peri nets, elearning, model, course

The basic component of modern elearning systems is usually a course. This virtual learning unit corresponds with an existing educational process, or at least with one of its parts. A course is understood as a collection of individual objects which represent the subject matter, perform feedback activities or diagnostic testing. Individual objects are grouped into partial units which correspond with partial presence educational activities. If specific relations between objects, or partial units, are defined, there is a need for a good design of the learning course. The objective of a relation is to apply a high level of individual approach and adaptive mechanisms while keeping the quality of the learning course outcome. Those are the aspects that direct to the use of modelling tools in the area of elearning courses to develop quality courses. This paper is devoted to the possibilities of using the Petri nets, hereinafter PN, for such modelling.
