Literacy Development and AAC Integration

Early Literacy Foundations

  • Print Awareness: The ability to distinguish print from non-print stimuli and understand its purpose and function in the environment. This includes knowing that print carries meaning, that books are read from front to back, and that text is read from left to right and top to bottom.

    • Activities: Drawing attention to print on a page, pointing to words while reading, looking at environmental print (e.g., street signs, labels for food).

    • Parental Role: Parents are encouraged to track their reading with their finger to show children where their eyes are going on a page, reinforcing the directionality of print and one-to-one correspondence between spoken and written words.

Components of Literacy Development

  • Letter Identification: Recognizing different forms of print (uppercase and lowercase) and associating them with specific letters of the alphabet. This is a foundational skill for reading and writing.

    • Often hand-in-hand with letter sounds, but initial focus is just on identifying the distinct letter forms (e.g., recognizing "A" and "a" as the same letter).

    • Involves distinguishing between letters (e.g., "b" vs. "d") and understanding that letters are symbols representing sounds.

  • Phonological Awareness: Understanding that spoken language is made up of individual sounds (phonemes) and that these sounds can be recognized, manipulated, and changed. It's an auditory skill that doesn't involve print.

    • Concepts: Sounds can be blended (e.g., /c/ /a/ /t/ makes "cat"), segmented (e.g., "cat" can be broken into /c/ /a/ /t/), put together, or taken apart. This also includes rhyming, alliteration, and syllable segmentation.

    • Key Idea: Sounds do not exist in isolation; they work together to create new sounds and representations, forming words.

  • Decoding: The process of translating written words into spoken words by applying knowledge of letter-sound relationships (phonics) and word patterns. It is the bridge between phonological awareness and reading comprehension.

    • Involves sounding out words to understand their pronunciation and meaning.

    • Example: A child uses their knowledge that "c" makes the /c/ sound, "a" makes the /a/ sound, and "t" makes the /t/ sound to read the word "cat."

    • Essential for developing fluency and accessing the meaning of unfamiliar words.

Strategies for Using AAC Devices for Children with Language Difficulties

Augmentative and Alternative Communication (AAC) devices are tools and strategies that people use to solve communication challenges. For children with language difficulties, AAC can provide a voice and facilitate expression.

1. Direct Instruction and Modeling

  • Modeling: The most effective strategy involves consistently modeling the use of the AAC device in various contexts. Adults should use the device to communicate with the child, demonstrating how to formulate messages, navigate pages, and express different communicative functions (e.g., requesting, commenting, protesting).

    • This can be done by 'pointing and speaking' or 'typing and speaking' simultaneously.

  • Direct Teaching: Explicitly teach the child how to access specific vocabulary, build sentences, and use different communication functions on the device.

    • Start with core vocabulary (high-frequency words like "go," "want," "more") as they are versatile and can be used in many situations.

2. Creating Communication Opportunities

  • Environmental Arrangement: Set up the environment to encourage the child to use their AAC device.

    • Place desired items out of reach, but within sight, to prompt requesting.

    • Provide choices (e.g., "Do you want apple or banana?") using the AAC device as the response medium.

  • Communication Temptations: Strategically withhold items, offer incomplete items, or present unexpected situations to motivate the child to communicate using their device.

    • For example, giving only one block when building a tower, prompting the child to request "more."

3. Encouraging Spontaneous Communication

  • Wait Time: Allow ample wait time (5-10 seconds) after asking a question or making a comment to give the child sufficient time to formulate a message on their device.

  • Acknowledge All Attempts: Respond positively to all communication attempts, even if they are unclear or only partially correct. This reinforces the value of their communication.

  • Expand on Communication: When a child communicates a message (e.g., "juice"), expand upon it (e.g., "Oh, you want more juice!") to model more complex language and vocabulary.

4. Device Management and Customization

  • Regular Updates: Ensure the AAC device's vocabulary and settings are regularly updated to reflect the child's developmental stage, interests, and current communication needs.

  • Personalization: Customize the device with familiar photos, personal experiences, and high-interest vocabulary to increase motivation and engagement.

  • Troubleshooting: Teach the child and caregivers basic troubleshooting skills to address minor technical issues, ensuring consistent access to communication.

These strategies aim to integrate AAC use into daily routines, making it a natural and effective mode of communication for children with language difficulties.
