Producción de enunciados de problemas aritméticos de tipo aditivo con números naturales en lengua de señas colombiana y en español escrito con estudiantes sordos de tercero de primaria

Abstract

This document presents the deaf community as well as the hearing community, to train deaf and hearing teachers who teach arithmetic problems to deaf students at school. The colombian sign language (LSC) as the first language of the deaf community. Sign language is presented as a three-dimensional space (3D) that contains the expression of the face, body and hand, contains three fundamental aspects are "situational spaces, questions with questions and mathematical concepts." Written spanish (EE) as the second language of the deaf community. It presents the different systems of representations through written spanish, of which the students express themselves in writing of the symbols, drawings, words known through the LSC. The instruments of the activities appropriate to the hypothetical learning trajectory (THA) for the deaf students are realized, by complements the hypotheses of the LSC and EE, and the implementation of this trajectory is analysed to the deaf students are expressed with the production of enunciation of the arithmetic problems of additive type (PATA) in LSC and EE. The real learning trajectory (TRA) presents the results: 1. All the students did not write in EE, the recourse to mathematical representations and icons predominated to enunciate the problems of the additive type. 2. All the students expressed in written form in different representations, only one level will be achieved by means of these students, since the drawings were manifested in symbols. 3. In written expression with numbering systems, the students achieved the last two levels, because the students registered the writing in numbers along with the count in LSC. 4. The students express in LSC in the situational spaces of the arithmetic problems, but they do not express with LSC of the questions. And in LSC they express mathematical concepts such as numbers in LSC, LSC counting uses manual configuration, orientation and location only with body hand expression.
