A aplicação de uma sequência didática utilizando um experimento debaixo custo sobre o Movimento Retilíneo Uniforme

Abstract

When we analyze the teaching of physics, it is possible to notice the range of difficulties faced by teachers and students, from high school and even in higher education, this difficulty comes from a great attachment by educational institutions and teachers, to traditional teaching that is developed mainly through memorization and exercise solving, in the face of this the students see no practical and meaningful meaning to their daily lives, resulting in disinterest and poor performance. Thinking about these difficulties and about contributing to a meaningful teaching of Physics, helping in the correlation of theory with practice, this work aims to present the results of a study through a didactic sequence with a low-cost experiment, making use of the three pedagogical moments approach, in order to verify if the use of low-cost concrete materials can help in the teaching-learning process of Physics, and alleviate these difficulties. From the methodological point of view, the research was qualitative-quantitative, with an explanatory objective, and with experimental and participant procedures. The didactic sequence was divided into three stages according to the proposal of the 3 pedagogical moments. In general, the results indicate that the didactic proposal contributed significantly to the students' learning, being satisfactory for the didactic sequence applied, besides corroborating the educational method adopted. The questionnaires point to an evolution in the understanding of the content since most students answered correctly, besides the positivity in the qualitative observation. As for the methodology used, it was well evaluated and accepted by the students, thus we consider the use of experiments that relate theory to practice to be viable for teaching Physics
