This chapter can be assigned to the main fields of new and innovative educational paradigms and learning models, innovative modes of teaching and learning based on technological capabilities and strengths and weaknesses of technologies as effective teaching tools. It covers the construction of e-learning materials using a modular design approach in order to meet the technical and didactical requirements for the optimum operation of distance learning scenarios. First, it addresses the development path and substantial deficits of conventional e-learning materials. After this, it gives an overview of the requirements the supplier thinks necessary to develop high quality and state-of-the-art e-learning materials. In the following section, the customer’s needs with regard to the e-learning materials will be addressed. Accommodating both parties and securing high quality requires a high flexibility for configuration of a Web-based learning and teaching environment. The next section introduces the respective concept based on modular structures. The content-related design of study modules will be shown with the support of an example taken from the education network WINFOLine.
