This study examined passive genotype-environment correlations (GECs) for language related abilities by comparing environment-child language associations in adoptive and nonadoptive families. Findings indicate genetic mediation of the association between home environmental variables with children's language-related abilities. Implications for…

A teacher and a teacher assistant, working together in an inclusive grade-six classroom, provided an invaluable insider perspective on the kind of context that leads to effective support for all students. Findings from this case study revealed five ways in which the teacher could facilitate the work of the teacher assistant, by: 1) focusing on…

Simulated data were used to demonstrate that groups formed by imposing cut-points based on either discrepancy or low-achievement definitions of learning disabilities (LD) are unstable over time. Similar problems were demonstrated in longitudinal data from the Connecticut Longitudinal Study, where 39% of the children designated as having LD in…

This study examined the use of story-mapping to improve the reading comprehension of six third- and fourth-grade students with specific learning disabilities who exhibited reading deficits. Also of interest was whether the effects would maintain once the intervention was discontinued. Using a descriptive, three-phased, single-subject design, the…

Many students with learning disabilities (LD) exhibit deficiencies in the writing process. In order to achieve an adequate level of writing competence, these students must apply strategies that enable them to effectively plan, organize, write, and revise a written product. Explicit strategy instruction involving a structured style of learning has…

This article presents a checklist that teachers and other education professionals can use when deciding which instructional materials to include in their content area instruction. The checklist addresses several considerations, such as the learners' prior knowledge, vocabulary levels, and motivation. In addition, characteristics of the text…

This article presents a case study indicating that "Herpes simplex" virus (HSV) encephalitis may cause permanent learning disabilities due to damage to the temporal lobes, as it discusses the results of a case study extending over 10 years to determine the long-term effects on both the anatomy of the brain and the intellectual functioning of the…

Through multiple logistic regression modeling, this article explores the relative importance of risk and protective factors associated with learning disabilities (LD). A representative national sample of 6- to 17-year-old students (N = 1,268) was drawn by random stratification and classified by the presence versus absence of LD in reading,…

The reauthorization of IDEA (the Individuals With Disabilities Education Improvement Act of 2004) includes potential use of a response to intervention (RTI) model for the identification of learning disabilities. Using this model, a variety of academic interventions may be implemented with a low-achieving student, with the results monitored to…

Significant limitations in research on learning disability (LD) have included failure to incorporate well-validated guiding theories, use of vague or nonspecific operational definitions, and lack of a systematic framework and common terminology for LD identification. Difficulties in communication among researchers continue to limit theoretical…

In clinical practice, we have come across people with intellectual disability who have gender dysphoria and cross-dress. Here, we review the literature on this subject and present an illustrative case example. We searched databases, followed-up references from relevant articles, and contacted colleagues in the field. We found nine papers with case…

Background: Official guidance on out-of-area placements creates incentives that could lead to people being placed against their own best interests, with negative consequences for them and for the "receiving" authorities. Method: Information was collected for 30 people through interviews with them, their families, home managers and care managers.…

There is a growing concern about the connection between many chemical exposures and learning and other developmental disabilities (LDD). National and local groups are developing new programs around the country that are making this connection--and taking action with regard to policy, education and research efforts. They are working towards reducing…

Difficulties with college algebra can be the gatekeeper for earning a degree. Students struggle with algebra for many reasons. The focus of study was to examine students struggling with entry-level algebra courses and differentiate between those who were identified as having a mathematics disability and those who were not. Variables related to…

The social epistemologist studies the basic nature of knowledge and defines axioms as statements of absolute truths that are undeniable, inescapable, and devoid of most uncertainties (Machan, 1985). The accidental phenomenon of learning disabilities (LD) has pursued the scientific truths in axioms for 42 years. Writing facts and perceptions…
