My understanding is that the built-in math editor is not accessible and is not compatible with screenreaders. A proposed solution is to enable MathJax.

MathJax is a display engine for mathematics that works in all browsers, is compatible with screenreaders, and provides zoom. Enabling MathJax would allow Canvas to automatically recognize mathematical commands/formulas and display them. Other (potentially) attractive aspects of MathJax include the ability to click/toggle through a sequence of text (e.g. hints/directions for exercise), add mouse over text (e.g. remind students of important definition), and shorthand for typesetting chemical equations.

Perhaps this feature request would get more attention and votes if the title were changed to something like "Make the Math Editor Accessible".

Right now, my understanding is that the built-in math editor is not accessible. The alt text generated is in LaTeX, which is not compatible with screen readers. Screen readers work with MathML or of course English (preferably, MathSpeak natural language descriptions). See: Accessibility at Penn State | Equations: MathML, Images and LaTeX

Someone elsewhere claimed that the Math Editor puts both LaTex and mathML in the alt text, but we tested it out with standard screen readers and none worked with it.

So the workaround now is, after adding an equation using the math editor in Canvas, you have to manually edit the alternative text to have an English description. The issue here is what if your English description is inaccurate.

Conversely, MathType/WIRIS (which costs money after a free period), automatically generates an English-language description. 3rd party math homework tools like MyOpenMath and Ximera use MathJax and have nice accessibility features and MathML support.

So if the built-in math editor could support MathML or just use MathJax, it would help prevent inaccurate or inaccessible math equations and science formulas.
