Inclusive learning is about creating a learning environment where every student feels valued and has equal ability to learn.
Alt-text is an alternative method for supplying information about images to users who are visually impaired. Since screen readers are unable to describe images, alt-text is used to help screen readers describe the image. But alt-text can be beneficial to many more groups, as it also offers an alternative for image files that cannot be displayed due to poor internet connections or other errors. It can also provide better image context for search engine crawlers, helping them index the image properly.
Alt-text is essential in making the learning content more accessible for the visually impaired and is considered one of the simplest methods for achieving inclusive learning.
But having good alt-text on graphics, charts, graphs and diagrams is about more than just having a description. It’s about having the right context, message and learning experience the student will have through engaging with the image representation. It encompasses the true meaning of the learning content.
