Open (Free) Educational Resources for your Course
Don't reinvent the wheel! In some cases, a good publisher or open "free" educational resources may be available for your particular purpose, and there is no need to design your own. Open Educational Resources (OER) can be all kinds of "learning objects," such as animations, videos, interactive games, PowerPoint presentations, simple documents and more. OER are usually licensed with Creative Commons licenses that grant users specific rights for reuse, remix and distributing content.
