If you need to request accommodations on the basis of a disability for library content, please visit the Accessibility Resources and Services website.
In order for learners to engage with your content effectively, it needs to be well designed.
Do away with ideas of learners being lazy, unable to deal with challenging material, or unable to learn a new technology. Humans have natural limitations to their sensory and language processing, and if we push those limits, students will have little cognitive power left over for learning.
There are relatively rare individuals who can accommodate more sensory or information overload. Those gifts, while useful and impressive, are separate from ability and intelligence. We shouldn't screen out perfectly capable students just because they lack a neurological quirk that allows them to assimilate poorly presented content.
The principles of Universal Design for Learning will assist you in creating Open Educational Resources that work for all kinds of learners. In particular:
No educational resource is really Open if it's not usable by people with disabilities. This is the law - the Americans with Disabilities Act and sections of the Rehabilitation Act require it.
Use this Universal Design for Online Learning tutorial from the University of Northern Colorado as preparation for creating Open Educational Resources. You will notice that many of the videos I am including only have YouTube's terrible automatic captions. These have gotten much better in the past couple of years, but they are still not ideal. Only the owner of a YouTube video can add captions - that's why, even if there's a Creative Commons license, it's not really an Open Educational Resource unless you can get the source file in an editable format!
