Física experimental com arduino: uma abordagem para o estudo de eletricidade no ensino médio

Abstract

This work aimed to develop low-cost experiments for teaching Electricity using Arduino in High School. This strategy was proposed to diversify the traditionalist approaches presented in Physics teaching. The activities developed were taken to the classroom, expanding the teaching of concepts of Uniform Electric Field and Electric Potential, especially the topic of equipotential surfaces between parallel plates. For this purpose, the Arduino platform was used, a versatile electronic prototyping resource that can be used in the development of various projects and activities. In this aspect, technology emerges as a tool that aims to assist the teaching process, providing innovative methodologies based on experimentation.The research is qualitative and quantitative in nature, and data collection was performed using assessment instruments (questionnaires) before and after the experiments. To assess students' perceptions of Arduino, a questionnaire based on the Technology Acceptance Model (TAM) was applied. The research was conducted in two 3rd-year high school classes at a state school in Oeiras-PI. The results showed that experimentation associated with the use of Arduino contributed to partially significant learning, considering that there were correct answers for some questions and divergent results for others, suggesting adjustments to the methodology. Despite the challenges, the proposal proved to be a viable alternative for making teaching Physics more interesting and motivating. With this approach, it sought to contribute to overcoming challenges related to student engagement. Thus, the pedagogical intentionality was explored with a low-cost technological resource aiming at significant learning.
