What do folks in education mean when they refer to ‘accessibility’? Well, in the online learning context, it really means allowing all learners, across all browsers and devices, access to all course content in an equitable manner.
Learning should not be impeded by inaccessible course content.
In this context, accessibility does not necessarily mean increasing access to course content for individuals with disabilities. Of course, this is always a concern, but the perspective should change to just ensure course content is inclusive of all learners, not just those individuals with self-reported disabilities.
Sure, you should be conscious of ADA/508 compliance issues and include transcripts to all video or audio elements, use ALT tags for your imagery, and ensure your course materials are formatted in a way that can easily be processed by assistive technologies, but you should also look at accessibility from the broader lens of usability. Is your course functional? Is it mobile responsive? Are all applications used within your course accessible to all learners?
A lot of course content developers or Subject Matter Experts (SMEs) simply don’t think of these elements when developing the content, but it’s important, prior to launch, to review your course as a whole from an accessibility and usability perspective.
Content should be chunked into smaller portions to avoid cognitive overload, it should be presented in a logical format, it should be presented using various formats (e.g. text/audio/video) alongside relevant transcripts, the course navigation should be straight forward and/or explained at the beginning of the course, formatting should be consistent, and your assessment strategies should be varied.
