The law of individual differences in physical and mental development determines that education must teach students in accordance with their aptitude.

The individual differences in individual physical and mental development require that education should adapt to the differences in human development, teach students in accordance with their aptitude, and give full play to the potential and positive factors of each student.

Individual differences: there are differences in the degree and speed of individual physical and mental development, and between different aspects of individual physical and mental development. People's innate quality, environment and education, and their own subjective initiative determine that there are individual differences in people's physical and mental development. Enlightenment: Educators should pay attention to students' individual differences and achieve "teaching students in accordance with their aptitude".
