How AAC Devices End Up in Backpacks

It’s usually not broken batteries and rarely is it a bad evaluation.

One of the top reasons why AAC devices end up in backpacks is that the adults in the room don’t know how to model (and nobody ever taught them.)

What Modeling Is

Modeling on the device is the single most evidence-based strategy we have for AAC acquisition. It works consistently, and it works across ages, diagnoses, and communication levels.

Yet, many classroom teachers and paras have never seen it done because AAC training is almost never built into general education teacher preparation. Paras usually spend the most direct time with AAC users, so why do they receive the least amount of training of anyone on the team?

When an adult doesn’t know what to do with a device, they do the thing humans always do when they don’t know what to do. They quietly stop trying. They hand it to the student and wait. And when nothing happens, they conclude it isn’t working and eventually it finds its way to a backpack.

This is not failure. It’s a knowledge gap.

Here’s What It Looks Like When It’s Working

A para is sitting with a student during snack. She picks up the device, navigates to “want,” says “want” out loud, and touches the symbol. Then she offers two snack options. She waits. The student doesn’t respond for about eight seconds … which feels like a long time. She waits anyway. The student reaches toward the cracker. She models “want cracker” on the device, hands over the cracker, and moves on.

That’s it. No elaborate routine. No perfect response. No proof that anything “worked” in that moment. Just a communication partner showing a student, again and again, what the device can do.

Over time, that repetition becomes familiarity, which becomes reach, which becomes communication.

The research tells us that students whose communication partners model consistently acquire vocabulary faster, generalize more broadly, and communicate more spontaneously.

The One Shift That Changes Everything

If you can only do one thing differently this week, find the person who spends the most unstructured time with your AAC student and teach them one thing.

Just. One. Thing.

Show them how to navigate to one page.

Model one word.

Tell them to try it twice tomorrow without worrying about the outcome. Take out the expectation of a response entirely. Just model and move on.

That’s it. That’s the shift.

The hardest part of building AAC carryover is making the first attempt feel safe enough to try. Once someone has done it once and the world didn’t end, they’ll do it again and again, and that’s how communication partners are made.

If this landed for you, share it with someone else who could benefit from this.
