Uma abordagem de ensino de Geometria Plana para os anos finais do Ensino Fundamental, usando Scratch

Abstract

Considering the increasing presence of smartphones, tablets, and computers in students' lives, the integration of Information and Communication Technologies (ICT) into the school environment is necessary. This work proposes the use of ICT for teaching topics of Plane Geometry, using the Scratch programming language, which is visual, accessible, and easy to understand. Sequences of activities have been developed for the final years of Elementary School, aligned with the National Common Curricular Base (BNCC), with the aim of helping in the comprehension of the content covered and acquisition of the skills outlined for each grade, while also providing teachers with a new approach to teach geometric constructions. The topics covered include angles, lines, polygons, circles, and congruence and similarity of triangles. By using Scratch, students not only explore concepts of Plane Geometry but also develop logical reasoning and computational thinking inherent to programming languages, in an intuitive and simplified manner through programming blocks. It is expected that the approach proposed in this work will effectively contribute to the teaching-learning process, stimulating creativity, promoting interaction, and consolidating the geometric concepts discussed in classroom.
