Os níveis de desenvolvimento do pensamento geométrico de estudantes com perdas auditivas: uma pesquisa exploratória em uma escola de inclusão de pessoas com necessidades especiais em Maceió

Abstract

Our general objective in this dissertation is to investigate the levels of development of geometric thought presented by students of the 2nd grade of high school with hearing loss, from a public school in Maceió / AL.It is an exploratory qualitative research. This study is based on van Hiele's theory of geometry learning, on Borges and Nogueira's considerations on deaf learning of mathematics. For data collection we used interviews and questionnaires with the research subjects (students, teacher and Libras interpreter).For data analysis, we used the criteria established in the van Hiele theory regarding the possible results obtained, through the resolution of the tests provided for in this theory, and the interpretation of the responses of the research subjects collected in interviews through Laurence's Content Analysis Bardin.We obtained the following results: (1) the students subject to the research presented a learning below the expected in relation to the development of geometric thinking, all of them falling into level 1, that is, in the first level of the scale from 1 to 5; (2) the teacher visibly showed unpreparedness to deal with students with hearing loss and (3) the interpreters and the teacher himself showed low expectations regarding the students' learning.As for the educational product, the result of this dissertation, we opted for the elaboration of a manual to assess the levels of geometric thinking of students with hearing loss for teachers of basic education.
