A Problematized Approach to Food Antioxidants: A Didactic Workshop Experience in a Public School in Natal, Brazil”
redox. scholar food. chemistry teaching.
The dificulties founded by high school students in learning redox reactions often relate to distinguishing between the concepts of oxidation and reduction, as well as identifying oxidizing and reducing agents. This study adopts a qualitative approach through participant observation and aims to develop a didactic workshop based on contextualization and problem-based learning, addressing the topic of antioxidants in school meals. The workshop will employ inquiry-based teaching strategies through problem-solving activities. The research will be conducted with a second-year high school class, and the study will explore key Redox concepts—oxidation, reduction, oxidizing agents, and reducing agents—within the context of dietary antioxidants. The objective is to propose alternative didactic strategies to teach redox reactions by connecting them to the food consumed in school meals. Through questionnaires and analysis of a researcher’s logbook, the study will examine students' conceptual understanding, aiming to assess conceptual reinterpretation and engagement with both the subject matter and classroom activities. It is expected that the study will foster interest in nutrition while simultaneously deepening students’ comprehension of redox reactions in everyday life, thereby enhancing their engagement in Chemistry classes.
