Hi Brian, thanks.
I don’t think the fully online course can be ‘accessible to all’. But I do think we can do our best to make it accessible to many/most.
If we develop learning resources with an awareness of functionality with screen readers, closed captions, adjustable font styles sizes, colours. software and apps which work across platforms and devices. Offering relevant language options in multilingual institutions.
With robust process for learners to inform us of their specific support needs and processes in place to provide assessments which are not detrimental to the student who has known support needs.
