Uma proposta para o ensino do movimento retilíneo uniforme utilizando fotoanálise e videoanálise

Abstract

Information and communication technologies (ICT) can enhance the learning of physical concepts taught in high school. This work studies uniform rectilinear motion (URM) using photoanalysis and videoanalysis. The study is systematized with a didactic sequence divided into three moments, totaling six classes. Due to the COVID-19 pandemic, the didactic sequence was applied in a hybrid format to maintain the previously established structure, but still allowing part of the students to experience the proposed educational product. The didactic sequence allows: the historical approach of the cinematograph, the analysis of movement with sequential images, the experimental practice, using two low-cost experiments, and the use of applications: Infinite Shot, Vernier Graphical GW, and Tracker software. With these tools, it is possible to photoanalyze and videoanalyze the vertical movement of a washer along a threaded rod and a sphere that moves inside an inclined hose containing oil. The proposed activities provide a more interesting learning in the study of kinematics from experimentation. To a first approximation, both the washer and the ball move in a straight line and at constant speed. The characteristics of the movement of these bodies are investigated by the students with the use of smartphones associated with the techniques of photoanalysis and videoanalysis. Based on spiral teaching, proposed by theorist Jerome Bruner, the initial concepts of kinematics and specifically of URM are visited and revisited, allowing the gradual construction of knowledge, moving from the most elementary aspects of this movement to the most complex.
