Online learning can expand access, but only when the platform, content, teaching practice and support model are designed for different ways of perceiving and interacting.
Choose an accessible learning platform
Core tasks—finding a course, reading content, submitting work, taking assessments and participating in discussions—must be possible with a keyboard and assistive technology. Procurement should require current accessibility evidence and include user testing.
Create structured course content
Use real headings, lists, tables with headers and descriptive link text. Provide text alternatives for meaningful images and extended descriptions for complex diagrams. Do not rely on color, position or visual formatting alone.
Plan accessible media
Videos need accurate captions and, when important visual information is not conveyed in the audio, audio description or an equivalent text description. Audio content needs transcripts. Media players must be keyboard accessible.
Make STEM information perceivable
Mathematics, charts and scientific diagrams require more than a screenshot. Institutions should use accessible mathematical notation, structured data, tactile graphics where appropriate and advance coordination with the student.
Design fair assessments
Assessment tools must work with assistive technology, and time limits should account for approved accommodations. Provide accessible practice environments before a high-stakes assessment so students are not testing the platform and their knowledge at the same time.
Communicate early
Reading lists, assignments and presentation materials should be available early enough for conversion or adaptation. Instructors should explain visual references during live teaching and identify speakers in discussions.
Support should be coordinated
Accessibility should not depend on one disability-services employee repairing every course. Faculty, instructional designers, IT, procurement, library services and disability support need shared responsibilities and escalation routes.
