Abstract
Esta dissertação apresenta uma experiência de abordagem do conceito de congruência de figuras planas, no Ensino Fundamental, por meio de estudo das transformações isométricas. O estudo foi realizado com uma turma de alunos do nono ano do Ensino Fundamental de uma escola pública municipal de Parobé, no Rio Grande do Sul. Sob a inspiração do modelo de cooperação investigativa de Ole Skovsmose, foram desenvolvidas atividades de natureza exploratória e investigativa com questões abertas ao diálogo entre os participantes da pesquisa e uso de materiais manipulativos e de um software de geometria dinâmica. As soluções propostas pelos alunos e as discussões realizadas durante o desenvolvimento das atividades foram registradas por meio das produções escritas dos alunos, de gravações em áudio e vídeo e de arquivos elaborados no ambiente do software GeoGebra. As análises desses registros permitiram concluir que os alunos compreenderam o conceito de congruência de figuras planas por meio da exploração e da discussão sobre as transformações isométricas.
This work presents an experience of an approach of the concept of plane figures, in elementary school, through the study of isometric transformations. This study was conducted with a ninth grade group of students of a public elementary school in the city of Parobé, Rio Grande do Sul. Under the inspiration of the investigative cooperation model of Ole Skovsmose, exploratory and investigative nature activities were developed and open questions were proposed in order to establish a dialogue between the participants in the research. The use of manipulative materials and a dynamic geometry software has also been applied. The solutions proposed by the students and the discussion conducted during the activities development were recorded through written papers, audio and video recordings and files created with GeoGebra software environment. Through the analysis of these records, the conclusion was that the students understood the concept of congruence of plane figures through the exploration and the discussion around the isometric transformations.
