Uma proposta de ensino sobre magnetismo a partir de atividades com materiais de baixo custo – construção de eletroímã

Abstract

The objective of this work was to elaborate a didactic sequence based on experimental activity through an investigative approach with classes of regular education and the teaching of youth and adults (EJA) with low-cost materials on initial issues of magnetism and electromagnetism. We were able to verify that the students had their own explanations for the phenomenon even though the national parameters were satisfied they lacked a more technical scientific view. From the activities developed and the diferent work group during the implementation of the proposal, we can see that the activities ended up showing a new “how to” regarding the teaching and learning of physics. Since the traditional methodology would not have achieved the desired result - a real challenge for the teaching of Physics in high school. In research activities students are involved in the identification of physical phenomena, non-development of the phenomena, in the modification and improvement of their preconceptions related to the subject. Also, an intense collaboration with colleagues and exercise of their reasoning skills. The great challenge is to structure teaching materials would enable students of different backgrounds to reach the same expected scientific knowledge, in such a way as to apply it in different contexts that involve the same concept worked on.
