Model-based Pricing of E-learning

As colleges and universities use the internet as a new channel for education, questions arise how to cover development costs and how to set up revenue models for e-learning. Pricing mechanisms and flexible e-learning systems are needed to offer learners differentiated e-learning services and to charge for their usage. In this paper, we propose a graphical price modeling language that can be used for setting up tariffs for e-learning. Furthermore, a portal architecture with workflow support is presented that can be used to integrate a learning provider's existing systems like e-learning, pricing, and grading systems into individualized web applications (portals) for learners, tutors, and administrators.
