The objective of study was education system options such as Moodle. Education systems offer many activities with various procedures for implementation within a course. The benefit is an advantage of the relatively large variety of options, but the question stands on their utility and complexity of implementation. For the evaluation of individual activities, they must accept the dynamic and diverse needs of students. A good starting point is the variety of teaching materials and the addition of such activities such as Database, Glossary, or Link to file or web. An analysis of these options is realized by Petri Nets with support simulation. The profit is the availability of an additional analysis with an incidence matrix and reachable markings. Realized analysis confirms a less important of Database and Glossary activities compared with Link to file or web, or Test.
