Dysgraphia, Dyslexia, and OWL LD Are Diagnoses That Have Treatment Implications Educational Paradox: For the most part assessment and treatment are divorced for academic skills in that professionals specialize in one but not the other. Teachers teach. Psychologists assess. :. Teaching is often not tailored to assessment of the individual student or differential diagnosis of the LDs. In contrast, in the fields of medicine, mental health, physical and occupational therapy, and speech and language assessment and treatment of the individual are entrusted to the same professional who develops conceptual models for linking them.

PAL II Working Memory Model for Reading and Writing Assessment and Instruction For dysgraphia, orthographic coding and sequential hand movements the orthographic loop--are critical.
For dyslexia, focus on 3 word forms, phonological loop, and executive functions. PAL II Working Memory Assessment-Instruction Model
For OWL LD, focus on syntactic and morphological awareness and word finding strategies + all working memory components. PALII Working Memory Assessment-Instruction Model
Tier 3: Dyslexia Can Be Differentiated from Other Specific Learning Disabilities Affecting Written Language Scientifically supported diagnosis is as important as scientifically supported instruction. 3 Research-Supported Specific Written Language Disabilities: Dysgraphia, Dyslexia, Oral and Written Language Learning Disability (OWL LD) Require scientifically supported assessment and diagnosis by qualified psychologists and speech and language specialists. Behavioral expression can vary across development. May have common and unique genetic and neurological bases; effective treatment shares some common instructional components but also requires unique instructional components.

Dysgraphia Problem in handwriting automaticityretrieving and producing legible letters effortlessly and fast, Problem in spelling with or without indicators of dyslexia, Problem in finger motor planning, and/or Problems in executive functions for self-regulating the composing process (fluency and quality). Note: Handwriting problems may not show IQ-achievement discrepancy but spelling and composing do. Typically those with dysgraphia do not qualify for occupational therapy services. Those who do have severe motor problems have handwriting problems for other reasons and also require treatment specialized for specific motor problems.
phonological Phonological & ORTHOGRAPHIC LOOP and Executive Functions in Working Memory morphological ORTHOGRAPHIC Teach Phonological and Working Memory Skills Explicitly Specialized Instruction for Dysgraphia
Instruction for Dysgraphia Teach plan for letter formation (study numbered component strokes in model letter form) -- overcomes sequential finger movement problem. Cover letter and hold letter form in working memory for increasing duration (photographic leprechaun). Write letter from memory and compare to model. Revise if necessary.
Instruction for Dysgraphia Only practice each of 26 letters once in session writers warm-up (avoid habituation, all letters equal opportunity to become automatic). Always name letter at each stage (study, cover, see in minds eye in memory, write from memory, and compare to model)facilitates retrieval fluency. Always teach for transferfollow letter writing practice with composing on a teacher-provided prompt and share writing with peers (communication of ideas).
Instruction for Dysgraphia Teach for Letter Retrieval from long-term memory (Writing letters that come after and before other letterstransfers to longer compositions). Teach self-monitoring and other-monitoring of letter legibility (recognizable out of word context) in written compositions.
Instruction for Dysgraphia Monitor progressassess automatic letter writing (first 15 seconds), total letter legibility, and letter writing speed (total time). Teach letter writingdo not just use keyboards as accommodation. Research is showing that in K to 6 writing by pen results in longer texts, faster writing, and more idea expression than writing by keyboard. Teach keyboarding explicitly before expecting students to use word processor for writing assignments.
Developmental Model 1.Teach Integrated Letter Form Writing and Letter Form Naming: Big Strokes for Little Folks (by Rubell, Therapy Skill Builders) introduces letters by common strokes and includes activities for developing motor control in forming legible letters. Goal: Legibility (others can recognize) and Accurate letter formation. 2.Teach automatic letter form writing (direct retrieval and production). PAL Lesson Set 3 or Handwriting Lessons. 3.Teach fluent retrieval of letter forms during composing. 4.Teach self-monitoring of letter writing.
Orthographic Lessons (Looking Games) PAL Guides 1998 (pp. 192) Show written word (on chalk board, overhead, or written list at students desk) from the reading or spelling curriculum briefly (about 1 second) with this instruction while sweeping finger under the word in left to right direction: Look carefully at each letter in this word. Then cover the word with a card and ask the children to spell the word or write a designated letter or letter group (orally taking turns or everyone writing independently). Then uncover the word and play one of the games on the next slide.
Orthographic Lessons (Looking Games) PAL Guides 1998 (pp. 192) 1. Direct children to look carefully at this written word: breakfast 2.Cover word for about 1 second. 3.3a. Whole Word Game: Now spell what you saw (do not name the wordso children have to rely on memory for all the letters in the word). breakfast 4.3b. Letter in a Word Game: Now name (or write) the first letter in the word (then the last letter). b, t 5.3c. Letter Groups/Clusters in a Word Game: Now name (or write) the first two letters (br), the last two letters (st), and the third and fourth letters (ea).
PAL 1998b Handwriting Lessons Instructions: Study the numbered arrow cues in ____(name letter). Cover ____(name letter). (Start with 1 sec delay between covering and writing letter and increase.) Now write_____(name letter). Compare_____(name letter) to the model letter. If your ____(name letter) looks different from the model letter, fix it so it looks the same. Instructional Adaptation: Ask children to name letters as they write them.
Alphabet Retrieval Game for Improving Automatic Retrieval PAL Guides (pp. 193)* Name or Write the letter that comes after these letters: a, s, w, g, m. Name or Write the letter that comes before these letters: u, r, t, l, i. 24 sets of five after and five before items to use in the context of a writing lesson aimed at all levels of language. *also in the PAL II User Guide.
Instruction for Dysgraphia Teach manuscript letters first. If children become automatic in manuscript proceed to cursive. Research showed no advantage for cursive writing for at- risk 1 st graders. Manuscript writing has greater transfer from writing to reading and from reading to writing (especially in word processing environment). Introduce cursive writing. If too difficult (e.g. child has dysgraphia) focus on becoming a reader of cursive rather than writer of cursive. Let children choose preferred writing format and teach and practice that until automatic. Research showed that good writers choose a mix of manuscript and cursive or manuscript only. In Australia children can choose their preferred writing format more choose manuscript.
Response to Instruction Letter Writing (by hand) PAL II Alphabet Writing*: Print the letters of the alphabet in order as accurately and quickly as you can without making a mistake. Use manuscript not cursive writing. PAL II Copy A*: Copy sentence with all the letters in the alphabet from a model (no memory requirements). PAL II Copy B: Copy paragraphsustain handwriting over time in three 30 second intervals. Scores: *Automatic legible letter writing (first 15 seconds) Legible letter writing. Legible letter writing speed (total time)
Dyslexia Problems in accuracy and rate of oral reading of words and text and pseudowords and/or spelling Skills above discrepant from Verbal Comprehension Index (Verbal IQ) and below population mean. Language (except for phonology) is a relative strength that can mask severe problems in working memory that are invisible without assessment. Processing deficits in orthographic, phonological, RAN, and executive functions (Inhibition and RAS). Writing as well as reading disability because spelling problems, which tend to persist beyond the reading problems, shown to be linked to written composition. Reading problems may resolve in elementary grades but writing problems persist and these students need explicit instruction in writing and reading-writing integration K -12 (and not just accommodations).

Abbott & Berninger, 1999; Carlisle & Rice, 2004) PAL Lesson Sets 12 and 15 for phonological, orthographic, and morphological awareness, decoding words of Latinate and Greek as well as Anglo Saxon origin, reading fluency, and reading comprehension. 4 th Grade Carlisle (1996) Reasoning with Reading (Vocabulary Meaning, Sentence Interpretation, and Paragraph Understanding). Educators Publishing Service, Cambridge, MA.
Response to Instruction Assess: accuracy and rate of oral reading of pseudowords (PAL II, TOWRE, KTEA-2) accuracy and rate of oral reading of real words on lists (WIAT II, PAL II Morphological Decoding, TOWRE, KTEA-2) or passages (GORT-4 accuracy, rate, fluency) spelling real words (WIAT II Spelling, PAL II Word Choice) and pseudowords (WJ III Spell Sounds)
Response to Instruction Assess for working memory components: accuracy (WIAT II items 4 to 29) and rate of letter naming (RANsingle letters and letter groups, that is phonological loop), awareness of phonological word form and its parts (PAL II rhyming, syllable, phoneme, and rime), orthographic word form and its parts (PAL II receptive and expressive orthographic coding), and morphological word form and its parts (PAL II Does it fit? Are they related? Finding the fixes), and executive function (Rapid Alternating Switching, RAS).
OWL LD Who are the children who are low in oral reading and spelling but do not show IQ achievement discrepancy? Extremely impaired in morphological and syntactic awareness and often word retrieval Also impaired in all the working memory components that children with dyslexia are Fast responders to phonics but persisting real word reading and reading comprehension problems
Oral Language + Written Language Disability (OWL LD) Problems in decoding, reading words, oral reading fluency, and/or reading comprehension Problems in writing (spelling + syntax) Typically no IQ-achievement discrepancy based on Full Scale (or Verbal IQ) But substantial oral language problems in phonological, morphological, and syntactic awareness and often word retrieval that require treatment. Struggle in learning oral language and then in using oral language to (a) learn from teacher talk and (b) learn written language.
