In the latest Think Education podcast, Judith and myself talk to Professor Nigel Healey, Vice President Global and Community Engagement, University of Limerick. Nigel reflects on cross-cultural learning at universities and how we can best support the student experience in this regard. We debated the issue of how universities can balance sustainable and internationalisation strategies and we talked about the need for, versus the value of, travel in international higher education, including a few anecdotes about the benefits of physical mobility and the need to ensure the best return for carbon investment.
