Proposta de atividades de ensino por investigação em laboratório de indução eletromagnética

Abstract

The objective of this dissertation is to present educators at schools in the public and private sectors alternatives to produce low-cost electromagnetic induction laboratory equipment with comparable quality to the equipment available in the market, as well as presenting a methodology to take advantage of this material. The teacher is challenged to change from the mechanized traditional method to a format where the student is led to interact with the equipment of the laboratory, to formulate hypotheses about the observed phenomena, to discuss these hypotheses with colleagues and to present results. We present a planning with activities of inquirybased science education, transferring the focus of the learning to the student and enabling their active participation in the process of learning. Teachers and students dialogue and build knowledge from this interaction. The product of this dissertation includes a step-by-step construction of a Tesla Mini-coil, a coil with four thousand wire loops connected to LEDs, a Foucault tube and a flat coil, and propose experiments to use such equipment. We used the POE methodology (predict, observe, explain) in the activity with the Tesla Mini-coil and activities focused on investigation for the other experiments. When applying the product in the schools where the author works, it was possible to perceive that the results were positive, with an increase in student interest, improvement in the relation with the teacher and ease of formalizing the concepts in the theoretical classes.
