To truly be considered open, an OER must fit within the 5R’s from David Wiley:
Reuse: Use the content in its unaltered form
Revise: Adapt, adjust, modify, improve, or alter the content
Remix: Combine the original or revise content with other OERs to create something new
Redistribute: Share copies of the original content, revisions or remixes with others
Retain: Keep access to the materials after the learning event
Why use OERs?
Open educational resources give educators the ability to adapt instructional resources to the individual needs of their students, to ensure that resources are up-to-date, and to ensure that cost is not a barrier to accessing high-quality standards-aligned resources (oercommons.org).
Are OERs Helpful?
Several thousand students and faculty members have shared their perceptions across more than a dozen studies that have focused on perceptions of OER. In no instance did a majority of students or teachers report that the OER were of inferior quality. Across multiple studies in various settings, students consistently reported that they faced financial difficulties and that OER provided a financial benefit to them. A general finding seems to be that roughly half of teachers and students find OER to be comparable to traditional resources, a sizeable minority believe they are superior, and a smaller minority find them inferior (Open Education Group Review).
