Introduction to OER

Open Educational Resources (OER) are teaching, learning, and research materials that are accessible online at no cost or at a low cost, and that are licensed in a way that allows reuse, modification, and redistribution. They are designed to support teaching and learning across diverse contexts, from classrooms to informal study environments. This article explores what OER are, why they matter, and how they can be implemented effectively.

What is OER?

Definition of Open Educational Resources (OER)

OER are teaching, learning, and research resources that are freely available for anyone to use, adapt, and share. They can include full course curricula, lecture notes, assignments, assessments, multimedia, and other learning objects. The defining feature of OER is that access and reuse are enabled by open licenses that permit broad use beyond traditional copyright, removing barriers to education.

Key characteristics: free access, open licenses, and modifiability

Three core characteristics distinguish OER from other materials. First, free access means learners and educators can obtain resources without financial barriers. Second, open licenses—such as Creative Commons licenses—clarify permissions and conditions for use. Third, modifiability allows educators to adapt and remix materials to fit local contexts, cultures, and learning goals.

• Free access to high-quality materials
• Open licenses that grant permissions for reuse, remix, and redistribution
• Permission to adapt materials to meet local needs

Why OER Matters

Increases access and reduces costs for learners

OER reduce or eliminate the costs associated with textbooks and course materials, which can be a significant barrier for many learners. By providing openly licensed resources, students gain affordable or free alternatives that support sustained engagement throughout a course or program. This accessibility helps widen participation and improves completion rates in many settings.

Promotes equity across diverse contexts

OER are adaptable to varied languages, cultures, and educational levels. By allowing educators to tailor materials, OER support inclusive practices and ensure materials reflect local realities. This adaptability helps learners from underrepresented or marginalized communities access relevant, culturally resonant resources.

Encourages collaboration and continual improvement

Because OER are openly licensed, teachers, institutions, and communities can collaborate to improve resources over time. Modifications can be shared back with the wider community, creating a feedback loop that accelerates quality enhancements and keeps content up to date with current research and practice.

Benefits of OER for Educators and Institutions

Cost savings and flexibility to adapt materials

OER reduce expenditure on textbooks and proprietary materials. Institutions can reallocate funds to support faculty development, student services, or infrastructure. The flexibility to adapt resources means educators can align materials with learning outcomes, assessments, and local standards without seeking permission from multiple publishers.

Faster updates and customization to local needs

With open licenses, updates can be implemented quickly in response to new research, changes in curricula, or local requirements. Institutions can customize content for different courses, programs, or campuses, ensuring consistency while preserving locally relevant nuances.

Supports inclusive education through accessible formats

OER can be produced in multiple formats—text, audio, video, captions, and alternative text—making learning accessible to a wider range of students. When designers consider accessibility from the outset, OER become a practical vehicle for inclusive education across diverse learning needs.

Licensing and Rights

Open licenses (e.g., Creative Commons) and what attribution entails

Open licenses, such as Creative Commons (CC), specify what can be done with a resource and under what conditions. At a minimum, many licenses require attribution, meaning users must credit the original creator. Some licenses also permit commercial use or derivative works, while others restrict adaptations to non-commercial uses or require share-alike terms.

Permissions for modification, remixing, and redistribution

One of the core advantages of OER is the ability to modify, remix, and redistribute materials. Licenses that allow adaptations enable educators to tailor content to language, cultural relevance, and local pedagogy. Redistribution ensures improved versions can propagate widely, benefiting a larger audience while maintaining clear provenance and licensing terms.

OER in Practice

Finding high-quality OER resources

Finding reliable OER begins with trusted repositories, library catalogs, and institutional repositories. Look for materials that are clearly licensed, well-documented, and aligned to learning objectives. Repositories that provide metadata, version histories, and usage guidance help educators select suitable resources quickly.

Evaluating quality, accessibility, and relevance

Quality assessment for OER involves examining accuracy, currency, alignment with standards, and peer review when available. Accessibility involves ensuring materials are usable by people with disabilities, including compatible formats, captions, and navigable structures. Relevance requires assessing whether content aligns with course outcomes, student needs, and local context.

Citing and tracing source materials

Even when using open resources, proper citation remains important. Tracking original authors, licenses, and edition versions helps maintain intellectual honesty and enables others to trace provenance. Clear attribution also demonstrates respect for creators and supports ongoing collaboration within the OER ecosystem.

Implementation Roadmap

Assess needs and readiness

Begin with a needs assessment to identify learning materials that could be replaced or enhanced with OER. Assess institutional readiness, including licensing policies, faculty expertise, and the availability of support for content adaptation. Establish clear goals, success metrics, and timelines to guide the rollout.

Pilot projects and stakeholder buy-in

Start with focused pilots in a few courses or departments to test workflows for locating, adapting, and citing OER. Involve faculty, librarians, instructional designers, and students early to build buy-in and address practical challenges. Use pilot results to refine processes and demonstrate value.

Scale sustainably with governance and quality checks

When expanding, implement governance structures that define roles, licensing compliance, and quality assurance. Develop review cycles for updates, accessibility checks, and student feedback. Sustainable scaling relies on ongoing professional development, partnerships, and mechanisms to share best practices across the institution.

UNESCO highlights that OER reduces cost barriers and increases access to quality education

UNESCO emphasizes that Open Educational Resources expand access to quality education by removing cost barriers and enabling adaptable, culturally relevant materials. This aligns with global goals to broaden participation and improve learning outcomes across diverse contexts.

Policy support, licensing clarity, and capacity building are key to scaling OER

Policy frameworks, clear licensing terms, and capacity-building initiatives are identified as essential levers for scaling OER. When institutions and governments invest in these areas, the adoption and impact of open resources can be sustained at scale.
