When it comes to student development, we can't help but mention the role of teachers. Today's managers should think about the development of teachers and students, and promote the development of students with the development of teachers. When students develop, they will put forward higher requirements for teachers' professional development. In a sense, the sum of teachers' professional development and students' development is the development of the school. Under the "student-oriented", do you still need a "teacher-oriented"? The ideal relationship among student development, teacher development and school development is that school development must be based on social development, school management must be based on teacher development, and school education must be based on student development. Teachers' development is the foundation and platform of students' development, and it is also an important connotation of school development. From this perspective, teacher development plays a very important role in the development of schools and students. On the one hand, schools are required to establish a community of students, teachers and schools, on the other hand, teachers' professional development needs to be promoted. Li Yongpei believes that teachers should grasp three points in their development. First of all, we should fully and correctly understand how to embody the life value of teachers. The value of teachers is reflected in many aspects, among which the intrinsic value of teachers, especially the surging of life, the value pursued and the real understanding of the profession, is far from being taken seriously. Secondly, the training system is an important aspect that affects the value of teachers and needs to be improved or even reconstructed.
