Produtos naturais e o ensino de Química: uma proposta contextualizada para o ensino médio na cidade de Acauã-PI

Abstract

Contextualized Chemistry teaching enables the construction of learning permeating scientific content and the historical, social and cultural relationship of subjects, from the perspective of critical training. Thus, the research aimed to use natural products as a teaching strategy for contextualized Chemistry teaching. Natural products as a theme in Chemistry teaching allow the study of different chemical concepts, contributing to the relationship between everyday issues. In this sense, 16 students from a 3rd year high school class and 4 Chemistry teachers from the Antônio Rodrigues Filho school, located in the city of Acauã-PI, participated in the research. A bibliographical research and an action research were carried out, with a quantitative-qualitative approach, developed in four stages, the first being the application of a didactic sequence in the classroom; the second and third stages, respectively, the evaluation of the didactic sequence by students and teachers and the fourth stage the return of a final product to the school. It was found that the didactic sequence contributed significantly to the students' learning, being positively evaluated by teachers and students, with emphasis on the contribution to learning, adequate and dynamic planning, in addition to providing a pleasant experience for the students. Thus, the contextualization of Chemistry teaching through natural products represents a methodological alternative capable of assisting in the teaching-learning process and in the training of subjects in its entirety.
