CHAPTER 12 - LANGUAGE LEARNING AND DEVELOPMENT
3
WHAT WE KNOW ABOUT LANGUAGE DEVELOPMENT IN AAC
USERS
  • Regardless of the cultural, cognitive, social,
    and other factors that influence language
    development, all languages are composed of 5
    domains
  • Pragmatics
  • Phonology
  • Semantics
  • Morphology
  • Syntax

4
Pragmatics
  • It is not unusual to find reports that AAC users
    have impaired pragmatic skills, especially in
    conversational interactions
  • During interactions with speaking partners,
    people who use AAC tend to occupy a respondent
    role
  • they seldom initiate conversations
  • respond primarily when obliged to do so
  • produce utterances that are only as long as they
    need to be to get a message across
  • However, when two people who use AAC interact
    with one another, their conversations are much
    more equal than when they interact with natural
    speakers
  • The phenomenon of conversational asymmetry
    appears to be a function of an imbalance in
    conversational power rather than of pragmatic
    deficits per se in people who use AAC

5
Phonology
  • Although some individuals with SSPI (severe
    speech and physical impairments e.g., cerebral
    pals) are able to analyze and manipulate
    phonologic information successfully, they score
    well below control participants on research
    tasks, regardless of whether other language
    problems are present
  • At least some potential AAC users are at risk for
    delays in the area of phonology, in the absence
    of intervention

6
Semantics
  • Young AAC users often experience delays in
    semantics because
  • They cannot select their own lexicon for their
    AAC displays and rely on adults to make those
    selections, thus, a childs external lexicon
    (i.e., the words on his or her communication
    display) may not reflect his or her internal
    lexicon (i.e., the words in his or her head)
  • They may be talked to less than children who do
    not have disabilities, for a variety of reasons
  • There is an asymmetry between language input and
    output such that children receive and process
    words in one modality (i.e., speech) but
    communicate through another (e.g., manual signs
    or graphic symbols)
  • As they select words from their communication
    displays, they do not receive symbol feedback
    from their partners, particularly if they
    overextend words (e.g., if they use the symbol
    COW to refer to a dog, they might be told the
    correct word verbally No, thats not a cow,
    thats a dog but they are unlikely to be shown
    the correct symbol on their display, even if it
    is there)
  • There may be less convergence between semantic
    and conceptual organization in come graphic
    symbol sets (Blissymbolics) and systems than
    others (e.g., Picture Communication Symbols)
  • The challenge for AAC teams in building semantic
    knowledge is primarily one of providing
    individuals with sufficient access to new
    vocabulary via some type of symbol system and
    then providing ongoing input to build semantic
    knowledge through the use of that system
  • Some individuals who use AAC are able to fast
    map, despite moderate to severe cognitive
    impairments

7
Morphology
  • Individuals who use AAC experience marked
    difficulties with grammatical morphology.
  • It is not clear why people who use AAC regularly
    experience problems with morphology, five
    explanations are possible
  • No experience using them, the symbols the AAC
    user need to indicate (e.g., plural, possessive,
    or past tense) are not available on his or her
    communication display
  • Chooses efficiency over accuracy as a strategy
    for enhancing the speed of communication
  • Not yet learned the morphological rules that
    apply to the situation
  • AAC modality itself influences output and
    precludes the need for conventional English
    morphemes.

8
Syntax
  • Syntactic difficulties of individuals who
    communicate with graphic symbols
  • A predominance of one- or two-word messages, both
    in spontaneous and elicited conditions
  • Use of constituent orders that differ from the
    individuals spoken language background,
    regardless of the AAC modality used
  • Omission of words that appear frequently in the
    individuals language, such as verbs and
    articles, even when available on the
    communication display
  • A prevalence of simple clauses, with limited use
    of complex structures such as questions,
    commands, negatives, and auxiliary verbs
  • Extensive use of multimodal combinations (e.g.,
    gesture symbol, vocalization symbol), word
    overextensions (e.g., dog instead of cow), and
    other linguistic strategies that compensate for a
    lack of necessary symbols
  • Three primary explanations
  • Deficit hypothesis most individuals who use AAC
    systems have underlying deficits, a notion that
    has since been disabused
  • Compensation hypothesis the atypical graphic
    symbol utterance structures reflect constraints
    involved in aided communication
  • Modality-specific hypothesis between what
    individuals who use AAC hear (i.e. spoken
    language) and how they communicate, and are a
    function of the differences between the two
  • It is probable that both the compensatory and
    modality-specific hypotheses contribute to the
    differences seen in the language patterns of
    persons who use AAC

9
In Summary
  • We can make several statements about language
    learning and development in individuals who
    communicate through AAC
  • Many of these individuals show evidence of both
    receptive and expressive language impairments,
    however, it is important to note that many
    individuals who have never been able to use
    natural speech have written and spoken eloquently
    about their experiences and their lives using
    AAC
  • Language difficulties experienced by many
    individuals who use AAC are undoubtedly
    influenced by the fact that their
    language-learning experiences are so very
    different from those of individuals who can speak

10
INTERVENTIONS TO SUPPORT LANGUAGE LEARNING
DEVELOPMENT
  • Graphic Symbols and Language
  • Instructional Strategies and Language Learning
  • Message Units From Sentences to Morphemes
  • Teaching Strategies

11
Graphic Symbols and Language
  • One of the challenges in representing any
    language system for persons who use AAC and do
    not (yet) know how to read involves how to
    translate spoken language into a visual form
    without losing specificity and flexibility, the
    answer depends on whom you ask...
  • Blissymbolics
  • DynaSyms
  • Minspeak
  • Manual Signing

12
  • Blissymbolics The use of this pseudolinguistic
    system allows users to learn about the rules of
    morphology, syntax, and message construction
  • DynaSyms A symbol set used on some dynamic
    display SGDs, including grammatical markers and
    symbols that allow representation of tense,
    plurals, possessives, and other grammatical forms
  • Minspeak AKA semantic compaction, a technique
    to support language which has been debated and
    derived two main questions
  • Is Minspeak a language?
  • Does Minspeak promote language development?
  • Minspeak is not a language. It does not have an
    established rule system, set of icons, or set of
    meanings associated with particular icons,
    rather, its an iconic encoding technique whereby
    symbols are organized so that they can be joined
    together to access a vocabulary with a minimum of
    keystrokes
  • Some believe that Minspeak does promote language
    development because of the similarities among
    semantic compaction, language learning, and
    literacy learning and use
  • Thus, semantic compaction, language, and
    literacy all share the characteristic of being
    generative in nature. Others argue that the
    question is not a fair one because no symbol or
    encoding system itself promotes (or impedes )
    language developmentit all depends on how it is
    taught and used!

13
Manual Signing
  • Linguistic in nature
  • Individuals with a range of disabilities are
    often able to acquire extensive manual sign
    vocabularies in the course of intervention
  • Manual sign learning often stalls at the one-word
    stage of development, especially when individuals
    with cognitive disabilities use it
  • Nonetheless, despite some clear theoretical
    advantages in favor of manual signing as a
    technique for language learning, the research
    suggests that there may be no real advantage to
    using this symbol system rather than others for
    AAC users who can hear.

14
Instructional Strategies and Language Learning
  • By instruction, we mean methods for organizing
    and teaching the use of symbols, in this case, to
    encourage language development
  • Not one best way to do this
  • Little research exists in this area overall
  • Find ways to create links between whichever
    system a person uses for face-to-face
    communication and whichever system he or she uses
    for language and literacy instruction, so that he
    or she is not faced with the daunting task of
    learning completely separate systems for each of
    these domains

15
Organizational Strategies
  • Have the potential to encourage language
    learning
  • Two main categories
  • Grid displays, in which the elements depicted are
    the event, persons, objects,
  • Related actions that are inherent components of
    the scene

16
Organizational Strategies
  • Activity Grid Displays
  • Semantic-Syntactic Display
  • Taxonomic Grid Displays
  • Visual Scene Displays
  • Other Categorical Arrangements

17
  • Activity Grid Displays
  • One of the most popular grid display strategy
    involving the organization of vocabulary
    according to even schemes, routines, or
    activities
  • Many AAC users begin using pictorial or other
    graphic symbol displays that are organized for
    different environments or activities which can
    function as overlays on electronic devices or as
    stand-alone, low-tech communication aids
  • Participation is enhanced when multiple activity
    displays are available
  • Activity displays can also be designed for use by
    individuals across the age range in community,
    school, and vocational settings
  • Advantage facilitators can construct new
    displays relatively quickly using only the
    vocabulary items appropriate to the activity or
    event
  • Activity-based displays are preferable to
    semantic-syntactic displays because they latter
    adds to the cognitive demands of the task for
    individuals who might not think in semantic
    categories
  • Promote the use of multiword linguistic
    structures and build a strong receptive language
    base

18
  • Semantic-Syntactic Display
  • Encourages the AAC user to learn language by
    mapping the symbols according to spoken word
    order and/or usage (i.e. organizing symbols from
    left to right into categories such as who, doing,
    modifiers, what, where, when and so forth with
    frequently used phrases and letters clustered
    along the top or bottom of the display)
  • Taxonomic Grid Displays
  • Grouping symbols according to superordinate
    semantic categories such as people, places,
    feelings, food, drinks and action words
  • Visual Scene Displays
  • Visual scene displays are similar to activity
    displays in that they contain vocabulary words
    associated with specific activities or routines
  • The words in a scene display are organized
    schematically rather than semantically
  • Most appropriate for use with speech-generating
    devices (SGDs) with dynamic screen displays
  • Other Categorical Arrangements
  • Some individuals may have skills that facilitate
    the use of unique categorical arrangements.

19
Message Units From Sentences to Morphemes
  • Message units can range in length from 1 symbol1
    paragraph to 1 symbol1 morpheme marker, in
    between these two extremes are symbols for
    sentences (e.g., a single symbol that means leave
    me alone), phrases (e.g., I want or I dont
    want), and single words

20
Longer message units speed up the communication
process, which is usually slow and cumbersome.
Longer message units require fewer
cognitive/linguistic resources and may be good
for individuals who fatigue easily, are minimally
motivated to communicate, and/or are just
learning to use AAC techniques. Finally, longer
message units permit the person to produce
messages that actually exceed his or her
productive language ability.
How does use of different message unit lengths
affect both long- and short-term language
development?
But longer message units may also impede
communication accuracy. Shorter message units
such as words and morpheme markers, allow more
flexibility in communication. Having
opportunities to manipulate word- and
morpheme-length units is also likely to enhance
language development. Finally, shorter message
units reduces the need for the individual to have
to translate the language he or she hears
(input modality) into the language he or she is
able to use (output modality).
21
Teaching Strategies
  • Structured Approaches
  • Milieu Teaching
  • Interactive Model
  • Aided Language Stimulation and the System for
    Augmenting Language (SAL)

22
Structured Approaches
  • Characterized by adult- or computer-delivered
    discrete trials that are usually conducted with
    one learner at a time
  • Typically, each trial consists of a stimulus
    (e.g., the facilitator holds up a cookie and
    asks, Whats this?), a prompt (e.g. from an
    array of two photographs, a cookie and a shoe,
    the facilitator gestures toward the symbol for
    cookie), a response by the learner (e.g., he or
    she points to the cookie photo) and a reinforcer
    (e.g., the facilitator says good work!)
  • Note the use of a structured teaching approach
    to teach labeling may have some advantages over
    other instructional approaches, especially when
    applied in natural contexts
  • A two- pronged approach is recommended for
    teaching manual signs, with structured discrete
    trial techniques to teach language forms and
    incidental instructional paradigms to teach the
    use of the forms
  • The problem with generalization is one of the
    major disadvantages of structured approaches to
    language intervention

23
Milieu Teaching
  • A naturalistic strategy for teaching functional
    language skills
  • Appears to be more effective than structured
    approaches in promoting early vocabulary
    learning and abstract symbol learning
  • Most reports of successful AAC interventions
    using milieu teaching have been confined to
    individuals at the early stages of language
    development who are learning functional, one-word
    communication skills. Few reports have
    documented the efficacy of milieu teaching to
    develop more complex language with AAC
    techniques.

24
Interactive Model
  • Parent training programs situated within an
    interactive model of language development that
    are designed to teach parents to provide rich
    language input, respond to their childs
    communicative attempts, and encourage the use of
    a variety of language forms and functions
  • Parent training programs The Hanen Early
    Language Parent Program and associated offshoots
    such as More than Words and Allow Me the
    Prelinguistic Milieu Teaching
  • At least in the short term, parents trained
    within the Interactive Model learn to be more in
    tune with their childs abilities, more
    responsive to the childs focus and communicative
    attempts, and less controlling of the childs
    conversational topics
  • Both short- and long-term treatment effects of
    standard Interactive Model interventions are
    usually restricted to increase use of existing
    competencies and do not include acquisition of
    new communication and/or language skills
  • Interactive Model programs, which are widely used
    in North America, can be applied to successfully
    to at least increase communication opportunities
    for beginning AAC users.

25
Aided Language Stimulation and the System for
Augmenting Language (SAL)
  • Both designed specifically for AAC applications
    and based on milieu teaching with several
    additional elements
  • Both are total-immersion approaches to teaching
    individuals to understand and use graphic symbols
    with the purpose of providing learners with
    models for combining symbols in a flexible manner
    and opportunities to do so
  • Based on the premise that by observing graphic
    symbols being used extensively by others in
    natural interactions, the learner can begin to
    establish a mental template of how symbols can be
    combined and recombined generatively to mediate
    communication during the activity.
  • Both are intended to teach the AAC learner to use
    language in a very natural way that eliminates
    the need for more structured training
    interventions, because they mimic the way natural
    speakers learn to comprehend language

26
Aided Language Stimulation
  • A facilitator highlights symbols on the users
    communication display as he or she interacts and
    communicates verbally with the user, similar to
    the total communication approach used to teach
    manual signs to individuals with hearing or other
    impairments
  • Also incorporates a variety of techniques for
    eliciting communication using symbols and other
    AAC modes. Nonverbal juncture cues are nonverbal
    signals (achieved via facial expression, gesture,
    body posture) performed by the facilitator that
    precede the highlighting of a symbol on the
    communication display.
  • The cues serve two functions
  • They code the target symbol in nonverbal form
  • They help the individual to anticipate symbol
    selection by providing a brief time delay during
    which the individual might jump ahead of the
    facilitator and select the symbol spontaneously

27
System for Augmenting Language (SAL)
  • AKA Augmented Communication Input
  • Similar to aided language stimulation, with two
    notable exceptions
  • The use of an electronic voice-output
    communication device is considered a critical
    component of the intervention
  • SAL techniques are much simpler than the
    elaborate procedures for augmented input and
    elicitation used in aided language stimulation
  • Similar to aided language stimulation, with two
    notable exceptions
  • The use of an SGD is a critical component of the
    intervention
  • SAL techniques are much simpler than the
    elaborate procedures for elicitation used in
    aided language stimulation
  • Communication displays using graphic symbols with
    a printed word gloss are constructed for the
    learners SGD, and communication partners learn
    to activate symbols on the device to augment
    their speech input in naturally occurring
    communication interactions.
  • A 2 year longitudinal study of SAL showed
  • Generalized use of their communication devices
    with both familiar and unfamiliar adults and
    peers without disabilities in a variety of
    environments
  • Students learned to use arbitrary symbols in
    combination with gestures and vocalizations to
    request items, assistance, and information to
    make comments and to answer questions, among
    other functions
  • Meaningful and functional symbol combinations
    spontaneously emerged in the repertoires of 10 of
    the 13 participants

28
CHAPTER 13 - LITERACY DEVELOPMENT OF CHILDREN WHO
USE AAC
29
  • Most individuals consider reading and writing
    skills to be a valued component for successful
    participation in society. These skills allow them
    to use literacy as a tool for communication,
    critical thinking, and the attainment of social
    and cultural power.

30
Primary Motor Impairments/Severe Speech and
Physical Impairments (SSPIs)
  • Includes individuals with congenital impairments
    such as cerebral palsy and arthrogryposis, as
    well as people with acquired impairments (e.g.,
    spinal cord injuries)
  • The greatest barrier to literacy learning may be
    reduced opportunities to engage in authentic
    reading and writing opportunities and erroneous
    beliefs that individuals with SSPIs are not
    capable of learning to read and write
  • Lack of knowledge about literacy curricula and
    supports to literacy learning has been one of the
    critical challenges in supporting the literacy
    learning of students who use AAC

31
Handwriting/Fine Motor Impairments
  • Dysgraphia inhibit the mechanics of producing
    words on paper
  • This difficulty with handwriting may be related
    to underlying fine motor control or eye-hand
    coordination problems, visuospatial impairments,
    or attention deficits
  • Many students with fine motor impairments also
    experience learning disabilities, specific
    language impairments, and/or cognitive impairments

32
Specific Language Impairment
  • Is considered to be a primary, rather than a
    secondary, disorder in that it is not the result
    of mental retardation, autism, or other
    etiologies
  • Considerable attention has focused on describing
    a heterogeneous group of children who have
    considerable difficulty with spoken receptive and
    expressive language
  • Specific language impairment, childhood aphasia,
    developmental aphasia, dysphasia, and language
    disability, among others, have been used
    interchangeably to refer to the problems that
    children experience

33
Learning Disabilities
  • A variety of names used, including
    language-learning disabilities, dyslexia, minimal
    brain dysfunction, and specific reading
    disabilities, among others.
  • The national Joint Committee on Learning
    Disabilities uses the following definition
  • Learning disabilities is a general term that
    refers to a heterogenous group of disorders
    manifested by significant difficulties in the
    acquisition and use of listening, speaking,
    reading, writing, reasoning, or mathematical
    abilities.
  • These disorders are intrinsic to the individual,
    presumed to be due to a central nervous system
    dysfunction, and may occur across the life span.
  • Problems in self-regulatory behaviors, social
    perception, and social interaction may exist with
    learning disabilities but do not by themselves
    constitute a learning disability.
  • Although learning disabilities may occur
    concomitantly with other handicapping
    conditions...or with extrinsic influences...they
    are not the result of those conditions or
    influences.

34
Cognitive Impairments
  • People whose intellectual abilities lag behind
    their same-age peers
  • The severity may vary widely across individuals
    and is usually established in terms of an
    individuals scores on both norm-referenced
    intelligence tests and adaptive behavior scales
  • When making decisions about literacy instruction,
    consider not only the impairment itself but any
    additional learning needs that might be present
  • Many children with cognitive impairments can
    develop both emergent and conventional literacy
    skills and should receive access to the same
    instructional opportunities as typically
    developing children

35
Visual Impairments
  • The vast majority of these individuals are not
    totally blind, it is estimated that 80 of all
    individuals classified as legally blind have
    residual vision that is sufficient for use as a
    primary learning channel for reading, writing,
    and other school activities
  • Assessment involves specialized vision tests that
    evaluate a number of components including visual
    acuity, visual field magnitude, oculomotor
    functioning, light and color sensitivity, and
    visual stability
  • Approximately 50-60 of school-age individuals
    with VI have additional impairments, with
    physical and/or intellectual abilities occurring
    most often
  • Educational adaptations for this population
    should consider use of enlarged text, enlarged
    keyboards, screen magnifiers, speech output text
    readers, or braille

36
Autism Spectrum Disorders
  • As you know
  • As many as 40-60 of children with ASD do not use
    speech as their primary mode of communication
  • Some of these individuals have significant
    strengths in word recognition (e.g., hyperlexia)
    and relative deficits in comprehension that are
    evidenced across language and literacy

37
Emergent Literacy and Literacy Development
38
Early Literacy Experiences of Typically
Developing Children
  • The home environment is important in laying the
    foundation for success in literacy
  • Literacy learning is thought by many to begin at
    birth, as writing, reading, speaking, and
    listening skills develop simultaneously
  • Across both home and school environments, the
    literacy experiences of children who use AAC are
    distinctly different from those of typical
    children
  • A large part of becoming literate is learning the
    functions of literacy, simply having exposure to
    favorite books, children learn a host of
    literacy concepts - story schema, plot
    structure, anticipation of events, memories from
    previous readings, and ways in which story
    language creates emotions such as surprise and
    humor

39
Early Literacy Experiences of Children with
Severe Communication Impairments and those who
use AAC
  • Substantial differences exist between the
    experiences of children who do and do not have
    disabilities in learning to read One survey
    found that although parents of preschoolers
    without disabilities reported that they read to
    their children daily, parents of children with
    SSPIs read to their children, on average, two to
    three times per week
  • Factors that influence literacy development in
    children with severe communication impairments
  • Many parents of children who use AAC report that
    they primarily focus their priorities on
    communication and meeting the childrens physical
    needs, in contrast, parents of typically
    developing children place the highest priorities
    on communication, making friends, and literary
    activities
  • Children who use AAC often have difficulty
    manipulating and playing with literacy materials
    (e.g., selecting books, turning pages of books,
    playing with pencils and crayons) because of
    their motor impairments
  • Positioning and seating difficulties, paired
    with vision impairments, may make it difficult
    for these children to see the illustrations while
    their parents and teachers read to them which,
    in turn, influences the quality of the
    interactions during storybook reading activities
  • Language and cognitive factors affect the
    development of play skills related to literacy
    (e.g., pretending to read), and parent modeling
    of literacy opportunities may be less frequent
    because the child is less mobile
  • Children may also be unable to provide their
    parents with feedback related to their level of
    understanding as well as their preferences
  • Classroom literacy learning experiences have also
    been found to be substantially different for
    school-age students who use AAC compared with
    their typically developing peers, instruction
    differs not only in quantity but also in quality
    and amount of time spent engaged in literacy
    tasks.

40
RELATIONSHIP BETWEEN LANGUAGE KNOWLEDGE AND
LITERACY LEARNING
41
Early Literacy Support
  • Three main principles of child learning should
    guide activities
  • activities should be child directed and
    interactive, with the parent following the
    childs lead
  • parents should consider learning to be a
    constructive process in which the child
    participates actively and is supported to map
    previous knowledge onto new experiences
  • literacy tasks should be meaningful, goal
    directed, and embedded in purposeful activities.

42
Reading and Storytelling
  • Strategies family members, teachers, and others
    can use to encourage the development of literacy
    skills
  • Read age-appropriate stories aloud frequently and
    repeatedly, young children enjoy hearing the same
    story over and over- repetitive reading helps
    children to see that all stories contain a
    predictable structure (pattern)
  • Involvement in story times such as those
    sponsored by many libraries, as well as by
    visiting the library with the child to borrow
    books from an early age
  • AAC users need integrated communication and
    literacy activities that allow them to engage in
    active, meaningful interactions about texts
  • It is essential that AAC users master
    considerable language knowledge before entering
    the elementary grades, the development of
    conventional literacy skills is inextricably
    linked to the potential of their language and
    communication systems

43
Writing and Drawing
  • Children also need opportunities to learn
    writing, drawing, and other composition skills
    that involve the use of output tools

44
Augmented Reading and Writing
  • Emergent literacy computer programs for young
    children are available to teach language and
    preliteracy skills to young children that provide
    AAC users with access to materials that foster
    critical reading skills, (e.g., grapheme-phoneme
    awareness).
  • Emergent reading software offers
  • Opportunities to develop skills in visual
    discrimination, letter naming, letter recognition
    and recall, sight word recognition, spelling, and
    phonics (e.g., letter-sound combinations)
  • Access to basic decoding and writing functions,
    such as sounding out words inventing word
    spellings, and engaging in early writing that is
    legible, (e.g., writing names of family members,
    writing familiar environmental print such as Stop
    or Exit)
  • Access to drawing tools or picture dictionaries
    to produce story illustrations.

Graphic Symbols and Language Development
  • Most young children with SSPIs who cannot speak
    are also unable to read and spell in order to
    prepare their messages
  • Many of these students must focus on the
    simultaneous acquisition of three modes of
    communication-speech, graphic symbols, and
    orthography
  • Instructors should consider overlapping features
    of the three modes and utilize instructional time
    as a means to foster integration of concepts
    across modes
  • Through exposure to print children learn
  • that print conveys meaning
  • that there is directionality to the way we read
  • a basic understanding of the concepts of words,
    letters, and sounds
  • that the words we speak are mapped onto print and
    there are certain patterns in speech-to-print
    correspondence
  • that each letter has a shape and a name
  • that letters can represent sounds

47
Graphic Symbols Cont.
  • There are several important skills related to the
    influence of language abilities on reading
    comprehension. These critical variable include
  • phonological processing skills
  • word recognition abilities
  • problem-solving skills
  • lexical processing abilities
  • syntactic awareness
  • semantic knowledge
  • narrative discourse processing skills
  • Difficulty with any one of these skills may have
    an impact on the individuals ability to
    comprehend text
  • Frequent exposure to graphic symbols and
    orthography may not automatically give students
    who rely on AAC an upper hand in the early
    stages of literacy

48
The contributions of graphic symbols to literacy
learning
  • When learning AAC symbols, children develop the
    knowledge that symbols convey meaning, and they
    may be able to transfer this concept to
    understand that print also conveys meaning
  • When communication displays support left-to-right
    progressions, children may also learn the concept
    of print directionality
  • When symbols are paired with traditional
    orthography, children who use AAC are exposed to
    the concept of words
  • When facilitators draw attention to the concept
    of letters, and communication displays utilize
    sound symbol mapping rules, knowledge of words,
    letters, and sounds may be fostered
  • Symbols are presented at the whole-word level, so
    the ability to recognize words out of context,
    and to discriminate individual letters through
    paired associative learning (i.e., letter-phoneme
    associations and speech-to-print matching) is not
    facilitated
  • Because symbols are not orthographic in nature,
    they are unlikely to teach children who use AAC
    that letters have shapes and names and that
    letters can represent sounds

49
The relationships between graphic symbols and
reading comprehension
  • Phonological awareness skills in students who use
    AAC also play a role in facilitating word
    recognition and thus support their ability to
    understand text
  • For students who use AAC, word knowledge relates
    directly to the availability of symbols to
    communicate, the more symbols the student has,
    the more vocabulary words he or she can
    manipulate and use
  • Graphic symbols play a role in supporting
    syntactic awareness and competence if
    facilitators or teachers teach the student who
    uses AAC to integrate symbols into sentence
    sequences
  • Pragmatic awareness ability to recognize
    relationships between groups of sentences, to
    create on overall representation of the
    sentences, and to use prior knowledge to gain the
    full meaning of a passage. This skill develops
    through experience with written paragraphs, thus
    the influence of graphic symbols on comprehension
    at this level is unclear

50
Graphic Symbols and Reading Acquisition
  • Print Conveys Meaning
  • When learning AAC symbols, children develop the
    knowledge that symbols convey meaning, and they
    may be able to transfer this concept to
    understand that print also conveys meaning.
  • Directionality of Print
  • When communication displays support left-to-right
    progressions, children may also learn the concept
    of print directionality.
  • Words, Letters, and Sounds
  • When symbols are paired with traditional
    orthography, AAC users are exposed to the concept
    of words. In order to emphasize this concept, as
    well as to draw attention to the concept of
    letters, facilitators can teach AAC users to
    relate the words on their communication displays
    with written text.
  • Graphic symbols are unlikely to teach AAC users
    that letters have shapes and names and that
    letters can represent sounds because the symbols
    are not orthographic in nature, graphic symbol
    use will teach these concepts only if the AAC
    user communicates with the symbol set in
    combination with traditional orthography and if
    the facilitator directs the users attention
    toward the sound system of language.

51
Graphic Symbols and Reading Comprehension
  • Phonologic Processing Skills
  • When readers can identify words rapidly, they can
    allocate greater cognitive resources to the
    higher level processes involved in comprehension.
  • Word Knowledge
  • For AAC users, word knowledge directly relates to
    the availability of symbols to communicate-the
    more symbols an AAC user has, the more vocabulary
    words he or she can manipulate and use.
    Vocabulary is also a critical factor in reading
    comprehension-the more word meanings a person
    knows, the more language he or she can
    understand, either aurally or visually.
  • Syntactic Awareness
  • Researchers have hypothesized that graphic
    symbols support literacy learning by providing
    learners with information about the structural
    aspects of language.
  • Pragmatic Awareness
  • Pragmatic awareness is the ability to recognize
    relationships between groups of sentences, create
    an overall representation of the sentences, and
    use prior knowledge to gain the full meaning of a
    passage.
  • Because this skill develops through experience
    with written paragraphs, the influence of graphic
    symbols on comprehension at this level is
    unclear. To facilitate pragmatic awareness, the
    AAC system must allow the user to draw
    inferences, use metaphors and similes, and foster
    audience awareness.

52
Augmented Reading and Referencing
  • Instructional Techniques
  • Educators rely on many instructional approaches
    to teach reading skills to all children. These
    methods include various phonics approaches,
    direct instruction tactics (DISTAR), language
    experience techniques, whole language
    approaches, the Orton-Gillingham method, and
    many, many others.

53
Technology-Supported Writing
  • Instructional Techniques
  • Strategy Instruction
  • Augmented Writing
  • Alternative Access

54
  • Instructional Techniques
  • The current philosophy about writing development
    emphasizes that students learn to write by
    writing
  • Strategy Instruction
  • Given the slow writing rates of many AAC users,
    it is important to implement strategies to
    support all phases of the writing process. By
    using one method of explicit skill instruction,
    known as strategy instruction, teachers can aid
    beginning writers in developing problem-solving
    skills for approaching academic tasks.
  • Students who participate in strategy instruction
    intervention in which teachers convey information
    about good writing and model it, appear to gain
    greater awareness of the writing task, learn
    strategies for approaching writing, and are able
    to generalize these skills to other writing tasks
  • Augmented Writing
  • Individualized literacy supports, both
    technological and instructional, address
    individual student needs by providing varying
    levels of assistance and graduated independence
  • In the next phases of literacy scaffolding, the
    student begins to use alternative modes of
    writing access and/or engage in greater degrees
    of independent writing
  • Alternative Access
  • School personnel can utilize a backwards
    elimination approach to determine the writing
    adaptations needed by an individual student, the
    teacher simply works backward from the standard
    materials and procedures that students without
    disabilities use. Thus, initial adaptations
    might involve modifications of worksheets or
    textbooks.
  • If simple solutions to participation prove
    ineffective, the backwards elimination approach
    requires that the teacher then try low-tech
    adaptive equipment or materials as solutions

55
CHAPTER 14 - EDUCATIONAL INCLUSION OF STUDENTS
WHO USE AAC
56
PREPARING AAC USERS FOR THE CLASSROOM
  • Begin providing AAC services to children with
    severe communication disorders during their
    preschool years
  • AAC team members involved with preschool students
    must have a solid understanding of the
    participation requirements of elementary school
    programs in order to adequately prepare children
    for these environments

57
Transition to Elementary School
  • The ultimate goal of communication and other
    interventions for young children is to facilitate
    their entry into general education environments
  • It is important to ensure that by the time the
    child reaches the first grade, he or she has the
    tools necessary for academic participation and
    instruction, tools may include an augmented
    writing system (either electronic or
    nonelectronic) in addition to whichever spoken
    communication system the child uses, computer or
    software technology necessary for formal
    augmented reading instruction
  • To facilitate a smooth transition to
    kindergarten, visit the target classroom well
    before the beginning of the school year in order
    to gather information about the participation
    patterns of typical children in that setting
  • Interventionists and educators must manage
    transitions between kindergarten and elementary
    school with care and systematic planning
  • First, the AAC team should not modify the AAC
    system unnecessarily during the first year of
    school
  • Second, the AAC team in the elementary school
    should have the knowledge and skills to
    facilitate communication efforts of young AAC
    users

58
INVOLVING STUDENTS IN THE GENERAL CURRICULUM
  • Negative consequences may result if inclusion
    does not occur
  • Teachers (often special educators) must develop
    personalized educational plans to meet their
    needs and deliver this instruction either in a
    segregated setting (e.g., a resource room, a
    special education) or in the general classroom
    during activities that are parallel to, but not
    the same as, those for other students
  • Reduces available peer pressure and support
  • Diminishes opportunities for peer interaction and
    instruction, even if a student with disabilities
    is physically present in a general classroom,
    opportunities for social and academic involvement
    with other students are reduced if he or she has
    a personalized curriculum
  • May shape students perceptions of themselves
    negatively and may also foster negative
    impressions of the students in the eyes of their
    classmates, teachers, and family members

59
THE PARTICIPATION MODEL
  • We use the Participation Model as a framework for
    making decisions associated with including AAC
    users in general educational programs

60
Identify Participation Patterns
  • Academic Participation
  • Competitive
  • Active
  • Involved
  • None
  • Social Participation
  • Competitive
  • Active
  • Involved
  • None

61
Academic Participation
  • Competitive
  • Competitive academic participation requires that
    a student with AAC needs meet the academic
    standards expected of peers who do not use AAC
  • Active
  • Not all students with AAC systems can be
    academically competitive in all areas,
    nevertheless, many students can be academically
    active and participate in the general curriculum,
    although they may not be able to meet the same
    academic standards as their peers
  • Involved
  • Some students, together with their educational
    teams and parents, may decide that participation
    in certain academic areas will be limited to
    academic involvement, rather than competitive or
    active participation. In this case, the student
    attends general class activities along with peer
    students but participates less actively in the
    general curriculum.
  • None
  • The level of no academic participation is never
    acceptable or defensible, although it occurs far
    too often

62
Social Participation
  • Competitive
  • Socially competitive students are active
    participants in a social group of peers, they are
    involved in the activities of the group, at least
    by choosing whether to engage in activities, and
    exert influence over group decisions
  • Active
  • Not all students with or without disabilities are
    socially competitive, but many are socially
    active. They make choices about and are involved
    in social activities, although they may not exert
    much influence over the social climate of a group
    and its interaction patterns.
  • Involved
  • Students who are socially involved attend class
    with their peers who do not have disabilities and
    may be involved in some extracurricular
    activities
  • None
  • Students who have no social participation have
    limited access to their peers during school hours
    and thus have no opportunities to form
    friendships or make acquaintances

63
Activity/Standards Inventory and Barrier
Assessment
  • The first step is completing an
    activity/standards inventory in the classroom at
    the beginning of the school year. This inventory
    involves a detailed list of all activities that
    typical students are expected to complete during
    the school day, along with expected levels of
    academic participation.

64
Assess Opportunity Barriers
  • First, we consider a variety of opportunity
    barriers that may interfere with inclusion
    efforts. It is often helpful to identify
    opportunity barriers during a team meeting among
    representatives of the family, educational staff,
    and educational administrators.

65
Assess Barriers to Access
  • Assess the Communication Patterns and Vocabulary
    Requirements of the Classroom
  • Teacher-Directed Large-Group Instruction
  • Teacher-Directed Small-Group Instruction
  • Sharing Time
  • Cooperative Group Instruction
  • One-to-One Interactions

66
Teacher-Directed Large-Group Instruction
  • 10 unofficial rules that guide most
    teacher-directed large-group instructional
    activities
  • Teachers mostly talk and students mostly listen,
    except when the teacher grants permission to
    talk
  • Teachers give cues about when to listen closely
  • Teachers convey content about things and
    procedures about how to do things
  • Teacher talk gets more complex in the upper
    grades
  • Teachers ask questions and expect specific
    responses
  • Teachers give hints about what is correct and
    what is important to them
  • Student talk should be brief and to the point
  • Students should ask few questions and keep them
    short
  • Students talk to teachers, not to other students
  • Students can make a limited number of spontaneous
    comments, but only about the process or content
    of the lesson

67
  • Teacher-Directed Small-Group Instruction
  • Usually, the purpose of small-group instruction
    is to develop language, literacy, and thinking
    skills, with an emphasis on comprehension of text
    material and verbal expression
  • Sharing Time
  • Teachers usually employ a sharing format for
    current events presentations, reports, and
    show-and-tell activities. People use language,
    sharing contexts primarily to describe events in
    a logical and temporal sequence, usually in past
    tense
  • Cooperative Group Instruction
  • Researchers have a poor understanding of the
    interactions that occur in the context of
    cooperative learning. In a cooperative learning
    group, there is often no designated leader.
    Thus, communication patterns among students in
    such groups appear to resemble more closely those
    that occur in peer conversational interactions
    than those that occur during teacher-led group
    instruction.
  • One-to-One Interactions
  • The AAC user will need specific vocabulary words
    related to educational activities as well as
    vocabulary to manage conversational interactions
    that occur on a one-to-one basis

68
Assess Teacher Style
  • Augmenting Comprehension
  • Mapping Language
  • Pooling Responses
  • Bidding for Response Opportunities

69
  • Augmenting Comprehension
  • During assessment, it is useful to determine
    whether the specific augmented comprehension
    strategies used by a teacher will be useful to
    the particular AAC student who may be placed in
    that classroom.
  • Mapping Language
  • During classroom assessment, AAC teams need to
    address the question of how often a teacher maps
    language and the strategies that he or she uses
    to do so.
  • Pooling Responses
  • Teachers vary widely in the strategies they use
    to pool potential responses for their students by
    providing multiple response options. Some
    teachers augment comprehension regularly with
    tangible objects, photos, or illustrations.
  • Bidding for Response Opportunities
  • Finally, teachers vary considerably in the ways
    they expect their students to bid for response
    opportunities in the classroom. Some may call on
    specific children and prefer to have one child
    respond at a time. Others may expect the
    children who know the answer to bid for a turn by
    raising their hands the teacher then selects a
    student to respond.

70
Assisting Students to Manage Time Constraints
  • Students with severe communication and motor
    impairments often find it difficult to keep up
    with the pace of a general classroom because they
    have difficulty manipulating educational
    materials such as books and worksheets
  • Advance Preparation
  • Use of Peer Instruction
  • Adapting Academic Testing
  • Reduced Workloads
  • Selective Retention

71
  • Advance Preparation
  • It may be necessary for AAC teams to work with
    general education staff to preview upcoming
    assignments, topic areas, and class projects, so
    that they have ample time to create related
    adaptations
  • Teachers can encourage students who use AAC to
    prepare questions in advance or compose their
    answers to assigned questions at home in order to
    compensate for their reduced communication rates
  • Use of Peer Instruction
  • Applying cooperative or peer instruction
    approaches to students who use AAC systems can be
    very effective in helping them meet classroom
    time demands
  • Adapting Academic Testing
  • If adjustments in time limits are not made, these
    students are either penalized for their
    disabilities or must rely on the assistance of a
    paraprofessional to complete tests in the time
    allotted
  • Reduced Workloads
  • Students who are expected to participate at a
    competitive level (i.e., held to the same
    standards as their peers without disabilities) do
    not necessarily have to complete the same amount
    of work as their peers
  • Some students and families favor the selective
    participation strategy of not enrolling in
    classes that are not required or for which the
    student can meet the requirements in a different
    way
  • Selective Retention
  • In the United States, children with disabilities
    are eligible to remain as public school students
    past the age of 18 when most of their peers
    graduate. This extra time for students who use
    AAC systems means that rather than rushing
    through an educational program at the same pace
    as their peers without disabilities, they and
    their families may opt for retention at a grade
    level in order to meet specific academic goals.
