The need to extend CBL courses over longer periods - a test case on a CBL course on IoT

We report on our gained insights from the development of a challenge-based learning (CBL) line focusing on entrepreneurship and internet of things (IoT) technology. We observe that student engagement and quality of project work and learning has significantly been improved when the original one-course CBL experience has spread out over three consecutive courses. We further suggest that for the case of multi- and interdisciplinary learning lines, focus on the different disciplines in different courses, encourages students to engage in aspects of CBL outside their own discipline, hence better fulfilling the design goal of true multidisciplinary learning.
