Sequência didática para a aprendizagem significativa da acústica física e da acústica musical, relativas aos tubos sonoros, utilizando organizadores prévios e atividades experimentais com o tubo de Kundt

Abstract

In this research, we seek to innovate the teaching of acoustic sound tubes, usually worked in schools in traditional way, through the construction and use of an experimental apparatus of Kundt's tube version, as well as the development of an educational product where, we present a didactic sequence research and motivating, to teach physical acoustic and musical acoustics in sound tubes, through previous and experimental activities organizers, with an active students participation in the construction of their own knowledge. For that, it was built up a potentially significant material, that started from the assumption that the student had a prior knowledge of the subject, which from this knowledge, we can work all theory involved, joining the previous knowledge with the new one. This construction was made from the meaningful learning theory of David Ausubel, relating subsumption, elements of the cognitive framework, for meaningful learning of a new content.
