Application of AR Three-Dimensional Teaching Materials Based on Big Data

This paper proposes the construction of AR three-dimensional teaching materials to build immersive learning environment at present. The AR three-dimensional teaching material micro-course is developed. An intelligent learning test database is established based on big data and online educational resources. The system includes multimedia teaching resource sharing, material bank, question bank management, learning forum and auxiliary modules. Using Unity3D, Easy AR and other technologies, we establish a 3D entity modeling platform, and on this basis we develop a mobile phone AR multimedia courseware terminal. The 3D presentation of 2D content in traditional textbooks is realized. In particular, the three-dimensional display of secondary tilt measurement is studied. Various means of applying AR 3D materials to middle school mathematics classroom show that the system is a medium carrier for building personalized and immersive. This system is helpful to improve the knowledge conversion rate and students' interest in learning, and has good value and significance.
