Definition and meaning
Open educational resources (OER) are teaching, learning, and research materials that are freely available for anyone to use, adapt, and redistribute. OER include textbooks, course materials, videos, lesson plans, and assessments released under open licenses such as Creative Commons. The OER movement aims to reduce barriers to quality education by making materials accessible regardless of geography or financial means. Organizations and universities worldwide contribute to and maintain large repositories of OER.
