In collaboration with our technical partner we have made our Moodle fully digitally accessible, with translation in sign language. Our freely accessible e-learning is in Dutch and French, but not in English (sorry). I hope it inspires developers to make this version freely accessible to all Moodle-users. You'll find it on www.ediv.be. Please create an account and go to the 3rd module on Handicap. Here are some screenshots:
The handicap module offers three chapters (intro lesson, quiz and lesson). The icon with the two blue hands offers the translation in sign language.
This drag and drop exercice offers an accessible version for blind users by clicking on the button: version without drag and drop. The exercise then becomes an exercice with dropdown menus.
