We report on educators' experiences of a massive open online course (MOOC) focused on the Carpe Diem learning design process. The MOOC was developed in-house using Blackboard CourseSites by a university innovation and development unit, Learning Transformations, at Swinburne University of Technology in Melbourne, Australia. We report on a study of MOOC participants' experiences. Conclusions include illumination of MOOCs' value as professional development opportunities that can provide an authentic relevant experience for educators, as well as promote new skills in learning design and delivery for their own teaching. We propose that participation in relevant MOOCs may provide appropriate professional development for academics, and additionally encourage them to develop their teaching practices.
