Um infográfico como objeto virtual de aprendizagem de fenômenos eletromagnéticos para o ensino médio

Abstract

The present work entitled An infographic as a virtual learning object of electromagnetic phenomena for High School, aimed at the elaboration of didactic material on the subject, which was implemented in classes of 3rd year A and B of high school of the Escola Estadual Marechal Eurico Gaspar Dutra in the city of Barra do Garças – MT. The technological world as we know it, from the simplest to the most sophisticated devices, is forged by the existence of electromagnetic fields: electricity generation, residential and industrial electrical appliances, medical devices, particle accelerators, terrestrial location, electric motors, magnetic cards, etc. However, textbooks do not give an exact dimension of this importance, because the material is often very sectioned, making it difficult to see the whole thing that leads, in the end, to an understanding of the phenomena of electromagnetism. This work was constituted by the conception, elaboration and implementation in the classroom of an instructional didactic material - our educational product - that approaches electromagnetism in an integrated way, starting with a historical survey since the discovery of magnetite and the main scientists involved in the main discoveries about the properties of the magnetic field, its relationship to electric fields and the sophisticated Faraday's Law of Induction, as well as the main applications of electromagnetism in our everyday life and the possibilities opened up by superconducting electromagnets. The educational product, elaborated on the CANVA FOR EDUCATION platform, consists of a sequence of 15 (fifteen) classes, taught remotely, with an emphasis on the theoretical approach, complemented with video experiments, computer simulations and demonstrative experiments. Content fixation activities are highlighted in classes and were designed to engage the student, allowing active, relaxed and interactive participation, through playful activities such as challenges, board games and online games (Kahoot!). As a result of our work, we realized that the set of pedagogical tools consolidated in our educational product - mediated by virtual learning objects - contributed to the deepening of the contents, aroused the curiosity and interest of students in the theme and also promoted scientific dissemination.
