Open educational resources provide several benefits including reducing costs for students and instructors, increasing access for those unable to afford textbooks, encouraging sharing of ideas and materials, allowing for feedback to improve resources over time, and providing a large volume of available materials. Some challenges to open educational resources include ensuring the quality of materials, managing licensing and proper attribution, limited availability for niche courses, the time required to locate and curate resources, and that published textbooks can be more convenient to use for instructing.
