Inserção de conceitos de dinâmica rotacional no ensino médio através do laboratório não estruturado mediado por videoanálise

Abstract

This dissertation investigates the feasibility of transposition didactics of the content of rotational dynamics for high school, using the concepts of the lab not structured mediated by videoanalysis. Among the concepts of dynamic rotational, focused on inertia, kinetic energy and rotational angular momentum. For videoanalysis, we used the software Tracker, to encourage the interaction between the experiments proposed, with the resources of image and video, as well as be familiar to students who participated in the activities. This research was based on the principles of the transposition didactics of José de Pinho Alves Filho, who initially were worked by Chevallard, and skills and abilities identified by the National Curriculum Parameters, as well as in his notes for a restructuring of the teaching of Physics. The research methodology was proposed in order to investigate the feasibility of the process of transposition didactics according the rules proposed by the theoretical framework, through the use of Tracker, in the context of the lab not structured. For this reason, three experimental activities were conducted with students of the second series of high school in a college of the private network of Curitiba. From the analysis of the material produced by students and records of the teacher, it was evidence of learning the theme proposed by being unheard of in high school. In this study, it was found that the viability of the transposition didactics of the content of rotational dynamics for middle school.
