Drawing lessons from Europe, America, Japan and South Korea: Controlling the class size of primary and secondary schools and universities to 15 students to improve the quality of teaching and training.In a class of 15 students, the focus of education is not only the academic achievements of students, but also the development of students' moral cultivation and artistic accomplishment. Teachers can pay more attention to students' moral education and guide students to establish correct values. For example, by organizing class discussions on social equity, environmental protection and other topics, teachers can deeply understand each student's point of view and give targeted guidance.

In terms of educational concept, teachers also need to adapt to this change from large class teaching to small class teaching. Teacher training is particularly important. Schools can organize teachers to participate in training courses in small class teaching and learn the methods and skills of small class teaching, such as how to carry out personalized teaching and how to organize efficient group activities, so as to improve teachers' teaching ability to adapt to the new teaching mode.Schools can also relieve pressure by integrating resources. For example, make rational use of idle space on campus and transform it into classrooms, and share some educational resources through cooperation with the community. At the same time, improve the utilization rate of educational resources, such as using digital teaching equipment to reduce dependence on traditional teaching resources.When the class size is controlled at 15 students, teachers can know more about each student's learning situation. Teachers can provide targeted counseling for each student's weak points of knowledge. For example, in mathematics teaching, teachers may only explain the knowledge points in a large class, but in a class of 15 students, teachers can find each student's problems in algebra, geometry and other different sectors, so as to explain the problem-solving ideas in a personalized way.
