Open education resources (OER) are teaching and learning materials that are freely available online for anyone to use and adapt. OER include textbooks, videos, images and other materials that are licensed openly to be reused without permission. Using OER provides students with free access to up-to-date learning materials through any technology. It benefits educators by offering alternatives to expensive textbooks and opportunities for collaboration. However, both students and educators face challenges such as lack of access to technology, distraction from other course responsibilities, and the need for careful planning to implement OER effectively. Overall, OER increase access to education and opportunities for creative work.
