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.Japan and South Korea also have experience in class size control. Japanese school education emphasizes refined training, and the class size is generally small. In a class of 15 students, teachers can pay close attention to students' psychological state and learning progress. Japanese educational circles believe that a small class size helps to create a good teacher-student relationship, which has a positive impact on students' physical and mental health and learning motivation. According to the survey, in small class teaching in Japan, students' participation in class has increased by nearly 30% compared with that in large class.This class size is also convenient to carry out inquiry learning. Every student has more opportunities to participate in discussions and experiments, and it is no longer a few students who dominate classroom interaction. In science class, 15 students can be divided into several groups to carry out experimental exploration, and each student can operate the instrument, observe the experimental phenomena and put forward his own opinions. This is helpful to improve students' scientific inquiry ability and innovative thinking ability.
