Cross-border higher education offers significant opportunities for knowledge sharing, global citizenship, and institutional cooperation, yet it is hindered by systemic barriers such as misaligned accreditation systems, cultural differences, language challenges, and uneven digital infrastructures. This paper argues that Constructive Alignment (CA), a framework aligning Intended Learning Outcomes, Teaching and Learning Activities, and Assessment Tasks - can serve not only as a pedagogical methodology but also as a lingua franca for international collaboration. Building on experiences from Erasmus+ projects, we show how CA enables the design of modular, portable, and adaptable educational units that transcend institutional and national boundaries. The proposed workshop engages participants in redesigning fragmented course materials into constructively aligned units, simulating their adaptation across diverse contexts. By combining theoretical input with hands-on exercises, the workshop equips educators, curriculum designers, and project coordinators with practical tools to overcome systemic and cultural fragmentation. Expected outcomes include enhanced curriculum portability, transparent assessment practices, and the strengthening of international collaboration networks. Ultimately, this contribution positions CA as a cornerstone for inclusive, flexible, and sustainable cross-border education, fostering longterm impact at the participant, institutional, and ecosystem levels.
