 Maastricht University (UM) is the youngest university in the Netherlands. Its “Leading in Learning” approach is closely associated with Problem-Based Learning (PBL): students work in small tutorial groups to analyse problems, exchange knowledge, and set their learning goals together. This approach connects education with independent research and collaboration.
