Abstract

In the context of educational reform aimed at developing students' competencies and qualities, as well as promoting digital transformation in education, the development and use of digital learning materials (DLMs) in chemistry teaching have become increasingly important. Chemistry, particularly the topic "Electrochemical cells and electrolysis" in the Grade 12 Chemistry curriculum, has numerous practical applications; however, students often encounter difficulties in understanding its abstract concepts and underlying processes. DLMs can help visualize knowledge, enhance learner interaction, support self-directed learning, and facilitate students' understanding of electrochemical processes, electron transfer mechanisms, and electrode reactions. This article presents an approach to developing and using a set of AI-supported digital learning materials for teaching the topic "Electrochemical cells and electrolysis" in Grade 12 Chemistry through a blended learning model. The research findings contribute to clarifying the theoretical and practical foundations for integrating DLMs into chemistry teaching. Furthermore, they demonstrate the necessity and feasibility of leveraging digital technologies to innovate teaching methods and enhance students' interest in learning chemistry.
