Abstract

In order to support the development of a modelling competency at the beginning of secondary school, we briefly analyse two problem-situations through the use of the GeoGebra3D software. The first problem results in the conics of Apollonius, while the second raises a few considerations on beehives. Our proposal aims to demonstrate the effect of instrumented modelling on preliminary conceptions while considering the coordination of involved operators, representation systems used, and control structures employed in the student-milieu interactions.
