Many educators, therapists, and communication partners understand that AAC users benefit from seeing language modeled on their device, but it can be difficult to know what modeling looks like during everyday classroom instruction. Questions like “Do I have to model every word?” or “How can I use AAC modeling during lessons?” are common among school teams supporting AAC users.

The short answer is that modeling does not have to be complicated. Small, consistent moments of using the AAC device during natural interactions can make a significant impact on a student’s language development and participation.

What is AAC Modeling?🔗

Modeling, also known as aided language stimulation or aided language input, is an evidence-based strategy used to support AAC students’ language development. It involves a communication partner speaking while pointing to words or symbols on the AAC device so the student can see and hear how communication works in real-life situations.

Just as children learn spoken language by hearing words repeatedly before they begin to talk, AAC users need opportunities to observe others using their system without pressure to respond. When communication partners consistently model the AAC device during interactions, they provide input in the same language the AAC user is learning to express themselves with, which helps to build understanding and confidence over time.

Why AAC Modeling Matters 🔗

AAC modeling plays a critical role in language development because it gives students repeated exposure to how words and symbols are used functionally throughout the day. When a student regularly sees their communication partners using their AAC system, they become more familiar with navigation and vocabulary placement.  Which helps to increase their confidence and reduce frustration during communication attempts.  

Most importantly, when a student watches you model on their device they are encouraged to become more active participants.  Whether that is during an academic lesson or engaging with a peer.   

Practical Strategies for AAC Modeling in the Classroom 🔗

Strategy 1: Focus on Core Vocabulary 🔗

When modeling during academic lessons, it is important to focus on the most meaningful words. Core vocabulary makes up 80% of the vocabulary we use, which is why for most devices those words are located on the home page.  

For example, this week the teacher is reading the book If You Give a Mouse a Cookie. This book has the repetitive line “if you give a mouse a ___, they will want a ___.” 

You can focus on the word “want” by modeling it every time the word is said in the book. You might choose to model only one word like “want”, or you can model the two-word combination of “want + cookie”. 

Choosing just one or two important words helps to keep modeling manageable while providing repetitive exposure. 

Strategy 2: Model During Natural Activities 🔗

AAC modeling should happen during interactions through the school day, not just during academic lessons or in speech therapy.  Communication happens everywhere, which means we should model everywhere! That means during: 

• Lunch 
• Recess 
• Specials – Art, Music, Physical Education 
• In the hallway 
• Transitions between classes 

Strategy 3: Reduce Pressure to Respond 🔗

One of the most important aspects of modeling is remembering that we are modeling using our words. That means that we are not expecting the student to immediately imitate or respond.

Research shows that AAC users benefit from repeated exposure to language without being quizzed or prompted. This ensures that students do not feel frustrated or forced instead; they feel empowered and encouraged. 

Here are ways to reduce pressure:

• Encourage all total communication (e.g. gestures, pointing, facial expressions, vocalizations, words) and then model how to say it on the device so they learn for next time. 

• Use phrases like “great job pointing to the answer! You are telling me ___.” 

Strategy 4:  Allow for Wait Time 🔗

Many students benefit from increased processing time. Depending on the student’s needs, allow opportunities for independent responses by pausing and waiting. In some situations, it may be helpful to model first and then pause to see whether the student engages with the device.

Do the following to ensure more wait stuff:

• No one student answers every question. Give everyone a chance.

• Ask the SLP or teacher how much processing time the student needs, then count in your head. This gives them time and helps remind you to give them an opportunity to respond. 

Common Questions About Modeling AAC 🔗

Model Everywhere!  🔗

Modeling is one of the most powerful tools we have to support AAC users in the classroom. By consistently using the AAC device during everyday interactions, communication partners create a language-rich environment where students can learn communication naturally and without pressure.  

Over time, these small, intentional moments of modeling build understanding, confidence, and independence. When we speak AAC alongside our students, we are not just teaching them how to use a device; we are giving them access to language, connection, and meaningful participation in their world.
