This study focuses on the application of AI - Generated Content (AIGC) in the collaborative creation of rural murals for educational purposes. Guided by constructivism and social - cultural learning theory, it constructs a systematic co - creation training framework for teachers, students, educators, and community members in universities and primary/secondary schools. A 12 - week quasi - experimental study was carried out with 30 participants divided into three groups. The experimental group used a four - module AIGC - based training framework, while the control group adopted traditional teaching. Data from pre - and post - evaluation scales, work analysis, and interviews were analyzed by SEM and content analysis. Results show that the experimental group outperformed the control group significantly (P < 0.05) in creative ability, cultural understanding, and teamwork. The use of AIGC tools enhanced creative confidence and promoted cultural recognition. This study innovatively applies AIGC to rural mural co - creation, integrating technology, theory, and cultural rejuvenation. Although the sample size is small and from specific regions, it paves a new way for AIGC in education and cultural practice. Future research should test the framework’s applicability in diverse set-tings, expand the sample size, and extend the research cycle. Overall, AIGC has broad prospects in education and cultural practice.
