Smart Object como Ferramenta Pedagógica para Abordar Acidentes Químicos no Ensino Médio

Resumo

Chemical accidents are present outside industrial and technological environments, making it important for students to be aware of the chemical risks that surround them. Thus, this work proposes the use of chemical accidents as a way of contextualizing chemistry teaching and promoting meaningful learning based on students’ prior knowledge about situations that may occur in their daily lives. In addition, the use of technology as a supporter of science teaching is emphasized, enabling students to develop a broader view of the subject while fostering deeper understanding without disregarding their everyday reality. Therefore, the objective of this work was to propose and apply smart objects (SO) designed to address chemical accidents in Chemistry classes, to promote students’ awareness of this problem while working with basic disciplinary content. A practical guide for the development of SO using QR codes was also prepared for teachers. Three SO were developed, while two were applied: radioactivity SO was applied to students at Colégio Pedro II, and the combustion SO to undergraduate students at UFRJ. The results indicated that both groups were motivated to use the SO, suggesting that these resources can support active learning and be adopted by teachers in their practice.
