Análise de erros na resolução de questões da OBMEP: uma proposta de utilização do GeoGebra como recurso didático

Abstract

This dissertation has as its guiding question: What are the contributions of error analysis and GeoGebra to the appropriation / differentiation of the perimeter and area quantities? To answer the question, an analysis of errors made by students was initially performed on the resolutions of modified OBMEP questions, according to the classification proposed by Radatz (1979). From the analysis, strategies were proposed to solve other questions adapted from OBMEP with the support of GeoGebra software. The research was carried out at the João XXIII Basic Education State School, in the city of São João do Polêsine - RS and had the participation of twelve students from 7th, 8th and 9th grades of middle school. Based on the answers of the initial and final questionnaires, the summary table and the analysis of the question resolutions, it was found that the error analysis and GeoGebra contributed to the development of the appropriation and differentiation of the perimeter and area quantities in the group of students.
