If you tell students to “click the green button,” those who are colorblind may not know which one you mean. This can cause confusion and slow them down. 

Use both color and text in your directions—for example, “Click the green ‘Submit’ button.” 

Adding text labels along with color ensures every student can follow your instructions clearly. 

Images without alternative text (alt text) can be invisible to students who use screen readers. Without it, they miss out on important context in assignments, announcements, or presentations. 

Add a short alt text description that explains the purpose of the image (e.g., “Map of Tennessee showing TCAT locations”). 

Taking a few seconds to add alt text ensures all your students have equal access to the information you want to share.
