Open educational resources

Open educational resources (OER) are teaching, learning, and research materials intentionally created and licensed to be free for the end user to own, share, and in most cases, modify. The term "OER" describes publicly accessible materials and resources for any user to use, re-mix, improve, and redistribute under some licenses. These are designed to reduce accessibility barriers by implementing best practices in teaching and to be adapted for local unique contexts.

The development and promotion of open educational resources is often motivated by a desire to provide an alternative or enhanced educational paradigm.

Open educational resources (OER) are part of a "range of processes" employed by researchers and educators to broaden access to scholarly and creative conversations. Although working definitions of the term OER may vary somewhat based on the context of their use, the 2019 definition provided by UNESCO provides shared language useful for shaping an understanding of the characteristics of OER. The 2019 UNESCO definition describes OER as "teaching, learning and research materials that make use of appropriate tools, such as open licensing, to permit their free reuse, continuous improvement and repurposing by others for educational purposes."

While collaboration, sharing, and openness have "been an ongoing feature of educational" and research practices "past and present", the term "OER" was first coined to describe associated resources at UNESCO's 2002 Forum on Open Courseware, which determined that "Open Educational Resources (OER) are learning, teaching and research materials in any format and medium that reside in the public domain or are under copyright that have been released under an open license, that permit no-cost access, re-use, re-purpose, adaptation and redistribution by others."

Often cited is the 2007 report to the William and Flora Hewlett Foundation which defined OER as "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 or 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." The Foundation later updated its definition to describe OER as "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." Of note in that definition is the explicit statement that OER can include both digital and non-digital resources, as well as the inclusion of several types of use that OER permit, inspired by 5R activities of OER. In a 2022 overview of the William and Flora Hewlett Foundation's activities supporting open education since 2002, the Foundation describes OER as "freely licensed, remixable learning resources", further including the Creative Commons definition of OER as "teaching, learning, and research materials that are either (a) in the public domain or (b) licensed in a manner that provides everyone with free and perpetual permission to engage in the 5R activities – retaining, remixing, revising, reusing and redistributing the resources."

The 5R activities/permissions mentioned in the definitions above were proposed by David Wiley, and include:

Authors, creators, and communities may apply a range of licenses or descriptions such as those facilitated by Creative Commons or Local Contexts | TK Labels to their work to communicate to what extent they intend for downstream users to engage in the 5R activities or other collaborative research, creative and scholarly practices.

The Organisation for Economic Co-operation and Development (OECD) defines OER as: "digitised materials offered freely and openly for educators, students, and self-learners to use and reuse for teaching, learning, and research. OER includes learning content, software tools to develop, use, and distribute content, and implementation resources such as open licences". By way of comparison, the Commonwealth of Learning "has adopted the widest definition of Open Educational Resources (OER) as 'materials offered freely and openly to use and adapt for teaching, learning, development and research'". The WikiEducator project suggests that OER refers "to educational resources (lesson plans, quizzes, syllabi, instructional modules, simulations, etc.) that are freely available for use, reuse, adaptation, and sharing'. Institutions emphasizing recognition of work with open educational resources in faculty promotion and tenure emphasize their use in research, scholarly and creative works as well.
