Polímeros no esporte: Uma sequência didática para o ensino de química

Abstract

This work presents a proposal for a didactic sequence that uses polymers in sports as a contextualizing axis for teaching Chemistry in High School. The research, of an applied nature and qualitative approach, was developed with students of the 3rd year of high school at a public school in Cocal-PI. The theoretical framework was based on concepts about polymers, active methodologies and contextualized teaching. The methodology adopted traditional classes and active methodologies, with the application of diagnostic and post-intervention questionnaires, in addition to carrying out simple experiments with polymers, such as the production of slime from milk. The results demonstr ated significant evolution in the understanding of the concepts addressed, highlighting the effectiveness of using experimentation and contextualization in the teaching-learning process. Data obtained through questionnaires and discussion groups revealed greater interest among students in classes that incorporated active methodologies, especially those that related theory and practice in a concrete way. The discussions showed that the use of themes present in everyday life, such as sports, contributes to making chemical content more accessible and meaningful. It is concluded that the contextualization of polymers in sport represents an effective strategy for teaching Chemistry, as it promotes more engaged, critical and interdisciplinary learning, aligned with the contemporary demands of education
