Acta Didactica Napocensia Vol. 3, No. 2 (2010) pp. 59–66
In this article we describe long-standing user interface issues with Dynamic Geometry Software and common approaches to address them. We describe first prototypes of multi-touch-capable DGS. We also give some hints on the educational benefits of...
International Journal for Technology in Mathematics Education Vol. 20, No. 1 (2013) pp. 3–8
In this article we present an activity theory based framework that can capture the complex situations that arise when modern technology like multi-touch devices are introduced in classroom situations. As these devices are able to cover more...
Acta Didactica Napocensia Vol. 3, No. 2 (2010) pp. 67–78
In this article we demonstrate how the combination of a system for dynamic geometry with a freely programmable scripting environment can be advantageously used in teaching and research. We explain the reasons behind various design decisions that...

International Journal for Technology in Mathematics Education Vol. 22, No. 4 (2015) pp. 179–185
Dynamic Geometry Software (DGS) is a powerful tool which enables students to move geometric objects interactively. Through experimental simulations with DGS, mathematical facts and background mechanisms are accessible to students. However,...
