SUMMARY:

The difficulties reported by high school students in learning redox reactions point to the differentiation between the concepts of oxidation and reduction, as well as defining the oxidizing and reducing agents of the reactions. This qualitative study consisted of a participatory action research and aimed to conduct a didactic workshop based on contextualization and an investigative teaching sequence (SEI), addressing the theme of antioxidants in school meals. Inquiry-based teaching through problem-solving was utilized in the development of the workshop. The research was conducted with a second-year high school class. The study addressed concepts involved in Redox reactions, such as oxidation, reduction, oxidizing agent, and reducing agent, within the context of antioxidants present in school meals. This work aimed to propose differentiated didactic strategies to approach the content of redox reactions within the theme of food in school meals through a didactic workshop. Through questionnaires and the analysis of logbooks, the meanings of the concepts provided by the students were analyzed; for this purpose, the study sought to verify the conceptual re-signification and whether the application of the workshop favored a better understanding of the content covered. The food theme allowed the contextualization of redox phenomena, making it possible to identify the main agents involved in these processes and enhancing the students' understanding of such processes. The use of the SEI approach allowed students to assume the role of protagonists in the learning process, promoting their investigative side, as well as the formulation of hypotheses and evidence, which resulted in a re-signification of the concepts related to the redox content. Teaching Chemistry content, such as redox reactions, proved to be effective through contextualization. The investigative, experimental, and ludic character presented in the proposal also contributed to a better comprehension of the content.
