Characteristics of Dyslexia

Reading / Spelling characteristics are most often associated with difficulties: • Segmenting, blending, and manipulating sounds in words (phonemic

awareness) • Learning the names of letters and their associated sounds • Holding information about sounds and words in memory (phonological

memory) • Rapidly recalling the names of familiar objects, colors, or letters of the

alphabet (rapid naming)

Reading / Spelling Characteristics of Dyslexia: • Difficulty reading words in isolation • Difficulty accurately decoding unfamiliar words • Difficulty with oral reading (slow, inaccurate, or labored) • Difficulty spelling

4

Dyslexia Defined

• Dyslexia is a specific learning disability that is – neurological in origin – 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 – …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 growth of vocabulary and background knowledge

TN 2014 Senate Bill 2002 No., House Bill No. 1735

5

Dyslexia Myths

• Seeing words backwards • A vision problem that an eye doctor can identify or treat • Just reversing letters • Individuals with dyslexia are lazy or unmotivated • Limited to a certain race, gender, social-economic class,

specific languages • It must be identified by a medical professional • You can be cured of Dyslexia • It is rare • Something a person outgrows

Prevalence of Dyslexia

1 in 10 children struggle to read due to dyslexia

Prevalence of Dyslexia It affects at least 80% of the children who manifest a Specific Learning Disability

DEVELOPMENTAL DYSLEXIA

Dyslexia is a brain-based type of learning disability that specifically impairs a person's ability to read. Excerpt from the definition adopted by the National Institute of Child Health and Human Development (2014)

How do we know?

25

Brain Differences Associated with Dyslexia

Functional brain differences are commonly observed in individuals with dyslexia when they perform reading tasks.


Functional Brain Differences:

26

Functional Brain Differences

Individuals with dyslexia present with decreased activation in several brain regions associated with skilled reading.

27

DEVELOPMENTAL DYSLEXIA

Structural brain differences are commonly observed in individuals with dyslexia.

30

Takeaway Points from Brain Research

• There is evidence documenting functional and structural brain differences in children and adults with dyslexia.

• Some differences are likely due to the lack of exposure to reading resulting in developmental delays.

• Some differences are not the result of developmental delays and are rather the result of something else.

Interim Summary

• Word Reading, Reading Fluency and Reading Comprehension are the three major areas of reading achievement

• Additional language skills support the acquisition of reading

• Differences in the development of skills that support reading provides one casual explanation as to why reading falls along a continuum

DYSLEXIA & SPECIFIC LEARNING DISABILITY

RELATIONSHIP BEWTEEN DYSLEXIA AND SPECIFIC LEARNING DISABILITY

49

Relationship of Dyslexia to other terms

“The department of education frequently receives questions from parents and educators regarding dyslexia and its relationship to specific learning disabilities.” TN Department of Education (2016). Understanding Dyslexia: A guide for Tennessee Parents and Teachers.

50

Specific Learning Disability

• .. a disorder in one or more of the basic psychological processes involved in understanding or in using language, spoken or written, which may manifest itself in the imperfect ability to listen, think, speak, read, write, spell, or do mathematical calculations, and that adversely affects a child’s educational performance.

• .. includes conditions such as perceptual disabilities (e.g., visual processing), brain injury that is not caused by an external physical force, minimal brain dysfunction, dyslexia, and developmental aphasia.

• Specific Learning Disability does not include a learning problem that is primarily the result of Visual Impairment; Hearing Impairment; Orthopedic Impairment; Intellectual Disability; Emotional Disturbance; Limited English Proficiency; or, Environmental or Cultural Disadvantage.

(IDEIA Definition 2004; also used by TN Dept. of Education)

65

Guidance from OSERS

“there is nothing in the IDEA that would prohibit the use of the terms dyslexia … in IDEA evaluation, eligibility determinations, or IEP documents.”

Office of Special Education and Rehabilitative Services (OSERS) “Dear Colleagues” letter – Oct. 23, 2015

66

TN 2016 Say Dyslexia

“The ‘Say Dyslexia’ bill addresses the need to identify and intervene appropriately for students with the characteristics of dyslexia but does not identify dyslexia as a separate disability category under Tennessee's special education rules and regulations.”

“Say Dyslexia” Bill (Public Chapter 1058) Additional Information for Districts (TN Dept. of Education)

67

TN 2014 Dyslexia is Real

• “Dyslexia is a specific learning disability that is neurobiological 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.

Who Can Identify Dyslexia?

• School Psychologist can identify all Specific Learning Disabilities

• “Dyslexia is a specific learning disability…”

• Therefore, school psychologists can identify dyslexia

• Do you have a school psychologist in your school?

• Then, you have personnell in your school quaified to identify dyslexia


88

Interim Summary

• Severe Dyslexia is by definition a Specific Learning Disability

• All Specific Learning Disabilities that impact reading are not dyslexia

• Severe forms of Dyslexia are by definition: SLD Word reading, SLD Reading Fluency, or Comorbid SLD Word Reading and SLD Reading Fluency

• School Psychologists are qualified to identify dyslexia

TIER II Some

TIER III Some

ALL students receive research-based, high quality, general education instruction. In general, 80 - 85 percent of students will receive only Tier I instruction.

In ADDITION to Tier I, extra help is provided to students who fall below the 25th percentile in basic math and reading skills. In general, 10-15 percent of students will receive Tier II interventions.

In ADDITION to Tier I, extra help is provided to students who have not made significant progress in Tier II, are 1 ½ - 2 grade levels behind, or are below the 10th percentile in basic math and reading skills. Tier III interventions are more explicit and more intensive than Tier II interventions. In general, only 3 – 5 percent of students will receive III interventions.

Common Features of Effective Tier 3 Interventions for individuals with dyslexia

Direct • Concepts are taught explicitly

Integrated • Letter Knowledge, Phonological Awareness, Decoding, and Spelling are integrated • Morphology instruction is incorporated into word reading and spelling • High frequency words are taught • Word learning informs fluency and comprehension instruction • Vocabulary instruction is integrated into comprehension work Systematic • Built around the structure of the English language and introduces concepts

following a defined scope and sequence

Cumulative • New concepts are introduced and integrated with previously taught concepts

throughout the program (distributed practice)

Addressing the Need

• Does your school have a reading block in place to provide core instruction, enrichment, prevention and intervention?

• Does your school have data systems in place with teams ready to make decisions based on these data?

• Does your school have reading programs in place to address the needs of diverse learners?

• Does your school have the staff with the knowledge needed to implement these programs within an RTI model?
