When analyzing what has changed in the geometry scenario with the advent of dynamic geometry systems we can notice a transition from the traditional paper-and-pencil environment with the classical construction tools to a virtual graphic space made of a computer screen, special graphical tools available within the software and the possibility of dragging objects on the screen, interacting with the constructions. In this paper we analyze ways in which students drag points on the screen as they generate conjectures in open problem situations in Euclidean Geometry.

Abstract

When analyzing what has changed in the geometry scenario with the advent of dynamic geometry systems we can notice a transition from the traditional paper-and-pencil environment with the classical construction tools to a virtual graphic space made of a computer screen, special graphical tools available within the software and the possibility of dragging objects on the screen, interacting with the constructions. In this paper we analyze ways in which students drag points on the screen as they generate conjectures in open problem situations in Euclidean Geometry.
