Uso de experimentos no ensino das leis de Newton

Abstract

Physics teaching has often not attracted or motivated students, with the teaching methodology being one of the factors that contribute to learning difficulties. The use of experiments can be explored as a strategy to awaken students' interest in the subject. This work presents the construction of a didactic sequence (SD) with the theme of Newton's Laws, developed through experiments. The sequence was planned for eight regular 50-minute classes: the first class consists of the application of an initial questionnaire to understand the students' perception of the topic; the following six classes are intended for carrying out and discussing three experiments, one for each Newton's law; and the last class is theoretical in nature, including the reapplication of the questionnaire in order to evaluate learning. Although the sequence has not yet been tested, it is expected, based on studies and observations of pedagogical practices, that it will contribute to improving the teaching and learning of Newton's Laws.
