O ensino do movimento retilíneo uniforme e uniformemente variado sob a perspectiva semiótica de Duval

Abstract

This research is characterized as a translational and field study with a qualitative approach, whose main objective is to investigate the contribution of using different representations of Uniform Rectilinear Motion (URM) and Uniformly Varied Rectilinear Motion (UVRM) to the conceptual teaching-learning process and problem-solving for 9th-grade students of Elementary School II. The results of this investigation stem from the implementation of a Didactic Sequence, with a teaching methodology grounded in Raymond Duval's Theory of Semiotic Representation Registers (TSRR), applied to 72 students from two 9th-grade classes of the Colégio Militar da Polícia Militar do Amazonas I (CMPM I), designated as the intervention group. To answer the research question, the learning gain in two tests was compared between the intervention group and the control group, consisting of seventy-eight students from two classes of the same school who received traditional teaching, using Hake's normalized gain. Additionally, the learning evolution within the intervention group was verified throughout the teaching-learning process resulting from the implementation of the TSRR-based methodology. The analysis of the results was conducted using the technique known as content analysis, aiming to examine and interpret the meanings present in the students' responses. The Hake factor demonstrated an average learning gain in the intervention group compared to the control group. Furthermore, the evolution of the intervention group's results between test 1 and test 2 suggests that the TSRR represents a promising methodological path for physics teaching, especially in content that allows for multiple representations. Finally, a Didactic Sequence (DS), developed and reformulated to overcome the learning difficulties identified in both the literature and the learning environment where we implemented its preliminary version, is presented as an educational product.
