This article only starts from the perspective of the chemistry discipline. Good teacher-student relationship is the prerequisite for creation, emotion is the necessary condition for maintaining, interest is the internal driving force for regulation, motivation is the catalyst for active classrooms, and flexibility is the regulator and design of creation. The activator of suspected creation is discussed in several aspects.
