A eletricidade e seus riscos: uma Perspectiva Reflexiva para o Ensino de Física

Abstract

The physics teaching in middle level in Brazilian public schools has become something challenging and worthy of concern. Increasingly, the level of interest and student learning has decreased. With the increasing use of electronic devices such as mobile phones, tablets and computers, the teens realize easily the distance between the attractive content of these technological devices and traditional classes with blackboard and chalk. In order to demonstrate that the physical part of students' daily life, we use the contents of the electricity in a teaching sequence with students of the 1st year of high school. To arouse the interest of students about physics teaching content, we developed a study project on the risks of using electricity in homes, trying to awaken in them the curiosity and investigative sense. The project was developed as part of the specialization course of sciences for research of Science and Mathematics Teaching Center of Minas Gerais University, Faculty of Education of Minas Gerais (CECIMIG / UFMG). The central idea of the project came from the perception of the teacher about the lack of information and knowledge of their students on how to prevent electric shocks and the high rate of fatal accidents involving electricity in Brazil involving children and adolescents. For this, a physical education strategy for a class of 1st year of high school in a public school in the city of Sete Lagoas, Minas Gerais, involving electricity contents and risks of its use in homes of these students was developed. The project was developed in three stages that allowed students to investigate the problem, do records and draw up suggestions for troubleshooting in electrical installations and identify possible potential of electric shock in their homes. During the work the students had the concern to investigate not only their homes but also schools and other environments they attend.
