Indicators and Science Behind Teaching a Student with Dyslexia Dyslexia Professional Awareness Vicki King, M.Ed., CALT, QI Arkansas Department of Education Dyslexia Specialist
The Arkansas State Legislature enacted Act 1294 of 2013, codified as A.C.A. § 6-41-601, Title 6, Subtitle 3, et al., to ensure that children with dyslexia have their needs met by the public school system.

Dyslexia Professional Awareness A.C.A. § 6-41-608 No later than the 2014-2015 school year, the Department of Education shall ensure that each teacher receives professional awareness on 1.The indicators of dyslexia; and 2.The science behind teaching a student who is dyslexic. The professional awareness may be provided: Online; At an education service cooperative; or At another venue approved by the ADE ArkansasIdeas online course: Dyslexia: A Three Part Professional Development (1 hour credit)
A.C.A. § 6-41-601Findings Delayed identification is detrimental to a child’s academic success and self-esteem. Dyslexia can be successfully treated. Early identification and intervention is significantly less than the cost of intensive remediation.
Findings Over 30 years of published research on dyslexia. One of the major sources - National Institute of Health (NIH). Dyslexia represents one of the most common problems affecting children and adults. Dyslexia is the most common and most carefully studied of the learning disabilities, affecting at least 80%of all individuals identified as having a specific learning disability.
National Institute of Health Study NIH tracked 5,000 children from across the country beginning when they were 4 years old until they graduated. They had no way to know which kids would develop reading difficulties. The results of the study were released in 1994.
National Institute of Health Study NIH researchers report that dyslexia impacts 10% of our population. However, some researchers report numbers as high as 17-20%. According to Yale University research, as many as one in five Americans have some degree of dyslexia, although only about 5 percent of children have been formally diagnosed.
The early identification of children at-risk for reading failure coupled with appropriate reading interventions can reduce the percentage of children reading below the basic level in 4 th grade to 6% or less. G. Reid Lyon
It takes 4 times as long to remediate a student with poor reading skills in fourth grade as in late kindergarten or early first grade. NICHD – National Institute of Child Health and Development
A.C.A. § 6-41-602 Definitions Dyslexia Dyslexia Therapist Dyslexia Therapy
A.C.A. § 6-41-602 Definitions Dyslexia is a specific learning disability that is neurological in origin. It is characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities. These difficulties typically result from a deficit in the phonological component of language that is often unexpected in relation to other cognitive abilities.
IDA’s Research Based Definition Dyslexia is a specific learning disability that is neurological in origin. It is characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities. These difficulties typically result from a deficit in the phonological component of language that is often unexpected in relation to other cognitive abilities and the provision of effective classroom instruction. Secondary consequences may include problems in reading comprehension and reduced reading experience that can impede the growth of vocabulary and background knowledge. Adopted by the Board of Directors, International Dyslexia Association: November 2002
Defining dyslexia is a work in progress.
Historical Perspective Word blindness (Kussmaul, 1877; Morgan, 1896) Strephosymbolia (Orton, 1925) Minimal Brain Injury/Perceptual deficits (Strauss, Cruikshank, mid 1900’s) Specific Learning Disability (Kirk, 1963) Specific Developmental Dyslexia (World Neurology Federation, 1968)
Specific Developmental Dyslexia A disorder manifested by difficulty in learning to read despite conventional instruction, adequate intelligence, socio- cultural opportunity. It is dependent upon fundamental cognitive disabilities which are frequently of constitutional in origin. World Federation of Neurology, 1968

“Dyslexia is a specific learning disability” One specific type of learning disability May exist along with other conditions such as ADHD or an oral language disorder
“…neurological in origin” When a person has dyslexia, their brain works or functions differently The functional differences have been shown in fMRI studies There are also size, structural and connectivity differences.
Parieto-temporal (phonology/word analysis) Occipito- temporal (visual/word form) Inferior frontal gyrus (articulation/word analysis) What we know about neural pathways in good readers:
DYSLEXIC LEFT RIGHT Odegard, T.N. et al. (2008). Differentiating the neural response to intervention in children with developmental dyslexia. Annals of Dyslexia, 58, 1-14. TYPICAL
“…characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding.” Word-level reading difficulties are the core reading component of dyslexia. Reflected in difficulty with rapid decoding and encoding and problems recognizing words automatically and fluently. Poor spelling accompanies the reading difficulty.
“…difficulties typically result from a deficit in the phonological component of language…” Phonological awareness reflects a metacognitive understanding that the words we hear and read have a sound-based structure. When a child does not understand the relation between sound and print, word recognition will be delayed.
“…unexpected in relation to other cognitive abilities and the provision of effective classroom instruction” The reading difficulties are not predicted by age, other cognitive abilities, or other academic abilities Effective classroom instruction is important! Monitoring how the student responds to good instruction can lead to earlier intervention.
“…secondary consequences may include problems in reading comprehension and reduced reading experience that can impede growth of vocabulary and background knowledge” When word recognition requires great effort, there are fewer resources for comprehension. If a child struggles to read, that child will read less. A child who reads less learns fewer vocabulary words for reading comprehension.

Key Concepts Dyslexia is a word reading problem Core deficit is phonological processing Primary difficulties Decoding (phonics application) Poor spelling Inadequate instruction and general cognitive deficits are exclusions J. Black, M.D., 2011
Underlying Cause Characteristics Unexpected Relation Coexisting Complications or Assets Phonological Awareness Reading words in isolation Decoding nonsense or unfamiliar words Rate or Accuracy (Fluency) Spelling Reading comprehension Limited vocabulary and background knowledge Other cognitive abilities Language Attention Writing Mathematics Behavior/Emotions Outcomes
What are the primary reading characteristics of dyslexia? Decoding (Nonsense or unfamiliar words) Word Identification (Real words) Fluency Rate Accuracy Spelling
What is the underlying cause of the reading/spelling deficits? Phonological Processing
What is Phonological Processing? Phonological Awareness Phonological Memory Rapid Naming
Phoneme Fundamental or smallest element of speech Single speech sound that can be recognized as being distinct from all other sounds in the language 44 sounds of the English language combine to make the thousands of English words
Phonics Relating speech sounds (phonemes) to alphabet letters (graphemes) Applying knowledge of this relationship to decode (sound out) written words
Phonological/Phonemic Awareness Phonological awareness is the awareness of the sound structure of language. Phonological awareness addresses the larger chunks of language: wordssyllablesonsets/rimes
Phonological/Phonemic Awareness Metacognitive appreciation of the explicit sounds (phonemes) in spoken words Demonstrated by listening and - Blending spoken sounds - Segmenting spoken words into sounds - Manipulating spoken sounds Strongest predictor of word reading success/failure Strong evidence supports the causal link to dyslexia
Phonological Awareness or Phonics?
What is the Alphabetic Principle? Alphabetic understanding: Words are composed of letters that represent sounds. Phonological recoding: Using systematic relationships between letters and phonemes to retrieve the pronunciation of an unknown printed string or to spell words. Regular Word Reading Irregular Word Reading Advanced Word Analysis
What’s the big deal? Successful readers have a well-developed phonological skill. The alphabetic principle of our writing code requires this ability. Therefore, a deficit in phonological awareness is the strongest predictor of reading failure and the underlying cause of dyslexia.
Phonological Memory (Verbal Working Memory) Storing, manipulating, and recalling verbal information Demonstrated by tasks such as repeating a string of digits or repeating multisyllabic nonsense words Difficult to determine unique contribution to dyslexia since phonemic awareness tasks involve some component of working memory.
Rapid Naming Recall of names from long term memory Demonstrated on timed naming tasks Predictive of reading rate or fluent reading of words and text
AR-RAN Record the time it takes a child to read all four rows. Combine the two times and rank by grade level to set district or campus norms.
Are the 3 phonological processing skills equally important in dyslexia identification? Of the three phonological processing skills, phonological awareness is the strongest predictor of difficulty in word reading. Phonological awareness deficits are the causal link to dyslexia

Word Reading Development Reading Comprehension Reading Fluency Word Recognition Decoding Phonological Awareness
What can we do? Recognize early indicators Identify and intervene early Provide appropriate instruction and accommodations
A.C.A. § 6-41-603 Required Screening and Intervention Level 1: Universal Screener Who is screened? ALL K-2 students -This includes transfers from other districts and states Any student in grades 3 -12 experiencing difficulty as noted by a classroom teacher
What is the designated screening tool? The Arkansas Department of Education shall adopt rules to ensure that students will be screened using DIBELS. A.C.A. § 6-41-603 Required Screening and Intervention
What areas are to be assessed? The screening should include: Phonological and phonemic awareness; Sound symbol recognition; Alphabet knowledge; Decoding skills; Rapid naming skills; and Encoding.
If DIBELS Screening indicates the need for intervention, the Response to Intervention (RTI) shall be used to address the needs of the student. If RTI indicates the possibility of dyslexia, the student shall be evaluated. A.C.A. § 6-41-603 Required Screening and Intervention
TIER 1 General Education (Core) Classroom Instruction _________________ All Students Universal Screening / Benchmark Assessments Phonological awareness Sound symbol recognition Alphabet knowledge Decoding skills Rapid naming skills Encoding skills Progress Monitoring TIER 3 Comprehensive Assessment __________________ Intensive Instruction 5-10 % _________________ ID TIER 2 Strategic Instruction (Intervention) 20- 30% __________________ With effective TIER 1 instruction 10 – 15% With effective TIER 2 instruction 5% Tiers of Instruction Timothy N. Odegard PhD, CALP
Level 2: Dyslexia Evaluation Completed by a trained professional using norm-referenced testing; Used to determine if markers of dyslexia are present; Used to determine if therapeutic services are warranted; Used to determine a student’s eligibility for services and accommodations under Section 504. A.C.A. § 6-41-604 Additional Dyslexia Evaluation and Services
A.C.A. § 6-41-605 Instructional Approaches Principles of Instruction: Explicit, direct instruction Systematic, sequential, and cumulative Individualized Comprehensive and inclusive (meaning based) Multisensory Content: Phonology / phonological awareness Sound-symbol association Syllable instruction Morphology Syntax Semantics Strategies for decoding, encoding, word recognition, fluency, and comprehension
Protection Under Section 504 Section 504 covers qualified students with disabilities who attend schools receiving Federal financial assistance. To be protected under Section 504, a student must be determined to: (1) have a physical or mental impairment that substantially limits one or more major life activities; or (2) have a record of such an impairment; or (3) be regarded as having such an impairment. Section 504 requires that school districts provide a free appropriate public education (FAPE) to qualified students in their jurisdictions who have a physical or mental impairment that substantially limits one or more major life activities.
