Mathematical thinking competency in learning situations involving DGS and CAS

Speaker:

Mathilde Kjær Pedersen, PhD-student at Aarhus University (currently visiting IND) 

Abstract:

The mathematical thinking competency is one out of eight mathematical competencies of the Danish competency framework (KOM). KOM is a broad framework describing what it means to master mathematics across mathematical content and level and focusses on the cognitive processes of actively doing mathematics. Since the millennium, KOM has influenced mathematics curricula in Denmark from primary to upper secondary school. At the same time, the use of digital technologies has entered the classrooms of teaching and learning mathematics. In Danish upper secondary school, the most applied digital tools are Computer Algebra Systems (CAS), such as TI-Nspire and Maple and Dynamic Geometry Systems (DGS). In this talk, I present my PhD project, in which I investigate the relation between students’ use of digital technologies in learning situations of differential calculus involving the mathematical thinking competency of the KOM framework. Through design research, the aim is to develop a theoretical framework describing the interplay between students’ use of digital technologies and their mathematical thinking competency. To do so, I make use of the research practice Networking of Theories, where I suggest networking the mathematical thinking competency with the perspectives of instrumental genesis and conceptual fields.
