Textbook Alternatives & Open Educational Resources (OER)
"The OpenCourseWare Consortium is a collaboration of higher education institutions and associated organizations from around the world creating a broad and deep body of open educational content using a shared model."
"Our mission is to expand access to education by promoting awareness and adoption of Open Educational Resources (OER). Over 100 colleges are members of our consortium and many more participate in our activities and use the resources posted here."
"This review provides a summary of all known empirical research on the impacts of OER adoption (including our own). The version originally published here in February 2015 was abstracted from of an article submitted for publication in a peer-reviewed journal."
