Composição de paródias: um recurso didático para compreensão e conceitos sobre circunferência

Abstract

The present research study reports a qualitative investigation which aims to developing and to evaluating an alternative teaching methodology using the composing of musical parodies for Mathematics teaching attempting to contribute to students learning, especially those of High School. For this, a case study was carried out in a public high school in Campina Grande, Paraíba, with 36 students of the third year. Thus, a didactical approach was developed, adopting as a didactical resource the composing of musical parodies in order to provide a contribution for the learning of the circumference concept. The research study was proposed based on the didactical contract and the theory of didactical situations by Brousseau. The study was divided in two parts. First, the circumference concept was approached by the research teacher to four groups of the third year through a conventional approach: presentation classes. Second, as a way of ending the circumference concept, it was proposed to the students of the four groups to compose, in groups freely chosen by them, a parody by using songs they had been free to select, altering the lyrics so that they could include the subject given in the classroom. Each group composed their own parody, resulting in four parodies. Throughout the study, students were given a set of exercises with questions about circumference so that the mathematical knowledge reached could be evaluated. The data collection was done in six parts, and the research environment was the classroom. The analysis of the data was done by the triangulation technique. As a result, the study has shown, initially, that students prefer a Math class of subject presentation, and the parody composing class leads to a more dynamical, interactive and stimulating class. The study also has shown that students do not have difficulties in adapting to the rupture of the didactical contract when achieving the proposed assignment in returning. The research data pointed out that the composing of parodies results in improving the learning of the circumference concept. Thus, in conclusion, the composing of parodies as a didactical resource can contribute to learning mathematical subjects.
