Challenge-based learning is becoming an important learning and teaching strategy at Eindhoven University of Technology (TU/e, 2018). During challenge-based learning, students work in multi-disciplinary groups on open-ended and real-life challenges that are provided by stakeholders in the field of engineering (Membrillo-Hernández et al., 2019; Rosén et al., 2018). Teachers are expected to work as coaches, who support and guide the learning process of the students. Both ‘traditional’ teacher-based instruction (e.g. in lectures) and challenge-based learning (and coaching) are currently practiced at Eindhoven University of Technology.
