Phonological Awareness and Literacy DevelopmentBuilding block of literacy (National Reading Panel,
2000; Gillon, 2000)
Predictor of future reading success (Wagner, Torgesen, and Rashotte 1994)
Greater improvement in reading abilities with phonological awareness training (Hatcher, Hulme, and Ellis 1994)
Phonological Awareness and Language Hansen (2003) and Megli (2004):
10-week small group phonological awareness training program
20-minute intervals, twice a week Activities included syllable blending &
segmenting, rhyme recognition & production, phoneme recognition, etc.
Significant gains in expressive & receptive language skills were demonstrated
Dyke (2008): Replicated intervention methods used in
Hansen (2003) and Megli (2004) studies. Measured only auditory comprehension Significant gains in auditory comprehension
of typically developing preschoolers
See-the-Sound Visual Phonics (Visual Phonics)
Multisensory strategy that represents all of the sounds of English with a hand-shape cue and corresponding written symbol
Hand and symbol cue for each sound
Provides visual, tactile, & kinesthetic information about phonemes
Not a communication system, but rather an instructional tool
Visual Phonics and Phonological Awareness
Narr (2008) examined the relationship of phonological awareness and decoding skills in 10 students who were deaf or hard-of- hearing.
• Visual Phonics was incorporated during the phonemic awareness and phonic aspects of the reading process.
• Participants were able to use phonological information to make rhyme judgments and to decode
Visual Phonics and Language ImpairmentDyke (2009)
• 25 preschool children with speech and/or language deficits
• 2 experimental groups (PA only; PA + VP; 1 control group
• 10 week small group phonological awareness intervention
• Activities included rhyme production & recognition, syllable segmenting & blending, & beginning sound awareness.
• Results: Auditory comprehension, expressive language, language content and language structure improved significantly in both experimental groups, but not in the control group.
Visual Phonics and LiteracyGergits (2010)
• 25 preschool children with speech and/or language delay
• 2 experimental groups (PA only; PA + VP); 1 control group
• 10 week small group phonological awareness intervention
• Activities included rhyme production & recognition, syllable segmenting & blending, & beginning sound awareness.
• Results: No significant difference between groups in literacy skill acquisition. Trend toward more gains in PA + VP group.
Research Questions1. After a six month lapse, to what extent do speech-language impaired preschoolers maintain gains in language and literacy from treatment with phonological awareness?
2. After a six month lapse, to what extent do speech-language impaired preschoolers maintain gains in language and literacy from treatment with phonological awareness supplemented by visual phonics?
3. After a six month lapse, is there a difference noted between the phonological awareness intervention vs. the phonological awareness intervention supplemented by visual phonics upon language and literacy abilities?
Subjects10 of the 25 subjects were available
Speech and/or language delay based on results of the Clinical Evaluation of Language Fundamentals-Preschool, 2nd Edition (CELF-P:2) and Goldman Fristoe Test of Articulation, 2nd Edition (GFTA-2)
No significant academic concerns
Normal hearing and visual acuity
Students of two central Illinois at-risk early childhood programs

MethodologyPrevious studies utilized pretest-posttest control group design. Current study utilized a time series design.
The following language and literacy tests were administered approximately 6 months after completion of the previous study:
• Test of Auditory Comprehension of Language, 3rd Edition
• Clinical Evaluation of Language Fundamentals – Preschool, 2nd Edition
• Phonological Awareness and Literacy Screening –Pre-Kindergarten
• Phonological Awareness and Literacy Screening-Kindergarten
Testing conducted by 1 licensed SLP or 1 of 2 supervised undergraduate students in CDS
Data AnalysisCELF-P:2 core language scores and TACL-3 quotient
scores were used to compare the overall change in language abilities and receptive language of the experimental and control groups.
PALS total percentage correct scores were used to compare the overall change in literacy abilities of the experimental and control groups.
Performance was evaluated using descriptive statistics and inspection of tabled data.

Summary of ResultsSubjects made substantial gains in language abilities following
10 weeks of PA or PA + VP intervention. Six months later, language gains attained at PT1 were not retained.
Subjects made greater gains in early literacy skills following 10 weeks of PA + VP intervention only. Subjects in this group continued to make greater gains over the next 6 months, as well. Subjects in the other groups made gains; however, they were not as large.
Clinical ImplicationsChildren with speech-language deficits did not retain language gains realized following 10 weeks of PA or PA + VP intervention.• 10 week intervention not adequate amount of time for
lasting language changes.
• Children in VP + PA group relied on hand shape cues, but did not develop an internal representation of the sounds.
Children with speech-language deficits improved early literacy skills after 10 weeks of PA + VP intervention, and continued to see gains 6 months later. Children who received PA intervention without VP did not make as large gains. • VP may have more impact on early literacy skills than
language skills.
• Changes may be realized over time rather than immediately.
Clinical Implications
Speech-language pathologists should play an active role in phonological awareness intervention.
Consider the timing, duration, and intensity of intervention.
Strengths and Limitations
A control group was incorporated to determine if changes in core language, receptive language, and early literacy skill development could be attributed to the interventions.
Only a small number of participants from the previous study were available for testing, potentially compromising the reliability of these results.
Amount of PA intervention incorporated into subjects’ preschool curricula was not controlled and may have influenced measurements.
Future Research
Further exploration of the use of VP to develop language and literacy skills in a speech- language impaired population.
• Longer intervention time periods
• Study subject with language impairment without speech involvement
• Extend intervention into the classroom and/or home
