(1) Emotional principle: Love for education and students is a kind of potential wisdom, which is the motivation for teachers to improve themselves and enrich themselves. Respect and love students.

(2) Democratic principle: The ideological basis of teaching tact should be the democratic thought in teaching. Teachers' responsibility is to educate them, not to suppress students with authority, but to solve them with democratic methods and attitudes. Only by integrating democratic teaching ideas and teaching attitudes into our classroom teaching, and through our communication with students, can the interaction between us and students become truly emotional and achieve better teaching results.

(3) The principle of individuality: Teaching tact is a teacher's flexible application of educational ideas, teaching principles and teaching rules. Everything should be decided according to the situation at that time, that is, it should be different from person to person, from time to time, and guide the situation according to the situation. It is impossible to make a "one size fits all".

(4) The principle of seeking truth from facts: Only when teachers are familiar with the teaching materials and methods and understand the specific situation of students can they become familiar with it, which can not only cope with emergencies in the classroom freely, but also make the lively classroom atmosphere continue well. This kind of teaching wit should be pragmatic, conducive to classroom teaching and improving students' ideological and technical quality, rather than just putting on airs for the sake of "art"
