Interpretação de textos matemáticos: dificuldades na resolução de problemas de geometria plana

Abstract

This dissertation is the result of a qualitative research which object of study is to analyze the interpretation of mathematical texts and the difficulties in solving plane geometry problems, from records produced by the researched subjects belonging to two classes of the Technical Course Integrated to High School in the form of Youth and Adults Education of the Federal Institute of Roraima in 2008, a group of Nursing and other of Laboratory. This analysis was conducted in the light of theorists such as Gilles-Gaston Granger and Ludwig Wittgenstein, which made me realize the "difficulties" found in the learning plane geometry, according to the precepts of the PCNs and noted in the analyzed records are given by through the complexity of the languages presented in the classroom, such as natural language and mathematical language. Subjects studied indicate "difficulties" in learning, when faced with the need to translate natural language to mathematical language in order to objectify through writing the solutions to the problems posed. These "difficulties" may lead them to discouragement, the withdrawal and / or truancy of study. For these reasons, I intend with this research find grants that may indicate ways to minimize this problem by encouraging them to study through research, daily reading, so that they are able to learn the math concepts with more ease and pleasure.
