Always provide multiple means of representation. Add meaningful alternative (alt) text to all images, diagrams and tables.
Why this matters...
Provide textual alternatives
If you are using specialist communication techniques like images, tables or multimedia, always ensure the same information is provided in an alternative textual format.
Be specific, and succinct
If you are writing a textual alternatives, focus on a brief description that provides an equivalent meaning for users unable to access the image or media source.
Multiple representation
If you are explaining a challenging concept or are providing essential information, provide more than one way to help student understand it.
Learns will always have different ways in which they are able to perceive and comprehend information. Instead of focusing on one way to communicate, you should always ensure you use multiple means of representation. This means providing textual alternatives for any non-text content. It also includes the use of multiple approaches, explanations or examples to explain a concept, allowing learners multiple opportunities to grasp it.
