OER Knowledge CloudJournal ArticlePfannenstiel, AmberNicoleRedcay, AlexAlbert, DanielMany Open Educational Resource (OER) and Zero Textbook Cost (ZTC) studies explore cost savings, impact on learning outcomes, and student perceptions of the materials. While OER/ZTC research reports positive student perceptions (Brandle et al., 2019), textbook research reports negative student perceptions of digital textbooks (Behnke, 2018). This study explores student buying behavior and perceptions of textbooks, finding that perceptions toward the usefulness of materials is high when access to materials is high. Given this student perception, textbook purchasing is likely related to outside factors. This study adds to the growing body of research about how OER and ZTC may influence student costs and access to course materials, finding that student attitude toward course materials needs to be considered alongside adoption.20202020/12/31EnglishOpen Praxis124555-567United States10.5944/openpraxis.12.4.11192304-070Xyesopen educational resourceszero textbook cost coursestextbook perceptions110-217-1-SM.pdfUnited States, North America
