Estudo sobre a aprendizagem de porcentagem utilizando redução de figuras em malha quadriculada

Abstract

This study investigates the importance of diverse pedagogical approaches to enhance the quality of mathematics education, aiming to create inclusive and meaningful learning environments. In a post-pandemic context, educators face the challenge of minimizing learning gaps that emerged during remote teaching, necessitating a reassessment of traditional pedagogical practices in favor of more dynamic and contextualized methods. The research focused on students' understanding of percentage calculations, specifically in reducing plane figures by 50% on grid paper. Initial results indicate that over 80% of students mastered basic percentage calculations but encountered difficulties in applying these concepts practically, with only 32% performing the task correctly. Identified limitations underscore the urgent need to develop not only theoretical understanding but also practical skills such as manipulating proportions and geometric scales. This qualitative study, based on bibliographic analysis and classroom data collection, suggests that educational strategies should emphasize the real-world application of mathematical concepts, integrating technological tools where appropriate.
