Open Education is an attitude, a practice, and a method of learning and teaching that inspires inquiry, equal access to course materials, and sharing lessons and materials with the broader community (Community College Consortium for OER).
To realize those objectives, OER (Open Educational Resources) refers to “teaching, learning and research materials in any medium — digital or otherwise — that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation, and redistribution by others with no or limited restrictions” (UNESCO).
Likewise, OEP (Open Educational Practices) refers to both the use of OER materials in addition to a dedication to “open pedagogy and open sharing of teaching practices — all with the goal of improving access, enhancing learning, and empowering learners” (National Forum for the Enhancement of Teaching and Learning in Higher Education).
