“…DEVELOPING WITH THE USE OF PETRI NETS It is possible to present the relation of subunits and courses in our model as a Petri net. Several examples can be found in the papers when Petri nets have been used in the modeling of learning systems [3,4]. For example Petri nets are used in order to optimize learning paths to reach a degree or a qualification [5].…”

This article proposes new approach to the development of student’s individual learning path (ILP). The result of student’s learning is defined as a set of competencies levels. The use of the multi-level system of generalized professional competencies allows to model ILP effectively and to automate the development of an optimal ILP. Each competency level in our model introduces some substantial units called subunits. The process of learning is a sequence of transitions from one student’s state to another through a study of one or more courses. It is possible to present the relation of competency levels and courses in our model as Petri net. Using the Petri net model it is possible to automatically generate the individual learning path including the courses that the student needs to attend according to the set of certain competency levels. For searching of an optimum individual learning path we use algorithm based on tree of reachability for Petri net. The developed model and algorithm were used in the prototype of the information system for automating the construction of individual learning paths. The developed information system may be used for the construction of individual student's learning paths in educational institutions of higher education

“…It is already possible to find some works within e-Iearning literature that are based in Petri nets, like systems where the teacher becomes the main element acting at the core of the educational process [3], model a study course [4] or using high level Petri nets to reuse and aggregate learning resources in e learning [5].…”

In this work a model for an e-Iearning system is proposed for managing a dynamic educational system that, in addition to supervise the students' evolution throughout the course, allows the student to elaborate his/her study plan. The system has two distinct phases. The first phase where the student can visualize all the paths (sequences of modules) in which he/she can obtain his/her qualification, and select which one has the better fit with his/her requirements. The second phase allows the management of the student's evolution obtaining his/her qualification. For this purpose, models expressed in High-Level Petri nets are used, to model each module, as well the entire study plan interdependencies. This paper focuses mainly in the first phase, relying on the construction of the state space associated with the Petri net model of the study plan. The analysis of the generated state space is used to obtain all possible sequence of modules according with desired goals. Applying a set of queries to these results, students are able to obtain information on possible sequences of modules accomplishing his/her goals and requirements and select the best option.

Abstract. This work proposes an approach for course modeling using Petri nets. The proposed modeling method can be applied to support development of e-learning platforms (namely learning management systems -LMS) allowing student guidance when considering reaching a specific goal. This goal could be as simple as getting a set of sequential courses (or a degree), or as complex as combining different modules from different courses having different types of dependencies in order to obtain a qualification. Each course is characterized by a set of modules and their relations. Each module is represented by a Petri net model and the module structure representing the course's dependency relations is translated into another Petri net model. Additional courses or modules can be included into the offer as their associated Petri net models can be easily composed using net addition operation. The contribution of this paper foresees the usage of common Petri nets analysis techniques (such as state space analysis, invariants, trace finding) to constraint student's options in order to optimize his/her path to reach a degree or a qualification. A simple example considering a scenario with a few courses and modules is used to illustrate the approach.
