Abstract

Background and Objectives: Education through formal schooling is one of the most effective strategies for reducing the CO₂ footprint and addressing global warming. Chemistry textbooks, by integrating theoretical knowledge with real-life applications, can serve as a platform for conveying environmental concepts and climate change awareness. This study aimed to analyze the content of chemistry textbooks in the new educational system and compare them with those of the former system regarding their attention to issues related to global warming and climate change. Methods: A qualitative content analysis with a deductive approach was employed. The research population included all chemistry textbooks from both the new and old educational systems. A framework with four main codes was developed to categorize and code the relevant concepts. Findings: The content of the new system’s textbooks demonstrates considerably greater attention to global warming-related issues, particularly in the categories of solutions and education/awareness. In contrast, the former system’s textbooks show limited focus on these topics. Conclusion: The findings indicate that the new educational system has incorporated more substantial attention to environmental issues and global warming, embedding practical measures and educational content that can enhance students' awareness and attitudes. These content improvements represent a significant step toward strengthening environmental education and fostering well-rounded student development. Nevertheless, there remain opportunities to further enrich fundamental concepts, raise awareness, and promote sustainable attitudes.
