• Approximately 60 million adults and school-age children in the U.S. have difficulty acquiring reading and spelling skills.

• 1/3rd of fourth grade students • Among minority, inner-city children about 2/3rd (67%) • 25% of adults are unable to read a newspaper• Illiteracy affects all parts of life• (NIH) Illiteracy is a public health issue.••

•≈ 15% drop out of high school

•Number of prison cells

•Reasons for illiteracy:• Instructional and Environmental Reasons (Vellutino

& Scanlon, 2003)

•A. Instructional Reasons:

•Ehri (1989): Inadequate instruction spawning limited reading and spelling development and limited phonological awareness is the primary cause of reading disability

•Blachman, Texas group, Florida Group, . .••••

Page 9: Cognitive component of the Componential Model of … component of the Componential Model of Reading (CMR) in Different Orthographies R. M. Joshi Texas A & M University mjoshi@tamu.edu

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.

•Lyon et al. (1993): 74% of reading disabled in the third grade continue to exhibit reading and spelling problems even at the ninth grade level.

• B. Environmental Reasons:

•Oral language Development (Hart & Risley, 1995)

•Welfare families: 10 million → 500

•Middle class families: 20 million → 700

•Professional families: 30 million → 1100

•Number of books available at home (Chiu & McBride-Chang, 2006)

•Parents reading to children (Feitelson, 1964)

• Enjoyment of reading (Chiu & McBride-Chang, 2006)

•Not only oral language but written language •Seymour et al. examined the speed and accuracy of

familiar word reading and nonword reading in 13 orthographies

•Finnish, German, Spanish, & Greek 95 %

•Portuguese, French, and Danish ≈ 75%

English = 34 % for word and 29% for non-word reading.

Componential Model of Reading

Simple View of Reading

•R = D X C

•If D = 0, then R = 0;

•If C = 0, then also R = 0

•Joshi & Aaron (2000)

•R = D X C + F

•Conclusions•1. Illiteracy is of societal and national concern;

affects all walks of life•2. Decoding (D) and linguistic comprehension (LC)

can explain much of the variance in reading comprehension (RC) while IQ scores predict about 25% of the variance in RC.

•3. Decoding contributes more at the early grade levels and comprehension more at the upper grade levels. Decoding may play an important role in reading comprehension for a more prolonged time in a more opaque orthography. Language comprehension becomes more important for reading comprehension from the beginning to the more advanced stage.

•4. There are qualitative and quantitative differences in decoding and comprehension between hyperlexics (MS) and dyslexics(VN).

•5. Literacy acquisition and literacy problems among bilinguals may be influenced by the type of writing systems and the ‘orthographic distance’ between the two languages.

•6. Considering that the majority of the world’s population is bilinguals, more research studies on bilinguals are needed
