Langbeheim, Elon – Journal of Chemical Education, 2020
Excluded-volume interactions are ubiquitous to modeling the average size of polymers in solution. This paper shows how simulations can be used by students to explore the emergence of mathematical scaling relations from excluded-volume interactions. Simulations provide robust visual representations of the system, and can be used to investigate a…

Araújo, J. L.; Morais, C.; Paiva, J. C. – Chemistry Education Research and Practice, 2022
The active participation of citizens in scientific research, through citizen science, has been proven successful. However, knowledge on the potential of citizen science within formal chemistry learning, at the conceptual and procedural levels, remains insufficiently explored. We developed a citizen science project -- PVC: Perceiving the Value of…

de Waard, Esther F.; Prins, Gjalt T.; van Joolingen, Wouter R. – Chemistry Education Research and Practice, 2020
Sustainability has become a prominent theme in society and can be considered as an integral part of scientific citizenship. This study investigates to what extent the production, use and re-use of (bio)plastics initiates students' reasoning and to identify the kind of content knowledge students put forward. The structure of students' arguments was…
