Open educational resources (OERs) are freely available teaching and learning materials that can be reused, modified, and shared. OERs offer several benefits such as reducing student costs by replacing traditional textbooks, allowing for quick updates and improvements, and providing scalable and accessible learning materials to students worldwide. However, some challenges to OERs include lack of incentives for continued creation, insufficient training for educators, potential language barriers, requiring internet access and technological capabilities, and missing the human interaction of in-person classes.
