Subtyping LD

Have you been hearing a lot about subtypes of LD lately? Perhaps it’s just that I’ve been especially alert to it, but it seems I’ve heard a lot of mentions about subtypes of Learning Disabilities in the last few weeks. I want to write a longer, more thorough discussion of the topic, but I’ve found myself repeating a few foundational comments, so I thought I ought to post them here and let others have a go at them.

First, the idea of subtypes of LD is essentially a given. It has to do with the heterogeneity of LD. Because LD is essentially an umbrella category for a diverse array of learning disabilities (note the plural), there are bound to be subgroups. Some students will have problems primarily with reading, some primarily with arithmetic and mathematics, some with writing, others with combinations of these. That makes for lots of subgroups right there. That is, one could start with dyslexia, dyscalculia, and dysgraphia!

Testing fraud of a different sort

In a puzzling case of a student who appears to have had problems throughout the primary grades and did not get help until fourth grade, Liz Ditz asks the question, How Often Does This Happen? Teacher accused of testing fraud to avoid special education referral for her student. Not until the parents had pushed for years were the child’s problems recognized. Was this a well-meaning, but misguided teacher? Has anti-LD sentiment become so strong that folks cheat to keep kids from having the label?

Fletcher paper about identifying LD

The RTI Action Network published a paper by Jack Fletcher about identification of Learning Disabilities in the context of response to instruction (or intervention; RTI). Professor Fletcher, who has been a leading proponent of RTI since the 1990s, makes a strong case for the importance of examining instruction as a part of determining eligibility for LD services.

Is LD viable?

Panelists for DLD showcase 2010 in Nashville
L-to-R: T. Scruggs (foreground), D. Fuchs, M. Gerber,
and N. Zigmond

At the behest of Rollanda O’Connor, Dan Hallahan gathered four informed people—Naomi Zigmond, Tom Scruggs, Mike Gerber, and Doug Fuchs—to address this question: “The LD Construct: Can it be Saved? Is it Worth Saving?” The discussion, which was held at the annual international convention of the Council for Exceptional Children, as a product of the Division for Learning Disabilities (DLD). Of course, I’m biased (I am compensated as the executive director for DLD), but I have to say that this was a top-notch event.

These advocates agreed that there really is something to LD. They argued clearly and effectively that educators need to reconsider the construct of LD; focus on individual students needs; the needs of those students can (in fact) be discriminated from others who have low achievement; that there’s lots of good to response to instruction (or intervention), but it’s neither likely to address all the learning problems students experience nor identify those who need additional services; and that those students may need instruction that is radically different from what they can get in general education settings.

There’s lots more to what they had to say, and I hope TeachingLD can capture and disseminate it. If so, I’ll relate it here.

More on IQ and reading disabilities

Deficits in reading performance may differ in etiology depending on the IQ of the individuals who have the deficits. According to an article in Behavior Genetics, Professor Sally Wadsworth and colleagues confirmed previous research showing that there is a stronger genetic element in the reading deficits of children with higher IQs (mean = 108.97 ± 6.71) than those with lower IQ (mean = 82.85 ± 6.40). The heritability for the former group is 0.75 ± 0.12, but for the latter it is 0.50 ± 0.10.

Does RtI reduce numbers of children in special education?

In an article slated to appear in Remedial and Special Education, Jeanne Wanzek and Sharon Vaughn reported that widely popular three-tiered approach to addressing did not significantly reduce the number and percentage of students identified for special education across seven elementary schools. Their study, which is limited to the response to instruction or intervention in the primary and early elementary grades and focused primarily on academic intervention, revealed no significant reduction in identification of children as having Learning Disabilities, even though this group would be the most likely to benefit from such prevention efforts. Similarly, there were no differences in the proportion of students identified for special education according to ethnic background.

Too common a concern?

At the Greenwich (CT, US) Time site, Colin Gustafson described a meeting where parents of students with disabilities expressed concern about the special education services their children received from the local schools. Under the headline “Parents voice rage over special education in meeting with Freund, Board of Ed chairman,” Mr. Gustafson reported some of the concerns parents raised and some of the responses from school administrators.

Parents’ frustration with the district’s handling of their children’s special education needs boiled over several times during a meeting with the school board chairman and superintendent Wednesday morning.

Many attendees said the families who strongly advocate for their children — even wage legal battles on their behalf — are too often labeled as “problem parents” and have their concerns dismissed by district administrators.

I wonder how many of these sorts of meetings occur but are not reported in the press. Perhaps some of the parents who read this blog can comment on how common these concerns are.

Read Mr. Gustafson’s report, “Parents voice rage over special education in meeting with Freund, Board of Ed chairman.”

Finding out about a child’s dyslexia

Over on a Psychology Today blog, Robert Langston has a post about recognizing dyslexia early. He’s putting it through the filter of his own personal experience with dyslexia and the filter of a parent discussing a child’s problems with a teacher. Is dyslexia inherited? in the original.

Parents’ and children’s views

The US Public Broadcasting System has two articles that will be of interest to some readers of LD Blog. The titles of them tell enough about the contents, each of which has four subparts, that I can simply list them here:

Flash of the electrons to to Leila over on Special Ed and Me, whose post entitled “Inside the Mind of Someone with a Learning Disability” led me to the articles.

Vouchers and identification rates

Over on the Web site of the Manhattan Institute under the headline, “How Special Ed Vouchers Keep Kids From Being Mislabeled as Disabled,” Marcus Winters and Jay Greene published an article reporting their analysis of Florida’s McKay vouchers program. They report that, schools that have nearby voucher-accepting private schools, the incidence of children identified as having Specific Learning Disability (SLD) is inversely correlated with the number of neighboring private schools.

The question examined in this report is whether special-education voucher programs change the likelihood that students will be diagnosed with an SLD. Voucher programs allow disabled students to attend a private school, which receives payments in the form of full or partial tuition that would have otherwise been directed to the transferring student’s public school. Special-education voucher programs appear to reduce a local public school’s financial incentive to diagnose a marginal student who is merely struggling academically as suffering from an SLD by offering him the chance to leave the public school, enter a private school, and take all of his funding with him.

I hope to get a chance to provide a more detailed analysis of the report. Other tasks require immediate action on my part, though. I’d welcome comments from others who have the time to examine the report.
