Create a dynamic teaching atmosphere for distance learning with secure virtual classroom

As the new crown epidemic has gradually become a normalized disease similar to the flu, people are paying more and more attention to remote work and learning. Companies such as meta have spotted the development of the remote social track, and positioned the overall development direction of the company as the research and development of the metaverse virtual space. During the epidemic, the school's population base was large, and the students' demand for distance learning was also large. In the current distance teaching, students' sense of participation, concentration, and learning effect were poor. With meta company's all-round research on virtual technology, VR and other technologies are rapidly being applied in various industries. Among them, the application of VR technology to the creation of virtual classrooms has become a research hotspot in academia, but the probability of exposure of students' personal information to virtual classrooms how to ensure the security of students' information while carrying out efficient teaching in virtual classrooms is the focus of this paper. This paper first introduces VR and blockchain technology and their corresponding applications, and then uses a questionnaire to obtain the current information security issues and teaching atmosphere of distance learning, and summarizes the current distance learning for students and teachers according to the questionnaire. needs and actual problems. Finally, combined with the characteristics of VR virtual technology, a virtual classroom is designed to solve the current problems of distance learning. After a simulation test, it was found that the distance teaching classroom using virtual reality technology can achieve the same or even better teaching effect than the traditional offline classroom.
