In the era of "Internet Plus" and artificial intelligence, cultivating design arts talents with comprehensive literacy and innovative capabilities has become a key topic in arts education research. This paper explores the implications of STEAM education for talent cultivation in design arts from a theoretical and practical perspective. By analyzing the connotations and core ideas of STEAM education and integrating them with the disciplinary characteristics of design arts, the study identifies interdisciplinary pathways for education provided by the STEAM framework. In terms of cultivation goals, the study emphasizes core literacy-oriented development, focusing on nurturing versatile talents with design thinking, technological application skills, and innovative spirit. For curriculum design, it advocates constructing a course system integrating foundational, core, and advanced courses. In teaching practice, it promotes project-problem-design-based comprehensive practical activities to overcome the isolation of traditional teaching methods, thereby enhancing students' comprehensive abilities and innovation literacy. This research aims to offer reference pathways for talent cultivation in design arts and provide practical support for the theoretical development of STEAM education.
