ELABORAÇÃO DE UM CONJUNTO DE MATERIAIS DE APOIO E APARATOS EXPERIMENTAIS PARA O ESTUDO DE ONDAS MECÂNICAS POR MEIO DE CORDAS

Abstract

This study presents the development of the Product – In the strings of musical instruments – and analysis of its application. Basically, the Product is a set to study mechanical waves through experiments and the use of musical instruments, both created with alternative material which is easily available. The product aids the teacher and comprises: text with approach to the physical concepts worked in the classroom; texts supporting teacher’s work and texts supporting students’ work, unit plans and lesson plans; manuals guiding the apparatuses assembly and their use in the classroom. This proposal contains 08 (eight) sessions, distributed into 12 (twelve) lessons, which seek, from a teaching sequence, to approach wave basic concepts and develop those concepts at the high school level aiming at providing advances to the teachinglearning process regarding the students involved. In such elaboration, the activities were based on Ausubel’s learning theorie. Finally, from the Product use and analysis, it was seen that the sequence of lessons given made it possible to enhance the study of mechanical waves through strings, and the activities with musical instruments and experiments developed in the classroom provided the students better interaction with the content worked, since these practices motivated them to inquire and observe in their own context the physics content being studied. Therefore, the product application, through a differentiated practice, resulted in advances to the learning-teaching process in a meaningful manner.
