Laboratório experimental de baixo custo para o ensino de física

Abstract

Physics teaching is very focused on a theoretical and mathematical approach, in which students read about the phenomena and solve exercises using formulas and equations. This type of approach alienates the students and makes learning more difficult, as the students cannot see the usefulness of this knowledge in his daily life. According to education theorists, such as Ausubel and Piaget, a more concrete approach, such as the demonstration of physical phenomena through experiments facilitates the student’s learning process. However, the reality in several schools, mainly in the public schools, does not allow this approach, because, even if there is space for the laboratory, teachers are often not prepared to use them, as there is also a lack of time to set up the experiment and prepare the class satisfactorily. This paper aims to equip a laboratory with low-cost experiments and quick assembly so that the teacher can use and supply the need in such situations and help students to have a better understanding of the subjects studied in the classroom. For that, the experiments were assembled and applied in a school. In addition, it is demonstrated, through a questionnaire, the student's interest in carrying out experiments in the laboratory.
