A solução de situações que envolvem o conceito de fração por formandos do curso de licenciatura em Matemática da UFT

Abstract

The present work deals with the view of authors who report the difficulties of teachers and students in the teaching and learning of fractions in the initial series, and explana about the theory of records of semiotic representations of the author Duval (2009). It aims to investigate how teachers trained at the Federal University of Tocantins in the degree course in Mathematics of the period 2018/2 in the campus of Araguaína-TO mobilize the records of representations in the meanings of fractions and seeks to contribute with the knowledge of the scope of the fractional meanings. It is a qualitative study whose methodology used to obtain the data and information was through a questionnaire that aims to understand the particularity of the responses of the participants addressed to the means representative of the meanings of the fractions. Five subjects participated in this research, who answered the sequence of activities, organized into tasks dealing with five meanings of the fractions (part-whole, number, measure, quotient and multiplicative operator). The results show that the respondents operate satisfactory knowledge about the records of semiotic representations.
