O arduino e o visual basic como recursos didáticos na prática experimental para o ensino de eletrostática e primeira lei de OHM

Abstract

The technology and experimental practice are inseparable from physics education. However, from Vygotsky's ideas, one must understand that only the experimental practices and the technology alone are not the only requirement for the student to learn certain contents, it is required the constant presence of the teacher as a mediator. In this research, we start from this assumption to investigate how the experimentation allied to the technology can be important in the learning and the motivation of the students. In this master's thesis, we present the classroom implementation of an educational product based on Arduino microcontroller and Visual Basic programming language, in the experimental practice of physical discipline, more specifically in electrostatic and first Ohm’s law. Applications occurred in two groups of the third year of Technical Medium Teaching Professional in Building of the Instituto Federal de Educação, Ciência e Tecnologia do Sertão Pernambucano — campus Salgueiro. We used a qualitative (interpretative) research methodology for the development and testing of interventions and results. We conducted a careful analysis of the students' behavior during the realization of the proposed activity, as comparison, we also analyzed the reports produced after the practices to establish a parallel between the discussions and the responses received at the time of activity and after it. From the data obtained during the applications and through the reports, we can see that the presence of the teacher throughout the experiment is necessary, interfering in a precise way and observing student performance and making questions that lead students to rethink the contents studied in a practical way. In addition to this, we also noticed the students showed great interest in the experiments carried out, so that they appear to be more motivated to learn rom practices such as those carried out in this work.
