The use of learning management systems gives rise to many difficulties for teachers and instructional designers in terms of designing their courses. These difficulties are mainly related to the operationalisation of pedagogical scenarios and the use of the corresponding tools, especially in a connectivist context. The work presented in this paper focuses on learning design models for massive open online course (MOOC) environments, and more specifically on assisting teachers in the design and implementation of pedagogical scenarios for connectivist MOOCs (cMOOCs). The major contribution of this work is a visual authoring tool, based on business workflows for the design and deployment of cMOOC-oriented scenarios on the Moodle platform. The tool was also evaluated, primarily from the point of view of utility and usability. The findings confirm that our tool can provide all the elements needed to formalise and operationalise such courses on the Moodle platform
