OERColorado May Webinar Series

What’s the word? OER is the word! Openly-licensed Educational Resources (OER) for all educators can save schools money and allow teachers the ability to adapt free resources to their classroom context. Open Education is the movement to reduce cost and other barriers to knowledge, making education more accessible to all. 

Want to find out more about OER and Open Education? Register for the upcoming OERColorado webinar series to learn more about OER for Colorado 9am-10:30am MST. Can’t attend live? Register anyway to access the recordings and support materials.
