Design thinking dispositions are essential for students to understand why design thinking knowledge should be applied to perform specific tasks. However, few studies are focused on teaching design thinking dispositions. This study proposes a conceptual model that supports teaching design thinking dispositions to address this gap. The model was instantiated in an undergraduate course. Students' reflections about the course were collected to evaluate the model. The use of the model is also demonstrated by considering different teaching scenarios. This study contributes to better teaching and learning design thinking dispositions based on a unique model that helps educators organize their design thinking courses. The study also derives some implications for educators. While teaching design thinking knowledge and skills is essential, developing students' design thinking dispositions is equally essential.
