“…In a survey of 127 post-secondary educators, Pitt (2015) reports that 25% said using an open textbook had "enabled innovation or changed their pedagogical approach" (p. 146), but only a few explained in open-ended questions that they had revised an open textbook. From interviews with faculty who have adopted, adapted, or created an open textbook or other OER, Delimont, Turtle, Bennett, Adhikari, & Lindshield (2016) report that 12 out of 13 faculty said they preferred to teach with OER rather than commercial textbooks, and out of those, 11 gave customizability of OER as a reason for their preference. Neither study, however, focuses on how faculty are revising OER, and overall there is little research in the extant literature on the degree to which faculty or students are revising OER, how they are doing so, and what impact this may have on student learning outcomes.…”
