ESTUDIO SOBRE LA ENSEÑANZA DEL ÁNGULO PROPUESTO EN EL LIBRO DE TEXTO PARA 4º Y 5º AÑO DE EDUCACIÓN PRIMARIA APROBADO POR EL PNLD/2023

Resumen

This article is part of ongoing master's research and aims to analyze the teaching of angles proposed in the textbook (LD) for the 4th and 5th year of Elementary School. The LD is an essential resource in Mathematics classes, serving both students and teachers, and is present in almost all schools, making it an accessible resource for everyone in the educational field. This justifies the relevance of this research. To develop this study, we used Yves Chevallard's Anthropological Theory of Didactics (TAD) as a theoretical and methodological basis. This framework allowed us to carry out a praxeological analysis and investigate how the teaching of angles is approached in LD, in addition to the prioritized tasks and techniques. The analysis revealed that the majority of proposed tasks seek to explore different techniques. Furthermore, to contribute to the construction of the notion of angle, the authors use contextualization and illustrations of the student's everyday situations.
