The document presents an adaptive unit of learning, called "The Dangerous Knowledge Tour", which cumulates two novelties. On the one hand, the adaptive processes were modelled with the IMS-LD authoring tool Recourse at level B. On the other hand, it provides the first example of an adaptive sequencing based on a combination of cognitive and metacognitive formative tests. From a technical viewpoint (IMS-LD for adaptation) and from an instructional viewpoint (combination of learning and metalearning factors in assessment), the Dangerous Knowledge Tour (Verpoorten & Glahn, 2010) provides an up-and-running instantiation of a next generation assessment. However, the instructional design efforts highlighted shortages and drawbacks regarding IMS LD and QTI spécifications.
