Accessibility of Online Learning


Accessibility is a general term used to describe the degree to which a product (e.g., device, service, environment) is accessible by as many people as possible. Accessibility is often used to focus on people with disabilities and their right of access to entities, often through use of assistive technology.

In regards to computer technologies, there are numerous types of impairment that impact computer use. These include:
  • Cognitive impairments and learning disabilities, such as dyslexia, ADHD or autism.
  • Visual impairment such as low-vision, complete / partial blindness, and color blindness.
  • Hearing impairment including deafness or hard of hearing.
  • Motor or dexterity impairment such as paralysis, cerebral palsy, or carpal tunnel syndrome and repetitive strain injury.nolog

Some specifics to making webpages more accessible (there are more, but these are the big hitters and a good starting point):
  • Add alternative text to all graphics (if a label is not needed, simply type a space - <img src="logo.jpg" alt=" ">
  • Use high contrasting colors (dark text on light background or light text on dark background) and stay away from using background images behind text
  • Don't use color to convey instruction (i.e. Don't say, "Click the red button". Do say, "Click the square button labelled GO")
  • Include transcripts with all audio files or video files with audio
  • Include a summary of videos with all video files
  • Use <th> tags in tables to specify the headers from the data
  • Label text entry boxes on forms so the labels are read in a screen reader
  • Ensure your pages are decipherable and readable without the use of a style sheet (style sheets can be used, but if turned off, necessary content should still be present)
  • When links to multimedia or objects requiring a software plug-in or player are present, a link to download the software plug-in or player should accompany


Accessible e-learning has 2 major components:
  1. making the interface accessible
  2. making the actual content it holds also accessible


In elearning, accessibility involves eliminating barriers to learning that many learners have found in traditional classrooms.
