To thrive in a globalised world, university graduates need intercultural competences. Studying in higher education provides plenty of opportunities to engage students in interactions across differences found in a multicultural university environment. However, using these interactions as a resource for learning requires careful facilitation. In this chapter, we combine our expertise in intercultural competence development and educational sciences to support the intentional implementation of collaborative learning within internationalised curricula in the multicultural campus. Based on the Group Learning Activities Instructional Design (GLAID) framework, we provide a step-by-step approach to design, develop and implement educational material to support lecturers in all disciplines in designing collaborative learning activities that foster intercultural competence in higher education students. We will illustrate each step of this process with practical examples from different programmes and disciplines within a Dutch university of applied sciences, holding a multicultural student population.
