Virtual Learning World (VLW) is an e-Learning system, where the Virtual Worlds are used for educational purposes. This paper describes the design and concept of the VLW and shows the "Virtual Car Dealer" (VAH, in German Virtuelles AutoHaus) as one example of it. The VAH has been designed as a complement to German vocational training. It supports the education in the classroom and training in companies. Learners are represented by avatars in VAH. They can interact with objects, use abstract applications and forms and communicate with each other in order to perform car dealer facility's specific tasks like car sales and customer services. The abstract applications are car dealer facility's specific application like inventory, booking and accounting and are used to sustain the state of VAH. Learner can change the state of VAH by using the abstract application. Consequently, the system possesses time variant and dynamic learning exercises.
