Opening the Curriculum: Open Educational Resources in U.S. Higher Education, 2014 - Elaine Allen and Jeff Seaman, OnlineLearningSurvey

Awareness and adoption of open educational resources (OER) has yet to enter the mainstream of higher education. Most faculty remain unaware of OER, and OER is not a driving force for faculty decisions about which educational materials to adopt. The picture does include some promising signals, as results show that faculty find the concept attractive: those who are aware of OER rate it roughly on par with traditional resources, and those who have not yet used it are very willing to give it a try https://files.eric.ed.gov/fulltext/ED572730.pdf
