22. What About Accessibility?
Addressing the needs of ALL Students
Discover Learning Resources based on disability
needs and learner preferences
●
Compatible with AT, WCAG guidelines
●
Leverage MathML, tactile graphics and image
descriptions
Have closed-captioned video
●

23. Leveraging Access For All
●
Gates Foundation funded Benetech to develop a
Schema.org proposal for Accessibility Metadata that
would be complementary to LRMI
●
Benetech assembled a broad Working Group of
experts
– AEP (LRMI), APH, Dublin Core, EDItEUR (ONIX), Gooru
Learning, IMS Global, IDRC, NCAM, SRI (Learning Registry)
●
Proposal submitted to Schema.org in April 2013
– Influenced heavily by IMS Global Access for All
– Released under a Creative Commons BY-SA License
