O uso de experimentos de baixo custo na primeira série do ensino médio em particular nos conceitos básicos das três leis de Newton

Abstract

The present paper aims to investigate the learning of students of the first (1st) grade of secondary school, in classes with use of low cost experiments in the teaching of physics, latter being directed the basic concepts of Newton's Laws. The formation of high school students (HS) has come to be seen in a different way in the last years, because the goal of many schools and teachers is to make students come to have greater interaction, motivation and better results. Thus, in this work, it uses of these strategies for adding low-cost experiments at methodologies of teaching of Physics. Two methodologies were applied in this work. The methodology traditionalist, as being the use of whiteboard and paint brush with verb exposure of the content, without any participation of the student during class; and methodology Constructivist, where the student participates actively in the apprenticeship itself, by means of the experimentation type, through dialogue and practical demonstrations. The analyzes were made with the preparation of a questionnaire that it was applied to students of two classes of first-year classes. So after evaluation, compare the results were analyzed by percentages of correct answers utilizing graphics, where it was sought to confirm the use of low-cost experiments facilitates the understanding of basic concepts of physics, in the case of this work, Newton's Laws.
