The five research questions addressed the relationship between textbook and reviewer characteristics and ratings. Although reviewers gave textbooks high ratings generally, reviewers identified differences in quality according to criteria and discipline. Physics and chemistry textbooks earned significantly lower ratings than other textbook types. Ratings were not significantly associated with reviewers’ status and experience, but were associated with reviewers’ place of residence. We discuss the implications for OER efficacy studies and other research. %8 06/2017 %9 Special Issue: Outcomes of Openness: Empirical Reports on the Implementation of OER %@ 1492-3831 %* yes %> https://www.oerknowledgecloud.org/archive/2985-24057-1-PB.pdf
