Knowledge Flows in a Learning Process: the DDK Model

This paper introduces the DDK (“Distributed & Dynamic Knowledge”) model, i.e. a theoretical and practical tool for describing and understanding technology-enhanced learning processes. The model focuses on the knowledge flows that take place within an experience, involving the various actors: teachers, learners, outside experts of various kinds, etc. A graphic rendering, “DDKmorphology” is proposed, to allow at a glance understanding of the knowledge flows that characterize a learning process. The main argument of this paper is that DDK (and the corresponding morphology) is a powerful way to describe, understand and design technology-based educational experiences.
