O uso de dobraduras como ferramenta didática no ensino dos poliedros de Platão

Abstract

It is known that Plato's polyhedra is a subject little recognized by students within spatial geometry, but this subject is very interesting because they are associated with the four primordial elements of all material bodies, "fire, air, water and earth". The objective is, therefore, to understand the difficulties established in the teaching and learning processes of Mathematics, with the main focus on Plato's polyhedra using folding as a teaching tool. For this, at first, an observation of the school structure was made and an interview with the teacher of the class that the project was applied to. In the second moment, a questionnaire was applied, and the construction of Plato's polyhedra using folds (origamis), so the students were practicing interdisciplinarity because they were establishing logical reasoning, concentration, group work, among others. In the third moment, with the polyhedra already built, a more in-depth study of these polyhedra was carried out. In a fourth moment, a new questionnaire was carried out with questions of the same level carried out at first on the subject of Plato's polyhedra, at the end, a comparison of these questionnaires was carried out seeking the mathematical difficulties that the students had and whether the use of concrete material was effective for their teaching-learning process
