A functional game combining game elements such as fun and pleasure of a game and other additional elements has attracted attention. Compared to various functional games, educational games are not getting attention. In this paper, we tried to solve the problem that the educational contents and the fun were separated and the learner s immersion was difficult. In this paper, we propose an example of educational game contents production that can maximize learner s immersion through participation of learner s game in virtual reality. Through educational game contents that utilize VR, learners experience real-world experiences by participating in games in virtual reality, and they actively motivate learning through sense of accomplishment while clearing games. The reality of VR is effective to extrude user s immersion. In this paper, we tried to maximize learners immersion by using them in educational games. In addition, we wanted to help research on educational games in the future by directly producing educational games using VR.
