This document discusses the benefits and challenges of open educational resources (OER) compared to traditional textbooks and course materials. The benefits include lower costs for students, increased access and flexibility, opportunities for customization and collaboration among faculty. However, challenges include the difficulty finding high-quality materials, lack of accessibility support, limited review and updating of content, and potential technical issues with online resources that have little support. Overall, OER can improve affordability and preparation for students but implementing and maintaining them takes significant effort from instructors and institutions.
