Design-Based Research (DBR) has recently received a significant amount of attention in the educational research literature of the 21st century. This work analyses the understanding of DBR as the research methodology, why, and how it can be applied in educational research to bring a practical outcome and improve educational practices. Besides, this work reflects on a step-by-step implementation of the Hands-on Instructional Model (HIM) designed to enhance the development of chemistry learners’ curiosity and problem-solving skills. Also, it gives a detailed description of the two prototypes of the first alteration cycle. A sample of 169 Senior Three chemistry students was purposively selected from three science classes to participate in this study. Design-based research was recommended as a viable research methodology to educational researchers for their lifetime professional contribution to the research in the education field and to bridge the gap between theory and practice in educational contexts.
