Abstract
Computational and design thinking are orthogonal and complementary ways of thinking, which are fundamental for nowadays’ learners and yet taught in isolation. Teachers’ understanding of them can be a barrier to their introduction. This paper reports on an intervention for primary- and secondary-school teachers, introducing them to both forms of thinking through hands-on laboratories, revolving around the IoTgo game-based toolkit. Teachers’ ideas of computational and design thinking were investigated with a questionnaire before and after the intervention. Their answers suggest that the intervention was effective and indicate future work related to computational and design thinking.
