Confucius, a great educator in the pre-Qin period in China, advocated "teaching without distinction" in terms of educational objects and "teaching students in accordance with their aptitude" in terms of teaching principles.

Teaching students in accordance with their aptitude is an important teaching method and principle. In teaching, according to different students' cognitive level, learning ability and their own quality, teachers choose learning methods suitable for each student's characteristics to carry out targeted teaching, give full play to students' strengths, make up for their shortcomings, stimulate students' interest in learning, establish students' confidence in learning, and thus promote students' all-round development.
