In educational activities, teachers, as the educational purpose of a certain society, undertake certain educational tasks, make use of certain educational resources and carry out educational practice activities for students on the basis of their own knowledge and skills. There is no doubt that teachers are the main body of educational practice.

"Teacher, so preach, teach and dispel doubts." The specific work of teachers lies in "preaching, teaching and solving doubts", that is to say, teachers should impart knowledge to students through their own teaching practice, cultivate students' practical ability and let students understand and know all kinds of things.

This requires teachers to have the spirit of "never tire of learning and never tire of details" to broaden students' knowledge horizons, enrich students' knowledge reserves, and cultivate students' ability to use knowledge to solve practical problems on this basis.

At the same time, teachers should have lofty ideals, perfect moral sentiments, firm beliefs and tenacious will, and use them to exert a subtle influence and edification on students. Only in this way can we cultivate useful talents needed by the motherland, develop in an all-round way and adapt to the competitive situation.

Secondly, we should love our education object-students. A teacher should be a master sculptor, who can carve a blank into a beautiful work of art with his own thoughts and feelings.

In essence, students are neither good nor bad. The reason why "poor students" are "poor" is that their potential is bound by various subjective and objective factors and has not been fully released. Subjective factors and objective influences of students themselves.
