What is OER?
The Hewelett Foundation defines Open Educational Resources as: “teaching, learning and research resources that reside in the public domain or have been released under an intellectual property license that permits free use and repurposing by others.”

OER may include textbooks, videos, tests and assessments, software, course content and even full courses. These materials are shared under Creative Commons licensing which allows the content to be freely used, copied, and remixable. The goal is have content that is free of barriers to access and sharing for educational use.

Why do I care about OER?
Textbooks are expensive. Using OER instead of publisher content that students must purchase makes education more affordable. OER gives you freedom to decide what to teach when in your course. Simply plan your course and then look for the resources to support your content and assignments rather than following the textbook structure. OER are just as good, and sometimes better, than publisher content.

Why isn’t everyone using OER?
In a 2014 survey, most faculty were unaware of OER. Those who were aware were deterred by the lack of search tools. Locating appropriate resources took too much time and energy. Fortunately, the lack of search tools is changing. Over the last decade several OER repositories and search tools have appeared to curate all this incredibly useful content.

Where can I find OER?
These searchable sites are great places to start looking for content you can use in your classes.
