LARIOS OSORIO, Víctor. La rigidez geométrica y la preferencia de propiedades geométricas en un ambiente de geometría dinámica en el nivel medio. Relime [online]. 2006, vol.9, n.3, pp. 361-382. ISSN 1665-2436.

The Dynamic Geometry offers the possibility of an approximation to the study of Geometry that permits the dynamic manipulation of the geometric objects, opening thus possibilities that before were not available for the students of the medium level. Nevertheless, some cognitive phenomena continue presents, like the geometric inflexibility and the fact to prefer some visually evident geometric properties over other, and in fact, they are influenced by the perception that the geometric objects they have due mainly to the dynamic characteristic of the software and to the dragging operation. For that reason the research was carried out to deepen on this issue and, considering the Theory Figural Concepts, to study the presence and sign of phenomena as these in a Dynamic Geometry environment.

Keywords : Dynamic geometry; geometric inflexibility; figural concepts.
