A EXPLORAÇÃO TÁTIL DE REPRESENTAÇÕES GEOMÉTRICAS PRODUZIDAS COM A CANETA 3D: UMA FERRAMENTA PARA O ENSINO DE ESTUDANTES CEGOS

Abstract

This thesis presents a research that has as objective investigate the using of a 3D pen in the production of embossed materials to allow the access to geometric representations by blind students through tactile exploration. The lack of vision doesn’t affect the cognitive development of students with visual impairment, which makes it necessary to explore other senses that enable the acquisition of knowledge (VIGOTSKI, 2011). The use of tools and resources that allow the tactile exploration of representations has been explored for the production of inclusive materials in math classes (3DOODLER, 2018). This research has a qualitative and exploratory approach and observes, in the quest to observe impressions shared by blind students and education professionals through the exploration of tactile materials produced with the 3D pen and through surveys (GIL, 2008). The tactile exploration of the embossed representations built with the 3D pen allow the access to contents, the recognition of mathematical properties and the concepts formation, bringing benefits in the teaching-learning process of blind students. Therefore, presents the 3D pen as a possible auxiliary tool in the production of inclusive activities in math classes.
