Using AAC to teach Communication vs Language Development
The difference between using AAC for communication versus language development lies in the purpose, focus and approach.
Key Differences in focus
- Teaching communication with AAC is about giving the child tools to express themselves immediately and effectively.
- Teaching language development with AAC involves systematically building their understanding of language structures and expanding their ability to communicate complex ideas.
Using AAC for Communication Vs Language development
| Aspect | AAC For Communication | AAC For Language Development |
|---|---|---|
| Purpose | To express their immediate needs, wants, thoughts, and feelings effectively. | To develop vocabulary, grammar, and sentence structure. |
| Focus | Practical and functional use of communication | expanding their ability to combine words or symbols |
| Primary Goal | Immediate expression of needs and ideas | Building underlying language structures |
| Examples of goals | 1. Learning to press a button on a device to say "I want water." 2. Pointing to pictures or symbols to express emotions or needs. | 1. Developing sentence-building skills (e.g., combining "want" + "cookie"). 2. Expanding vocabulary and understanding of word categories (e.g., animals, colors). 3. Understanding grammar concepts like plurals, tenses, or pronouns through AAC. |
| Type of Teaching | Context-driven (e.g., in daily activities) | Systematic and developmental (e.g., teaching syntax) |
| Examples of Lessons | Pointing to "drink" when thirsty | Learning to combine "I want" + "drink" |
| Focus on Complexity | Simple and functional | Progressive and developmental |
Key Differences in Strategies
| Aspect | Communication | Language Development |
|---|---|---|
| Focus | Immediate needs and functional use of AAC | Long-term acquisition of vocabulary and rules |
| Modeling | Demonstrating immediate use (e.g., "want water") | Modeling sentence-building (e.g., "I want water") |
| Vocabulary | Core and context-specific words | Expanding categories and word types (e.g., verbs, adjectives) |
| Prompts | Heavily prompted for immediate response | Reduced prompting to encourage independent use |
| Complexity | Single words or simple phrases | Multi-word sentences, grammar, and syntax |
The common approaches for both Communication and Language development are:
- Modelling: Both require consistent modeling and opportunities for practice. What is modelling?
- AAC Integration: Both approaches integrate AAC into daily routines and activities.
- Reinforcement: Positive reinforcement is key to encouraging both communication and language use.
