Topic Synopsis
This element focuses on developing the learner's ability to use augmentative and alternative communication (AAC) systems to direct others in everyday interactions. Learners practice conveying personal needs, preferences, simple commands, cautionary messages, and positive reinforcement to both familiar and unfamiliar communication partners within known settings. Mastery of these foundational pragmatic skills enhances independence and social participation.
Key Concepts & Core Principles
- AAC systems are divided into two main types: unaided (e.g., gestures, sign language) and aided (e.g., picture symbols, speech-generating devices).
- Low-tech AAC includes tools like communication boards, books, and PECS (Picture Exchange Communication System), which do not require batteries or electronics.
- High-tech AAC involves electronic devices such as tablets with communication apps or dedicated speech-generating devices that produce spoken output.
- Symbols used in AAC can be photographs, line drawings, or text, and must be chosen based on the user's cognitive level and preferences.
- The 'core vocabulary' approach focuses on high-frequency words (e.g., 'go', 'more', 'stop') to maximise communication efficiency.
Exam Tips & Revision Strategies
- Practice role-plays with a variety of partners to build confidence in directing both known and unknown people in familiar settings.
- Ensure you can clearly differentiate between the five communicative functions (needs, choices, instructions, warnings, encouragement) using distinct AAC vocabulary.
- Always check for partner understanding after delivering a message—use a confirmation question or observe their response.
- Use vocabulary that is precise and easily recognizable; avoid ambiguous symbols that could be misinterpreted.
- Prepare for assessment by demonstrating each function at least twice in different scenarios, showing versatility and consistency.
Common Misconceptions & Mistakes to Avoid
- Confusing communicative functions: learners may use a warning symbol when meaning to give an instruction, leading to partner confusion.
- Over-reliance on one familiar communication partner; failing to attempt communication with unfamiliar people during assessment.
- Inconsistent symbol selection: using the same AAC symbol for multiple meanings without clarifying the intended meaning.
- Forgetting to establish joint attention before activating the AAC device, resulting in the partner missing the message.
- Assuming the communication partner understands the AAC system without checking for comprehension or providing additional clarification.
Examiner Marking Points
- Award credit for demonstrating the ability to independently select and use at least two different AAC symbols or messages to express a basic need (e.g., 'thirsty', 'toilet') with a familiar person.
- Assess for evidence of the learner making a clear choice between two options (e.g., 'want juice' vs 'want water') using their AAC system with an unfamiliar person in a role-play scenario.
- Require demonstration of giving a one-step instruction (e.g., 'stop', 'come here') via AAC to both a known and an unknown partner, with correct context.
- Check that the learner can communicate a warning (e.g., 'hot', 'careful') appropriately and the partner responds accordingly.
- Observe the use of encouragement phrases (e.g., 'good job', 'well done') in a social interaction, ensuring the message is timely and relevant.
- Expect the learner to adapt their communication style (e.g., pace, repetition) based on partner familiarity and feedback.
