The aim of this research study is to investigate and evaluate the effectiveness of innovative use of an open-source digital technology, Arduino, which is an information and communications technology (ICT) tool for practical work in physics in the senior secondary curriculum. The study also seeks to ascertain factors affecting the effective use of the technology in students’ learning of physics with a view to informing possible extensive use of the Arduino technology in senior secondary science education and its application to Science, Technology, Engineering, and Mathematics (STEM) education. The importance of harnessing ICT in education is well recognized in the education arena. Educators have viewed ICT as an enabling tool for higher levels of analysis to take place in science teaching and learning. However, the use of technology does not guarantee meaningful and effective learning. What is crucial is the transformative, appropriate use of ICT to enhance students’ learning. In this regard, proper integration of ICT into the curriculum, or even across disciplines in the context of STEM education, for meaningful study is an area of concern. While ICT integration has been advocated for many years in the senior secondary physics curriculum in Hong Kong, there remains a gap in its holistic integration into the curriculum. This study demonstrates successful development of seven Arduino-based experiments and an entire set of courseware that covers a wide range of experiments in the topic of “mechanics” in the senior secondary physics curriculum. Design-based research (DBR) methodology is adopted in the development, which is characterized by rounds of systematic iteration, feedback gathering, and modification. The final outputs are encouraging for performing the series of experiments in “mechanics”. The study bridges the gap between theoretical framework and practical application in an authentic setting, and it informs of the suitability of DBR in developing ICT tools for
