In the study of college physics, experiment is the source of students' discovery and exploration of problems, which plays a crucial role in college physics and is also the focus of physics teaching. This paper mainly studies how to use B/S architecture and MVC design pattern according to the characteristics of college physics teaching, including user management and system function modules. In order to illustrate the role of virtual experiment scene based College Physics Teaching Platform in college physics learning, a virtual physics laboratory teaching platform based on B/S three-tier structure system and MVC mode is constructed by using Java, VRML and flash interactive technology. Based on the advantages of virtual technology, this platform starts with the construction of a teaching platform of virtual experiment scene, analyzes students' mastery of university physics experiments before and after the use of it, and then carries out a systematic survey of students' satisfaction, thus obtaining the influence of this teaching platform on university physics learning of college students. The results show that the platform constructed in this paper can help college students better grasp the operation of physical experiments, so as to better understand the relevant knowledge points in college physics learning, and has a good reference value.
