Propuesta didáctica apoyada con geogebra para la enseñanza del teorema de Pitágoras en grado noveno

Abstract

The development of the competences and standards that have to do with the spatial and geometric thinking, that are worked within the contents of the geometry subject in the educational institutions Instituto Tecnico Central La Salle and, Fundación Colegio Mayor San Bartolome institutions where the development of the present research, faces a teaching and didactic practice with traditional approach and little support of new technologies such as dynamic educational software, situation that allowed to pose as objective, the design of a sequence of activities based on the levels and phases of geometric reasoning of Van Hiele through the use of educational software GeoGebra with ninth grade students, specifically with the thematic of the Pythagorean theorem. For the development of the investigation there was elaborated initially a diagnostic initial test to take as a modal the level of geometric reasoning, according to the model of They Go It freezes from which there was designed and realized the sequence of activities supported with the educational software GeoGebra that simultaneously took as a backbone the phases of learning of the model previously mentioned; once finished the implementation of the offer, a final test was applied, so that a modal of the advance was had in the level of reasoning of the students once they took part in the execution of the didactic offer and to be able like that to analyze, discuss and conclude relevant aspects to strengthen the didactics of the geometry
