Entendimento de futuros professores de matemática sobre os conceitos de função e equação

Abstract

This work aims to investigate the understanding of future mathematics teachers about the concepts of function and of equation. The theoretical framework was based on historical aspects of Algebra, especially those related to function and equation, as well as recommendations for its teaching and initial formation of the Mathematics teacher. The research is characterized as qualitative and the discursive textual analysis was used as a tool for the organization, understanding and analysis of the data.The participants of the research were the final students of the Mathematics Degree course, from the Universidade Tecnológica Federal do Paraná, Campus Cornélio Procópio. The instrument used for the data collection was a semi-structured interview. The course of the research made possible the reflection and discussion around the researched topic. The results indicated, in general, that the students interviewed have difficulties in relation to the concepts of functions and equations, related to the experiences during the Basic Education. The content approach shows that in Higher Education, functions and equations are little explored from the perspective of teaching.
