In recent years, due to the impact of global COVID-19 pandemic, some foreign students are unable to study in China normally. Based on this, the college physics experiment teaching center of SWUST has explored a smart teaching mode of integration of reality platform, virtual platform and interactive platform by combining various modern information methods, such as online video teaching, online teacher-student interaction, and virtual experiments. The application of the model solves the problem that foreign students cannot finish offline experimental courses normally, and help them to have a deeper and more comprehensive understanding of physical nature of the experimental content.
