How do I make my course resources accessible?
PDF and eBook Accessibility
PDFs can be highly accessible, with appropriate organization and document tagging. Two of the most important things to focus on when selecting PDFs for a course are quality and OCR compatibility. A high-quality PDF is clear and easy to read, ideally with alt-text for images and headings for easy navigation. A low-quality PDF might be a scan of a book chapter with hand-written notes in the margins. OCR–Optical Character Recognition–means that the text in the PDF has been scanned and configured to read as text, rather than as an image. You can easily tell if a PDF is OCR compatible if individual words can be highlighted or searched.
When selecting an ebook, check the format (or formats) that it is available in, as some are more accessible than others. For example, epub, the most common ebook format, is now aligned with the DAISY standards, which set forth publishing guidelines for making ebooks accessible. HTML formatted ebooks also tend to be more accessible to screen readers and other assistive technology. The best thing that can be done with ebook selection, though, is to identify and share the ebooks early, so that students who may need alternatives can get them before class begins.
Is this a book that is easy to get? Does it [come from] a publisher who’s generally easy to get in alternate formats? … And we ultimately end up having to cut up the student’s book and scan it. And do we actually get to check it and make sure the OCR didn’t make any mistakes? No. We just don’t have the staff. And that’s that much harder to get to a distance learning student than it is a student who can swing by [our] office and pick it up.
When choosing textbooks, it’s worth investigating if alternate versions are available. Can a large-text version be purchased? Or a Braille version? Regardless of availability, it is again extremely helpful to provide the list of textbooks as early in the process as possible so students can locate alternatives.
Another consideration in textbook accessibility is cost. The often-high cost of textbooks affects all students, but it can hit students with disabilities disproportionately hard. People with disabilities are more likely to have lower incomes than their nondisabled peers, as well as higher medical costs (APA Disability and Socioeconomic Status Fact Sheet). This could make obtaining a textbook, especially an alternative edition, a costly challenge for a student with disabilities. When picking a textbook, consider the price tag. Is the latest edition necessary? How much of the textbook will students read–could the chapters be placed on Course Reserves for free? These alternative options will make your course more accessible to all students.
