2CHAPTER 12 - LANGUAGE LEARNING AND DEVELOPMENT
3WHAT 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
4Pragmatics
- 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
5Phonology
- 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
6Semantics
- 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
7Morphology
- 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.
8Syntax
- 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
9In 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
10INTERVENTIONS TO SUPPORT LANGUAGE LEARNING
DEVELOPMENT
- Graphic Symbols and Language
- Instructional Strategies and Language Learning
- Message Units From Sentences to Morphemes
- Teaching Strategies
11Graphic 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!
13Manual 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.
14Instructional 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
15Organizational 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
16Organizational 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.
19Message 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
20Longer 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).
21Teaching Strategies
- Structured Approaches
- Milieu Teaching
- Interactive Model
- Aided Language Stimulation and the System for
Augmenting Language (SAL)
22Structured 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
23Milieu 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.
24Interactive 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.
25Aided 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
26Aided 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
27System 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
28CHAPTER 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.
30Primary 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
31Handwriting/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
32Specific 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
33Learning 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.
34Cognitive 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
35Visual 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
36Autism 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
37Emergent Literacy and Literacy Development
38Early 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
39Early 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.
40RELATIONSHIP BETWEEN LANGUAGE KNOWLEDGE AND
LITERACY LEARNING
41Early 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.
42Reading 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
43Writing and Drawing
- Children also need opportunities to learn
writing, drawing, and other composition skills
that involve the use of output tools
44Augmented 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.
45SYMBOLIZATION AND LITERACY LEARNING
!
123
ABCDEFGHIJKLMN
46Graphic 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
47Graphic 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
48The 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
49The 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
50Graphic 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.
51Graphic 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.
52Augmented 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.
53Technology-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
55CHAPTER 14 - EDUCATIONAL INCLUSION OF STUDENTS
WHO USE AAC
56PREPARING 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
57Transition 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
58INVOLVING 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
59THE PARTICIPATION MODEL
- We use the Participation Model as a framework for
making decisions associated with including AAC
users in general educational programs
60Identify Participation Patterns
- Academic Participation
- Competitive
- Active
- Involved
- None
- Social Participation
- Competitive
- Active
- Involved
- None
61Academic 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
62Social 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
63Activity/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.
64Assess 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.
65Assess 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
66Teacher-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
68Assess 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.
70Assisting 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.
