The principles and techniques of the task-centered instructional design will be introduced and practiced in the hands-on group work that involves creating, sequencing and validating authentic instructional tasks. A special focus will be on mapping the instructional tasks in MOOC to facts, concepts, procedures and rules identified in the course objectves, as well as scaffolding the learning through well-designed course assignments and learning resources. This presentation was given during the EMMA Summer School, that took place in Ischia (Italy) on 4-11 July 2015.
