AVT Changing Demographics Gallaudet Research Institute (2008) “For the 17-year-olds and the 18year-olds in the deaf and hard of hearing students norming sample, the median Reading Comprehension subtest score corresponds to about a 4.0 grade level for hearing students.” Project Hope Results (1999) Progress Achieved, but Challenges Exist…(Lyons, 2011) Early Hearing Detection and Intervention (EHDI) Act of 2010 reauthorized About half of those referred for a diagnosis following a failed screening are lost to the system (Joint Com. on Infant Hearing sets the “Gold Standard”) One-third of infants in the system do not receive a diagnostic eval. by 3 mos. of age More than half diagnosed are not enrolled in intervention programs by 6 mos. of age Parental Choices Changing Dramatically… In 1995: 40% of families chose spoken language options compared to those who chose sign/visually-based communication modes. In 2005: 85% chose spoken language options compared to 15% who chose sign. (Brown, 2006) Early Intervention Outcomes Data from the Colorado Project are showing that children born with a profound hearing loss who obtain a cochlear implant before they are 2, have a high chance of obtaining intelligible speech (YoshinagoItano, Sedey, Coulter, & Mehl, 1998). This outcome is based on having the cochlear implant mapped appropriately and worn consistently. Direct, repetitive auditory skill instruction as part of an effective early intervention program. Niparko, J., Journal of the American Medical Association (2011) Children receiving cochlear implants before 18 months are achieving age-appropriate spoken language outcomes. “Babies are primed to learn language, but if not exposed to spoken language early, the window begins to close and by 5 years of age, it is substantially shut.” Effects of Early Auditory Experience on Spoken Language at 3 Years (Nicholas & Geers, 2006-Ear & Hearing) Longer use of a cochlear implant in infancy and very early childhood (i.e., before age 3) dramatically affects the amount of spoken language exhibited by 3.5 year old children with profound hearing loss, even more so than a greater amount of pre-implant intervention given to children wearing hearing aids Key factor: early cochlear implantation optimizes spoken language Hierarchy of Listening Skills (Erber, 1977) Detection: ability to respond to presence or absence of sound Discrimination: ability to perceive similarities & differences among 2 or more speech stimuli Identification/Recognition: ability to reproduce a speech stimulus by pointing at a picture, writing, or by repeating the speech heard Comprehension: ability to understand the meaning of speech by answering questions, following directions, paraphrasing or engaging in conversation Detection Awareness of sound…we’re growing the BRAIN, BRAIN, BRAIN!

Children using new cochlear implant technology have provided evidence of accelerated language development after implantation Children who are congenitally deaf might only demonstrate an insignificant delay in language development if they receive their implant early enough The child’s learning capacity and motivation, the implant’s contribution, and the child’s rehabilitation program are all factors that influence the benefit of a cochlear implant Reading, Writing, and Phonological Processing Skills of Adolescents With 10 or More Years of Cochlear Implant Experience (Geers & Hayes, 2010) 112 of the 181 students with cochlear implants from the previous study were assessed again in high school in the areas of reading, spelling, expository writing, and phonological processing 47- 66% performed within or above average range for hearing peers on reading tests Those identified as good readers in elementary were good readers in high school, and the majority maintained their reading levels since elementary compared with hearing peers Written expression and phonological processing were the most problematic areas The high schoolers with cochlear implants performed lower than hearing age-mates in spelling, expository writing, and phonological knowledge Phonological processing skills were a critical predictor of high school literacy skills Reading, Writing, and Phonological Processing Skills, Con’t Conclusions Children who receive cochlear implants as preschoolers, or younger, can frequently achieve age-appropriate literacy skills Significant delays in spelling and written expression compared to hearing peers Development of phonological processing skills is essential for literacy success later on Outcomes of an Auditory-Verbal Therapy Program for Children with Hearing Loss - A Comparative Study with a Matched Group of Children with Normal Hearing (Dornan, Hickson, Murdoch, and Houston, 2007) Results suggested that children in an AVT program would make significant progress in language development and speech production over a nine-month period that would be similar to progress made by typically hearing peers 72.4% of the AVT group fell into the age-appropriate range for total language scores at the post-test High levels of parent involvement and child-directed speech are two desired outcomes of AVT High levels of parent involvement has been suggested to lead to positive language outcomes in children with hearing loss while child directed speech leads to larger vocabularies with faster vocabulary growth The Importance of Vocabulary (Geers and Hayes, 2010) Vocabulary knowledge- formal instruction and exposure leads to a child learning and remembering word meanings The more severe the hearing loss, the larger the delay in vocabulary development (Boothroyd, Geers & Moog, 1991) Vocabulary knowledge is critical for reading comprehension and expository writing Vocabulary development speeds up after a child receives a cochlear implant, especially if implantation occurs during or before preschool age Vocabulary knowledge continuously expands throughout development Implantation early on, combined with improved phonological decoding, assists with reading and compre., leads to literacy skills comparable to hearing peers Receptive Vocabulary (Dornan, Hickson, Murdoch & Houston, 2009) Second stage of a longitudinal study of children in an auditory verbal program included reassessment 21 months after initial assessment Revealed a significant advantage for typically hearing peers in the area of receptive vocabulary, but children in the AV program scored within typical range The typically hearing group had a significantly higher change in PPVT-3 scores than the AV group Typically hearing group: progressed 33.68 months in 21 months AV group: progressed 23.8 months in 21 months The PPVT-3 scores for the AV group were still in average range Acquisition of receptive vocabulary progressed steadily for the AV group 84% achieved age appropriate scores Receptive Vocabulary Cont’d (Dornan, Hickson, Murdoch & Houston) Results measured at 38 months showed similar results to previous assessments There was no significant difference between the mean age equivalent for the AV group and the typically hearing group for receptive vocabulary as measured by the PPVT-3 The typically hearing group showed greater improvement in receptive vocabulary, but 61% of the AV group scored within normal range Vocabulary is one of the biggest predictors of kindergarten success…therefore, early intervention is not about the child, it is about the family learning about vocabulary development. Think of early intervention as “adult education”.

Reading affects the entire report card • Reading is the tide that lifts all the boats of the curriculum (Trelease, 2001) Put Reading First: The Research Building Blocks for Teaching to Read National Reading Panel (NRP) Report in 2000-FREE Copies •Charged with reviewing literature in reading instruction •Reviewed 100,000 studies •Condensed findings into a guide designed for teachers on how to successfully teach children to read based on 5 areas of instruction: Phonemic Awareness Phonics Fluency Vocabulary Text Comprehension Vocabulary • Words we must know to communicate. • Beginning readers have a difficult time reading words that are not part of their oral vocabulary. • The more exposure to oral language children have the more word meanings they will learn. • Most vocabulary is learned indirectly in 3 ways: 1) Engaging daily in oral language. 2) Listening to adults read to them 3) Reading on their own. Phonemic Awareness Ability to notice, think about, and work with the individual sounds of spoken words (understanding that words are made of sounds) Phonemic Awareness instruction will improve a child’s ability to read words, increase reading comprehension, and spelling. Development Activities: *identify and categorize phonemes *blend phonemes to form words *segment words into phonemes *delete, add, substitute phonemes to make new words National Institute for Literacy at ED Pubs PO BOX 1398 Jessup, MD 20794-1398 To download go to the National Institute for Literacy website at www.nifl.gov Reading Outcomes for the Deaf and Hard of Hearing Deaf or hard of hearing 17 and 18- year- old students in a normative sample for research done by Gallaudet Research Institute demonstrated literacy skills that were equivalent to a 4th grade level In a study of 181 elementary students who received a cochlear implant before age 5, over half (52%) had age-appropriate reading scores (Geers, 2006) In high school, 47-66% obtained reading scores at or above average range compared to hearing peers It’s a new generation of children who are deaf/hard of hearing...because it is all about the BRAIN. Hearing loss is not about the ears; it’s about the brain! Hearing aids, FM systems and cochlear implants are not about the ears; they are about the brain! (Flexer, 2008) Critical Keys to a Successful Spoken Language Outcome: *Access the Auditory Centers of the Brain as Early and Completely as Possible; *Then, Practice, Practice, Practice Listening and Talking… *Approach it as a “Neurodevelopmental Emergency” (Flexer, 2008) Parents as Partners The Art of Reading Aloud Single-Most Important Activity Building a Knowledge-Base Required for Reading Success Becoming a Nation of Readers (1985) Commission on Reading funded by U.S. Dept. of Ed. “It is a practice that should continue throughout the grades.” Not only in the home but also in the classroom on a daily basis Reading aloud is more important than work sheets, homework, assessments, book reports, and flash cards.” (Trelease, 2006, p.3) The cheapest, simplest and oldest tools of teaching: the more you read, the better you get. Surprising Findings… • Only 20% of parents read to their children daily • In both poverty and university-level families, fathers read to children only 15% of time while mothers read 76% of time Children are made readers on the laps of their parents.
