Model-driven Transformation and Validation of Adaptive Educational Hypermedia using CAVIAr

Authoring of adaptive educational hypermedia is a complex activity re- quiring the combination of a range of design and validation techniques. we demonstrate how adaptive educational hypermedia can be transformed into caviar courseware validation models allowing for its validation. the model-based representation and anal- ysis of different concerns and model-based mappings and transformations are key con- tributors to this integrated solution. we illustrate the benefits of model driven en- gineering methodologies that allow for interoperability between caviar and a well known adaptive educational hypermedia framework. by allowing for the validation of adaptive educational hypermedia, the course creator limits the risk of pedagogical problems in migrating to adaptive educational hypermedia from static courseware.
