What are Open Educational Resources (OER)?
OER are educational materials that are specifically designed by their creator/s to be openly available.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.
