Aided Language Stimulation
What is Aided Language Stimulation?
Aided language stimulation (ALS) is a communication strategy, where a communication partner teaches symbol meaning and models language by combining his or her own verbal input with selection of vocabulary on the Augmentative and Alternative Communication (AAC) system. This is done by simultaneously selecting vocabulary on the AAC system and speaking. Comprehension and communication on the AAC system are promoted through modeled use of visual icons/graphic symbol and providing the corresponding verbal label. Learners are prompted to use symbols to communicate within context of motivating, frequently occurring routines by incorporation of time delays, sabotage of routines, and/or the use of verbal cues. Prompts are faded as the AAC user gains proficiency. (Definition taken from the AAC Institute)
So why do we need to use ALS?
It is very simple we must provide input to children the way we expect them to provide output back to us. If we want to teach a child to speak English we would not speak to them in Spanish, therefore if we want a child to use a form of AAC to communicate we must model for them how to use and in all settings and situations.

Some resources to help us better understand and provide good ALS practice:
Linda Burkhart provides a great presentation on Research Based Practice and ALS that was presented at the Assistive Technology Industry Association (ATIA.) This power point gives examples of how to implement ALS and keep those of us providing input on track.
PrAACtical AAC, one of my favorite AAC resourcesprovides us with Pivotal Skills for AAC Intervention and Aided Language Stimulation.
