Research on OER impacts are not confined to cost savings estimates.  There is a growing body of knowledge and research about the impacts OER have on student outcomes.  Studies look at student satisfaction, engagement and outcomes as measured by completion, retention, drop/failure/withdrawal rates, and grades.  There are large scale studies and class level case studies at various types of post secondary institutions.  Some of this research has even been incorporated into a OER Adaption Impact Calculator.  The Open Education Group, a grant funded organization devoted to enhancing open education, had developed a framework for understanding the impact of OER

Listed here are only a few such studies with links to a feed for new papers.
