Basics and Classroom
Accommodations
• Understand the characteristics and causes of
dyslexia
• Understand how dyslexia characteristics are
different in Spanish speaking students
• Understand how to choose accommodations to
benefit individual students
• Review and discuss common accommodations
• (1) Dyslexia means a disorder of
constitutional origin manifested by a
difficulty in learning to read, write, or
spell, despite conventional instruction,
adequate intelligence, and sociocultural
opportunity.
• Dyslexia is a specific learning disability that is
neurological 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. Secondary
consequences may include problems in reading
comprehension and reduced reading experience that
can impede growth of vocabulary and background
knowledge.
Adopted by the IDA Board of Directors, Nov. 12, 2002. This definition is also used
By the National Institute of Child Health and Human Development (NICHD)
• In contrast to the more general term learning
disability
• Problems are at the word level
• More defined in terms of cognitive
characteristics (PA, RAN, Phon. Memory)
• Reading disabilities affect at least 80% of the
LD population – more prevalent type of
learning disability
Region 10 Education Center
• Converging evidence using functional brain
imaging in adult dyslexic readers show a failure
of left hemisphere posterior brain systems to
function properly during reading.

cognitive abilities – Examples
• Ability to learn orally in class: Science, Social
Studies, etc.

Sea of Strengths Model of Dyslexia
Shaywitz, Overcoming Dyslexia, 2003
• The ability to focus on units of sound in spoken
language
• It includes the awareness of sounds of words
(rather than the meanings) in sentences,
awareness of syllables in words, and awareness
of phonemes – or individual sounds – in short
words or syllables.

Decoding
Rapid Naming:
• Effective retrieval of phonological
information from memory
• Has been found as another core
deficit in developmental dyslexia
• Predictive of reading fluency and rate
• Tested on timed tasks

Students who have double
deficits – that is, deficits in both
rapid naming and phonological
awareness – have the most
pronounced reading impairments
and are the most resistant to
intervention.

Orthographic Processing:
• Orthography refers to how spoken words are
represented in written language.
• Orthographic awareness is the ability to perceive
and recall letters, letter strings and words.
• With repeated encounters the reader builds an
orthographic memory (i.e., memory for patterns of
written language) of words so that eventually he or
she instantly recognizes the words without having to
sound them out.

Classroom Management by Nancy Mather and Sam Goldstein.
…Vision problems can interfere with the process of
learning; however, vision problems are not the cause of
primary dyslexia or learning disabilities. Scientific
evidence does not support the efficacy of eye
exercises, behavioral vision therapy, or special tinted
filters or lenses for improving the long-term educational
performance in these complex pediatric neurocognitive
conditions. Diagnostic and treatment approaches that
lack scientific evidence of efficacy, including eye
exercises, behavioral vision therapy, or special tinted
filters or lenses, are not endorsed and should not
be recommended.

Disabilities, American Academy of Ophthalmology, American Association for Pediatric Ophthalmology
and Strabismus, and American Association of Certified Orthoptists
• Although children with dyslexia may make more
oral reading errors than children who are good
readers, the ratio of reversal errors to other
errors is the same.
• Without appropriate reading instruction
children with dyslexia continue to make
decoding errors typical of early readers.

• Letter-sound learning proceeds more rapidly
for children learning to read more transparent
orthographies and more slowly for children
learning to read more opaque orthographies.
(Goswami, 2002; Serrano & Defior, 2008)
• A deficit in phonology is a major cause of
dyslexia in all languages.
(Serrano & Defoir, 2008; Lindsey, Manis, & Bailey, 2003)
• “a Spanish-speaking child with a mild-tomoderate difficulty in phonological awareness
may acquire word reading skills in Spanish with
minimal difficulty, but manifest difficulties in
fluency because of the more transparent
orthography of Spanish relative to other
alphabetic languages such as English.”
(Wagner, Francis, & Morris, 2005, page 8)
• Children who speak Spanish, a more
transparent orthography, with deficits in
phonological/phonemic awareness will more
easily learn the grapheme-phoneme
correspondences.
• The most apparent indication of dyslexia for
native Spanish speakers will be related to the
speed of word reading.
