Competence with rational numbers is essential for mathematics proficiency in secondary mathematics. However, many students struggle with rational number concepts, and students with mathematics difficulties struggle even more. The purpose of this study was to examine the effects of an intervention that incorporated the use of explicit instruction…

Multifactorial models of dyslexia have expanded how we consider heterogeneity within the population of children with dyslexia. These models are predicated on the idea that cognitive/linguistic risk factors are not deterministic but instead probabilistic, with the likelihood of difficulties involving an interaction between risk and protective…

The purpose of this review was to update previous reviews on factors related to students' responsiveness to early literacy intervention. The 14 studies in this synthesis used experimental designs, provided small-group or one-on-one reading interventions, and analyzed factors related to responsiveness to those interventions. Participants were…

The present study seeks to evaluate a hybrid model of identification that incorporates response to instruction and intervention (RTI) as one of the key symptoms of reading disability. The 1-year stability of alternative operational definitions of reading disability was examined in a large-scale sample of students who were followed longitudinally…

The intent of this volume was to address the following questions: What is considered acceptable knowledge about learning disabilities? Who decides? Where does knowledge come from? Who uses it and for what purposes? Who benefits? In their article, Artiles et al. (this issue) focus explicitly on the issue of culture and how it has served to impact…

This article describes how a purposeful sample of 62 elementary schools from 17 states implemented a Response to Intervention (RtI) framework for reading. School informants answered surveys and were interviewed about differentiated instruction in Tier 1, screening/benchmarking, where Tier 2 interventions were located, typical group size and the…

The assessment procedures within Response to Intervention (RTI) models have begun to supplant the use of traditional, discrepancy-based frameworks for identifying students with specific learning disabilities (SLD). Many RTI proponents applaud this shift because of perceived shortcomings in utilizing discrepancy as an indicator of SLD. However,…

The policies underlying the specific learning disability (SLD) regulations in the 2004 reauthorization of the Individuals with Disabilities Education Act (IDEA) are analyzed. The analysis focuses on the Response-to-Intervention (RTI) provision ("if the child responds to scientific, research-based intervention") as a diagnostic model,…

The paper presents an intervention framework for the management of communication disorders in learning disabled children. The model is comprised of three components: communicative intentions, presupposition, and the social organization of discourse. Resulting instructional guidelines and principles are offered. (Author/DB)

Responsiveness to intervention (RTI) is being proposed as an alternative model for making decisions about the presence or absence of specific learning disability. We argue that many questions about RTI remain unanswered, and that radical changes in the proposed regulations are not warranted at this time. Since many fundamental issues related to…

Available from: Council for Exceptional Children, 1920 Association Drive, Reston, Virginia 22091. The article describes an "ecological" or "total" model for the assessment of learning disabled children and youth which considers the interaction of all relevant factors, including deficits or strengths within the student, teacher variables, the…

This article examines a 1995 treatment validity model as a framework for identifying learning disabilities. This model: (1) examines both student performance and responsiveness to instruction; (2) delays special education referral until the effects of individual student adaptations in the regular classroom have been explored; and (3) verifies that…

An intervention framework for the management of communication disorders in learning disabled children is presented. The model is comprised of three components: communicative intentions (what a speaker wants to convey), presupposition (a speaker's message in relation to specific information needs of a listener), and the social organization of…

The paper describes and advocates process-oriented rather than product-oriented approaches to language intervention for students with language-learning disabilities. The paper discusses the need for different reasoning strategies in language intervention, a "levels of competence" macromodel for language intervention, a process-oriented micromodel,…

We examined the differential effects of the social cognitive model of sequential skill acquisition (SCM intervention) and the self-regulated strategy development model (SRSD intervention) for writing. One hundred and twenty-one 5th- and 6th-grade Spanish students with learning disabilities (LD) and/or low achievement (LA) were randomly assigned…
