Open Educational Resources: Finding OER

Finding OER

Here is a list of online resources you can use to locate free teaching materials. Some of these databases are publishers of OER meaning they facilitate the creation of open materials and provide access, while other are repositories where material from other publishers/creators is housed:

Open Education: How to do it

There are several resources that might be useful to the instructor who would like to know more about the open education movement and how to teach with open education resources.

A Guide to Understanding Open Educational Resources

This starter kit has been created to provide instructors with an introduction to the use and creation of open educational resources (OER). The text is broken into five sections: Getting Started, Copyright, Finding OER, Teaching with OER, and Creating OER. Although some chapters contain more advanced content, the starter kit is primarily intended for users who are entirely new to Open Education.

An Open Education Reader

This is a collection of readings on open education with commentary created for a graduate course at Brigham Young University and edited by David Wiley. It includes chapters on intellectual property, free software, open source, open content, open textbooks, and research in open education.

The Open Education Handbook

This handbook is a deliverable of the LinkedUp Project, and is a primer on the open education ecosystem, information about useful tools and software, references, a glossary of commonly used terms, case studies and examples, and answers to frequently asked questions. 

An Examination of the Lived Experience of Eleven Educators Who Have Implemented Open Textbooks in Their Teaching

A masters thesis by Danielle Paradis out of Royal Roads University, Victoria, BC. Of particular interest is Chapter 4, Results. It includes quotes from teachers on how they found out about OERs, their experience teaching with them, and motivations behind use.
