Just wanted to share an answer I provided to the question:

Can you name an option for accessible learning management tools?

While I know there are many providers, I could think of the following three:

ATutor; AContent; and ATutorSpaces (Open Source): http://www.atutor.ca

Anthology (formerly Blackboard): https://www.anthology.com/trust-center/accessibility

Digial Chalk: https://www.digitalchalk.com

• GLAAD at Digital Chalk; and

• 3Play Media Integration for Digital Chalk
