O uso de atividades experimentais com materiais alternativos no ensino de Física: um estudo de caso com alunos do município de Aracati

Abstract

It is well known the fact that Physics Education has been undergoing profound and significant changes, thus leading cultural transformations responsible for the emergence of new forms of learning and knowledge production. The use of experimental activities is one of the important tools for the concepts of physics in high school. The methodology used in this study was based on constructivism, a theory advocated by Vygotsky and Piaget, in order to describe the process, the characteristics and the relationships between the concepts of physics and the use of low cost materials. For this, we conducted a case study with a group of students of 2nd year of high school, from a state school in the city of Aracati, Ceará. This alternative proposal for low-cost experiment can be discussed physics involved in thermal expansion, which allows the realization of activities covering considerable physics content in the construction of alternative devices. It also offers students a more meaningful learning, demonstrating the practical application of theoretical concepts.
