Uma unidade de ensino potencialmente significativa sobre frações aplicada na disciplina de didática da matemática do curso normal

Abstract

This work presents the planning, application and evaluation of a Potentially Significant Teaching Unit (UEPS) on Fractions Applied in the Mathematics Didactics Discipline of the Normal Course, linked to the Postgraduate Program in Science and Mathematics Teaching (PPGECiMa) from the University of Caxias do Sul (UCS). The research was developed at the Irmão Getúlio State Education Institute, located in the city of Vacaria, in a third-year Normal Course class, with 14 students. The teaching unit was organized into eight stages with specific activities for learning Fractions content. The analysis of the results of applying the proposal was carried out using diagnostic assessment and final assessment instruments, in addition to the construction of initial and final conceptual maps. The research was carried out based on David Ausubel's Theory of Meaningful Learning, with the analysis of conceptual maps based on an adaptation of Novak and Cañas' Topological Taxonomy. Active learning strategies were also used in the UEPS stages, such as: Think-pair-share, In-class exercises, Thinking-aloud pair problem solving and the Flipped Classroom. The results showed that the adopted methodology has the potential to promote meaningful and lasting learning. [resumo fornecido pelo autor]
