Photography in the Textbooks of PNLD 2021: A Descriptive Analysis of the Collection Matter, Energy, and Life

Abstract

Scientific photography plays a crucial role in documenting and communicating data and studied phenomena, as it facilitates the observation and analysis of information that is often presented solely through text. This research investigates the influence of photographs in the teaching of chemistry in high school textbooks approved by the PNLD 2021–2024. The study seeks to answer how photographs contribute to the understanding of chemical concepts, influencing students’ interest and motivation, and impacting the quality of teaching and learning. The methodological approach is qualitative, based on bibliographic analysis. A textbook collection was examined, focusing on the use of photographs to illustrate chemical concepts, demonstrations, and practical applications. The main findings indicate that photographs in chemistry textbooks serve important functions, providing visual representations that complement the text and exemplify chemical phenomena. The analysis of 779 photographic images from the collection "Matéria, Energia e Vida: Uma Abordagem Interdisciplinar" highlights that photographs are essential in bringing students closer to the content. It is inferred that the use of photographs in chemistry education constitutes an effective pedagogical strategy, as it enhances the understanding of abstract concepts through visual representations. This approach contributes to making the content more accessible and engaging, fostering a dynamic, meaningful, and intellectually stimulating teaching-learning process.
