Abstract

This paper presents a finding in an ongoing PhD project revealing that 10-13 year-old students can work with the interplay between original mathematical sources and GeoGebra in ways that support the development of their reasoning competency. The study focuses on how to use the dynamic geometry environments in GeoGebra in combination with original sources with a geometrical content. This finding relates to the fact that Euclidian geometry is embedded in the way GeoGebra is constructed and how this can affect the students’ opportunities and challenges when they are engaged
in reasoning and proving activities. Two empirical examples involving sixth-grade students working with the interplay between Euclid’s proposition 6 and 7, book IV and GeoGebra are analyzed using the concept of reasoning competency and Sfard’s theory of discourses.
