Narrativas visuais no ensino de ciências: o mangá “campeão da química” como recurso didático na abordagem da eletroquímica

Abstract

The teaching of electrochemistry presents recurring challenges in high school, mainly due to the abstract nature of its concepts and the limited time available for content development. In this context, this study aimed to analyze the use of an educational manga as a didactic resource in the teaching of redox reactions, comparing a traditional lecture-based class with a class mediated by the manga Campeão da Química. The research was conducted with 20 high school students through questionnaires applied after each pedagogical intervention, including both quantitative and qualitative data. The results indicated increased levels of student motivation, improved conceptual understanding, and better performance in redox-related questions after the use of the manga, especially regarding the visualization of submicroscopic processes. Despite the limitations imposed by the reduced chemistry workload in the New High School curriculum, the manga proved to be an effective complementary resource, promoting meaningful learning. It is concluded that the use of visual narratives represents a promising pedagogical strategy to make electrochemistry teaching more accessible and engaging.
