This study developed an unrealistic simulation program that is executed by students' concept and applied it to classes, and investigated how the program affects students' cognitive conflict and conceptual change Based on the results of the investigation, it proposed a class model (US Model), which applies the virtual reality technique to classes. Our result shows that simulation that runs according to misconception is effective in provoking inner conflicts concerning movements that are usually hard to observe. In addition, the use of virtual reality simulation increases students' absorption and induces them concentrate on learning and make active inquiries.
