This study bridges theory and practical teaching by exploring the factors, processes, challenges, and transformation strategies of incorporating digital devices into art education by elementary school teachers. A case study method was used, selecting four participants. The results show that external factors, such as administrative support and government policies, and internal factors, such as personal traits and digital literacy, influence the transformation of digital teaching. During the process of integrating digital devices into art education, teachers adopted a student-centered approach, tailored to the context, using group learning models and explaining teaching steps in phases. Challenges in the teaching process included the variability of digital content, insufficient teaching manpower, and the reliance on teachers’ professional knowledge growth, as well as the influence of hidden curriculum culture. Therefore, teachers employed diverse teaching strategies, such as digital conversion of teaching materials, multiple assessments, and adjusted teaching content and methods based on student performance. The study provides valuable experience in designing digital teaching strategies and offers alternative solutions to address equipment shortages, promoting professional development.
