Teachers' teaching efficacy affects teachers' behavior, and teachers' behavior will inevitably affect students, and teaching efficacy will also be affected by various factors. Tao Xin et al. (1996) think that teachers' teaching efficacy affects students' self-efficacy and learning ability and achievement by influencing teachers' behavior, and students' self-efficacy and learning ability and achievement are interactive. At the same time, environmental factors and teachers' own factors also have an impact on teachers' teaching efficacy. The factors that affect teachers' teaching efficacy can generally be divided into external environmental factors and teachers' own factors. External factors include social atmosphere, conditions for teachers' development, interpersonal relationships, etc. The research of Tao Xin et al. (1994) shows that the conditions of work development and the objective conditions of schools have obvious influence on the general sense of educational efficacy; Work development, school atmosphere and teacher-student relationship have obvious effects on teachers' personal teaching efficacy. The teacher's own factors include his values and self-concept. The external environmental factors that affect teachers' teaching efficacy mainly include the social environment, the environment around the school and some factors inside the school, such as whether teachers' educational concepts are scientific and interpersonal relationships within the school.
