1. Open Educational Resources (OER) are digitized materials that can be freely used and reused for teaching, learning, and research. OER provide opportunities to improve access to education. 2. OER offer benefits like lowering costs, improving collaboration, and widening participation. They allow educators to efficiently create new materials and adapt existing ones. Learners gain access to new resources. 3. As educational resources transition from analog to digital formats and from closed to open systems, OER can bridge formal and informal learning and support lifelong learning through connectivity and personalization.
