Open Educational Resources (OER) are “teaching, learning, and research resources that reside in the
public domain or have been released under an intellectual property license that permits their free use and
re-purposing by others. Open educational resources include full courses, course materials, modules,
textbooks, streaming videos, tests, software, and any other tools, materials, or techniques used to support
access to knowledge” (William and Flora Hewlett Foundation).

OER are characterized by the “5R permissions,” which grant the ability to:
• reuse
• revise
• remix
• retain; and
• redistribute
One important implication of these permissions is that OER are freely available (i.e. without an accompanying need to pay royalties or licence fees).
