摘　　要：基于OBE教育理念,采用BOPPPS手段,探讨了密立根油滴实验的教学过程。通过对教学过程进行细化,建立学习目标,且对实验原理、油滴选取、电荷电量、元电荷计算等关键问题进行系统讨论,构建了参与式学习的关键过程。在该教学模式下,引导学生掌握密立根油滴实验中出现的实验难点、重点,学会独立完成密立根油滴实验,获得计算油滴电量和基本元电荷的方法,为实验课堂教学提供了一种新的教学模式参考。The BOPPPS teaching method based on the OBE education concept is adopted to study the teaching process of the Millikan oil drop experiment.The learning objectives are established through quantifying the teaching process,and the key issues such as experimental principle,oil droplet selection,charge quantity,and element charge calculation are systematically discussed.Moreover,participatory learning is also constructed and implemented.During the Millikan oil drop experiment,the students are taught to master the difficult and key points in the experiment,learn to complete the Millikan oil drop experiment independently,and obtain the methods of calculating the oil droplet electric charge and the fundamental element electric charge.This research finding provides a reference for a new teaching model for experimental teaching.
