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.It is also more beneficial to the cultivation of students' artistic and sports specialties. Teachers can discover the potential of each student in painting, music and sports, and provide them with more opportunities for guidance and participation in related activities. For example, in music class, teachers can give each student more time to practice solo and improve their singing skills.
