Teachers should change their roles and achieve equality between teachers and students. In the past, teachers regarded themselves as knowledge authorities, despised students' wisdom, ignored students' personal dignity and ignored students' creativity. Under the pressure of teachers, students lost their subjective consciousness and became buckets filled with knowledge, with sad results. Now, teachers are the leaders of students' learning, so we should put down teachers' dignity, strengthen the cultivation of teachers' morality and style, and treat every student equally not only from the standpoint but also from the soul. Students can open their closed hearts on the basis of equality and eliminate their original fear of teachers. In this way, the psychological distance between teachers and students is getting closer, and there is no obstacle to the interaction between teachers and students. Equal teacher-student relationship is the foundation of democratic classroom. With democracy, teachers and students can interact, and the effectiveness of this interaction is reliably guaranteed. Only by respecting students' personality and quality and giving them time and space to study independently can students' enthusiasm and creativity be fully exerted.

The interaction between teachers and students in the teaching process is used to solve problems, which is the expected goal. With the expected goal, the interaction between teachers and students will not become a mere formality, but also make the interaction process orderly. On this basis, teacher-student interaction can produce results. In the process of solving problems, teachers and students can exceed the expected goals and produce new problems, so that the understanding of the problems will be deeper and more comprehensive, which can better reflect the effectiveness of teacher-student interaction.

In short, effective teacher-student interaction can make teachers and students respect each other and develop together in mutual learning. Teachers' good ethics is the basis of this relationship. Because students' hearts are always open to teachers who they think are worthy of respect and high morality. Therefore, as teachers, we should put students first, not look down on them. Only in this way can we enter a new realm of quality education through the bridge of teacher-student interaction.
