A MATHEMATICAL VISUALIZATION IN BASIC EDUCATION: from theoretical paths to solving ENEM problems

mathematical visualization, problem solving, ENEM

In the current stage of teaching in Brazil, the configuration of the school curriculum, the methodologies employed, the guiding principles of high school educational practices, are constant fields of intense debate, with the aim that the school can perform consistently and appropriately the its social and citizenship role. In this scenario, the teaching and learning of Mathematics, especially with regard to the curriculum and teaching methodologies, is routinely the subject of studies and investigations, in view of the problem that insistently plagues the processes of learning and teaching this science, namely: mathematics teaching cast in an algebraized practice. This apparent concern can be proven from the various events that include the teaching and learning of Mathematics as a subject of study, books dealing with the theme, varied publications and the recommendations of the country's normative documents, such as National Curriculum Parameters - PCN, PCN + , National Education Guidelines and Bases Law - LDBEN, and the National Curriculum Guidelines for Basic Education. In this scenario, mathematical visualization constitutes a means of developing relevant skills in subjects, not only for the broad and meaningful understanding of mathematical knowledge, but for life in society. In this context, this work aims to understand how teaching is taking place. and learning mathematics, through mathematical visualization related to problem solving, in the country. Thus, the intention to analyze the ENEM selections arose, focusing on the problems with the highest percentage of error and which demonstrate the lack of visualization for resolution. Problem solving is, in this universe, a method to be followed to assist in the resolution process. Still, as we solve the selected problems, we make available material that can be useful to anyone who is interested, especially to the Basic Education teacher. , as a means of helping and encouraging the use of visualization in the classroom.
