Open educational resources

Open educational resources (OER) are teaching, learning, and research materials that are intentionally created and licensed to be free for the end user to own, share, and in most cases, modify. The term "OER" describes publicly accessible materials and resources for any user to use, re-mix, improve, and redistribute under some licenses. These are designed to reduce accessibility barriers by implementing best practices in teaching and to be adapted for local unique contexts. Enabling these rights in practice may require the availability of source files, the editable formats from which final resources are derived, leading by extension to the proposed notion of "" (OSER).

The development and promotion of open educational resources is often motivated by a desire to provide an alternative or enhanced educational paradigm.
