This study explores the integration of drone technology into STEM education through the development and evaluation of the Drone Technology Enabled STEM Curriculum (DTESC). Grounded in "dronagogy", a pedagogical framework that utilizes drones to enhance learning, DTESC effectively incorporates drone technology within science, mathematics, technology, and the humanities. The curriculum is structured to progress from multidisciplinary exploration to interdisciplinary integration, ultimately culminating in transdisciplinary applications. Sixteen Grade 9-10 students from a secondary school in Hong Kong participated in the study, engaging in activities such as designing drone-assisted water sampling systems and formulating entrepreneurial proposals for future applications. Employing mixed research methods, the study assessed the curriculum's impact across cognitive, psychomotor, and affective learning domains. Results indicated high levels of student engagement and satisfaction, alongside significant improvements in psychomotor and affective skills. However, enhancements in cognitive learning outcomes, particularly in mathematics and programming, are necessary. This research offers valuable insights into the implementation of dronagogy to foster cross-disciplinary STEM education.
