Business Process Model and Notation (BPMN) is a standard formalism for business process modeling that is very popular in professional practices due to its expressiveness, the well-defined meta-model, and its easiness of use by non-technical users. For instance, BPMN2.0 is used for business processes in commercial areas such as banks, shops, production, and supply industry. Due to its flexible notation, BPMN is increasingly being used in non-traditional business process domains like education. The presented research work aims to develop a valid extension by applying the BPMN representation of pedagogical scenario in connectivist cMOOC context. BPMN provides a set of generic process modeling elements that make it necessary to extend the language and notation by domain-specific concepts from connectivist pedagogical approach. Therefore, BPMN2.0 extensibility mechanism was explored to include the representation of specific cMOOC pedagogical concepts. Moreover, this paper provides an analysis of the requirements of those concepts. Based on a cMOOC-oriented pedagogical scenario model, the need for an extension is identified and the valid BPMN extension meta-model is designed by the construction of a conceptual domain-specific model and the corresponding BPMN extension model.
