Led by John Hilton III, this review provides a summary of all known empirical research on the impacts of OER adoption. It is updated as new studies are conducted.
As Hilton (2016) asks: “Because students and faculty members generally find that OER are comparable in quality to traditional learning resources, and that the use of OER does not appear to negatively influence student learning, one must question the value of traditional textbooks. If the average college student spends approximately $1,000 per year on textbooks and yet performs scholastically no better than the student who utilizes free OER, what exactly is being purchased with that $1,000?”
