3 University of Florida EARS Project: Early Auditory Reading Success Significance Federal and State of Florida initiatives to improve early reading performance of children in public schools Putting Reading First (9/10/06) Reading First part of No Child Left Behind Research evidence Importance of phonologic (phonemic) awareness and auditory skills stressed by National Reading Panel ( and National Institute of Children s s Health and Human Development (NICDH)
4 EARS Program Rationale: Five Component Skills of Reading Phonemic Awareness (sound/speech sound skills) Phonics (phoneme/grapheme skills) Fluency Vocabulary Comprehension
5 Multiple Tiers of Reading Instruction Models: Conventional (e.g., Torgesen, 2005) Approach vs. Early Intervention (EARS) Reading Skills EARS Program Core Reading Program Powerful Intensive Intervention ( Struggling Readers ) APD? Pre-K K Grade
6 Definition of Auditory Processing Disorders: 2000 Consensus Conference on APD Journal of American Academy of Audiology 11: : Nov Definition: APD is broadly defined as a deficit in the processing of information that is specific to the auditory modality. Levels of auditory processing, e.g., Detection of sound (threshold or hearing sensitivity) Discrimination of basic properties of sound Frequency Intensity Duration/temporal properties Speech (word) recognition Complex speech processing Speech sound discrimination Dichotic listening Speech perception in background noise or competing message
7 Technical Report of ASHA Working Group on (Central) Auditory Processing Disorders (2005) Definition of (C ) AP Broad definition the efficiency and effectiveness by which the CNS utilizes auditory information Narrow definition the perceptual processing of auditory information in the CNS and the neurobiological activity that underlies that processing and gives rise to electrophysiologic auditory potentials.
8 Screening for Auditory Processing Disorders (APD) in Kindergarten Children: Research Questions What combination of auditory measures (pure tone audiometry, tympanometry,, and otoacoustic emissions) is most efficient for hearing screening of kindergarten children? Can the outcome of screening for auditory processing disorders contribute to detection of children at risk for reading failure? Is intensive intervention for children with auditory, language, and reading readiness deficits effective in preventing reading failure?
9 EARS: Hearing & Auditory Processing Screening Screening Peripheral Hearing Image from the American Academy of Audiology
10 EARS: Hearing & Auditory Processing Screening New ASHA guidelines for audiologic screening of children ages birth to 5 include consideration of otoacoustic emissions (OAEs( OAEs) ) among other specific procedures and protocols (Diefendorf( Diefendorf,, 2005) No published investigations of screening for auditory function in kindergarten children (<( 5 years old) Auditory function in first grade children (>( 6 years old) is described by Lyons, et al. (2004) in DPOAEs in children at school entry: A comparison with pure- tone screening and tympanometry results. (N = 1003 children) When the results of a test protocol which incorporates both DPOAEs and tympanometry were used in comparison with the gold standard of pure tone screening plus tympanometry,, test performance was enhanced. The use of a protocol that includes both DPOAEs and tympanometry holds promise as a useful tool in hearing screening of schoolchildren, including difficult-to to-test test children (p. 702).

21 Early Auditory Reading Success (EARS): Pilot Project in One Elementary School (03-04) Children diagnosed with hearing, cognitive, attention, or other deficits referred for appropriate management Intervention components FM systems in each kindergarten classroom All kindergarten students complete Earobics Multi-sensory reading instruction strategies used by each kindergarten teacher Children diagnosed with APD and/or deficits in phonologic awareness receive intensive small group treatment by speech pathologist letter recognition phonologic awareness other basic reading skills
22 Title I Elementary Schools: Noisy Learning Environments Circa 1955 Modular classroom design AC Unit
23 Early Auditory Reading Success (EARS): Small Group or Individual Intensive Instruction (sequential during school year) Phonologic awareness (approximate time = 3 to 5 minutes) Rhyme recognition, generation, matching Phoneme detection Blending at different levels (word, syllable, onset, phoneme) Segmenting Deletion (elision) Vowel discrimination Based partially on LiPS program Alphabetic understanding (approximate time = 5 to 6 minutes) Writing (approximate time = 3 to 4 minutes) Spelling (approximate time = 7 to 8 minutes) Reading (approximate time = 6 to 7 minutes) introduce and review sight words Read decodable book
24 Literacy Outcome Measure: DIBELS (Dynamic Indicator of Early Literacy Skills) Developed at the University of Oregon ( Required by Alachua County School System to monitor academic progress in kindergarten children Four measures of reading reading skills Initial sounds fluency (ISF) Letter naming fluency (LNF) Phonemic segmentation fluency (PSF) Nonsense word fluency (NSF) Administered four times in kindergarten year Early fall semester (September) Late fall semester (December) Early spring semester (January) Late spring semester (May)

46 Screening for Auditory Processing Disorders (APD) in Kindergarten Children: Conclusions Tympanometry and DPOAEs,, in combination, offer an efficient strategy for hearing screening of kindergarten children. The results of auditory processing can be used to determine children at risk for reading and academic failure. Intensive intervention for auditory processing and phonologic awareness deficits improves early literacy skills conclusion based on analysis of short-term term outcome (DIBELS scores at end of kindergarten year).
47 EARS: Five Components 1. All kindergarten children are screened for hearing sensitivity and auditory processing 2. Soundfield amplification systems are installed in all kindergarten classrooms 3. All kindergarten children complete Earobics computer based program for developing auditory pre-reading reading skills 4. Classroom teachers receive in-service training on phonological awareness and auditory skills, which they focus on for 15 minutes daily with students in small groups 5. Children with abnormal performance on the Staggered Spondaic Words test (SSW) receive intensive one-on on-one one or small group instruction on auditory and pre-reading reading skills
48 EARS: Screening Screenings are conducted during the first part of the academic year y for: Auditory status Peripheral hearing Auditory processing Language and Reading Readiness (optional) Early Reading Screening Inventory (ERSI) (Lombardino,, et al., 1999) Well accepted measure of reading readiness found to correlate highly with results of auditory processing screening Dynamic Indicators of Basic Early Literacy Skills (DIBEL Measure of reading readiness given at four intervals to all kindergarten children in the state of Florida
