The Arduino microcontroller enables ordinary people to perform professional tasks that only traditional engineering professionals could perform. Recently, several educational cases have been applied to primary and secondary schools, which is a desirable attempt to popularize engineering education. This study meta-analyzed the effects of Arduino-based education in primary and secondary schools in Korea from the perspective of engineering education. Accordingly, 16 academic journals and dissertations were selected that verified educational effects by Arduino-based education to primary and secondary students in Korea, and 31 effect sizes were confirmed. According to the results of this study, the overall average effect size was 0.656, which confirmed that Arduino-based education had a positive educational effect. Furthermore, this study calculated the effect size as measured by categorical and continuous variables such as school level, the inclusion of curriculum, giftedness, publication status, the programming language used, publication year, number of sessions, and number of students. Implications were suggested from the perspective of engineering education. This study is meaningful because it suggests the application of Arduino to primary and secondary schools in engineering education by confirming the positive educational effect of Arduino-based education.
