Students in higher education are facing challenges with paying for their education. Cost of course materials, primarily textbooks, continues to be a financial concern. As a result, students often delay or simply do not purchase the materials they need to perform well in courses. Openly licensed materials are becoming popular because they are free to the student, accessible from the first day of class, and can be modified by the teacher. In this study, an open textbook was co-created by two anthropology faculty with the support of two instructional designers for an introductory anthropology course at a large university in the United States. A survey was given to 1,402 students to gauge satisfaction with the textbook and elicit feedback, and final grades were compared pre- and post- open textbook implementation. In general, student satisfaction was high and poor grades declined. In conclusion, we propose recommendations for those who are interested in implementing more affordable course materials in their anthropology classes.
