One college’s use of an open psychology textbook

The high cost of textbooks is of concern not only to college students but also to society as a whole. Open textbooks promise the same educational benefits as traditional textbooks; however, their efficacy remains largely untested. We report on one community college's adoption of a free online psychology textbook. During the fall semester, 2011, 690 students used this book. Compared to students using a traditional text in the spring of 2011, students who used the free online textbook scored higher on departmental final exams, had higher GPAs in the class and higher retention rates.
