Before using an open educational resource, it is important to do some planning. Consider:
There are a number of open educational resources available to use and adapt to fit. Like any learning resource, it is important to ensure it is of sound quality. Is the OER relevant and applicable to the subject being taught? Is the OER pitched at the right level? Is the content up-to-date? Who developed the content?
However you decide to use an open educational resource, it's important to take note of the Creative Commons license attached to the resource. Creative Commons provides a good resource - 'Best Practices for Attribution'.
Ensure your new or adapted open educational resource is accessible for its readers. Does the OER follow best practice accessibility guidelines? Is the OER inclusive for students from diverse backgrounds? If the OER is not accessible, reach out to the Open Research Team or Accessibility Services for guidance.
