O uso de videoanálise no ensino de colisões em uma escola pública da cidade de Manaus

Abstract

This monograph highlights the use of video analysis in the teaching of collisions. How can we handle cases where the collision is not perfectly elastic (or inelastic) and describe the phenomenon? The real cases commonly observed are not those with  = 0 or 1. We consider that the collision between two objects in which a ball falls to the ground is frontal and that the masses of the objects are known; the initial and final speeds of the ball will be determined with the Tracker software and with them we could know the restitution coefficient. The objective of this research was to evaluate how the use of computer simulators, through the one-dimensional collision problem (for cases in which the restitution coefficient assumes values 0 <  <1), can be significant (or not) for teaching Physics. The research presented here is of a descriptive qualitative and quantitative approach, which, in the quantitative part, seeks to involve obtaining descriptive data about people, places and interactive processes by the direct contact of the researcher with the studied situation, seeking to understand the phenomena from the perspective of the subjects , that is, of the participants in the situation under study. When framed as a qualitative research, the approaches used for such purposes were the action research that can be labeled in such a way when there is really an action on the part of the people involved in the investigative process, seen from a social action project or from the solving collective problems and being centered on participatory action and the ideology of collective action. Six moments are worked on, in which the first moment refers to the students' previous content. The second moment is about the presentation of the collision content. The third moment will be the presentation of the Tracker. The fourth step is the application of action research to the collision problem. The fifth moment was video analysis. The sixth and final moment was the application of the final questionnaire. Despite the efforts the students did not obtain a significant learning due to lack of previous knowledge to understand the subjects taught in the classroom and with the use of the Tracker.
