Uso de representaciones semióticas en el aprendizaje de las operaciones de suma y resta de números enteros en una aula con integración de población ciega.

Abstract

This work was made with the purpose to identify the privileged semiotic representation by blind students in the understanding and the meaning structure of integers applying the addition and subtraction operation, applying the ICT as well as a tool to allow the integration of diverge populations. To develop the activities it used five blind people who familiarized with the material representing daily situations which had to do treatments and conversion, taking as math stuff the integers. The Arithmetic way allow to establish relationships within amounts which applies Arith treatments and the communicative moments of ideas or results applies frequently the natural language. The application of variety situations and didactical materials can built clearly the meaning of integers improving the cognitive process, treatment and conversion of the semiotic structure in the property communication’s actions.
