Abstract
This article presents the process of developing, implementing, and testing the electronic textbook “Interactive Environmental Lessons: Digital Technologies and Methodological Approaches” within the framework of environmental education. The study combines theoretical analysis of modern interactive educational resources - including gamification, virtual and augmented reality, web platforms, and mobile applications - with practical testing of the developed digital textbook in real educational settings. A total of 20 environmental lessons were conducted with the participation of students from various educational institutions in Kazakhstan. The testing evaluated the textbook’s effectiveness in improving students’ environmental literacy, engagement, and ability to apply sustainable development principles in practice. Quantitative and qualitative data were collected through questionnaires, observation, and feedback analysis. The results demonstrated a significant increase in environmental awareness, active participation, and retention of material. The article also discusses technical and methodological challenges encountered during implementation and offers recommendations for integrating interactive digital textbooks into the educational process to foster sustainable environmental competencies.
