MEANINGFUL LEARNING USING ARDUINO IN A PHYSICS DEGREE COURSE: TRIGONOMETRY, WAVES AND MUSIC

Abstract

Learning Physics is often challenging for students, and this difficulty may be associated with the negative comments that students hear about the subject, coming from colleagues or even family members who have already taken it. The general objective of the research is to enhance the learning of mechanical waves in the Physics Degree course at UNEB, through the use of a device based on Arduino, which integrates trigonometry concepts for the analysis of musical sounds, promoting a practical and interactive approach to the content; and, as specific objectives, the following are considered: a) Build hardware with Arduino to promote the teaching of Physics content, mechanical waves, with the use of trigonometry to analyze musical sounds; b) Measure, through questionnaires, how much the use of the proposed technological tool contributes to increasing students' interest in the subject; and, c) Use trigonometric functions to mathematically model the generated wave patterns, such as sines and cosines, and explain how these functions describe physical phenomena. To consolidate these objectives, a hybrid methodology was adopted involving a literature review, of a historical, descriptive, documentary and theoretical nature, based on a case study in a research universe composed of undergraduate physics students from UNEB, Salvador, with the use of the wave laboratory. Finally, the results obtained are the construction of the product in Arduino, the adoption of a set of strategies for teaching based on the detection of subsumers; the implementation of these strategies, thus assisting and collaborative networks for the teaching of physics.
