Accessibility benefits all learners
In many cases, improving the accessibility of course content benefits all students, including those without a disability. Accessibility is often closely connected to the quality and usability of the course materials.
Example 1:
Having a proper digital copy of a document instead of a scan makes the document more usable for all students. It might make the document easier to read, especially for low-quality scans, and it also allows students to search through the document and find specific content, copy and paste sections of the document, and so on.
Example 2:
The Semantic HTML alternative format is fully responsive and mobile-friendly and makes it easier for all students to consume to content on their mobile device. The ePub alternative format makes it easy to change the visual display of a document and allows for annotations and highlighting to be added. The audio alternative format can be used during a commute, on a run, etc.
Example 3:
Having a video with captioning or a transcript will make the video more usable for all students. It allows the student to search through the video and find specific parts, the video can still be watched in high-noise environment (for example, commuting), and so on.
Example 4:
Having an image with a quality description can make the image more usable for all students. It can help clarify the content of the image and how it connects to the surrounding context, it makes the image searchable, and so on.
Example 5:
Providing a good heading structure for a long document makes the document more usable for all students. It provides additional structure, which makes it easier to work through and process the content. It also allows for a Table of Contents to be generated, which can improve the navigability of the document.
