Aprendendo por meio da análise de erros : uma investigação sobre as operações com frações no estudo da função afim

Abstract

This paper proposes to investigate the difficulties presented by the students of the 9th year of elementary school in activities that involve the operations with fractions applied in a related function. The study is based on a qualitative approach and the idea that the analysis of students' written production can be worked as a teaching methodology (CURY, 2008). Data collection was performed through three questionnaires and a review activity applied to the students of a school in the interior of the state of Sergipe. A second approach was made around error analysis as a teaching methodology, by presenting and discussing with students the mistakes made by them in Questionnaire 1, trying to make them understand the reasoning that led them to make such mistakes, and from this overcome their difficulties, which was analyzed in the following questionnaires.
