When developing the course, the focus was on multimedia resources and practical applications. This research paper highlights the importance of a well-designed MOOC to address the teachers’ digital needs and provides actionable recommendations for the effective application and development of MOOCs in the future. In addition, the results of the study contribute to the literature on professional development and offer ideas for optimizing MOOCs for educational purposes.
