Recursos tecnológicos no ensino de conceitos matemáticos: uma análise de livros didáticos do ensino médio

Abstract

The use of technological resources, in particular calculator and computer, in teaching mathematical concepts, has been much discussed today, because its use allows different approach related to a particular concept, for example, the visual approach. In this perspective, this research aims to investigate whether and how the textbook chosen by teachers of high school math schools in the state system of the municipality of Itaqui-RS propose the use of technological resources in teaching mathematical concepts. For this, we carried out a documentary analysis of collections of textbooks used by schools, using as the theoretical research of Borba and Penteado (2010), Allevato (2005), among others. From the analysis we found that the three collections analyzed, only C1, presents activities that suggest the use of a calculator and software. C2, shows no connection with the use of software activity and only three using the calculator and C3 presents some related to the use of calculator activities and any related software use activity. Is important to make a thorough analysis of the planning of the teacher, because besides the textbook, the teacher uses other references to the preparation of their lessons.
