College Physics Experiments is an important public basic course in science and engineering. Atpresent,the exploration of Problem Based Leaming( PBL) in this course is not sulicient ,and it is necessary todesign and practice it to further improve the teaching elfectiveness of university physics experiments. Byanalyzing the current teaching situation and the problems that need to be solved, the first step is to start withthe construction of the teaching staff, and solve the problems of teachers "ideological preparation andcollaborative cooperation. Then, taking the experiment “ Adjustment and Use of Speetrometer" as an example ,discuss the structure of course problems and the integrated design during all teaching stages before , in , andafter class. 'he results of the questionnaire survey indicate that the implementation of PBl, can enhaneestudents’ interest in learning and enhance teaching effectiveness. lt provides reference for the application ofPBL teaching mode in College Physics Experiments teaching.
