Live teaching can provide students with a rich display of learning resources and the pleasure of learning that they can easily feel in the online learning environment of offline traditional classrooms, thereby enhancing their motivation to learn. Therefore, perceived pleasure has a positive impact on college students’ willingness to use live teaching. This paper uses structural equation modeling to quantitatively describe the causal relationship between variables and the impact of variables on live teaching usage behavior. Taking the use of smart education platform as an example, its purpose is to combine the technology acceptance model and the unified model of technology acceptance and use, and use structural equation modeling to better understand and predict the impact of desire factors on the use behavior of higher vocational college students in the system. Moreover, students generally recognize the online teaching method and hope to combine online teaching with offline teaching.
