Aprendizagem ativa em aulas de física: o uso do Arduino em experimentos de termodinâmica

Abstract

Physics is usually reason for dismay for high school students. It is a consensus among teachers that learners present a great deal of disinterest and lack of engagement in relation to the discipline. Thus, in this work we develop and test an educational product that is composed of teaching activities in which didactic experiments are used as tools to answer questions. In the development of our educational product we also use the Arduino to create an electronic interface that allows the connection of temperature and pressure sensors to the computer, thus allowing visualization, manipulation and storage of measurement data. These resources have been associated to create situations in which students have the opportunity to take action, to represent them, to analyze them, to discuss them, and to reflect on what is happening, so that they may feel more knowledge and content of the discipline. Activities related to thermodynamics related to the concepts of heat, temperature and the 1st Law of Thermodynamics were dealt with in the activities. The results showed that the activities had positive effects on students' engagement and learning, and clear evidence of appropriation of scientific language was observed.
