In Europe and America, many schools attach importance to teaching in small classes, and it is more common to control the class size to about 15 students. In the United States, for example, some high-quality primary and secondary schools and private universities often adopt small class teaching mode. According to the data of American educational research institutions, in the small class teaching environment (15-20 students in each class), students' academic performance has been significantly improved in reading, mathematics and other disciplines.
