Blast from the Past: First published December 16, 2015; re-issued September 13, 2017. This explanation of dyslexia seems especially pertinent given the recent documentary from American Public Radio (go to Publications: Audio/Video on this site to listen to that). It elicited a lot of comment at the time and the only thing I would change in it now is the estimate of the phonological/phonemic awareness role in reading problems. There are some more recent data in relatively large studies suggesting a somewhat lower incidence of these problems at least with some populations; that wouldn't change the overall thrust of this much, but it would be, perhaps, more accurate.
Teacher Question:
As I watch the Dyslexia Awareness movement gain momentum and grassroots organizations such as Decoding Dyslexia spur the movement on... I am feeling an increased urgency to take a long hard look at students under my watch that struggle with reading and are eventually diagnosed with a “specific learning disability.” I find myself in agreement that so many public school structures and teacher awareness do NOT include dyslexia. In fact, the term is avoided. I am interested in becoming trained in literacy instruction methods that are geared toward the dyslexic brain and I am looking into Orton-Gillingham training since it is focused specifically on the needs of dyslexics. Why don’t reading professors and reading specialists emphasize dyslexia?
Shanahan response:
In Progress in Understanding Reading: Scientific Foundations and New Frontiers Keith Stanovich supports your conclusion. As for dysteachia, in Early Reading Instruction: What Science Really Tells Us About How to Teach Reading, Diane McGuinness traces reading difficulties back to two sources: our English spelling system and how it is taught. In the introduction to McGuinness's Why Our Children Can't Read and What We Can Do About It: A Scientific Revolution in Reading, Steven Pinker says “Children are wired for sound, but print is an optional accessory that must be painstakingly bolted on. This fact about human nature should be the starting point for any discussion of how to teach our children to read and write." That's why I teach letter sounds but not names.

Tim,
Thank you for mentioning Orton Gillingham. AFTER 16 years as an elementary general and special education teacher with a master's degree in curriculum and instruction and an educational specialist's degree in teaching reading, I discovered OG. It rocked my professional world, and I never looked back. In my experience, OG effectiveness is directly correlated with the therapist's training record. Have you knowledge of research that dis-aggregates OG success rates based on the amount of teacher training in the classic OG model? I have yet to meet the student fo whom a true OG approach failed.

No, no such research has been reported. The one pattern that I have seen is the one mentioned in the post--when OG has not been effective in studies that I have read, the population of students has been especially disabled and it is unclear if anything else would have worked (or if a better trained contingent of OG instructors would have been any more effective).

Dear Shanahan on Literacy - I run a dyslexia therapy center in Iowa, and I am an active member of Decoding Dyslexia. I want to thank you for being so honest in your article, and asking the deep questions that many in literacy have about dyslexia. Especially those who have not been trained in dyslexia, and are just starting to delve into this. I want to take the time to answer some of your questions. Dyslexia can be diagnosed by a Speech-Language Pathologist. At our clinic we give about 6-7 hours of testing, and we look at discrepancies in the child's listening comprehension and oral comprehension versus their reading comprehension. Most of our kids show a large discrepancy. We check phonological wiring using a state of the art test called the CTOPP2. Usually the kids show abnormally low skills in this. Then we use the Woodcock Johnson tests and a few others to measure their reading, writing, spelling and processing speed. From these tests, we can see a well-rounded picture of if the child has dyslexia. They usually have normal intellect, can comprehend what is being said in the classroom, but can not read, write and spell at a level that is indicative of their IQ. This is tell-tale dyslexia. Dr. Orton, who studied stroke victims, saw this same phenomena, and he developed his OG system to address the neurological weaknesses of dyslexia. When science could view the reading brain via fMRI's, it could see that his structured, systematic, multi-sensory approach to teaching the structure of the English language actually changed the wiring in the dyslexic brain and forced it to go to the left side area that is best for reading. These programs do work, because they do address the exact etiology of the disorder. We can see, without a doubt, from birth, that children with dyslexia, have a different brain structure. They have less neural wiring to the left side of the brain, and they have more wiring on the right side of their brain. When learning to read, their brain tries to use centers on the right side of the brain. Science has come to learn that the most efficient areas of the brain to use for reading is the left side. The OG programs force the student to have to start going over to the left side of their brain to read. Given 100-300 hours of OG, the child will build the wiring over to the left side of the brain, and begin to read this way. I get my research from Dr. Nadine Gaab, Dr. Joseph Torgesen, Dr. Stanislaw DeHaene as well as the Shaywitz's, Dr. M. Casanova, and Dr. MaryAnne Wolf. Google any of these researchers, and you can spend 7-8 years reading a plethora of fascinating data. I have two children...one dyslexic, and one not. The dyslexic child had to learn how to read using an OG program. The non-dyslexic one...no...the program was too much detail, an overload, not what she needed. When I tutor dyslexic kids, they may spend 12 months mastering the short vowel sounds and diagraphs (the severe ones). Yes, this is truly a wiring difference in the brain. The disorder does tell us how to teach. It tells us that a multi-sensory, systematic, cumulative and STUDENT-paced program will build the wiring to the most efficient centers in the brain to read. My son wanted to know why some words end in ck (like sock and luck), and others didn't (like junk and dark, and panic). We have 9 different ways to spell the long e sound in the English language (e, ey, y, ee, ea,ei, ie, e-e, and i). Currently our spelling programs try to teach this to kids in a matter of 2-3 weeks in a hodge-podge of methods. A dyslexic kid will spend months trying to sort through the logic and illogicalness of this spelling system.
