Modelagem matemática visando à uma aprendizagem significativa na construção e desempenho de um carregador de celular solar

Abstract

This work aims to analyze the contributions that the use of Mathematical Modeling combined with the construction and use of a cell phone charger with solar energy brings to the learning of Mathematics in High School, seeking a Meaningful Learning. From this perspective, Mathematical Modeling was used in the process of building and modeling the performance of the charger, as a methodology to achieve the proposed objectives. The concepts of electricity generation, photovoltaic energy and the relevance of these themes in the current context were presented. Then, the concepts of components and electrical circuits were presented, in addition to the Mathematical Modeling techniques such as linear regression and quadratic adjustment, fundamental for the development of this work. After the construction of the charger, measurements of the electrical current and voltage generated by it were taken, for the plot graphs of the electrical power obtained in relation to time. Then, Mathematical Modeling techniques were applied to obtain the mathematical models that characterize the operation of the charger. Through this work, a pedagogical proposal (pedagogical sequence) was developed to be used by the high school mathematics teacher. The resulting considerations at the end of this work point to the potential of using Mathematical Modeling to satisfy the meaningful learning process. The proposal presented in this work can be used in future works, as well as its application for a better analysis of the significant teaching potential considered here.
