A Química dos medicamentos: Uma proposta contextualizada para o ensino de Química Orgânica

Abstract

The present work presents a proposal for contextualized teaching in chemistry classes. The objective was to develop a teaching proposal using the theme “Chemistry of medicines”, showing the importance of chemistry in a contextualized way. The research was carried out with 3rd year high school students at Escola Centro Estadual de Tempo Integral Paulistana – CETI, in Paulistana-PI, using three pedagogical moments: initial problematization, organization and application of knowledge. Initially, an initial questionnaire was administered to identify students' prior knowledge on the topic "Medicines" and Organic Chemistry issues. Then, in the knowledge organization stage, classes were given on the chemistry of medicines and a review of organic chemistry. In the knowledge application stage, the Fair "The Chemistry behind Medicines" was held, where students presented their research and projects. Finally, a final questionnaire was administered to analyze and understand the content covered. The comparison between the initial and final questionnaires demonstrated a significant increase in students' knowledge about molecular formulas, classification of carbons and identification of functional groups, in addition to a greater awareness of the rational use of medicines and the dangers of self-medication. These results highlight the positive impact of the didactic sequence, providing students with meaningful and dynamic learning.
