In the process of education, students are the object of education; Teachers are the organizers and leaders of the whole educational process, which determines that students are in the object position in the educational process; At the same time, the characteristics of students' plasticity, dependence and learning from teachers also show that students are in an object position. On the other hand, students are developing and have subjective initiative. Students' activities in the process of education are conscious and purposeful, and they are always active participants in educational activities. As conscious and independent people, students' subjective initiative determines that they are the main body of self-education and development.

The role of teachers is dominant and students are the main body: in educational activities, the role of teachers is dominant and students are the main body. Guidance is not everything, but how to "guide" is the center of key education, which refers to the starting point for teachers to consider educational activities as educators. For teachers, the center of education should obviously be students. It can be said that teachers are the center of running a school, but not the center of educational activities. In addition, they are all self-centered, which will encourage teachers to think in an excessively "self" context. In fact, teachers should think more about education in the context of "no self" and regard students as the primary existence in educational activities.
