Transposição didática para o ensino e aprendizagem de eletricidade por meio de experimentações com sucatas de placas eletrônicas na 9ª. série do ensino fundamental

Abstract

The paper entitled Didactic transposition for the teaching and learning of electricity by experimenting with scrap of electronic boards in the 9th. The elementary school series deals with teaching and learning in a public school in the city of Manaus, with the use of electronic board scraps on electrical or electronic technology, from a technological device called resistor, for the 9th grade of elementary school. This research was carried out using an experimental method in the teaching-learning area. This device is easily accepted by the students, considering their interest and curiosity on subjects such as electric power, electric current, light bulbs and other industrial appliances that work with electric power. This was also only possible thanks to the mathematical facilities seen by this same class in the previous series, such as first degree equations, systems of equations, potentiation, rooting, and decimal metric system. This set of themes allowed this series to perfectly absorb the subject in question, since it was the curiosity of this class that encouraged this research.
