Uma sequência didática aplicada em aulas remotas envolvendo o tema lixo para o ensino de cinética química

Abstract

This work proposes a didactic sequence, based on the principles of interdisciplinarity and contextualization, to work with the contents of chemical kinetics in high school, using a CTSA approach and the methodology of the three pedagogical moments. The central theme chosen to be worked on in the didactic sequence was garbage, relating it to Paraiba and the daily lives of students to work on Chemistry content. In this way, we tried to work with the contents in order to approach the present context and facilitate the students' learning, with the final objective of overcoming the students' difficulties and thus achieving a gain in the learning of the worked concepts. The didactic sequence was applied in a public school in the city of João Pessoa, in second-year high school classes, remotely during the pandemic period. Data collection was done through questionnaires, in a qualitative research perspective, applied at the beginning and at the end of the application of the didactic sequence. The results indicate that there was an improvement in the students' ability to relate school content to life in society and the environment.
