What is AAC Modeling?

(Modeling Without Expectation)

Modeling means using the AAC system to talk to the AAC user by pointing to or pressing words as you speak, WITHOUT making the user to press any buttons.

It's essential for teaching AAC users how to communicate using their systems. We cannot expect children to learn on their own

How to Model:

1. Start Small: Begin with a few words.

2. Match Language Level: Model slightly more complex language (e.g., if they use single words, model 1-2 word combinations).

3. Focus on Key Words: Don’t model every word. Highlight the most important words to convey the message.

“The dog is jumping.” ⟶ dog + jump

“I want to eat pizza” ⟶ eat + pizza

“Where is mom?” ⟶ where + mom + ?

4. Model Regularly: Use the device throughout the day, not just during designated times. Think of daily routines.

Just like we learn to talk by hearing others, AAC users learn by seeing and hearing their systems in use. Consistent modeling helps them understand how to use their AAC devices to communicate real messages.

Overcoming Common Challenges:

Mistakes: It’s okay to make mistakes while modeling; it shows that everyone is learning.
Lack of Response: Keep modeling even if the user doesn’t respond right away. Learning takes time.
User Not Looking: Continue modeling even if the user isn’t directly watching—they’re still learning.
Avoid Just Requests: Model different types of communication, not just requests.
