Instrumental genesis concerning scales and scaling in a dynamic mathematics software environment

Résumé

It is recognized that the process in which an artefact becomes an instrument for a user, denoted as instrumental genesis, is a complex process. The aim of this paper is to identify elements of the process of instrumental genesis when students are dealing with scales and scaling issues in a dynamic mathematics software environment. This study involves four upper secondary school teachers and their classes. By observing the students' instrumented techniques while working with tasks designed with a hypothetical instrumental genesis in mind, some key elements are identified.
