IMS LD reusable elements for adaptive learning designs

This paper presents an approach to designing adaptive learning environments based on IMS LD, which separates its elements (i.e. objectives, prerequisites, method, learning activities, adaptive rules, personalization properties, etc.) in order to use them in different Learning Designs and enforce their reusability and exchangeability. Moreover, it briefly presents an authoring tool under development to define adaptive learning designs compliant with IMS LD.
