Symbols have been used in special schools for decades. They’ve been a fantastic aid in language development and communication. But from my experience, teachers of children with special needs have a blind spot about their use that limits their effect.
How do I know? Well I was a headteacher of a school for children and young adults with severe, complex and profound learning difficulties for a decade. And I’ve tested out my theory successfully on special educators in countless courses I’ve led.
So, what’s the problem? Take a look at the image below, which is how symbols are pretty universally used: as a word processor.
Now look at an edited version, with the keywords arranged in map fashion — a format you almost never see in use. Which do you think is clearer and easier to communicate? Yes, this one by far.

Why is that? Because the traditional way of communicating symbols is still linear. And, as such, relies on syntax, one of man’s most complex and abstract set of rules. If students in a special school had mastery of syntax, they wouldn’t be there in the first place! So an alternative to syntax is needed.
Which, strangely enough, is exactly what Tina Detheridge the originator of the ubiquitous Writing with Symbols and author of Literacy Through Symbols believes too. In 2006 we co–wrote an article on this subject, Making Ideas Come Alive, for the Special Children magazine. Go to modellearning.com to download the full article.
