Accessibility is the design of digital course materials, platforms, and activities so that students with disabilities can perceive, understand, navigate, and interact with them.
How it works
Instructional designers and faculty apply accessibility checks when building course shells in the learning management system. Videos are captioned, documents are tagged for screen readers, and third-party tools are reviewed for conformance. Students request additional accommodations through the institution’s disability services office; those accommodations are implemented in the online environment.
Example: an online lecture video is uploaded with accurate closed captions. The accompanying slide deck is exported as an accessible PDF. A student who uses a screen reader can navigate the learning management system and complete all required activities without relying on visual information alone.
How it differs
Usability refers to ease of use for the general population. Accommodation is an individualized adjustment provided after a student request. Regular and substantive interaction concerns academic engagement; accessibility concerns whether every student can reach that engagement.
Common errors
Assuming an automated accessibility checker guarantees full compliance. Uploading uncaptioned video because “most students can hear.” Treating accessibility as optional for courses that enroll no currently identified students with disabilities.
