Análise de erros: uma proposta didática para o ensino das equações do 1°grau

Abstract

This paper aims to present and discuss a didactic proposal for the content of Equation of degree1 considering the error analysis of students of elementary school from the context of situations with balance. According to this research, its objectives was classified as exploratory, and as the survey data was used as a case study. The research had the collaboration of five mathematics teachers from the state public school system who participated in an interview and also investigated conceptions and practices of teachers on the teaching-learning Equation content of 1st degree unknown. When contemplating the answers of the participating teachers, we realized that ignore the error analysis as a teaching methodology even after identifying the same types of errors discussed in this research. We produce a didactic proposal based on situations that work common mistakes in order to develop the student's ability to reason without the use of techniques used in a mechanical way.
