Desenvolvimento de uma Unidade de Ensino Potencialmente Significativa para o conteúdo de eletrodinâmica orientada por um protótipo interativo que utiliza a plataforma Arduino para controle de dispositivos e medidas elétricas

Abstract

The present work has the objective of reporting the development of a low cost educational product for the teaching of electrodynamics using the Arduino platform as interface for simulations and data acquisition. For the application of this product a Potentially Significant Teaching Unit (UEPS) was developed based on the Significant Learning Theory of David Ausubel (2000) proposed by MOREIRA (2006).The prototype consists of a set of devices, controlled by the Arduino, connected in such a way that they can simulate the different circuits of a residence. The product is able to demonstrate the electric power and the energy consumed by several electronic devices, besides allowing to understand the operation Of various electronic sensors. The device that has been assembled allows to measure current and voltage through an interactive drawer. Permits will be granted to all material developed so that students, teachers, researchers and other members of society can use, study, modify and freely share all the material produced. The proposal was implemented in two classes of the third year of high school in a public school in a municipality in the interior of Minas Gerais. The results lead us to conclude that the class has become much more attractive and participative, since the students had the pre-disposition to learn, as well as the conceptual and cognitive evolution, the interaction with all theoretical and practical content, relating Increasingly complex problem situations and promoting meaningful learning.
