Open Educational Resources (OER) for Faculty

Abstract-Open Educational Resources (OER) remove barriers to access instructional material. In light of their increased availability and use, a body of research has emerged to examine the impact of OER on college student success. While many of these studies have broadly examined efficacy across a variety of disciplines, the current study specifically examined the impact of the type of textbook (commercial vs. OER) on course content mastery within an undergraduate sample of introductory psychology students (N = 63) while controlling for instructor and student differences. Results indicated that there were no significant differences in content mastery between those students in introductory psychology courses who were assigned a traditional commercial textbook and those who were assigned an OER textbook. These results support that OER can be equally effective as traditional, commercial textbooks and have implications for course material selections that help ensure access for all students.

Abstract-In the current study we examined students' course performance, perceptions, and self-reported use of an open textbook compared to a traditional publisher's textbook in an introductory psychology course. Sixty students from two course sections used either an open textbook or a traditional textbook. To minimize the effect of confounding variables, each section was taught by the same instructor, at the same time of day, using identical in-class materials, syllabi, and sequencing, on alternating days of the week. Course performance was measured by analyzing exam scores and final course grades. A 22-item survey was utilized at the end of the term to measure students' textbook perceptions and use. Findings revealed no significant differences in student course performance or textbook use across the two sections. Participants in both groups perceived cost, weight, and convenience as the biggest advantages of an open textbook and perceived ease of reading, convenience, ability to highlight and take notes, ability to quickly find a topic, and ability to keep as a reference as the biggest advantages of a traditional textbook. Finally, when asked to select which type of textbook they preferred, students in each section selected the textbook they were using. The implications of these findings are discussed.

A summary of all known empirical research on the impacts of OER adoption.

Abstract-The bulk of previous research on students' perceptions of open educational resources have lacked a control group of students rating traditional textbooks. Moreover, few studies have examined differences in the perceptions of online students and those taking classes in the classroom. A 2 × 2 cross-sectional design was used in which 925 students, assigned either a traditional textbook or an open textbook in either an online or classroom environment, were recruited to complete an online survey. Students assigned open textbooks were almost twice as likely to report using their textbooks, they used them more frequently, and for more time per week overall. Students assigned open textbooks also perceived a greater degree of overlap between the textbook, lecture, and quiz material than did students assigned traditional textbooks. Finally, ratings of the open textbooks were significantly higher than ratings of the traditional textbooks overall and on 11 of 15 different dimensions. Few differences in the online and classroom students were detected, suggesting both groups experienced similar benefits of the open textbooks. These findings demonstrate that replacing traditional textbooks with open textbooks may help to offset some of the financial hardships students face while improving students' engagement and satisfaction with their assigned textbook.

Abstract-Open educational resources (OER) are increasingly attractive options for reducing educational costs, yet controlled studies of their efficacy are lacking. The current study addressed many criticisms of past research by accounting for course and instructor characteristics in comparing objective student learning outcomes across multiple sections of General Psychology taught by trained graduate student instructors at a large research-intensive university. We found no evidence that use of the OER text impeded students' critical thinking compared to use of a traditional textbook, even after accounting for instructor characteristics. To the contrary, we found evidence of a slight increase in content knowledge when using an OER text. Importantly, this effect was driven by improvements from both our lowest-performing students and our highest-performing students. Moreover, student learning outcomes were not influenced by instructor experience, suggesting even novice instructors fared well with OER materials. Finally, students from traditionally underserved populations reported the lower cost of the book had a significantly higher impact on their decision to enroll in and remain enrolled in the course.
