Typical Language/Speech Development (Heward, 2006)
Knowledge of normal language development can help determine whether a child is developing language at a slower-than-normal rate or whether the child shows an abnormal pattern of language development

Speech vs. Language Delays/Disorders
Language-effects formulation of language meaning
Speecheffects physical properties of speech sounds
Delay vs. Disordereffects service delivery

Language Disorders
Language disorders Receptive language disorder Expressive disorder
Communication differences are not disorders Complex mix of issues

Stop and Reflect
True or False? 1. Unclear articulation of speech sounds & an inability to
imitate the speech sounds heard by others indicates a speech impairment.
2. Significant vocabulary gain is representative of a language disorder
3. Reliance on using the word “thing” to refer to words that a child cannot remember may indicate a speech disorder
4. Continuing to express needs with a prevalence of one-or two-word sentences at age 4 is typical of preschool children
![Page 8: Atypical Language Development](https://reader035.fdocuments.in/reader035/viewer/2022081419/568150a9550346895dbebc50/html5/thumbnails/8.jpg)
Stop and Reflect
True or False? 5. All speech and language disorders are biological
6. Young children that stutter often likely have a speech or language impairment.
7. Young children who have difficulty remembering & retrieving words should be evaluated for a delay or disorder.
8. Young children who are unable to use more than 3-4 word sentences by age 4 will need special intervention.

The Development of Speech
Discuss with one another:What patterns of speech did you observe?
![Page 11: Atypical Language Development](https://reader035.fdocuments.in/reader035/viewer/2022081419/568150a9550346895dbebc50/html5/thumbnails/11.jpg)
Assessment of Language and Speech
Clinical AssessmentsNorm-referenced/standardized
Educational AssessmentsDevelopmental/curriculum-based

Case Study:Gabriel
![Page 13: Atypical Language Development](https://reader035.fdocuments.in/reader035/viewer/2022081419/568150a9550346895dbebc50/html5/thumbnails/13.jpg)
Gabe’s Developmental History
Born near expected date but complications with the birthing process
Jaundice Many specialists to rule out issues through 1st yearBabbled, made sounds, etc. ‘on time’Walking came slightly later than usual but still
within expected timeframeAt 2, unintelligibility of speech became more
apparentDiagnosed at about 2 1/2 , but questions remain
(speech and language improves daily too!)

Assessing Gabe
Peabody Picture Vocabulary Test (PPVT): normed and standardized
Peabody Developmental Motor Scales (PDMS)

What is Authentic What is Authentic Assessment?Assessment?
““Authentic assessment refers to the Authentic assessment refers to the systematic recording of developmental systematic recording of developmental
observations overtime about the naturally observations overtime about the naturally occurring behaviors of young occurring behaviors of young
children in daily routines by familiar andchildren in daily routines by familiar andknowledgeable caregivers knowledgeable caregivers
in the child’s life.”in the child’s life.” ((Bagnato & Yeh Ho, 2006) Bagnato & Yeh Ho, 2006)

Assessment, Evaluation, and Planning System (AEPS)
![Page 18: Atypical Language Development](https://reader035.fdocuments.in/reader035/viewer/2022081419/568150a9550346895dbebc50/html5/thumbnails/18.jpg)

Medical Diagnosis vs. Educational Diagnosis
Is there a difference?
Informed clinical judgment
Diagnostic tests
Part C eligibility
Part B eligibility
![Page 20: Atypical Language Development](https://reader035.fdocuments.in/reader035/viewer/2022081419/568150a9550346895dbebc50/html5/thumbnails/20.jpg)
Stop and Reflect
True or False?1.The AEPS is an inauthentic assessment because it
is not standardized
2.Using multiple assessments, and at least one within the context of a child’s daily routines and activities, helps to make more accurate eligibility determinations for speech/language disorders
3.Parents should never be consulted about their children’s speech because they may lie
![Page 21: Atypical Language Development](https://reader035.fdocuments.in/reader035/viewer/2022081419/568150a9550346895dbebc50/html5/thumbnails/21.jpg)
Stop and Reflect
True or False?4. The Peabody Picture Vocabulary Test should never
be used because standardized assessments overestimate eligibility
5. In the state of Ohio, both norm-referenced and curriculum-based assessments must be used to determine eligibility for Part B (preschool) services for language disorders and delays
6. Clinical diagnosis and educational diagnosis are the same thing and allow children to qualify for services in either setting.

Activity
In small groups (elbow partners), discuss the following:Consider what types of possible communication
issues you think Gabriel may haveDiscuss the ways you think an accurate diagnosis
may be brought aboutWho should be involved in making the diagnosis?How might the results of the Peabody Vocabulary test
and that of the AEPS differ? How might they complement one another? What are the implications?
Several ‘partners’ share thoughts with class

Final Thoughts for addressing language delaysin the classroom
Collaboration with team members*Family members/parents as part of the team
Engage multiple strategies*Authentic assessments in
the natural environment improveboth accuracy of assessment and helps teachers and SLPs, evenParents, plan appropriate Instruction/intervention
