Uma análise crítica sobre o ensino de área de figuras planas na educação de jovens e adultos: um estudo localizado no município de Angra dos Reis

Abstract

This work is the result of a qualitative and quantitative analysis of the problems encountered in the teaching of plane figures in young and adult education and, even as a present activity in day-to-day lives, it is still a problem. This theme was chosen because of the student’s desires to learn that content, enabling to search where is the origin of the various difficulties encountered by them in calculating areas of plane figures and to get applied in their daily lives. The choice of this teaching modality comes from the challenge of how to work this content with a very heterogeneous group, both in age and in the motivation that led them to attend the classrooms of young and adult education. This fact causes a significant change in the methodology used by the professor in relation to the same applied in regular education. To understand all this process it is necessary to know a little of young and adult education in Brazil, its normative aspects and the historical importance of knowing how to calculate areas of flat figures. Through a questionnaire, we identified the young and adult education professor's profile, how this type of education is administered by the government and how professionals deal with such different student profiles. With this information, together with the analyzes of the questions answered by the students, we conclude that the difficulty of assigning correctly the units of area and length measurements is due to the difficulty of the student to relate the mathematical content learned in school to their daily lives. In some of the issues applied to students we had to allow the use of the calculator due to the difficulty that students have to perform at least one of the four arithmetic operations
