Building accessible courses - Karen Holland

  1. 1. Building accessible courses Karen Holland Technical Analyst #mootieuk19 karen@lts.ie
  2. 2. “Accessibility, usability, and inclusion are closely related aspects in creating a web that works for everyone.” W3C.org Web Accessibility Initiative (WAI)
  3. 3. Accessibility means... ● Availability ● Inclusion ● Usability ● Standards ● Predictability ● Reducing negative impact of disabilities on access
  4. 4. Moodle is designed to be accessible by default to the widest possible audience.
  5. 5. Moodle Accessibility Standards Following standards: ● WCAG 2.0 ● ATAG 2.0 ● ARIA 1.0 ● US Section 508 (USA)
  6. 6. Moodle Accessibility Objectives Objectives (POUR) ● Perceivable (Knowable) ● Operable (Usable) ● Understandable ● Robust (Stable)
  7. 7. Moodle Accessibility foundations... Each Moodle page supports: (Teacher non-editable stuff) ● Page surroundings ● Navigation ● Form elements ● Skip to content links ● ARIA
  8. 8. Editable stuff... ● Assignments ● Forums ● Quizzes ● Pages ● Books ● The list goes on...
  9. 9. Atto editor features ● Accessibility checker ● Screen reader checker ● Prompts when adding media ● Prompts when adding tables ● Feature rich equation editor (Using Mathjax.org)
  10. 10. Text & Links Tips ● Colour Contrast ● Descriptive links ● Avoid “New Window” targets ● Consistent naming ● Lists (<ol> & <ul>) ● <strong>, not <b> etc
  11. 11. Headings Tips Essential for long content ● Structure ● Context ● Follow hierarchy, e.g. H3, H4, H5
  12. 12. Images Tips ● Alt descriptions ● Repeat any image text in alt ● Complex images need text description ● Meaning with color alone? ● Pixelation ● No flashing!
  13. 13. Multimedia Tips ● Deliver via accessible media player! ○ E.g. Moodle default, video.js ● Closed Captions (CC) ● Subtitles ● Text transcripts
  14. 14. Table Tips ● Tabular data only!! ○ i.e. Don’t use for layout... ● Caption ● Row & column headers ● No merged cells ● No nested tables
  15. 15. Equation Tips ● Avoid using images of equations ● Use accessible equation displays: ○ Atto equations (Mathjax) ■ Feature rich ■ Great looking ■ Fully accessible ○ Equation writers using Mathjax ○ Wiris
  16. 16. Why? Raising awareness of the obstacles faced when accessibility standards are not followed
  17. 17. Why? So that users don’t have to ask for special treatment just to get access, it’s just there
  18. 18. Thank you!
  19. 19. Questions?
