This review provides a summary of all known empirical research on the impacts of OER adoption (including our own). The version below will be periodically updated with new articles as we become aware of them... We have gathered articles that focus on the efficacy of OER or teacher/student perceptions of such resources in actual practice. We have limited our studies to those in which OER were the primary learning resource(s) and were compared against traditional learning resources; in addition, the study needed to include at least 50 participants.

Given the recent interest in open educational resources, the research landscape in this field is constantly changing. We've compiled a selective list of articles covering a variety of OER-related topics. Articles have been divided into three categories: impact, cost savings, and creation and publication.

The purpose of this case report is to examine open-source textbook adoption through the COUP framework (costs, outcomes, use, and perceptions) comparing a semester with a commercial textbook to a semester with an open-source textbook... Results indicated that although costs were substantially lower, student learning outcomes and perceptions of quality were similar or better with an open-source textbook.

Florida Virtual Campus. (2012). 2012 Florida Student Textbook Survey. Retrieved from http://www.openaccesstextbooks.org/pdf/2012_Florida_Student_Textbook_Survey.pdf.
Florida Distance Learning Consortium (FDLC) conducted a revised survey of higher education students between January 18 and April 4, 2012 as a follow-up to the 2010 Florida Student Textbook Survey. FDLC administered the earlier survey in response to the Open Access Textbooks Task Force Report (2010). The task force report was pursuant to a 2009 charge by the Florida Legislature to develop a plan for promoting and increasing the use of open access textbooks as a method for reducing textbook costs (Section 1004.091(2), Florida Statutes). The online survey of Florida higher education students was conducted to learn more about some of the issues underlying textbook costs and alternative solutions.
Florida Virtual Campus. (2016). 2016 Florida Student Textbook & Course Materials Survey. Retrieved from http://www.openaccesstextbooks.org/pdf/2016_Florida_Student_Textbook_Survey.pdf
The survey examined textbook affordability and acquisition at Florida’s public higher education institutions. Previous surveys were conducted in 2010 and 2012. In this survey, students were asked to use their recent personal experiences to provide insight on how the cost of textbooks and course materials impact their education, purchasing behaviors, academic completion and success, the study aids they find most beneficial to their learning, and their use of financial aid to address these costs.
