In recent years, there have been more and more practices about hybrid teaching mode, and the interactive classes are popular among college teachers and students. College students’ learning style is changing from passive learning to active learning. However, it is also impractical to attach too much importance to students' learning autonomy and neglect teachers’ guidance in teaching. College teaching should not only pay attention to the interaction between teachers and students, but also pay attention to teachers’ guidance. Therefore, a positive circle of “teachers’ guidance → teacher-student interaction → autonomous learning” is formed.
