To enable to cultivate students the literacy of aesthetics and technology in the engineering design field. We developed a Science, Technology, Engineering, Arts and Mathematics (STEAM) oriented Maker curriculum centered on designing a high-speed stylish racing car. After developing the curriculum, we analyzed the learning outcomes of two groups of students (high school students and design college students) to assess their competencies. There were significant differences in creativity and learning outcomes. The findings of the present study would benefit the future design, development, and implementation of STEAM curricula.
