This paper will be looking into the issue of quality assurance in online learning from the perspective of the e-learning tool developed by the Institute for European Studies in Brussels--the E-modules. The E-modules have been designed with the purpose of offering a structured and interactive way of learning how the European Union functions. As European law and policies exert an important influence in the everyday life of European citizens, the E-modules aim at providing the essential information, helping, at the same time, the users to find their way through the complexity of existing information sources. Therefore, assuring the quality of the content is an essential feature for the developers of the E-modules and, at the same time, a great challenge, taking into account, on the one hand, the complexity of social science and, on the other hand, the quick pace with witch the European Union evolves.
