To carry out the idea of quality education, we must recognize the individual differences of students, embody the principle of teaching students in accordance with their aptitude, and fully develop students' individual specialties. In education, we should not only grasp the overall characteristics of students, but also give consideration to their individual characteristics. Therefore, to implement quality education in the true sense, we must seriously reflect on the traditional classroom teaching system and find out its shortcomings. Students' grades are not good, except for teachers' teaching activities, which mainly focus on imparting knowledge. Ignoring the factors related to students' intellectual development, ignoring students' individual differences in knowledge and ability, and failing to implement the principle of teaching students in accordance with their aptitude is probably the main reason why it is difficult to effectively implement the principle of teaching students in accordance with their aptitude in practice, which is not only influenced by teachers' educational concepts, educational arts and educational means, but also closely related to the one-size-fits-all educational and teaching objectives. It is also related to the limitations of the traditional class teaching system, so it is very necessary to reform the traditional class teaching system, and the best way to reform is the idea of hierarchical teaching, which originated from Confucius' teaching in accordance with his aptitude. Hierarchical teaching can truly achieve the goal of students' development-oriented, teaching students in accordance with their aptitude and mobilizing students' initiative in learning. Highlight the cultivation of students' innovative spirit and practical ability, promote students' balanced and harmonious development, promote students' overall quality improvement and personality development, encourage students with spare capacity and expertise to develop ahead of time and create conditions, and encourage students with poor learning foundation to achieve academic success and develop accordingly, so as to achieve the goal of running a school with everyone's success and personality development, which meets the requirements of quality education.
The strategy of rejuvenating the country through science and education requires vigorously promoting and implementing quality education, and the essence of implementing quality education is to let all students develop comprehensively and actively. Teaching students in accordance with their aptitude is the core method and principle of this process. But the reality is often that students are mainly regarded as passive people who need education, paying attention to the evaluation of students' realistic state (dividing students into good but poor according to their academic performance) and ignoring their potential development possibilities. Accustomed to measuring according to unified standards and scales, students are asked not to pay attention to their individual differences. To cultivate children, just like gardeners, we must first know them, discover their characteristics, give them suitable ingredients, water and sunshine, and eliminate pests. Only in this way can they thrive because of the influence of congenital conditions such as heredity and surrounding environment, as well as the acquired education, and can they fully understand the development of students.
