Um estudo sobre a resolução de problemas matemáticos propostos em língua brasileira de sinais e em língua portuguesa escrita

Abstract

This work seeks to analyze how the translation in video format recorded for the Libras of mathematical problems can contribute to their interpretation by deaf students who use Libras. The path chosen for the development of this work has a qualitative and exploratory character with a case study which allowed to investigate the contributions made possible by the use of the Brazilian Sign Language in Problem Solving and to understand the main difficulties of deaf students in problem solving activities without the use of Libras. Data were collected through a semi structured interview with 3 (three) deaf students, from the 9th year of the Instituto Londrinense de Educação de Surdos (ILES); And also, through the application of a test with mathematical problems for the 3 (three) deaf students, in two phases: in the first, the student will receive the test in Portuguese Language and, in the second, in Libras, whose objective was to discover the contributions of the Brazilian Sign Language in the interpretation of mathematical problems by deaf students. The results presented indicate it is indifferent whether the problem is proposed in Portuguese or in Libras, since the participants presented difficulties in the mathematical interpretation of the problem, as well as in the related mathematical content. Therefore, it is necessary a mathematics teaching appropriate to this public and whose teaching methodology is based on visualization and mathematical experimentation.
