Abstract: The purposes of this study were to develop an engineering design and scientific inquiry education program based on STEAM (Science, Technology, Engineering & Arts, Mathematics) education program and to investigate the effects of STEAM on the interest, self-efficacy and career choices of middle school students. The subjects of the study were 151 first-graders of J middle school in G city. One sample pre-post paired t-test was conducted to measure the students’ interest, self-efficacy and career choices toward STEAM. The results are as follows: First, the STEAM education program based on engineering design and scientific inquiry had statistically significant impact on increasing the interest of the middle school students toward science, mathematics, technology, and engineering. In addition, the program improved the middle school students’ sense of self-efficacy. Second, the program had statistically significant effects on the career choices of the middle school students. Perceptions of fields related to science, math, and technology became more positive, and the proportion of students choosing a future occupation related to science, math, and technology increased as well. The developed program could be effectively utilized in schools to revitalize STEM/STEAM educations; it could most likely engender the development of science technology
talents.
