  5. How can you remember:

  6. Learning Disabilities • Samuel Kirk, 1962 “…A retardation, disorder or delayed development in one or more of the processes of speech, language, reading, writing, arithmetic, or other school subjects resulting from a psychological handicap caused by possible cerebral dysfunction and/or emotional or behavioral disturbances. It is not the result of mental retardation, sensory deprivation, or cultural and instructional factors.”

  7. Specific Learning Disabilities Act of 1969 • Disorder in basic psychological processes • Spoken and written language • Manifested in specific disorders • Listening, thinking, talking, reading, writing, spelling, or arithmetic • Included were perceptual handicaps, brain injury minimal brain dysfunction, dyslexia, developmental aphasia • Not included were learning problems attributed to: • Visual, hearing, or motor handicaps • Mental retardation, emotional disturbances • Environmental disadvantage

  8. IDEA (101-476) I • Specific learning disability • Disorder in one or more of the basic psychological processes involved in • Understanding or using language, spoken or written • May manifest in an imperfect ability to • LISTEN • SPEAK • READ • WRITE • SPELL • MATHEMATICAL CALCULATIONS

  9. IDEA (101-476) II • The term learning disability includes • Perceptual handicaps • Brain injury • Minimal brain dysfunction • Dyslexia • Developmental aphasia • The term learning disability does not include learning difficulties resulting primarily from • Visual, hearing, or motor handicaps • Mental retardation or emotional disturbance • Environmental, cultural, or economic disadvantage (U.S. Office of Education, 1977, p. 65083)

  10. LD Definition, continued*** • Basic psychological processes means ability to interpret information received through : • auditory means (oral) • Visual means (sight) • Kinesthetic means (motor) • Tactile means (touch) • ….and to communicate information through these channels.

  11. Severe Discrepancy • Discrepancy between student’s academic performance and his or her estimated or assumed ability or potential • Based on assumption of overall average to above average IQ • A discrepancy of two or more years below expected performance levels in one academic area • Parameters not specified nor authorized by federal definition

  12. LD - strengths & weaknesses 120 1 v 85 P M R 7 70 ACHIEVEMENT APTITUDE (IQ)

  13. Controversial Definitions • National Joint Committee on Learning Disabilities, 1981 • Heterogeneous groups • Concomitant handicapping conditions • Learning Disabilities Association of America, 1986 • Chronic condition of neurological origin varying in manifestation and degree • Affecting self-esteem, education, vocation, socialization, and/or daily living activities

  14. SLD Definitions - changes

  15. History of the Field Learning Disabilities • Four phases • Foundation (1800-1930) • Transition (1930-1960) • Integration (1960-1980) • Current (1980-present)

  16. Foundation Phase1800-1930 • Emphasis on brain research • Hinshelwood-“word blindness”, brain defect • Goldstein- behavioral and perceptual impairments resulting from brain damage • Strauss & Werner- Wayne County Training School • Mental retardation attributed to brain damage rather than genetic factors • Characteristics suggested need for instructional tactics

  17. Transition Phase1930-1960 • Emphasis on clinical study, assessment, and remediation strategies • Orton- cerebral dominance, dyslexia • Fernald- remedial programs • VAKT- multisensory approach to learning • Kephart- perceptual motor theory of learning • Frostig- visual perceptual skills • Developmental Test of Visual Perception

  18. Integration Phase(1960-1980) • Established disability area in US schools • Samuel Kirk- popularized term learning disabilities • Specific Learning Disabilities Act of 1969 • Education for All Handicapped Children Act of 1975,PL 94-142- forerunner to IDEA • Bill of Rights for children with disabilities • Formation of The Council for Learning Disabilities

  19. Current Phase(1980- present) • Turbulent transitions and challenges • Movement for full inclusion • Culturally and linguistically diverse learners • Computer technology, issues and trends • Impact of attention deficit disorder research • Controversy over assessment and the use of the severe discrepancy criteria for placement

  20. Prevalence • 2.8 million pupils ages 6-21 • Largest category of special education, slightly less than 50% of all individuals receiving service • Dramatic increase since the 1970’s • Possible reasons • Ambiguous parameters • Increase public awareness • Improved diagnostic and assessment capabilities • High social acceptance of the label

  21. Etiology I (CAUSES) • Acquired trauma • Injury to the central nervous system • Prenatal- smoking, drugs, alcohol • Perinatal- anoxia, low birth weight, prematurity, difficult delivery, forcep trauma • Postnatal- high fever, stroke, concussion, TBI

  22. Etiology II • Genetic/Hereditary Influences • Familiality studies are not conclusive • Suggest speech, reading, and language difficulties may occur in certain families but cannot eliminate the influence of environmental reasons • Heritability studies compare twins • Certain types of learning problems are more common among identical twins than fraternal twins

  23. Etiology III • Biochemical abnormalities • Fiengold theory- proposed that allergic reaction to food products contributed to hyperactive behavior; not substantiated within the scientific community • Cott’s megavitamin theory- learning disability resulting from vitamin deficiency; not substantiated by scientific community

  24. Etiology IV • Environmental possibilities • Contributing to brain development • Low socioeconomic status • Malnutrition • Lack of access to health care • Quality of instruction • Poor teachers and inadequate instruction • Lack of direct systematic instruction

  25. Characteristics (Lerner, 2000) • Disorders of attention • Poor motor abilities • Psychological process deficits • Information/processing problems ** • Oral language difficulties • Reading and written language difficulties • Quantitative disorders • Social skill deficits

  26. INFORMATION PROCESSING

  27. Information Processing Problems* • Visual processing • Visual discrimination “d” “b” “p”, “m” “w’” • Visual sequencing “135” “153” • Visual tracking (follow a line) • Visual figure-ground (foreground/background) • Visual spatial abilities (aligning lines in space) • Visual memory (retaining what was just seen) • Visual motor integration (control movements to match what your eyes see)

  28. Information Processing, cont • Auditory processing • Auditory discrimination (ability to tell one sound from another “d” from “t” • Auditory sequencing (sounds in order – aminals • Auditory closure (ability to blend sounds) • Auditory figure/ground (tune in to relevant, tune out background noise) • Auditory memory (retain what is heard)

  29. Learning Disabilities – Have you seen this child? • Reading • Mathematics • Written language • Spoken language • Short term memory • Working memory • Metacognition • Attributions

  30. Disability in Reading • Reading comprehension • Cannot recall facts, sequences, or main themes • Word recognition errors • Omissions, insertions, substitutions, reversals • Oral reading • Insecurity, loses place • Word analysis skills • Phonological awareness difficulties, dyslexia

  31. Disability Area Mathematics • Computation skills • Word problems • Spatial relationships • Writing or copying shapes • Telling time • Understanding fractions/decimals • Measuring

  32. Disability in Written Language • Spelling • Omission or substitution of letters • Auditory memory and discrimination difficulties • Handwriting • Absence of fine motor skills • Lack of understanding of spatial relationships • Composition • Sentence structure • Paragraph organization • Complexity of stories

  33. Disability in Memory • Short-term memory • Recalling in correct order, of either aurally or visually presented information shortly after hearing or seeing the items • Working memory • Retaining information while simultaneously engaging in another cognitive activity • Success in reading and math depend on this ability • Crucial for word recognition and reading comprehension

  34. Disability in Spoken Language • Oral Expression • Word choice • Understanding complex sentence structures • Responding to questions • Mechanical deficits • Syntax, semantics, phonology • Pragmatics • Conversational skills • Nonverbal language

  35. Disability in Metacognition • Lack of awareness of strategies and resources needed to perform effectively • Inability to monitor, evaluate, and adjust performance to ensure successful task completion

  36. Disability in Attributions • Students may attribute success to situations beyond their control such as luck rather than to their own efforts • Chronic failure makes success seem unattainable • Learned helplessness (Seligman,1992) • Passive learners • Deficits in strategic learning behaviors

  37. Situational Problems • Social and Emotional • Lower self-esteem, poor self-concept, social imperceptiveness, and peer rejection • Attention and Hyperactivity • Difficulty staying on task, completing assignments, and following directions

  38. Assessment • Norm-referenced • Criterion-referenced • Curriculum based • Portfolio

  39. Figure 6.5 Educational Placements of Students with Learning Disabilities

  40. Instructional Approaches • Cognitive Training • Self Instruction: Talk it through • Mnemonic Strategies: HOMES • Direct Instruction: Teacher-led • Skill training • Task analysis • Learning Strategies: How to learn new info • Strategies Intervention Model (SIM) • 1. Find best way to get, store, and use info • 2. Teacher alters how info is presented*** • 3. Social skills, expressing oneself directly taught • ***GRAPHIC ORGANIZERS***

  41. Learning Strategies -- Sequencing of solving 52 divided by 4*** • Visual/Verbal: Write out in detail how to do each step; color code • Visual/Nonverbal: Draw a series of boxes, each with a bit of information in order • Tactile/Kinesthetic: Make a 3X5 card for each step; put in order • Auditory/Verbal: Write out steps in detail and read out loud; have someone tape record steps, and listen, self talk
