This paper explores how AI-powered tools foster cross-border cooperation, enabling educators to co-create meaningful learning experiences. As part of ASEFClassNet17, teachers from Singapore, Austria, and Australia used AI tools like Brisk Teaching, Magic School AI, Suno, and InVideo to develop a climate change education initiative. Their experiences highlight AI’s potential to break barriers, enhance creativity, and support multicultural collaboration. However, success depends on teacher expertise, thoughtful instructional design, and ethical considerations. While AI-driven learning empowered students, challenges emerged: Uneven policies affected adoption, with Singapore’s structured AI governance providing clarity, while Austria and Australia faced uncertainty. Aligning AI with Industry 5.0 values, this study underscores AI’s role as a powerful assistant—but not a substitute for human creativity and cultural exchange.
