Adaptive Learning Environment Framework

In this paper the Adaptive Learning Environment Framework is presented. This Framework allows to re-use, combine, and improve existing learning systems or knowledge-databases and equip the resulting meta-learning environment with a new advanced user interface. Especially the last mentioned feature supports a completely new way to learn different materials from different sources without having to switch between systems. The introduction of an abstraction layer between different learning environments and the introduction of different views on the contained learning material allows to combine, extend, and improve available learning systems easily.
