Matemática para cegos: uma possibilidade no ensino de polinômios

Abstract

This research aims to recognize the capacities and limitations of the teacher's action having as objective the allocation of concepts of polynomials by blind students in the regular classroom. To do so, it presents a legislative history on the subject and discussions about the role of the teacher in relation to inclusion classrooms. Unusual methods, instruments of communication and writing are presented, all of them can be used by visually impaired people. There are also different concrete materials currently commercialized that are used in the teachinglearning process of certain mathematical contents and they can be used with blind students. We present some teachers’ reports regarding the work with manageable materials in the teaching process of blind students, they were registered by means of works and researches of the area and also a report by the undergraduate student about the organization of the education of notions of statistics for visually impaired people put into a regular classroom. This work is accomplished by describing the elaboration and analysis of a teaching sequence for the development of algebraic notions related to polynomials, as well as their operations, using a specially-made material for this stage. This research highlights the need to understand the characteristics of visually impaired students, the use of instruments that enhance their learning, as well as the role of the teacher in relation to the organization of teaching, particularly in the knowledge of the teacher about the material in use and the didactic with the class.
