Abstract: How to stimulate college students interest and enthusiasm for "College Physics Experiments" is an important issue currently faced in College physics education reform. Reshaping the "College Physics Experiments" syllabus based on students professional backgrounds is a crucial approach to overcome such difficulty. This case study uses the "Light Polarization Experiment" as an example. Building upon the basic requirements of standardized experimental projects in college physics, it introduces advanced polarization optics experiments that align with students majors and vector polarization optics experiments related to cutting-edge research. It also adds after-class extension experiments closely connected to real life. The teaching method adopts a blend of virtual and real scenarios, using situational inspiration. It organically integrates ideological and political elements into the experimental teaching process, stimulating students learning interest, cultivating a rigorous and pragmatic scientific attitude, and fostering a spirit of exploration and innovation. This approach has developed students scientific enthusiasm and research potential, fully embodying the guiding ideology of "three-integrity education" and the teaching design concept of “high-leveled, innovative and challenging characteristics”. It is highly extendable and exploitable, which has received positive feedback from students.
