Because much of the content in math and science fields is presented via complex visuals (e.g. equations, charts, diagrams and maps), making the content accessible on a screen reader may seem daunting, if not impossible.
However, these steps below can help instructors and other present content which is accessible and still retains the original visual characteristics.
- Ensure that all general course guidelines are met.
- Ensure that equations are either in MathML or images with an ALT tag or in MathML.
- Ensure that technical symbols are supported on a student’s screen reader.
- Ensure that all complex images include a text-based long description.
- Ensure that all charts can be interpreted without color and include a properly tagged data table.
- Ensure that data tables include headers in the top row and a caption or summary. Simple tables are strongly recommended.
- Ensure that diagrams or charts supplement color coding.
