Unlike libraries, where content is evaluated and curated from a set of items identified through publishers, open educational resources can be found everywhere and anywhere and have no set form of evaluation before they are made available to the public. This lack of evaluation makes developing a search plan very important.

Before beginning your search for an open education resource, you need to have a clear plan. This will help you make decisions on what tools to use for searching, the kind of resource you select, and the subject coverage. The following checklist will help you plan your search strategy as well as help you identify whether a resource will suit your needs:

Audience

• Who will be using the resources?
• Is the resource at an appropriate education level for your audience?

Subject Coverage & Relevance

• Does the information directly address one or more of the class objectives?
• Is there any area within the larger subject that should be excluded?

Material Type

• What kind of media does the collection contain (e.g. videos, podcasts, etc.?)
• What media types are excluded from the collection?

Pedagogical

• Does the resource encourage active learning and class participation?
• Does the information directly address one or more of the class objectives?

Accuracy & Production Quality

• Is the information accurate?
• Are there major content errors or omissions?
• Is the resource available in alternative formats (e.g. .doc)?
• Are the layout and interface easy to navigate?
• Do the design features enhance or inhibit learning?
• For image, audio, or video resources, is the picture/sound quality high?

Interactivity

• Does the resource encourage active learning and class participation?
• Are there opportunities for students to test their understanding of the material (e.g. a video with embedded questions)?

Licensing

• Does the license allow for educational reuse of materials?
• Does the license allow modifications or adaptations of the material?

Answering these questions will help you during your search by identifying different filters you can use to narrow your search results and evaluate the resources once the search results come in.

OERs are usually found in repositories that specifically collect these resources together. There are a large number of OER repositories, and new ones are being created every day as people collect and organize resources specific to their needs.

The best place to start looking for resources is in a few of the largest and more comprehensive repositories.

Major Repositories

Mason OER Metafinder (MOM)

The Mason OER Metafinder searches across 21 different sources of open educational materials. It searches well-known OER repositories like OpenStax, OER Commons, MERLOT but also sites like HathiTrust, DPLA, Internet Archive and NYPL Digital Collections where valuable but often overlooked open educational materials may be found.

MERLOT

The MERLOT collection consists of tens of thousands of discipline-specific learning materials, learning exercises, and Content Builder webpages, together with associated comments, and bookmark collections. These materials have been contributed by the MERLOT member community who have either authored the materials or who have shared existing open education materials. Materials in MERLOT are reviewed for suitability for retention in the collection. Many undergo the more extensive peer review process for which MERLOT is known. MERLOT has also added a “Smart Search” function which searches for OER at other libraries/repositories, and which can also search the web using a proprietary MERLOT user profile design to find the newest and most popular learning materials available.

OASIS

Openly Available Sources Integrated Search (OASIS) is a search tool that aims to make the discovery of open content easier. OASIS currently searches open content from a large number of sources.  At the outset, users can start a search if they know what they’re looking for, or they can view the variety of OER source types available to them—textbooks, courses, interactive simulations, audiobooks, and learning objects are just a few of the tools one can look for.

OER Commons

OER Commons offers a comprehensive infrastructure for curriculum experts and instructors at all levels to identify high-quality OER and collaborate around their adaptation, evaluation, and use to address the needs of teachers and learners.

Searching with Google

Another great place to start your search is through Google. Google’s Advanced search offers the ability to filter your search results by license.

Google offers 5 usage rights options that correspond to different Creative Commons conditions.

• Not filtered by license – This tells Google to ignore this filter and include copyright items in the search.
• Free to use or share – This includes items that have NC and ND licenses.
• Free to use or share, even commercially – This excludes items that have NC licenses.
• Free to use share or modify – This includes items that have NC licenses but excludes ND licenses.
• Free to use, share or modify, even commercially – This excludes items that have NC and ND licenses.

You can also filter image searches by license, which is found under “Tools”

If you are looking for a specific type of OER, here are some good places to look.
