A b s t r a c t : Selecting appropriate learning services for a learner from the large number of heterogeneous knowledge sources is a complex and challenging task. This paper pre s e n t s the idea of Sm a rt Spaces for Learning. A Sm a rt Space for Learning is defined as a distributed system (ie " s p a c e ") that provides management support for the " s m(More)
This paper illustrates how internet-based learning information systems can be used to reengineer undergraduate teaching in the age of mass higher education. We describe current problems of undergraduate teaching by using an example of an introductory course in information technology at the Vienna University of Economics and Business Administration. We argue(More)
Charge movement currents (IQ) and calcium transients (delta[Ca2+]) were measured simultaneously in frog skeletal muscle fibers, voltage clamped in a double vaseline gap chamber, using Antipyrylazo III as the calcium indicator. The rate of release of calcium from the SR (Rrel) was calculated from the calcium transients using the removal model of Melzer, W.,(More)
In order to achieve interoperability among learning repositories, implementers require a common communication framework for querying. This paper proposes a set of methods referred to as Simple Query Interface (SQI) as a universal interoperability layer for educational networks. The methods proposed can be used by a source for configuring and submitting(More)
The paper presents the work of the Elena project. The contribution of this paper is twofold: The first part of the paper elaborates on the notion of learning services. Learning services are differentiated from learning objects and put in the context of web services. A model for learning services is introduced and current limitations of learning object(More)
