摘要:Textbook costs can have a significant impact on the purchasing behaviors and academic success of higher education students. Open textbooks promise significant cost savings, yet perceptions about quality and efficacy still linger. This study explored the impact of an open textbook adoption in an American history course on student academic outcomes and behaviors. Using a mixed-methods design, significant savings were realized with no decrease in student academic outcomes. Further, students reported having a positive experience using the open textbook, perceived the textbook as being of high quality, and expressed gratitude about the free cost. The authors describe the respective roles of the librarian/instructional designer team and note the importance of working collaboratively with instructors to ensure successful implementation of open textbook adoptions.
