The study involved 5,000 students using OER and more than 11,000 “control” students using standard textbooks in courses at 10 different institutions around the country enrolled in 15 different undergraduate courses. It focused on five measures of student success. In the area of course completion, the researchers found “almost no significant differences” between the two groups with a couple of exceptions. In Business 110 and Biology 111 students in the OER group showed higher rates of completion than students in the control. For example, in the business class, 21 percent of commercial textbook users withdrew; in the OER group only six percent withdrew. In the area of student achievement (passing with a C- or better grade), the outcome was mixed. In nine courses researchers saw no significant differences. In five courses, the OER users were more likely to pass the course than those in the control group. In one course, Business 110, students in the control group surpassed students using OER.
