Developing and delivering curricula that are integrated and that use blended learning techniques requires a highly orchestrated design. While institutions have demonstrated the ability to design complex curricula on an ad-hoc basis, these projects are generally successful at a great human and capital cost. Model-driven design provides a sustainable approach that reduces some of the cost of complex curriculum development and improves the sustainability of curriculum innovation. Systems thinking is a perspective for going beyond events, to looking for patterns of behavior, and to seeking underlying systemic interrelationships which are responsible for the patterns of behavior and the events. Model-driven design provides the ability to share models and learning units beyond the borders of the institution. (Contains 3 tables and 7 figures.)
