You might assume, "If I have no students with documented disabilities, then I am off the hook here." Not the case! There are good reasons to implement practices to ensure accessibility, usability, and quality visual design that are more than accommodations for disabilities.
Overall, it is good practice to provide multiple ways of viewing, consuming, and accessing content in your course.
Disability accommodations are specific, individualized changes to instructional materials, settings, and approaches that are required for students with documented disabilities. A common type of accommodation for learning disabilities is, for example, extended time for completing assignments and/or taking exams.
The law that governs accommodations is the Americans with Disabilities Act (ADA), specifically Sections 508 and 504. Section 508 mandates that all electronic and information technology receiving federal funds must be made accessible for those with disabilities or learning differences. Section 504 requires accommodations for those who have learning differences in higher education must receive any type of required accommodation to make learning equal to peers.
Accessibility is a more general term that applies to many people and not only those with documented disabilities. In the context of designing courses using Canvas, accessibility means making it possible for all students, regardless of physical or developmental impairment, to use all course materials and tools. Designing for accessibility from the beginning will save you time and stress when a disability accommodation is necessary. A course is accessible to the degree that every student can get to, perceive, and navigate course content and assignments; submit assignments; and successfully use all course tools. Accessible design is often included under the larger umbrella of Universal Design for Learning, because it considers all possible users and is inclusive to everyone.
Accessibility of digital content is important because:
There are four major categories of disability or differences requiring different practices to ensure accessibility to digital content in your course. These disabilities or differences can be permanent or temporary, and may result from genetics, disease, injury, or age-related changes.
Visual disabilities or differences include blindness, low vision, and color blindness. Individuals with visual differences may:
Hearing disabilities or differences include partial and complete deafness. Individuals with hearing loss may not be able to hear the audio of a podcast, a voice-over in a PowerPoint, or the speech, music, or sound effects in a video. Students with hearing differences may:
Cognitive disabilities include learning disabilities or differences and other disorders that make individuals distracted or unable to focus on, process, or remember information. Individuals with cognitive disabilities may:
Motor disabilities include paralysis and limited fine or gross motor control. Individuals with motor disabilities may:
If you don't already include a statement about your commitment to accessibility and support of students needing accommodations in your syllabus, consider adding one. Here is a model:
"I strive to achieve accessibility for all people in my courses by providing material that works for students with disabilities, whether mental health, learning, chronic health, physical, hearing, vision, neurological, etc. I also encourage students to document their disabilities when doing so means that you may receive accommodations to support you in your learning.
