Method<br />

Participants<br />

Five high school students, all from <str<strong>on</strong>g>the</str<strong>on</strong>g> same<br />

special educati<strong>on</strong> program, participated in<br />

this study. These students were between 15<br />

<strong>and</strong> 19 years of age. Each had been identified<br />

with moderate cognitive disabilities. Categories<br />

of cognitive disability were established in<br />

compliance with <str<strong>on</strong>g>the</str<strong>on</strong>g> criteria stated in <str<strong>on</strong>g>the</str<strong>on</strong>g> Individuals<br />

with Disabilities Educati<strong>on</strong>s Act (P.L.<br />

105–117). Licensed psychologists <strong>and</strong> students’<br />

eligibility teams had determined <str<strong>on</strong>g>the</str<strong>on</strong>g><br />

students’ classificati<strong>on</strong> via appropriate measures<br />

of general intellectual functi<strong>on</strong>ing <strong>and</strong><br />

adaptive behavior. Each participant primarily<br />

used oral speech as his or her primary communicati<strong>on</strong><br />

mode, but all participants also c<strong>on</strong>sistently<br />

used AAC systems to augment speech<br />

<strong>and</strong> language use at school. These AAC supports<br />

included c<strong>on</strong>sistent use of pers<strong>on</strong>al <strong>and</strong> classroom<br />

visual strategies or aids such as visual<br />

schedules, visual behavior programs, social stories,<br />

communicati<strong>on</strong> boards, sentence completi<strong>on</strong><br />

aids, <strong>and</strong> classroom rules <strong>and</strong> instructi<strong>on</strong>s<br />

(Downing, 1999; Gray & Gar<strong>and</strong>, 1993; Hodgd<strong>on</strong>,<br />

1995). Special educati<strong>on</strong> teachers <strong>and</strong>/or<br />

general educati<strong>on</strong> classroom pers<strong>on</strong>nel identified<br />

participants as having difficulty using appropriate<br />

pragmatic-social communicati<strong>on</strong> skills in<br />

social educati<strong>on</strong> settings. All participants had at<br />

least <strong>on</strong>e Individualized Educati<strong>on</strong> Program<br />

(IEP) goal that suggested deficits in social <strong>and</strong><br />

pragmatic language skills. See Table 1 for participant<br />

344 / Educati<strong>on</strong> <strong>and</strong> Training in Developmental Disabilities-September 2008<br />

Bob. Bob was a 17-year-old male diagnosed<br />

with Fragile-X syndrome. His primary mode of<br />

communicati<strong>on</strong> with peers <strong>and</strong> teaching staff<br />

was oral speech. His verbal communicati<strong>on</strong><br />

was augmented with pictorial representati<strong>on</strong>s<br />

of items or ideas (i.e., visual strategies) in <str<strong>on</strong>g>the</str<strong>on</strong>g><br />

classroom as needed. Bob appeared to have<br />

adequate functi<strong>on</strong>al vocabulary <strong>and</strong> sentence<br />

structure in structured classroom routines. He<br />

initiated <strong>and</strong> resp<strong>on</strong>ded to communicati<strong>on</strong>,<br />

although approximately 80% of his communicati<strong>on</strong><br />

c<strong>on</strong>sisted of resp<strong>on</strong>ses. Bob participated<br />

in structured academic activities <strong>and</strong><br />

frequently took his communicati<strong>on</strong> turns in<br />

<str<strong>on</strong>g>the</str<strong>on</strong>g>se structured educati<strong>on</strong>al settings.<br />

Occasi<strong>on</strong>ally, breakdowns in communicati<strong>on</strong><br />

exchanges were observed when Bob was<br />

in group/classroom situati<strong>on</strong>s. For example,<br />

when he verbally resp<strong>on</strong>ded to questi<strong>on</strong>s from<br />

teaching staff, he often did not make eye c<strong>on</strong>tact,<br />

turned his body away from his communicati<strong>on</strong><br />

partner, <strong>and</strong> used an inappropriately<br />

high pitch <strong>and</strong> sarcastic t<strong>on</strong>e of voice. During<br />

<str<strong>on</strong>g>the</str<strong>on</strong>g>se times, his sentence length also became<br />

notably reduced. Bob’s Speech-Language Pathologist<br />

(SLP) had instituted a visual prompting<br />

AAC system that c<strong>on</strong>sisted of pictorial<br />

prompts with printed words for each academic<br />

less<strong>on</strong> that functi<strong>on</strong>ed as a sentence<br />

completi<strong>on</strong> strip. The purpose of this system<br />

was to facilitate l<strong>on</strong>ger verbal utterances, but<br />

Bob did not use it without verbal reminders<br />

from teaching staff. Therefore, Bob’s sp<strong>on</strong>taneous<br />

communicati<strong>on</strong> interacti<strong>on</strong>s were often<br />

limited to <strong>on</strong>e- or two-word phrases <strong>and</strong> two
