In order to make digital math equations that are accessible for everyone, it’s important that we design them to be accessible to screen readers, which are used by those who are blind or have impaired vision. While text is easy to interpret by screen readers, math equations can be more difficult to translate. Since accuracy is essential in math, it is important to format equations properly so that everyone has an opportunity to engage fully in the course. Fortunately, Canvas provides built-in tools that make creating accessible math content simple. Below are strategies and resources to help you make the most of these tools.
Generating equations on Canvas
Canvas includes a built-in equation editor that allows users to insert mathematical symbols and expressions directly into their content.
Using LaTeX
The LaTeX math notation language can create mathematical expressions with high quality formatting, which can provide the user with more precise control. This code can be copied into the Canvas equation editor using the “Directly Edit LaTeX” setting. This will automatically convert the expression into MathML, which allows screen readers to interpret the expression correctly and eliminates the need for alt text.
Using AI
AI tools can quickly convert handwritten math or typed equations into LaTeX code, which can save time in improving accessibility. For example – uploading a photo of a handwritten quadratic formula, and prompting for the LaTeX code the AI would return the following:
x = \frac{-b \pm \sqrt{b^2 – 4ac}}{2a}
This can then be directly copied into the Canvas equation editor for instant results.
