Models and modelling in STEM education from a mathematization perspective

Speaker: Mathilde Kjær Pedersen, IND

Abstract: The use of models and modelling is fundamental in science, technology, and mathematics disciplines both in research and education, but their interpretation and application can vary significantly across different STEM fields. This study investigates the conceptualization of models and modelling across biology, chemistry, and physics in the Danish upper secondary school system. By examining these concepts through three lenses—communication, mathematization, and datafication—the research identifies disciplinary overlaps and differences, aiming to support interdisciplinary STEM education that involve models and modelling. As one out of three postdocs on the study, I focus on the mathematization of models and modelling in upper secondary physics and chemistry, where algebraic and statistical methods are used to describe covariant relationships. The study collaborates with teachers to design and test teaching activities that integrate models and modelling across these subjects. The findings contribute both to STEM education research and to practical teaching strategies, enhancing the development of students’ modelling competencies.
