Mathematical communication competency in a setting with GeoGebra

The core of mathematical communication competency is the ability to interpret others and the ability to express oneself mathematically. This paper examines the activation of this competency and its interplay with digital technologies in an 8thgrade classroom (age 14–16), focusing on two students’ interaction with GeoGebra. The aim is to investigate and discuss the stated interplay from two different lenses: discourse and instrumental genesis. The lenses bring different perspectives. On the one hand, the results show that using GeoGebra increases the complexity of students’ mathematical communication because the students need to switch between
discourses. On the other hand, to support communication competency, GeoGebra must be an instrument for the students.
