Chapter 4: Component 1 - Augmentative and Alternative Communication (AAC) Fundamentals Guide

4.1. Introduction to the Component

The first component of the AAC-Inclusion toolkit forms the basis of the entire system. It aims to provide users — teachers, parents, and professionals — with a clear, accessible, and directly actionable understanding of Augmentative and Alternative Communication (AAC).

Indeed, the effectiveness of the tools proposed in the other components depends heavily on the ability of adults to understand the principles of AAC and to apply them consistently.

This component directly addresses a need identified in the survey: a lack of practical training and clear benchmarks on AAC

4.2. Why is AAC essential?

In many situations, children with communication difficulties face a double barrier:

●        they cannot clearly express their needs

●        they are not always understood by those around them

This situation can lead to:

●        frustration

●        Social withdrawal

●        maladaptive behaviors

AAC helps to remove these barriers by providing alternative means of communication that are accessible and understandable.

Concrete example

A child who wants to drink but cannot communicate clearly:

●        crying

●        screaming

●        Pull an adult

With the AAC, he can simply: point to a "DRINK" card

Result :

●        The message is clear

●        Frustration decreases

●        Interaction becomes positive

4.3. The different types of AACs

AAC is not limited to a single tool. It includes several complementary forms.

1. AAC without help (natural low-tech)

It includes: gestures, facial expressions, pointing, body expressions.

●        Advantage: immediate and accessible

●        Limit: sometimes insufficient for complex messages

2. AAC with visual aids (low-tech)

It includes: pictograms, images, photos, visual cards.

●        Advantage: Stability and clarity

●        Widely used in the toolkit

The pictograms from ARASAAC are particularly recommended for their standardization.

3. AAC with digital tools (high-tech)

It includes: AAC apps, tablets, text-to-speech devices

●        Advantage: great expressive richness

●        Limit: requires equipment and accompaniment

4.4. Preconceived ideas about AAC

The survey revealed several misconceptions that need to be corrected.

"AAC prevents the child from speaking"  🡪 False

On the contrary, AAC often promotes the emergence of oral language.

"It's too complicated to set up" 🡪 False

With simple tools (cards, pictograms), implementation can be very accessible.

"It's reserved for serious cases" 🡪 False

The AAC can be used temporarily or partially.

Conclusion

AAC is an enabling tool, not a permanent replacement.

4.5. The basic principles of use

To be effective, the AAC must follow certain rules.

1. Modeling

The adult must demonstrate how to use the tools.

Example: The teacher shows the card "PLAY" while saying the word.

2. Active Standby

After offering a support, it is necessary to: give the child time

3. Positive reinforcement

Any attempt at communication must be valued, even if it is partial.

4. Repetition

Learning is based on: repetition in different contexts

5. Generalization

The tools must be used:

●        at school

●        at home

●        in the activities

4.6. How to choose the right tools?

The choice of tools must be adapted to each child.

Main criteria

●        Age

●        level of understanding

●        Motor skills

●        Environment

Example

●        Beginner child → single cards (2 choices)

●        Advanced child → structured board

4.7. Role of the adult in support

The adult is not only an observer: he is  an actor in communication.

Role of the teacher

●        Integrating AAC into operations

●        adapt the materials

●        Encourage participation

Role of the parent

●        Use the tools on a daily basis

●        Create communication situations

●        Reinforcing learning

Importance of consistency

When both environments use the same tools: progress is faster

4.8. Common mistakes to avoid

Too many tools at once: risk of confusion

Lack of modelling: the child does not know what to do

Lack of consistency: loss of efficiency

Constantly changing pictograms: loss of reference points

4.9. Mini Practical Guide (Operational Summary)

To get started:

1. Choose 2–3 cards
2. use them in a simple situation
3. Model
4. Wait
5. encourage

Repeat every day

4.10. Conclusion

This first component forms the basis of the AAC-Inclusion toolkit.

It allows you to:

●        Understanding AAC

●        Avoid mistakes

●        Laying the foundation for effective implementation

It thus prepares the user to fully exploit the tools presented in the following chapters.
