The study—conducted by SRI Education and rpk GROUP and released at Achieving the Dream’s 2020 DREAM conference here today—found that students enrolled in OER courses earned more credits than non-participating peers and that the effort was cost-effective not just for students but for institutions. Students at the participating colleges saved $10.7 million on the cost of learning materials. As courses became established, institutions were in position to recover their costs or even, in some instances, generate income from the effort as more students signed up for the OER courses.
