The evaluation of educational service integration in integrated virtual courses

The effectiveness of integrated virtual courses is determined by factors such as the navigability of the system. We argue that in a virtual course, which offers different educational services for different learning activities, the integration of services is a good indicator for the effectiveness of a virtual course infrastructure. We develop a set of metrics to measure the degree of integration of a virtual course. We combine structural metrics and the analysis of the student usage of the system in order to measure integration.
