What are OER?

The William and Flora Hewlett Foundation defines 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.”

OER consist of educational materials such as open access textbooks, websites, documents, modules, and courses that can be legally and freely used. All OER are openly licensed, which means you can download and adapt these materials. Open licensing also allows you to create your own OER and then share these materials with others for them to reuse, revise, and redistribute.

Watch this helpful video from Iowa State University for more information about OER and why they are important.

What are AER?

You can think about resources like library ebooks and articles as AER, or affordable educational resources. While they are not openly licensed and are not considered OER, they function in the same way for your students and present no additional cost to your students. They are easily accessed and are high-quality.

Why should I use OER and AER?

Affordability

OER and AER are almost always available for free or low-cost (<$25), which means that students don’t need to worry about taking out extra loans or paying for textbooks on top of tuition and other bills. When students don’t have to worry about textbook costs, they can more easily focus on learning.

Access

OER are available to students on day one of class and open licensing makes it possible to download ahead of time and save for easy access. Because AER include resources like library ebooks and articles, students already have access to them through the library.

Innovation and Flexibility

Open licensing gives instructors the ability to incorporate open pedagogy into their classroom. Here are just a few examples of how you can use OER to engage in open pedagogy from Robin DeRosa and Rajiv Jhangiani. Instructors also have the freedom to edit and combine OER to craft a resource that meets their class’s specific needs.

Integration in Canvas

OER and AER are easily integrated into Canvas courses. Students can access these course materials quickly and in one place, whenever and wherever they need them.

What if my students prefer print textbooks?

Many OER offer the option to print pages as PDFs, so students can print the pages they need if they so choose. Some OER are also offered in physical format, such as OpenStax textbooks.

What am I allowed to do with openly licensed resources?

You can learn more about different types of open licenses and their permissions with them here and in the “What can I do with OER?” section of this guide below. Additionally, this page explains which license you should choose if you create your own OER.

  2. Revise: edit, adapt, and modify your copy of the resource
  3. Remix: combine your original or revised copy of the resource with other existing material to create something new
  4. Reuse: use your original, revised, or remixed copy of the resource publicly
  5. Redistribute: share copies of your original, revised, or remixed copy of the resource with others

Creative Commons Licenses

Here is brief explanation of what Creative Commons Licenses are and how they work:

“The Creative Commons copyright licenses and tools forge a balance inside the traditional ‘all rights reserved’ setting that copyright law creates. Our tools give everyone from individual creators to large companies and institutions a simple, standardized way to grant copyright permissions to their creative work. The combination of our tools and our users is a vast and growing digital commons, a pool of content that can be copied, distributed, edited, remixed, and built upon, all within the boundaries of copyright law.”

Creative Commons license components

  • Attribution (BY): Proper attribution must be given to the original creator of the work. This includes a link to the original work, information about the author, and information about the original work’s license.
  • Share-Alike (SA): Iterations of the original work must be made available under the same license terms.
  • Non-Commercial (NC): The work cannot be sold at a profit or used for commercial means such as for-profit advertising. Copies of the work can be purchased in print and given away or sold at cost.
  • No Derivatives (ND): The work cannot be altered or “remixed.” Only identical copies of the work can be redistributed without additional permission from the creator.

These four components can be combined to create a total of six different Creative Commons licenses, varying in openness and what they allow users to do.

Creating and editing OER

Below are helpful resources for those interested in creating their own OER or modifying existing resources to suit their needs. Contact Karlyn Schumacher ([email protected]) with questions about this process and to request assistance.

OER and AER at Ripon College

OER and AER Impact at Ripon College, Spring 2021

Estimated maximum student savings $23,605.54
Total unique instructors using OER & AER 12
Total unique courses using OER & AER 17
Total students served 359

See the full Ripon College OER & AER Impact Tracking sheet for more details.

Lane Library began tracking the use of OER and AER at Ripon College in the spring of 2021 to estimate student savings from switching to OER and AER. There are several methods for estimating savings, and the library used recommendations and templates from Open Oregon and the University of Alaska Southeast in crafting its approach.
