Open educational resources (OER) are freely accessible, openly licensed, and adaptable for instructional use.
OER include content such as:
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.
Open content is licensed in a way that grants users permission to:
Make, own, and control copies of the content (e.g., download, duplicate, store, and manage)
Use the content in a wide range of ways (e.g., in a class, in a study group, on a website, in a video)
Adapt, adjust, modify, or alter the content (e.g., translate the content into another language)
Combine the original or revised content with other material to create something new (e.g., incorporate the content into a mashup)
Share copies of the original content, your revisions, or your remixes with others (e.g., post a copy of the content online for others to download)
