"In January 2013, Leuphana University ventured into global online learning with the launch of Leuphana Digital School's prototype course "ThinkTank - Ideal City of the 21st Century", a cost-and-barrier-free academic platform that offered collaborative web-based learning led by distinguished scholars and experts. This new program introduced a fresh, unique approach to collaborative learning - a university project open to participants from all over the world, regardless of where they live and what they do."
