Dyslexia, Orthography, and the Componential Model of Reading: Current Research and Classroom Applications R. MALATESHA JOSHI TEXAS A & M UNIVERSITY [email protected] Education Service Center, Region 4 Houston, TX April 1, 2010 • There are known knowns. There are things we know we know (or at least we think we know). We also know there are known unknowns. That is to say, we know there are some things we do not know. But there are also unknown unknowns, the ones we don’t know we don’t know. • Donald Rumsfeld • We have made too many wrong mistakes Yogi Berra • There are known knowns • 33% of fourth grade students are unable to read simple books • 25% of adults are unable to read a newspaper • Illiteracy is a public health issue • >50% of the adolescents with criminal problems and history of substance abuse have reading problems • (NCES, 1999 and Lyon, 2001) • Number of prison cells Number of prison cells “Based on this year's fourth-grade reading Scores, California is already planning the number of new prison cells it will need in the next century.” Paul Schwartz, U. S. DoE, 1998 ≈ 15% drop out of school, over 75% report difficulties in learning to read; only 2% of students receiving special or compensatory education for difficulties learning to read will complete a four-year college program • IDEA • 3 million students are in LD classrooms just because they cannot read • Why is this? • Not because of lack of money (½ a trillion dollars spent per year) • or lack of teachers or their education [45% have degrees beyond bachelor’s degree (I did not add the quality of education)] • How do you solve a problem like literacy? A Poem On Learning Disabilities By Anna Gillingham The college dean says: “Such rawness in a student is a shame– ‘Tis lack of preparation is to blame!” The high school principal says: “Good Heavens, what crudity! The boy’s a fool! The fault of course is in the elementary school.” The elementary school principal says: “Would that from such a dunce I might be spared. They send them up to me so unprepared.” The primary principal says: “Poor kindergarten blockhead! And they call that preparation? Worse than none at all!” The kindergartner says: “Such lack of training did I never see – What sort of a person can the mother be!” The mother says: “You stupid child! But then you’re not to blame. Your father’s family are all the same.” • There are things we know we know (or at least we think we know). • Reasons for illiteracy: • Environmental and Instructional Reasons (Vellutino & Scanlon, 2003) • A. Environmental Reasons: • • • • • Oral language Development (Hart & Risley, 1995) Welfare families: 10 million → 500 Middle class families: 20 million → 700 Professional families: 30 million → 1100 Linguistically “poor” first graders knew 5,000 words; linguistically “rich” knew 20,000 words (Moats, 2001). • Number of books available at home (McBrideChang, 2006) • Parents reading to children (Feitelson, 1964); Enjoyment of reading (McBride-Chang, 2006) “Have you any idea how much that playstation cost?” • We also know there are known unknowns. That is to say, we know there are some things we do not know. • Genetics (Colorado Family Reading study, 1973-) • Gender Differences (McBride-Chang, 2006) • Not only oral language but written language Orthography/Writing system of a language/script Reading level after 1 year of instruction % correct Word reading 100 90 80 70 60 50 40 30 20 10 0 Seymour et al.

(2003), British Journal of Psychology The establishment of an effective sight vocabulary and decoding needs about 2 years of reading experience in English as against 1year in many European languages. • B. Instructional Reasons: • Carroll (1963): High percentage of schoolchildren fail to acquire literacy skills when the classroom instruction is ineffective or insufficient • Calfee (1983): Majority of the reading disability children represent an instructional dysfunction rather than a constitutional disability Poor instruction resulting in poor reading performance is especially true at the early primary grades. • Juel (1988): Children who read poorly at the end of the first grade were likely to remain poor readers at the end of the fourth grade. • Shaywitz et al. (1993): 74% of reading disabled in the third grade continue to exhibit reading and spelling problems even at the ninth grade level. Diagnostic and Statistical Manual of Mental Disorders (DSM-IV, 1994) Reading achievement, as measured by individually administered standardized tests of reading accuracy or comprehension, is substantially below that of expected given the person’s chronological age, measured intelligence, and age appropriate education. Discrepancy Definition Problems with the Current discrepancy definition 1. There is no well-defined difference that indicates significant discrepancy. The extent of discrepancy that is used as a marker for LD (RD) differs among the States and even school systems. Problems with the Current discrepancy definition (Continued) The correlation between IQ and reading achievement is very poor especially at primary grades. IQ is not a potent predictor of reading potential (r =0.5). Stanovich, Cunningham, & Feeman (1984) Grade 1 (ages 6-7) Barnes (1955) Bond & Dykstra (1967) Feshbach, et al.

That is, in addition to the influence of IQ scores on reading ability, reading experience can affect IQ scores. Vocabulary is probably the best single predictor of one’s overall level of intelligence (Sternberg, 1987) Teachers, generally, are not trained to administer IQ tests; psychometricians (diagnosticians) are not trained in teaching of reading. Diagnosis based on IQ scores does not lead to recommendations regarding remediation and instruction. • Study I: First Second Difference Administration Administration (After 3 years) Verbal IQ Performance IQ Full scale IQ Significance 95.20 (9.90) 88.40 (8.60) -6.8 Yes (0.05) 104.20 (12.60) 104.11 (14.10) -0.09 No 99.40 (10.55) 95.26 (10.03) -4.14 Yes (0.05) 110 105 100 95 90 85 80 Performance Verbal 1st 2nd Mean Performance and Verbal IQs of 57 LD children at 2 administrations (approximately at ages 8 and 11) • Study II: (n = 170) First Second Administration Administration (After 6 years) Difference Significance Verbal IQ 90.5 87.4 -3.1 Yes (0.05) PIQ 95.6 93.4 -2.2 No (0.07) FS IQ 91.6 89.9 -1.7 No (0.10) Comp. 84.2 81.7 -2.5 No (0.07) WR 77.6 77.0 -0.6 No spelling 77.6 74.0 -3.6 Yes (0.05) Bentum (2000) Reading Achievement Scores over a Period of 3 years (n=237) Reading Word Spelling comprehn recogn _______________________________________ Pretest (1998) 87.5 78.2 78.3 Post-test (2001) 85.2 77.3 76.3 • But there are also unknown unknowns, the ones we don’t know we don’t know. • If you come to a fork in the road, take it.

WORD RECOGNITION PHON. AWARENESS DECODING (and SPELLING) SIGHT RECOGNITION Reading is a multifaceted skill, gradually acquired over years of instruction and practice. Components of Reading • Word Recognition – identification and pronunciation of words (Decoding). – Sight Vocabulary (Instant word recognition) – (both speed and accuracy are important) • Comprehension – Listening and reading are processes which are combined to produce comprehension and, in a sense, understanding. (Vocabulary is a subcomponent of comprehension.) • Componential Model of Reading (based on Simple View of Reading) • Componential Model of Reading • Simple View of Reading • R = D X C (Gough & Tunmer ; Hoover & Gough) • If D = 0, then R = 0; if C = 0, then also R = 0 Evidence for the two-component nature of reading • Experimental Psychology: Frederiksen (1982); Jackson & McClelland (1979); Palmer et al.

Key elements of decoding instruction include the following: 1. Phonological awareness training, especially in phonemic awareness. 2. Instant letter-recognition training 3. Introduction of sound-symbol correspondences 4. Introduction of the six orthographic types of syllables 5. Introduction of common syllable-division patterns 6. Introduction of morphemes – prefixes, suffixes, roots 7. Training in recognizing and understanding word origins 8. Teaching of a procedure for learning to read irregular words 9.

Children with dyslexia can be helped by using colored lenses/colored overlays. Children with dyslexia have problems in decoding and spelling but not in listening comprehension. Dyslexics tend to have lower IQ scores than non-dyslexics. Most teachers receive intensive training to work with dyslexia children.

It is theoretically not valid; it does not give directions for remedial instruction. Matthew Effect in Reading Matthew 25:29: For unto everyone that hath shall be given and he shall have in abundance, but from him that hath not shall be taken away even that which he hath. Keith Stanovich: The Matthew Effect: “The rich get richer and the poor get poorer.” • likes reading • good comprehension • good decoding • Reads! • good phonemic awareness • poor phonemic awareness • poor decoding • poor comprehension • dislikes reading • Doesn’t read!

Poor This unfortunate situation is particularly tragic since well-established procedures are available from diverse disciplines. •Explicit instruction in reading makes a difference in learner outcomes, especially for low-achieving students •Early identification and intervention (preventing reading difficulties as early as possible) is more effective than later identification and intervention. • Componential Model can be applied to different languages; however the contribution of decoding and comprehension may be different in different languages. • Probably instruction in decoding strategies may be completed early in Spanish while it may be prolonged in Chinese. • Comprehension strategies (including vocabulary) could be taught from early grade levels. • COMPONENTIAL MODEL PROVIDES AN ALTERNATE MODEL FOR ASSESSMENT AND INTERVENTION, WHICH IS EASY, TEACHERFRIENDLY, AND PRAGMATIC • There is a need for increased preparation of preservice teachers to teach the linguistic components of the English language. • Teacher training programs must explicitly teach the interdependence of these components in effective reading instruction. • Textbooks used in pre-service reading education courses should be carefully selected to include all components of scientifically-based reading research.

Two or three words with these phonograms are taught. Children are asked to say the words and copy them. During next session, these words are tested for spelling Move to Decodable texts (Scholastic) • Strategy training • 1. Children (in small groups) recall the strategies • 2. They scan the text for difficult words Instructor goes over these words and builds schema • 3.Instructor models the strategies during every lesson. • 4. Children take turn and read incorporating the strategies • 5. They summarize in one or two sentences without looking at the book Comprehension training: Strategy instruction • The 7 strategies: 1. Purpose of reading 2. Schema activation 3. Stop and think 4. Make use of visuals 5. Raise hand for help 6. What I know so far 7. Summarize • Berkeley, Bender, Peaster, and Saunders (2009) reviewed the development and implementation of RTI in 50 states and concluded that because of the lack of specificity in assessment and intervention, RTI “seems to hold a similar trajectory as the discrepancy model” (p. 94). • Wagner (2008): “Although identification models based on response to instruction appear potentially promising, the notion that they represent real progress for identification and intervention for children with dyslexia should be considered to be a popular myth until evidence from rigorous evaluation is available” (p. 188). • Componential Model can be applied to different languages; however the contribution of decoding and comprehension may be different in different languages. • Probably instruction in decoding strategies may be completed early in Spanish while it may be prolonged in Chinese. • Comprehension strategies (including vocabulary) could be taught from early grade levels. • 1. Literacy acquisition and literacy problems among bilinguals may be influenced by the type of writing systems. • 2. Among bilinguals with reading problems, whether they exhibit reading problems in one or both the languages may depend on the ‘orthographic distance’ of two languages. If the two orthographies are similar, such as Spanish and Italian, then reading problems might occur in both the languages. On the other hand, if two orthographies are farther apart, such as English and Japanese, it is possible to exhibit reading problem in only one language. • 3.
