At the teacher meeting of Chinese Undergraduate Physics Experiment Competition (CUPEC) held in January 2020, teachers played in role of students. All the participated teachers finished the task by five main periods, which include doing experiment, answering the competition worksheets, correcting papers, group discussion, summary and report. In this paper, we summarize the role inversion teacher meeting, and discuss the direction of physics experiment teaching reform from the aspects of experiment content setting, improvement of experimental teachers, the cultivation of students and teachers' communication, so as to explore the ways to improve the quality of undergraduate physics experiment.
