For online instruction, following basic digital accessibility best practices will help ensure content is more accessible to students, including the following from Universal Design Cheatsheet from MSU Web & Digital Communications:
"There are no absolute ideals for accessibility that will provide access to all people. However, by following these guidelines, [users] are less likely to be needlessly overlooked." (Gilson & Kitchin, 2007)
The following is an abbreviated list from the Full Image Description Guidelines from the Diagram Center:
While a word cloud itself is usually not accessible because it’s often inserted as an image, an alt-text description listing the words in order of importance can be used as an alternative.
Provide a text alternative that conveys the top, most common words in the word cloud.
If you see two fields for both a Title and Description when you are adding alt text, use the Description field.
Why? Microsoft's intention: "The screen reader first reads the title. The person can then decide whether to hear a longer description." If there is no title, it will just read the description.
