Subjective teaching means that under the guidance of quality education and the purposeful, planned and organized guidance of teachers, students consciously and actively participate in teaching and other educational activities, and explore knowledge, find problems and solve problems independently. In this process, teachers are required to respect students' subjective status, teach students in accordance with their aptitude, and determine the teaching content, teaching methods and the degree of achieving teaching objectives from students' original knowledge level, learning characteristics and actual needs. Teachers' teaching should fall on students' learning, so that students can display their individuality, actively master the basic knowledge and skills of various subjects, develop their intelligence, develop good study habits, and develop their will, quality, emotion and behavioral ability.
