages.

Third, education should adapt to the imbalance of individual development and strengthen the education of students in the critical period of physical and mental development. There is an optimal or critical period for the individual's physical and mental development. In order to effectively promote the physical and mental development of individuals, education should seize the critical period in order to achieve the best results in the shortest time.

Fourth, individual differences in individual physical and mental development, so as to teach students in accordance with their aptitude. This law requires that education should not only recognize the common characteristics of students' development, but also pay full attention to the individual differences of each student and teach students in accordance with their aptitude. Give full play to each student's potential and positive factors, choose the most effective education method, and let each student get maximum development.

Fifth, the complementarity of individual physical and mental development stimulates students' confidence and enthusiasm for self-development. This law requires educators to first establish firm confidence in all students, especially those with physical and mental disabilities and backward academic performance; Secondly, we should master scientific education methods, be good at discovering students' advantages, foster strengths and avoid weaknesses, be good at recovering losses, stimulate students' confidence and enthusiasm for self-development, and realize the coordinated and unified development of body and mind.
