OER are educational materials that are specifically designed by their creator/s to be openly available, and are often licensed to be re-used, re-mixed, and re-distributed. Open is not just about low cost (though that is an important benefit of using OER) but about the ability to take what others have created, customize it for your specific educational needs, and then share your creation with others. This section holds OER resources created by the Lindenwood community.
