A temática medicamentos em uma perspectiva CTS para discutir conceitos químicos

Abstract

In High School, Chemistry is considered unattractive to most students, who do not consider it useful or important, as they cannot relate the contents they learn in the classroom with the phenomena they observe in their daily lives. In the search for contextualized teaching, the CTS perspective can promote an articulated discussion involving issues related to science-technology-society, contributing to a re-signification of scientific concepts. In this context, the theme “Drugs” can be a starting point for the teaching of Chemistry in a CTS perspective. This work proposed the elaboration and application of a sequence of activities for the teaching of Chemistry based on a CTS perspective based on the theme “Drugs”. The research was based on the precepts of the teaching-learning sequences research line that use some design principles to plan, apply and evaluate these sequences in the classroom and the three pedagogical moments. The subjects of the research were the students of the first year of High School of a state school in Uberaba (MG). In general, students reported that they understood the chemistry concepts covered in the didactic sequence, including those previously seen in the discipline of chemistry in a traditional way. The didactic sequence proposed in this work presents a contextualized approach to Chemistry that aims to contribute to a critical citizen formation of students.
