"Learning by doing" was put forward by American educator Dewey. Dewey believes that "all learning is a by-product of action, so teachers should" do "to make students think and learn knowledge.

In teaching, teachers should regard students as concrete and dynamic people and respect their personality and life. In the classroom, teachers should follow the principle of discovery and inquiry, do everything possible to stimulate students' interest in learning knowledge, combine some selective extracurricular activities with creative social practice activities, form an open and multidimensional extracurricular activity system, and provide students with time and space to freely discover, try, exercise and express their talents, and provide students with rich and varied opportunities to learn and flexibly use book knowledge.

Mr Tao Xingzhi said, "We should be doing middle school, doing middle school". Teachers teach while doing, and students go to school while doing. From the perspective of teacher-student relationship, doing is teaching; From the relationship between students and teachers, doing is learning. Doing middle school is real teaching; Students learn by doing, which is practical learning. If you don't work hard, you can't teach or learn well. It can be seen that in classroom teaching, both teachers' teaching and students' learning should focus on "doing", complete the task of teaching and learning on "doing" and realize the integration of teaching and learning.
