Matemática financeira no contexto da educação matemática crítica: uma proposta para o ensino médio da rede pública de ensino

Abstract

The objective of this work was to analyze the contributions that the teaching of Financial Mathematics, from the perspective of Critical Mathematics Education through the application of investigative activities, could bring to the formation of critical and financially well-educated students in the 3rd year of High School. The research in question had qualitative and interpretative characteristics with quantitative aspects, since it analyzes were based on the interpretations of situations that occurred in the teaching and learning process. From this perspective, a sequence of investigative activities was developed and applied based on the topic of Financial Mathematics, from the perspective of Critical Mathematics Education, involving students from the 3rd year of high school at a state public school in the city of Ponta Grossa - PR. The data used in this work were found through different instruments, including: a questionnaire administered to students, activity reports, as well as observation by the researcher. The results indicated that the students were engaged and enthusiastic about participating in a different methodology, which places them as protagonists in the teaching and learning process, as was the research proposal. This leads us to realize that the concepts of Financial Mathematics, when working with the proposal of Critical Mathematics Education and investigative activities, contribute to students learning autonomously and participatively, through real situations that encourage them to think beyond formulas. and calculations, to have initiative, to debate, to have critical sense and to become responsible for the construction of knowledge. This shows that the research developed was relevant to the teaching and learning process of Financial Mathematics content, since, despite the students having considerable difficulties with basic operations and work concepts, as they were involved, these difficulties were overcome with more ease and lightness.
