Sequência didática investigativa baseada nos três momentos pedagógicos de Delizoicov para a determinação experimental da velocidade do som no ar

Abstract

Research in physics teaching has strongly pointed to the importance of using the experiment in an investigative and problematizing perspective, as a tool in the formation of scientifically literate citizens. Such activities, among others, can assume different roles in teaching situations, enabling, in addition to meaningful learning, student protagonism, decision-making, reflective analysis and the construction of conclusions. In line with this emancipatory perspective, we developed a didactic sequence, based on the dialogue between the three pedagogical moments and tailor-made teaching, focused on theoretical and experimental teaching regarding the speed of sound and its measurement. The application of this educational product proved to be quite satisfactory, where we could perceive motivation, protagonism, making it evident the desire of the students that the teaching of physics could be this way, which shows us that the lived experience built in them a new look in relation to the physics. In addition, the experimental results and the conceptual maps produced by them show that learning took place.
