Abstract: For the fact of attaching great importance to the experimental results but not the experimental process in the teaching of photoelectric effect experiment,this paper shows the breakthrough point of cultivation of students’ comprehensive quality in the experiment teaching through the design of the background of experiment,experimental method and the processing of data of experiment. It guides the students to focus on the successful experiences in the process of discovering the photoelectric effect,explaining the photoelectric effect and verifying the photoelectric effect,analyze the clever way called “transformation” which is used to use in experiment,and master the skills of the experimental operation and data process. All these does not only cultivate students’ innovation ability but also improve student experiment skills,which make the physical experiment of university play an important role in the cultivation of students’ comprehensive quality.
