Abstract: Based on the teaching platform of "Rain Classroom", 69 students majoring in biological sciences of Cangzhou Normal University in 2018 were selected as the research objects to explore the teaching mode of reversed classroom suitable for botany course of Biological Sciences specialty, and to formulate the teaching implementation plan. Through "information transmission" before class and "assimilation and internalization" during class. ” After-class "consolidation and promotion" three links to implement teaching. The results showed that 62 students recognized that botany course was suitable for flipping class, and 66 students recognized the improvement of classroom efficiency.
