Application and Research of Virtual Reality Technology Based on Big Data in College Teaching Field

Virtual reality technology (VR for short) is a new technology combining computer technology and simulation technology, which uses computers to generate a simulation environment and immerse users in the environment. Virtual reality technology can use virtual simulation software to model, build virtual instruments and scenes, and enable users to learn and operate simulation experiments in virtual scenes. Big data technology has been applied in various fields, and it can also be applied to education. Using educational data mining technology and learning analysis technology, the corresponding model in the field of education is constructed, and the special relationship between the acquired educational data is explored. This paper introduces the concept of virtual reality technology in detail, and discusses the application of virtual reality technology in college teaching and the significance of modern educational technology in college teaching.
