A robótica educacional como ferramenta de ensino de Física no ensino médio: aplicação dos experimentos semáforo e sensor de umidade do solo

Abstract

This study investigates the use of educational robotics as a tool to support Physics teaching in high school, aiming to understand how practical activities can contribute to students' meaningful learning. The research presents the construction and application of two experiments: an electronic traffic light, used to address concepts such as electricity, voltage, current, and circuits, and a humidity sensor, which enables the exploration of physical quantities, sensors, and variations in electrical resistance. The methodology involved practical classes, assembly of the devices, and the application of questionnaires to students, allowing the analysis of their perceptions regarding the learning process. The results indicate that robotics enhances students’ interest, develops skills such as teamwork, critical thinking, and problem-solving, and makes physical concepts more concrete and understandable. It is concluded that integrating robotics into Physics teaching significantly contributes to students’ scientific and technological development, making the learning process more interactive, contextualized, and engaging
