Open Educational Resources allow educators to create online customized materials for classes that can be freely shared with other instructors and faculty while at the same time keeping textbook costs low for students. They allow faculty across institutions to collaborate in teaching and learning in addition to enriching the education literature. These materials can be curriculum-based like syllabi or content modules, tangible items like textbooks or assignments or simply collections of pertinent journals or images.
NCLIVE, the North Carolina statewide library database, has created an initiative called Open Education North Carolina which is promoting OER across both public and private institutions in North Carolina.
Canvas also has an OER program which may be of interest; in addition, see the OER Commons for more information.
