DEAFBLINDNESS AND EVERYDAY MATHEMATICS: AN ETHNOMATHEMATICAL VISION
This work aims to expand the knowledge of mathematics for people with disabilities, specifically, deafblind people. For this, we find the theory of Ethnomathematics which elucidates the use of mathematics in the individual's daily life in a cultural way. The purpose of the conjecture was defined to show that the Deafblind Community is made up of people with different ways of communicating who share the same culture. The idea is to show that these people are recognized for cultural and linguistic reasons and that mathematics is part of this culture. For many years, teaching people with deafblindness went through a long process of experimentation. Even knowing about the particularity of each person with a disability, through the narrative of a person with deafblindness, the objective is to compare the teaching and learning of mathematics, with few technological resources and what is the functionality in their lives today. The Ethnomathematics Program proposes to approach teaching and learning starting from the culture from which mathematical knowledge emerges that one wishes to understand beyond the hegemonic mathematical knowledge. The methodology used for the research is ethnomethodology, based on a semi-structured interview with resources from narratives and experiences of this individual. To think, currently, the mathematics taught to people with deafblindness based on the parameters of Special Education, are they in fact of a functional or methodological nature? With theoretical data and field analysis, it is understood that mathematics is a link capable of interconnecting special education target audience students, through forms of communication, pedagogical proposals and assistive technology resources.
