You can evaluated OER in a similar manner as you do regular textbooks and course content. However there may be additional things you want to consider.
- What is the intended audience/level for the work?
- Does this content fully cover what you would like your students to learn? If not, would you like to revise it yourself? Do you want to combine it with other existing OER?
- What do the license terms allow you to do with the work? Do they meet your needs?
- What are the credentials of the creator or repository?
- Has the work gone through any peer review process?
- When was the work last revised or updated?
- What file format is it in? Will your students be able to easily access it? If you wish to modify it, how easy will it be for you to do so?
- Is it accessible to all students?
- Is the content free of cultural bias and stereotypes?
