Desenvolvimento de uma bomba simulada com arduino para o ensino da associação de resistores

Abstract

Acquisition and retention of knowledge are fundamental elements in the learning process, especially in the context of teaching complex subjects such as Physics. In this sense, it becomes imperative that teaching methods adopted in schools stimulate active construction of knowledge by the student, promoting a meaningful connection between new concepts and students' prior knowledge. Given this, the present study aimed to develop an educational product aimed at promoting meaningful learning about resistor association, involving students in theoretical classes and experimental laboratory activities, culminating in disarming a simulated bomb developed with Arduino. The research was conducted at a State School located in Mato Grosso do Sul, with a 3rd year high school class. Initially, a diagnostic evaluation process was conducted through a questionnaire of knowledge about resistor association, with the aim of adapting theoretical classes to the students' level of knowledge. Subsequently, students were subjected to experimental classes related to the challenge of disarming a simulated bomb, in which they were divided into groups, responsible for calculating voltage or electric current in specific resistors. The challenge involved disarming a simulated bomb, with two distinct stages. After completing the activities, students were subjected to a new assessment to compare the results with the diagnostic assessment, allowing quantification of student learning and identification of growth areas. The results showed a significant improvement in students' performance, indicating a deeper understanding of resistor association concepts after implementing the educational product. The practical and challenging approach adopted in the study contributed to student engagement and facilitated learning, highlighting the effectiveness of this teaching methodology. Therefore, it is concluded that the educational product developed was successful in promoting meaningful learning of students about resistor association.
