How to Find, Curate, and Use Open Educational Resources Effectively

Open Educational Resources (OER) have fundamentally changed how educators access and share teaching materials. These are freely available learning resources-textbooks, videos, lesson plans, quizzes, and more-that anyone can use, modify, and redistribute under an open license like Creative Commons. But having access to millions of free resources is only useful if you know how to find the right ones, organise them meaningfully, and integrate them into your teaching practice. That’s exactly what this post covers.

What makes a resource “open”? 🔗

Before diving into how to find and use OER, it helps to understand what qualifies a resource as truly open. According to the 2019 UNESCO Recommendation on OER, these are learning, teaching, and research materials in any format that reside in the public domain or have been released under an open license permitting free access, reuse, adaptation, and redistribution. The key distinction is not just that OER are free to access-they also come with legal permissions that allow educators to modify and share them.

David Wiley’s widely cited 5R framework defines the specific permissions that make content truly open: Retain (make and own a copy), Reuse (use the content in various contexts), Revise (adapt or translate it), Remix (combine it with other materials to create something new), and Redistribute (share copies with others). Understanding these permissions is essential before you start working with OER, because the type of Creative Commons license on a resource determines which of these activities you’re allowed to perform.

Finding OER: where and how to search 🔗

The internet is packed with OER, but finding the right resource for your specific teaching needs requires a strategic approach. Here are the most effective methods.

Using Google and general search engines 🔗

Standard search engines like Google are a reasonable starting point. However, you need to be intentional about your search terms. Include keywords like “open educational resources,” “Creative Commons,” or “OER” alongside your subject-specific terms. For example, searching for “Creative Commons biology textbook” will filter results toward openly licensed content. Google’s Advanced Search also allows you to filter results by usage rights, helping you locate materials licensed under Creative Commons.

Google Image Search similarly lets you filter for images with open licenses. This is useful when you need diagrams, infographics, or photographs for your teaching materials without worrying about copyright violations.

Specialised OER search engines and repositories 🔗

While general search engines work, dedicated OER platforms are far more efficient. Here are the most important ones:

OER Commons is one of the largest digital libraries of open educational resources. It allows searching by subject, education level, and material type, and provides advanced filtering options. It also offers tools for creating and remixing OER directly on the platform through its Open Author feature.

Creative Commons Search (now integrated into Openverse) lets you search across multiple repositories for images, audio, and video that carry CC licenses. This is particularly useful for multimedia resources.

OASIS (Openly Available Sources Integrated Search), developed by SUNY Geneseo, is a meta-search tool that searches over 110 different open content sources simultaneously. It is an excellent single-stop tool when you’re not sure which repository might have what you need.

Mason OER Metafinder from George Mason University works similarly, searching across 15+ major OER repositories in a single query.

MERLOT (Multimedia Educational Resource for Learning and Online Teaching) provides a curated and peer-reviewed collection of online teaching materials, which adds a layer of quality assurance that open repositories sometimes lack.

OpenStax, based at Rice University, offers free, peer-reviewed textbooks for high-enrollment undergraduate courses. These textbooks meet quality standards comparable to traditional commercial textbooks and are available under CC BY licenses.

Tips for effective OER searching 🔗

Start by clearly defining what you need. Are you replacing an entire textbook? Looking for a supplementary video? Searching for a single chapter on a specific topic? Your search strategy should match your goal. Begin with broader terms and then narrow down. Browse tables of contents when you find a resource-you may not need the entire textbook, just a chapter or a module. Also, don’t overlook ancillary materials such as lesson plans, assessments, and instructor guides that often come bundled with OER textbooks.

Curation of OER: more than just collecting links 🔗

Finding OER is only the first step. The real value lies in curating them-carefully selecting, evaluating, annotating, and organising resources for a specific educational purpose. Curation is fundamentally different from collection. Collecting is saving resources for personal use; curation involves critically evaluating resources, considering how they fit a specific teaching context, and organising them so others (including students) can benefit.

Selection and evaluation 🔗

Not every free resource is a good resource. When selecting OER, consider these criteria: accuracy of the content, currency (how up-to-date the material is), relevance to your learning objectives, accessibility for diverse learners including those with disabilities, and the license type. A resource with a CC BY-NC-ND license, for example, cannot be modified or used commercially, which limits its flexibility compared to a CC BY license.

Several quality evaluation rubrics exist to guide this process. The Nebraska Department of Education’s OER Toolkit recommends assessing comprehensiveness, organisational flow, cultural relevance, and alignment with your curriculum standards.

Annotation 🔗

Once you’ve selected your resources, annotating them adds significant value. According to OER Commons’ curation guidelines, effective annotations should identify the learning goal the resource supports, briefly describe the resource’s purpose, explain why it is useful for that goal, and include any tips or cautions to help students navigate the material. These annotations transform a random list of links into a purposeful learning pathway.

Organisation and sharing 🔗

The final curation step is organising your selected and annotated resources into a usable format. This could be a playlist, an annotated collection, a learning module, or a structured assignment. Tools like LiveBinders, Diigo (for social bookmarking), or the Groups and Folders features within OER Commons can help you organise and share your curated collections. Tagging resources with relevant descriptors also makes them easier for others to find and reuse later.

Integrating OER into teaching 🔗

Once you’ve found and curated your OER, the next step is integrating them into your actual teaching practice. The 5R framework doesn’t just define what OER are-it also defines what you can do with them. Here are the main integration approaches.

Direct adoption (reuse as-is) 🔗

The simplest integration method is using an OER exactly as it is. If you find an open textbook that aligns well with your course outcomes, you can adopt it directly. This saves significant development time. Many platforms like OpenStax and the Open Textbook Library offer complete textbooks that have been peer-reviewed and are ready for classroom use.

Adaptation and revision 🔗

Often, an OER won’t be a perfect fit. Adaptation means modifying the resource to suit your specific needs. This could involve translating it into another language, updating outdated information, rearranging chapters, removing irrelevant sections, or adding local examples and case studies. For instance, a science textbook written for a North American audience may need contextual adjustments-like local species names or measurement systems-for use in Indian classrooms.

Remixing and mashups 🔗

Remixing involves combining content from multiple OER to create something new. You might take chapters from two different open textbooks, add a video from a third source, and include your own assessment materials to build a comprehensive course pack. This is where the true power of open licensing shines-you can build a custom learning experience tailored precisely to your curriculum without starting from scratch.

However, when remixing, pay attention to license compatibility. Resources with a Share-Alike (SA) condition require that the new work be released under the same license as the original. Resources with a No-Derivatives (ND) clause cannot be remixed at all.

Asset extraction 🔗

Sometimes you don’t need an entire resource. Asset extraction means pulling out specific elements-a diagram, a data table, a video clip, a set of practice problems-and incorporating them into your existing course materials. This is a practical approach when your course is already well-structured but could benefit from stronger individual components.

Institutional policies on OER 🔗

For OER to be adopted sustainably, institutions need clear policies addressing several key areas.

Intellectual property and licensing 🔗

Institutions must establish who owns the educational materials created by their faculty. If a teacher creates a course module during work hours using institutional resources, does the institution own it, or does the teacher? Clear intellectual property policies are needed to answer this. The UNESCO 2019 Recommendation on OER encourages member states to develop policy frameworks that stimulate the creation and sharing of quality OER while remaining consistent with national copyright legislation.

Institutions should also establish guidelines for openly licensing materials developed with public funding. The principle is straightforward: if taxpayers paid for the creation of educational content, that content should be freely available to the public.

Remuneration and incentives 🔗

One persistent challenge is motivating faculty to invest time in creating and curating OER when there’s no direct financial reward. Institutional policies should address this through recognition in tenure and promotion decisions, dedicated grants for OER development, reduced teaching loads during OER creation periods, or direct financial compensation. Without such incentives, OER creation remains an unfunded, voluntary activity that competes with other professional obligations.

Quality assurance 🔗

Since anyone can create and share OER, quality control is a genuine concern. Institutions should integrate OER quality assurance into their existing mechanisms for evaluating teaching materials. This can include peer review processes, student feedback loops, and alignment checks against established curriculum standards. Piloting OER with a small group of students before full-scale adoption is another effective quality control strategy.

Indian OER initiatives: key platforms to know 🔗

India has invested significantly in building its own OER ecosystem. Here are three major national initiatives.

NROER (National Repository of Open Educational Resources) 🔗

The National Repository of Open Educational Resources (NROER) is an initiative by India’s Ministry of Education that offers a wide range of educational resources for teachers and students across school education. It provides content in multiple subjects and languages, making it accessible to India’s linguistically diverse learner population. Resources on NROER can be used, adapted, and shared freely, following OER principles.

e-PG Pathshala 🔗

e-PG Pathshala is a platform developed under the National Mission on Education through ICT (NME-ICT), executed by the University Grants Commission (UGC) and coordinated by INFLIBNET. It provides high-quality, curriculum-based, interactive e-content at the postgraduate level across disciplines including social sciences, arts, humanities, natural sciences, and languages. Research indicates that the platform hosts content across 70 subjects, with over 25,000 modules contributed by subject experts from universities and research institutions nationwide.

NPTEL (National Programme on Technology Enhanced Learning) 🔗

NPTEL is a joint initiative of the Indian Institutes of Technology (IITs) and the Indian Institute of Science (IISc), funded by the Ministry of Education. It focuses on providing high-quality educational content in engineering, science, and technology. NPTEL offers video lectures, web courses, and certification programmes, with the core content freely accessible online. It is one of the earliest and most widely used OER initiatives in India, and its courses are developed by faculty from some of the country’s most reputed technical institutions.

Other notable initiatives include SWAYAM (India’s national MOOC platform), SWAYAM Prabha (DTH-based educational television channels), National Digital Library of India, and eGyanKosh (IGNOU’s digital repository). Together, these platforms represent India’s growing commitment to making quality education accessible to all.

Challenges and the road ahead 🔗

Despite their promise, OER face several practical challenges. Awareness remains low among many educators-studies from Indian universities indicate that while some students and faculty actively use platforms like e-PG Pathshala and NPTEL, many remain unaware of the breadth of available resources. Internet connectivity, particularly in rural areas, limits access to digital OER. Language barriers persist, as a large portion of global OER are in English. And the lack of structured institutional support-both in terms of policy and incentives-slows adoption.

Yet the trajectory is clearly positive. The UNESCO OER Dynamic Coalition, established in 2020, continues to drive international collaboration on capacity building, policy development, and sustainability models. In India, government investment in platforms like SWAYAM and NPTEL keeps expanding. The critical need now is for educators at the classroom level to develop the skills to find, evaluate, and integrate these resources effectively.

What do you think? Have you explored any of the OER platforms discussed here for your own teaching? What do you see as the biggest barrier-awareness, quality, technology access, or something else entirely-to widespread OER adoption in your institution?
