In mei 2022 maakte de Event Horizon Telescoop (EHT) het eerste beeld van het zwarte gat in het centrum van ons sterrenstelsel, de Melkweg. Het zwarte gat heet Sagittarius A*. Het heeft deze naam gekregen omdat het zich bevindt op het deel aan de hemel waar het sterrenbeeld Boogschutter staat. In deze …

Students often struggle with constructing models of system behaviour, particularly in open modelling tasks where there is no single correct answer. The challenge lies in providing effective support that helps students develop high quality models while maintaining their autonomy in the modelling process. …

Understanding the behaviour of parallel circuits is challenging for many students. In this paper, we present a lesson designed to support students in learning about parallel circuits by constructing a qualitative representation. Qualitative representations are non-numerical models that focus on causal …

This paper presents three lesson activities for upper secondary and higher education that focus on learning by constructing an interactive qualitative representation. By constructing the representation learners learn domain knowledge as well as general system thinking skills. The learning goals and the …
