Microcontrolador Arduino no ensino de física : proposta e aplicação de uma situação de aprendizagem sobre o tema luz e cor

Abstract

This paper aims to propose the inclusion of the Arduino microcontroller in Physics classes in a public high school. To this intent, a learning situation on the theme Light and Color was suggested, based on meaningful learning and on the use of an interactive and easy to handle experiment. The daily life of students is packed with technologies that hold plenty of Physics’ concepts and applications. The intention to introduce the Arduino microcontroller in Physics classes was to arouse the curiosity and awaken in them the investigative character necessary to the study of Physics while they deal with technological elements that are part of their contemporary culture. The developed activity enables the investigation and allows students to participate more actively in their learning process. During the activity, groups of students tested some possibilities of light mixtures and the relationship between the incident light with the color of the light reflected by the objects. To record and learning verification purposes, a pretest, a posttest, a summative evaluation, teacher’s records and, lastly, a self-assessment were performed. It is possible to conclude that the activity was successful and has awakened the curiosity of the students, enabled conceptual growth and showed evidence of significant learning.
