Epidemiology is a traditional subject mainly based on principles and concepts, and its teaching method needs further improving to meet the requirement of the new trend of education reform. Lecture-based teaching, problem-based teaching, case-based teaching, and internet based teaching, such as flip class, massive open online course and micro-lecture, all have its own unique merits in the practice of epidemiology teaching. So the combination of traditional teaching and online teaching is the most promising mode. "Rain class" , a mixed mode, is an efficient tool to present the epidemiology case more actually in class. Thus, teaching design and application of "rain class" are worth research.
流行病学是以原理和方法为主的工具学科，在教育改革的时代大背景下，流行病学的教学方法也应该汲取新的教育理念。传统教学模式、基于问题的教学模式、案例为基础的教学模式，以及网络教育模式中的"翻转课堂"、"慕课"、"微课"，在流行病学教学实践中都有各自的教学价值和欠缺之处。所以传统教学与网络教学相结合的混合教学模式是目前最有发展前景的教学模式，混合教学模式的智慧教学工具"雨课堂"可以在课堂上较真实的还原流行病学案例，基于"雨课堂"的流行病学教学设计及应用研究是一个值得探索的方向。.
