O Ensino de porcentagem com ênfase em percentuais sucessivos e a contribuição da educação financeira nas turmas do 9ª do ensino fundamental

Abstract

This study aims to investigate the teaching of percentages with an emphasis on successive percentages and how the relationship between this topic and Financial Education is developed in Mathematics classes for 9th-grade students in the municipal school system of Pesqueira-PE. To carry out the investigation, this research relied on the collaboration of five teachers, one from each school, who teach 9th-grade classes in the municipal education network. We used interviews as a data collection tool, conducted via the WhatsApp messaging app. Additionally, we analyzed the textbooks used by the teachers in their classes. From the responses obtained, it was observed that, although Financial Education is included in the BNCC, there are still challenges regarding its effective implementation in the classroom, especially concerning the use of active methodologies and digital technologies. In the analysis of the textbooks, I observedVolume 11 presents a more formal approach, being more suitable as support material for the teacher, given its high level of complexity for 9th-grade students. Therefore, it can be concluded that, although there is an effort by teachers to address Financial Education and the topic of successive percentages, there are still significant challenges, mainly related to ongoing training, technological infrastructure, didactic mediation, and stimulating student interest.
