Brain imaging techniques(since about 1995 )
Example:
Brain activation patterns of literates and illiterates
A special brain area gets activated (fusiform gyrus, occipitotemporal lobe)
3 primary reading areas in the brain:2 for single letters, slow reading1 for automatic reading
All 3 are used simultaneously
The brain becomes “programmed” for automatic reading
Nerve “wiring” develops in children’s brains (“White matter” needed for reading and larger working memory-Nagy et al. 2005)
The occipito-temporal pathway gets activated The brain identifies entire words rather than single
letters Long and short words are read equally fast
(silently) each word or phrase becomes an item Speed rises to 250+ words per minute People can’t help but read Pay attention to message rather than the print
Reading automaticity: (the literacy vaccine!)
Almost an ‘on-off” switch
Only through consistent pairing of sounds and letters
• Textbooks
• Feedback
• Homework
• Class time
• With practice children may pass from the off state to on in 6 weeks
Word superiority effect:we read faster the letters of words we knowbut…People become a fluent readers without knowing the language

And instructional time must be used And instructional time must be used efficiently!efficiently!
We always need lettersWe read by recognizing letters in a row,with known words and context hints handled separately
Letters account for 62% of the adult reading rate Words 16%, context 22%, individual variance 6% The processes are not redundant, they work on different words.
• Like computer technicians fixing problems – letters are generalists Words are not usually recognized as wholes, the visual system
must isolate and recognize the individual letters to get the word
Implications: Methods that get children to read whole words are not efficient If the children read in one language, they can read in another (in
same script).

Visual complexity of characters
Number of characters to automatize…
probably affects the time needed to acquire
automaticity
Amharic
Exact spelling but much larger matrix with some pattern irregularities
More time needed to acquire automaticity, fluency
Kannada – high error ratescomplex forms, multiple visual patterns
Half-consonant combinations and vowel combinations result in a matrix of about 300 characters that must be automatized
Some are unpredicatable
Hebrew voweled (small grains)and unvoweled (large grains)but the letters are separate
Kol benei ha'adam noldu benei xorin veshavim be'erkam uvizxuyoteihem. Kulam xonenu batevuna uvematspun, lefixax xova 'aleihem linhog ish bere'ehu beruax shel axava.
All human beings are born free and equal in dignity and rights. They are endowed with reason and conscience and
should act towards one another in a spirit of brotherhood.
Voweled Arabic – small “grains”Unvoweled Arabic – large “grains”connected letters with rules about connections (and lack thereof)

Egypt: Grade 1 whole-word reading“active learning” class(without vowels children may identify entire words as particular shapes)
Urdu – multiple issues Urdu – multiple difficulties
Few vowel signs even in grade 1
Vowels are not predictable as in Arabic
Dots separated from the main body of letters
Topological imprinting
Need to learn the visual pattern of each word separately
African languages have regular spelling can be automatized in a few monthsFluency to other languages transfers within the same script

Some grade 1 textbooks don’t teach reading!Misguided belief that text interpretation will lead to recognition of letters (Mozambique)
When should students be able to read?
OECD reading study of 16 countriesLatin and Greek scripts
Seymour et al. 2003
Middle-class studentsBest-case scenario
But..the more complex the visual recognition or spelling the longer it takes to automatize
Automatizing large visual patterns (psycholinguistic grains) – takes longer,
• may “trick” some brains students depend more on language knowledge And if they don’t know the language? (English,
French, Portuguese, Urdu) Learning to read in a complex system without
knowing the language is a job for geniuses!
• And if school time is also wasted?
• See test results all over Africa

New monitoring indicator from neurocognitive research
60 words per minute for all• In just about every language and script:
By the end of grade 1 students should “crack the code”
By the end of grade 2 at the latest students should read common words fluently
Students in grade 7 (1st secondary year) should read about 120-150 words per minute and give a summary of what they read
When visual patterns are complex, basic reading needs more time and money
(psycholinguistic grain size theory) English reading takes 2.5 times longer to acquire over
German, Turkish, Spanish (4 months or so needed)
French and Portuguese also take longer. Indian languages – regular spelling, complex scripts
• High error rates in south Indian scripts Arabic – easy with vowels, difficult otherwise
• Perennially slower reading, high error rates Urdu, Persian problematic for the poor
Reading fluently enough to understand?
60 wpm correctly?
Rural Indonesia grade 2 • simple spelling rules, good class time use
Rural Niger – best 6th grader, graduating in 3 weeks• Study only in French, time use uncertain
Oral reading samplesMozambique
A familia do meu melhor amigo Overage student end of grade 3

70 words per minute
Periurban 5th graders - Maputo
Students becoming fluent late may always read slowly
have limited comprehension
• If they finally learn reading in grade 6– They may read 70 wpm in grade 8– They get no more books by grade 8
• They will read little secondary school– university or teacher training colleges– They cannot read fast enough to consult
sources– Or read volumes of text– At 110 words per minute, it takes 5 minutes per page
How to teach complex scripts in 1-2 years to the poor? Lots of practice, build up letter recognition speed - phonics Automatize the common patterns that enable students to read
most material
• Students in English learn the most common words Teach the more rare signs later
• E.g. postpone certain half-consonants of Indian languages (or use “halant”?)
• Keep Arabic, Urdu, Farsi voweled throughout primary school• Keep the Arabic letters on a straight line
Get children practice with feedback! • E.g. read 1 minute a day with every child
Textbooks to take home with much text for all• Not just a few ‘generative words’ to bring from home
Teaching fluent reading to the poor takes more effort child and family characteristics predict initial
reading skills • Though not reading development over time.
High percentage of poor students in a class is often associated with lower student reading performance after accounting for socioeconomic and instructional variables.
How does this happen day to day in class?

Grade-wise time use
Teachers of lower grades spent more time on organization
younger children - higher off-task rates, given a briefer attention span.
Older grades - less reading aloud and drill, increase in lecturing and discussion• Morocco: reading activities 17% of the time in grades
1 and 4, 2.5% in grade 5 (and 15.1% in grade 6, possibly to prepare for exams).
• Brazil: in grade 8 copying time increased because secondary students lack textbooks.

Get results efficiently given time and money
Explicit, systematic instruction for the poor and those who know less• Use software for multiple repetitions that tire teachers
practice to automatize “low-level” processes that the middle class takes for granted• much feedback, extensive practice with books - phonics• Use easily spelled African languages before reading
English• Speed and fluency in basic calculations• Focus investments in grades 1-2 – before the students fall
behind
We need much more and more specific research on various scripts
Some syllabic scripts may not be viable in the long run as currently used and taught
Arabic printing and vowel inclusion – for use by all Some scripts need to be reformed
• Which bodies are responsible in each case?• Eg. South Indian scripts?
Controversies and concerns
Educational philosophy vs. neurocognitive research outcomes
How to disseminate the lines of reasoning?• Philosophical debates – needed but they delay decisions
Reading automaticity sounds too mechanistic to some How to monitor these ‘concrete’ benchmarks and learning
outcomes early on Should the poor be taught differently from the middle class? How to undertake necessary research on memory effects
in classroom?
Alternative measurements
