Textbooks are a crucial part of higher education. High-quality textbooks authored by experts provide a coherent curriculum for teaching and learning. However, the increasingly high cost of commercial textbooks is a serious problem. Many students cannot afford to buy expensive required textbooks. Faculty and administrators concur that high cost is the primary reason that not all students have access to course materials. Increasingly, studies show that using free, open textbooks can be as good or better than commercial textbooks, but there are opposing opinions and strong emotional reactions to open textbook adoption, adaptation, and creation. In this facilitated conversation, participants will engage in a crucial conversation about open textbooks that is inclusive of diverse perspectives and works towards deeper understanding of this controversial topic. Through an interactive roundtable discussion format, participants will discuss: What forces are driving change in the post-secondary sector towards open textbook use? Do open textbooks exist or suit your teaching contexts? What tensions result when we are asked to change our existing pedagogical approaches and technologies? Are they worth the extra time and effort to make them successful?
