Creating Accessible Course Content with Canvas LMS
Last modified 11/16/2023
Canvas is user-friendly and intuative providing educators and learners with a range of powerful tools and features to make teaching and learning more engaging, interactive, and effective.
Accessibility is an essential aspect of Canvas, as it ensures all learners, regardless of their abilities or disabilities, have equal access to educational content and resources.
Tips for Canvas
To help you make your Canvas courses more accessible, here are some helpful hints. By following these guidelines, you can create a more inclusive and accessible learning environment in your Canvas courses, and ensure everyone has an equal opportunity to succeed.
Use Descriptive Hyperlinks
Add descriptive text to your hyperlinks to convey the purpose of the link. Avoid using long complicated URLs or generic text such as "click here."
Add Alt Text to Images
Ensure all images have alternative text (alt text) that describes the content or function of the image.
Structure Headings and Subheadings
Use headings and subheadings to create a logical nested order for your content and improve navigation for screen reader users.
Provide Transcripts or Captions for Audio and Video Content
Transcripts and captions for audio and videos help ensure the content is accessible to a wider audience, including those with disabilities.
Use High Contrasting Colors
Using high-contrast colors between text and background improves readability for learners with visual impairments.
Assign Table Header Cells
Format your tables by assigning row and column header cells appropriate to the table's content.
Show Table Caption
Adding a caption to a table helps provide information students can use to find, navigate to and understand the its purpose. Provide a title or short summary of the table's purpose.
Use Simple, Clear Language
Keep your language simple and clear so it is easy to read and understand. When possible, avoid using jargon or complex terminology.
Check for Keyboard Access
Make sure all interactive elements, such as forms and quizzes, are keyboard accessible, and can be navigated without a mouse. This includes 3rd party applications and Learning Tool Integrations (LTI).
Canvas' Accessibility Checker
Canvas' Accessibility Checker is available in Canvas’ Rich Content Editor. This tool allows you to run quick accessibility checks on your content within the Rich Content Editor. Remember, the accessibility checker does not check for all issues or any content you link to from other sources.
Here is a list of components commonly verified by the Canvas Accessibility Checker:
- Adjacent links: Adjacent links with the same URL should be a single link. This rule verifies link errors where the link text may include spaces and break the link into multiple links.
- Heading paragraphs: Headings should not contain more than 120 characters.
- Image alt text: Images should include an alt attribute describing the image content.
- Image alt filename: Image filenames should not be used as the alt attribute describing the image content. Currently, files uploaded directly to Canvas create a redirect that does not properly verify image filenames.
- Image alt length: Alt attribute text is recommended to contain fewer than 120 characters.
- Large text contrast: Text larger than 18pt (or bold 14pt) should display a minimum contrast ratio of 3:1.
- Lists: Lists should be formatted as lists.
- Sequential headings: Heading levels should not be skipped (e.g. H2 to H4). However, the tool does not check if the first header starts with H2 or whether the headings are sequential with the rest of the content in the page. Tables do not begin with H1, which is designated for the page title.
- Small text contrast: Text smaller than 18pt (or bold 14pt) should display a minimum contrast ratio of 4.5:1.
- Table captions: Tables should include a caption describing the contents of the table.
- Table header scope: Table headers should specify scope and the appropriate structure.
- Table header: Tables should include at least one header.
