The Learning Objects Structure Petri Net

The Learning Objects Structure Petri Net, LOSPN describes the structure and mutual dependence of a set of learning objects, LOs. It allows to model the context of each learning object in terms of preconditions (prerequisites) and postconditions (learning objectives or learning targets). It is this property which makes re-use of learning objects in different courses and in different departments possible. The LOSPN offers to derive the level of a learning object from the structure of the set of LOs. It allows to define different learn paths. If a student does not pass a certain LO the LOSPN (without further diagnosis) indicates which LOs should be recapitulated. Our Notebook University project teleVISE provides many examples for LOSPNs: how to generate a LOSPN, how to represent it in XML within standards, and what potential LOSPNs provide.
