This paper aims to reflect on internationalisation in social work education in a collaborative context. The research question addressed is how collaborative online international learning (COIL) supports the concept of Internationalisation at Home (IaH) to promote glocal knowledge in innovative social work education. The study is case-based, in which a thematic webinar on human rights issues connected students of social work from various countries in an international classroom. It discusses how the concept of Internationalisation at Home can be used effectively in practice through participatory design and participant feedback. The main conclusion of this case-based paper is that social work education should promote innovative learning scenarios that support the glocal approach, so that students are able to ‘act locally and think globally’, supported by a blended learning design.
