. From this perspective, designing an AER system places us in the position of
designing tools for creating games. These tools can be used to create a playground for
teachers that act as artists who create games for learners. Pictorially we create
brushes and colors that are used by teachers to paint pictures that are shown to the
Learner. Thus the challenge is to design tools for the creation of teaching and learning
processes that open up spaces for creative actions. The fact that the contradiction
between compulsory rules and open creativity is unproblematically solved while
actually playing games shows in turn that the association of gaming for teaching and
learning is suitable. We suggest to provide a metadata system, a learner model and a reasoning
engine as tools to create learning environments. The metadata system allows to
describe different possibilities to learn certain content. It is formulated logically in an
ontology in the (Web Ontology Language). The flexible elements are circled around learning pathways.
