Recently, the necessity of integrated and comprehensive methodology for STEM (Science, Technology, Engineering and Mathematics) education is growing. In this paper, we propose an educational methodology utilizing the viewpoint of Equivalent Transformation Thinking (ETT) theory which has been proposed by Dr. Kikuya Ichikawa in 1955 as a principle of creativity. Especially, we show that the viewpoint of ETT is very useful not only for new technology invention but also for STEM Education in the sense that it deepens insights of the contents to be learned. Moreover, we suggest that the appropriate combination of the ETT viewpoint and the visual presentation such as animation and simulation by 3-Dimensional Computer Graphics (3DCG) will be more effective in motivating students to study further.
