Dr. Ally – a diagnosis for digital accessibility
You’ve just uploaded a PDF to Moodle. It’s visual, colourful and you’ve invested a lot of time creating it. But what’s this? A bright red dial has appeared next to the file!
This is Blackboard Ally letting you know that there are accessibility issues with your file. As a college, LCC has a reasonably high accessibility score with an 80% average; however, there are still nearly 1,800 documents on Moodle with accessibility flaws.
And so, on Thursday, March 17th, Lee Leewis dressed in a white lab coat and hosted a drop-in session as Dr. Ally, helping to diagnose and cure some of the most common accessibility issues at LCC including missing alt text, poor colour contrast, missing headings, and reading order.
|Accessibility problems||Why is it important?|
|Images missing Alt Text||Text based, alternative descriptions for your images help students understand the image’s purpose, especially students using screen-readers.|
|Poor colour contrast||There should be a clear colour contrast when text is overlaid on top of an image, otherwise it’s difficult to read.|
|Missing document headings||Heading styles like H1, H2, P, or Title help organise information and create a clear reading structure, particularly for screen-readers and assistive technology.|
|Missing table headings||Screen readers and other assistive technologies rely on table headings to know what each column or row represents.|
|Incorrect reading order||With PowerPoint or Keynote in particular, the order in which you add content often determines the order in which it is read by screen readers and other assistive tools. This can be particularly problematic the more material you have on your slides.|
Lee also handed out prescriptions for quick accessibility fixes in course documents, PDFs, and PowerPoints.
In the next instalment of Dr. Ally, Lee will present a virtual escape room using corrupted documents, PDFs, and PowerPoints as keys to the next room.
Tuesday, May 10th from 11.00 – 12.00 on Collaborate Ultra
