O uso do aplicativo Phyphox como instrumento para o ensino de física no ensino fundamental

Abstract

This work aims to propose a manual of Physics experiments to be used both in High School and in Elementary School, containing two low-cost scripts based on data acquisition through different sensors available in smartphones through a free application called Phyphox. Based on the assumptions of Vygostsky’s socio-constructivist theory and of David Ausubel's theory of meaningful learning and how it can be applied in a teaching context based on experimental activities carried out in groups, it is expected that the application of the proposed experimental scripts will bring greater meaning and learning of the approached concepts when compared to Purely theoretical classes, only with mathematical definitions and expressions. Teachers are also expected to use their creativity to develop new experimental activities based on the sensors present in a smartphone and the Phyphox application. Each script was planned to be completed in two classes, within a classroom that contains elementary school students, more specifically, eighth and ninth grades, with proposals that fall mainly into the fields of investigation, experimentation and verification of the concepts seen in the classroom. The content of each script presents, in addition to the methodology of the proposal and the class for which it is intended, a brief summary of the physics content addressed in the classroom and the specific sensor that will be used in the experiment to be performed, so that each one of the proposed scripts can be worked independently of the others. The themes chosen are related to the contents of Mechanics and Acoustics. The analysis of the results after the application of the scripts demonstrates a great precision of the data obtained with the smartphone through an easy execution of the experiments by the students, as well as their learning in a more meaningful way with regard to the content taught in a theoretical and equational way in the classroom.
