A resolução de problemas: uma metodologia ativa no ensino de matemática para a construção dos conteúdos de "Potenciação e radiciação" com alunos do ensino fundamental

Abstract

The present work aims to utilizate the Metodology of Mathematics Teaching-LearningEvaluation through Problem Solving in order to promote an active learning, providing to the student the opportunity of to be a constructor of the own knowledge. For this, a series of generator problems, was developed with students of the final years of the Elementary School to the construction of concepts of exponentiation and root extraction. The methods used for the collect of data were: interviews, documental analysis and participant observation. The data were recorded by: photos, audio recordings, field journal of the teacher and the generators problems solved by the groups, that were organized in portfolios of Problem Solving. By the materials that were collected, the resolution of six problems applied to 15 students of the 7th year were analyzed. Based in the development of the activities it was possible infer that different strategies were used, besides there was a search for previous knowledge to solve the problems and, even, it was possible to identify that teacher and student taken on new roles and consubstantially the Math class became new. This way, this work shows itself like a possibility to the teaching of exponentiation and root extraction, that can contribute to construction actively of the knowledge of the students and to the professional enhancement of others teachers.
