A química forense como ferramenta de incentivo para o ensino-aprendizagem de Química: práticas experimentais didáticas no ensino médio

Abstract

For many high school students, the term Chemistry refers to something difficult to understand, memorize and have little meaning. This research sought to provide an incentive to learn Chemistry in a didactic way using Forensic Chemistry as a tool. For this, a field study was carried out at the Senador Chagas Rodrigues State School in the city of Parnaíba - PI with students of the 3rd year of high school. The didactic proposal applied, had a sequence of theoretical class and practical class seeking to demonstrate the applicability of Chemistry and consequently its importance, which through a methodological approach becomes more attractive for students. For that, forensic techniques were used, and from this, to enable students to see Chemistry not only as a matter of formulas and theories, but something present in their daily lives. In order to validate the didactic proposal, a questionnaire was applied to the students before and after its application, whose results pointed to a change of opinion after the application of this methodology. In this way, it was observed that the research participants concluded the objectives outlined in a positive way, awakening in several the interest in the discipline again through a contextualization in teaching
