OXIRREDUÇÃO EM FOCO: UMA ABORDAGEM SOB A ÓPTICA DA CIÊNCIA, TECNOLOGIA E VIDA

Abstract

This dissertation presents the development of a supplementary textbook entitled “Redox in Focus: An Approach through the Lens of Science, Technology, and Life,” created to facilitate the teaching and learning of the redox topic in basic education by integrating scientific, technological, and biological concepts. The material seeks to overcome the limitations of traditional teaching, which often focuses only on calculating oxidation numbers, by promoting a meaningful and contextualized understanding of the subject for elementary and high school students and teachers. The purpose is to develop a supplementary textbook (LPD) that contextualizes the theoretical concepts of redox, stimulates critical thinking, and facilitates the comprehension of redox reactions and their applications. The steps taken include a theoretical review of the topic, highlighting the social relevance of redox reactions, and applying didactic transposition tools to adapt the content for basic education. Redox reactions are fundamental for understanding natural, technological, and biological processes, such as cellular respiration, corrosion, combustion, and the operation of electrochemical devices. The LPD presents the concept of redox in relation to the transfer of electrons and energy, emphasizing its daily relevance and importance to science and technology. The text maintains a focus on science, technology, and their applications in everyday life. The approach broadens the traditional view, aiming to connect scientific knowledge to students’ daily lives, stimulating critical thinking and intellectual autonomy. The methodology is based on bibliographic research, meaningful learning, and external didactic transposition (EDT), adapting complex scientific knowledge into accessible and contextualized content for basic education. The supplementary textbook (LPD) is designed as a complementary resource to traditional teaching materials, promoting a more dynamic and critical approach to teaching redox. The developed LPD offers an integrated and expanded view of the redox topic, highlighting the importance of different explanatory models and their applications in science, technology, and life. By connecting theory and practice, the material contributes to more meaningful learning, overcoming the limitation of teaching focused solely on oxidation numbers. The next step suggested is internal didactic transposition (IDT), which aims at the practical application of the content in the classroom, consolidating learning. This work represents progress in chemistry education, providing an updated resource that can be used by teachers and students to deepen their knowledge of redox and its multiple facets, promoting the formation of more critical citizens who are aware of the importance of chemistry in their daily lives.
