Considerations on the imagery in Spanish Sistema Diédrico.

Abstract

The article highlights the classic mistake of thinking processes obviate the task of structuring the student’s spatial thinking and how this fact contributes to the saturation of theoretical content that has characterized the graphic-geometric representation in the field of descriptive geometry during the last century. Research provides a diagnosis of the paradoxical situation of a subject which, despite being based on images yields to the orthodoxy of propositional analysis ending in a complete axiomatization of graph-geometric representation. In this area, visual thinking is disallowing direct accessibility as the interpretation of spatial relationships. From advances in cognitive science about mental imagery are counter points to the possibility of stagnation in the projective space concept to contribute to greater spatial interaction. In this sense, values the contribution of Anglo-Saxon direct method as initiator of deductive-Cartesian apparatus in projective rationalization.
