mode”is used in the practice of university physics experiment teaching. Hierarchical teaching of the same teaching nature

class is realized in the three dimensions before class，classroom and after class. The introduction of the rain classroom

fundamentally solves the problem of low classroom efficiency in the teaching mode of different layer-same classdifferent

method，especially for students who do not have physics in the college entrance examination. Multi-dimensional

hierarchical teaching based on rain classroom not only stimulates students' enthusiasm for learning，meets the learning

needs of students，but also realizes personalized and effective teaching and enhances teachers’sense of accomplishment.
