O estudo de ondas mecânicas através de abordagem investigativa com enfoque na aplicação tecnológica

Abstract

The work presented here was born from the need, as a Physics teacher, to innovate the teaching method in the classroom, seeking to arouse the interest of students through investigative classes with a focus on technology. Therefore, we present a proposal aimed at high school physics teachers, with the perspective of working on the content of sound waves from application in ultrasound. We aim to make students understand the phenomena and physical concepts involved in the formation of the image during this exam. For this, we use investigative situations, problematizations, simulations, experiments, texts and videos during the scheduled classes. In this sense, we seek to work with investigative activities, giving the opportunity for students to act in a reflective and active way in each proposed situation, enabling discussion during classes, in order to expand their knowledge about science. After the didactic intervention, we realized that the educational product generated from this work aroused the students' curiosity during the developed classes and that bringing content that is related to technological equipment can fill the gap caused by expository classes and based on problem solving without many meanings for students.
