Schematic chunks denote patterns, schemes, or sophisticated rules and knowledge stored in the long-term memory in the form of chunks. We investigated whether schematic chunking is effective in improving the performance of students with math difficulties (MD) and students at risk of math failure, and how the complexity level of geometry problems…

Systematically observing instruction for students with learning disabilities (LD) provides information regarding the quality of school-based interventions, allocation of instructional time, and other implementation variables associated with student outcomes. In this synthesis, observation studies of reading and mathematics instruction from 2000 to…

The authors report findings from a systematic observational study of middle school educators (Grades 6-8) in two states who provided reading interventions within Tier 2 and Tier 3 of a Response to Intervention (RTI) framework. Intervention sessions were coded and analyzed to understand (a) the frequency and type of evidence-based strategies…

This study investigated the effectiveness of "Solve It!" instruction on students' knowledge of math problem-solving strategies. "Solve It!" is a cognitive strategy intervention designed to improve the math problem solving of middle school students with learning disabilities (LD). Participants included seventh- and eighth-grade…

The purpose of this study was to investigate the effectiveness of explicit, direct, and generative strategy training and working memory capacity (WMC) on mathematical word problem-solving accuracy in elementary schoolchildren. In this study, children in third grade ("N" = 82) identified as at risk for math difficulties (MD) were randomly…

The focus of this article is intervention for third-grade students with serious mathematics deficits at third grade. In third grade, such deficits are clearly established, and identification of mathematics disabilities typically begins. We provide background information on two aspects of mathematical cognition that present major challenges for…

Evaluation of "Concept Diagrams" and a related "Concept Teaching Routine" used in nine secondary school classrooms which included 32 learning-disabled (LD) students, found that teachers successfully selected target concepts and implemented the teaching routine, whereas students (both LD and non-LD) demonstrated gains in concept acquisition,…

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,…

The article outlines specific procedures for analyzing student errors and using the information gained as a tool for making appropriate assessment and instructional decisions. (DLS)

This interview study examined the perceptions and beliefs about cognitive strategy instruction of 31 classroom teachers of underachieving students and 9 strategy researchers. Teachers and researchers generally agreed about components of strategy instruction and when to teach them; one difference was the tendency of researchers to relegate each…

Learning differences or disabilities can be best understood and addressed within the holistic/constructivist theory of knowledge construction and the reciprocal evolution of cognitive structures. Learning differences manifest themselves in the spirals of mental structuring activity that guide relational thinking. Such a perspective focuses on…
