This paper offers insights into innovative practice being undertaken in higher architectural and design education, where both language and content teaching and learning are integrated as interwoven parts with joint curricular roles. Using Expansive Learning Theory as an analytical framework to examine potential tensions and contradictions arising from the educational approach of Content and Language Integrated Learning, reference is made to three very recent pilot studies of the EU funded project, ARCHI21. The experiential learning in these studies adopted a blended approach, where classical face-to-face learning-teaching scenarios were supported by immersive 3D virtual environments together with social networking media and Web 2.0 tools. This paper uses these pilot studies to speculate on aspects of fragility and offers reflection on future project activity.
