Using open educational resources (OER) provides several benefits: OER are free to use and openly licensed, allowing users to access, reuse, and redistribute them. However, not all online educational resources are open or have a Creative Commons license. While OER avoid copyright restrictions and permissions, users must be careful as Creative Commons licenses are non-revocable and works will remain available even if the license is later changed. Finding high-quality, relevant OER may require searching through multiple resources online.
