O uso do Scratch para o ensino e aprendizagem de equações algébricas do primeiro grau

Abstract

This paper aims to evaluate the contributions of Scratch, through a constructionist methodology, in the meaningful learning of the concept of algebraic equations of the first degree. The experimental part was conducted with students regularly enrolled in the 8th grade of a state school in Lages / SC. The proposed activities were developed in mathematics classes, using 10 meetings in a total of 16 hours. For data collection, a qualitative investigation was adopted, conducting interviews before and after the development of the activities, through semi-structured questionnaires about first degree Algebraic Equations and Computational Thinking. During the interventions, Scratch software was presented as a tool to help solve algebraic problems and encouraged students to build their own projects. It was observed that in this scenario Scratch helps to supply the students difficulties regarding the content of Algebraic Equations. The results demonstrate a significant improvement in the interpretation of the algebraic variable and a greater interest in the contents of mathematics.
