| dc.description.abstract | A partir de ejemplos pro-venientes de un proyecto que inició a finales de los años 1970, y que ha sido ampliamente experimentado en la escuela primaria y los primeros cursos de secundaria, me propongo ilustrar cómo es posible moverse desde la construcción argumentativa de conceptos geométri-cos en campos de experiencia adecuados (en particular, en el campo de experiencia de las sombras solares) hacia el desarrollo de las competencias argumentativas necesarias para validar conjeturas en geometría y para aproximarse a teoremas de la geometría tridimensional. La producción y validación argumentativa de hipótesis relacionadas con ciertos fenómenos y situaciones espaciales proveen oportunidades a los estudiantes tanto para desarrollar la conceptualización en el campo de la geometría como para tener un acercamiento al razonamiento hipotético (“si... entonces...”), al enca-denamiento deductivo de proposiciones, etcétera. La mayoría de los ejemplos tienen que ver con situaciones tridimensionales de sombras producidas por el sol | spa |
| dc.description.abstractenglish | The aim of this paper is to illustrate, through examples taken from a Project widely experimented in primary and lower secondary school since the end of the seventieths, how it is pos-sible to move from the argumentative construction of geometrical concepts in suitable fields of experience (in particular, the field of experience of sun shadows) to the development of students' argumentative skills that are needed to validate conjectures in geometry, and to their approach to 3-D geometry theorems. Pro-duction and argumentative validation of hypotheses concerning suitable space situations and phenomena provide students with the opportunity of both deve-loping conceptualization in the field of geometry, and approaching hypothetical reasoning (“if... then...”), de-ductive enchaining of propositions, etc. Most examples will deal with 3D-situations concerning sun shadows | eng |
