O ensino de geometria plana para uma aluna com surdocegueira no contexto escolar inclusivo

Abstract

This research intends to analyses the contributions activities with adapted manipulable materials in formulation of plane geometry concepts by students with deafblindness. For this, an applied research with qualitative descriptive approach, characterizing this as a case study was developed. The study happened in a class of 9th year of Elementary School at a state education school, in Guarapuava - PR. In order to actualize the research, the mathematics teaching, the use of manipulable materials and concepts elaboration, school inclusion, deafblindness and its teaching and learning process were substantiated. Initially, the school pedagogue, the Math professor, the Libras interpreter and the student with deafblindness were interviewed. By the interviews, the school inclusive context and how the teaching and learning process is made were understood, principally, in Mathematics. After interviews step, an initial test, composed by fourteen questions, was aplied for all students in the class. After the analyses of the test, were selected some activities involving plane geometry and the needed material to the application of this activities was made. There were, also, adaptations in the material, in order to meet the needs of the student with deafblindness. In the next step, there was the pedagogical intervention, in which all students participated developing activities using the same adapted material made for the student with deafblindness, therefore, there wasn’t distinctions between the activities and materials used by the student with deafblindness and the other students. This material was denominated “Adapted Manipulable Materials Kit”, that is composed by a collection of activities selected by the researcher. The steps of concepts formation of Galperin (2009a) were the base to the pedagogical intervention, that demonstrate great progress of the students in the plane geometry concepts formulation. By the application of final test, after the pedagogical intervention, were found positive results, since the student with deafblindness had an initial school achievement of 53%, passing to 92% in the final test. The performance of the class went from 54% in the initial test to 81% in the final test, after the pedagogical intervention. The research results evidence that teaching strategies with well-designed goals contribute to that students, with deficiency or not, appropriate the scholar content, in this case, they elaborated mathematical concepts.
