Once you've developed a basic understanding of the OER essentials, there are many ways to engage with OER for your courses, some more time and labor-intensive than others.
You can Adopt an existing OER as is into your course, Adapt an OER by making changes to parts of it, or Create an entirely new OER. Here are some recommendations for Starting Small:
Make a list on your website or blog.
Send it to a discipline's mailing list.
Post it on social media like Academia.edu or LinkedIn.
Share it with your library subject specialists.
Whether creating something new or adapting an existing OER, there are several important considerations to keep in mind, especially with regards to format.
To re-use the work of another, the format is important. It's difficult to make edits to a PDF file, and some older file extensions (e.g. .wps) can be difficult to use on modern computers.
Consider offering your text-based teaching materials in an accessible and editable format like Rich Text File (.rtf) or even a plain text file that can be read by a number of different software programs. An HTML file is a good option too.
Making a video for your class? Consider the format and the available players carefully. The .mp4 extension is often recommended for OER because of the many players that read it and its easy reuse for others.
