Blog Post created by Christopher Phillips on Sep 21, 2017

The following is a blog post version of a presentation I gave at Instructurcon 2017 titled, “Mission Possible: Accessible Course Materials." Video available below, additional resources available at the bottom.

This video has been captioned. You can also download the transcript and follow the discussion on captioning conference videos here.  

 

Introduction

I am confident that no one has all of this accessibility puzzle figured out, but if you take some time to get to know people in the Canvas Accessibility Community there are individuals with a lot of pieces of the puzzle.

At Utah State University (USU) we have been working on providing more inclusive online course experiences and ensure we are meeting the requirements of a recently approved campus Electronic and Information Technology Accessibility Policy. Canvas does great work towards making the core functionality of Canvas accessibility. Here we are going to focus more on accessible content, the stuff added by an instructor or course designer.

If you are brand new to accessibility or a long-time disability advocate, right now is an incredible time to be a part of this discussion on inclusive educational experiences. Before we get into the what and how of accessibility let’s spend just a moment discussing the why of accessibility.

Why Accessibility?

There are increasingly legal reasons to care about accessibility. However, there is so much more to accessibility beyond consideration of any legal risk. Great accessibility means greater usability and more usable course materials are more learnable for all students. Making sure your content is accessible provides a more inclusive experience for students with disabilities, second language learners and other nontraditional learners. Everyone benefits from more accessible content.

The discussion used to be around why you would take the time and effort to make your content accessible. Increasingly it feels like that question is changing towhy on earth you wouldn’t make your online course materials accessible. Especially with the availability of some of the incredible tools we willlook at below.

If you are new to accessibility and start to feel overwhelmed, take a deep breath and remember that accessibility is a journey. It is much more important to get started than to nail down your destination. There is always more to do when it comes to accessibility, but there is also always something you can do today to make your content more accessible.

HTML Content vs File Content

As we talk about course content I want to make sure we are on the same page. There is an important distinction with how these tools treat native HTML content and file content.

  1. HTML Content. When I talk about HTML content I am referring to content that is entered through the WYSIWYG editor that shows up natively in the browser.
  2. File Content. When I talk about file content I am referring to files uploaded to a course such as PDF, Word,or PowerPoint.
  3. Media. Media such as images and video can be present in both HTML and File content.

It is important that we consider both HTML content and File content when looking at accessibility.At Utah State we recently did a quick audit on the type of content in our courses for one semester and found that we had:

  • 101,160 pages of HTML content.
  • 171,433 uploaded files.

If you ignore either type of content a significant portions of your course experiences may not be accessible.

Overview of the Tools

Now let’s look at some tools. All of these tools are different and the goal is not to determine which tool is best but rather to share what each does to help you determine how they might support your accessibility goals.

Design Tools from CIDI Labs

Design Tools (also known as Kennethware) is a commercial product that provides a suite of tools to help with course development. It includes a set of tools to help course developers make their HTML content is accessible at a page level as it is developed.

UDOIT from the University of Central Florida

The Universal Design Online Content Inspection Tool checks the accessibility of your HTML content across a entire course. UDOIT is open source, you can download it today for free and all you have to pay for is the hosting.

Ally from Blackboard

Ally started out as a tool developed for Canvas but was purchased by Blackboard and how supports multiple learning management systems. Ally is a commercial product that looks at the accessibility of course files on a single page, across an entire course or across all of your courses.
