Intensive, individualized interventions are certainly the hallmark promise of special education. In a multi-tiered system of supports (MTSS), tier 3 interventions are the most intensive and require individualized delivery to address the learning and behavioral needs of students who are most often identified for special education services. MTSS,…

In this synthesis, we reviewed 65 studies involving elementary students (i.e., grades 1-5) identified with mathematics difficulty (MD) in which authors implemented a mathematics intervention. Of these studies, we identified 33 group designs, 9 quasi-experimental designs, and 23 single-case designs. We aimed to synthesize performance differences…

Word problems require students to read a language-based problem, identify necessary information to answer a prompt, and perform calculation(s) to develop a problem solution. Solving word problems proves particularly challenging for students with mathematics difficulties because skill in reading, interpretation of language, and mathematics are…

Based on the finding that children with mathematical learning difficulties (MLD) have deficits in working memory (WM), the question arises as to whether these children differ from typical learners only in the level or also in the developmental trajectories of WM functioning. To this end, the WM of 80 children with MLD and 71 typical learners was…

The purpose of this pilot study was to explore the impact of mathematics and reading learning difficulties on the mathematics-vocabulary understanding of fifth-grade students. Students (n = 114) completed three measures: mathematics computation, general vocabulary, and mathematics vocabulary. Based on performance on the mathematics computation and…

This article provides a quantitative synthesis of the published literature on word problem solving intervention studies for children with math disabilities (MD). Seven group and eight single-subject design studies met inclusion criteria. Mean effect sizes ("ES"s) for solution accuracy for group design studies were 0.95 (SE = 0.19) for…

We analyzed two nationally representative, longitudinal data sets of U.S. children to identify risk factors for persistent mathematics difficulties (PMD). Results indicated that children from low socioeconomic households are at elevated risk of PMD at 48 and 60 months of age, as are children with cognitive delays, identified developmental delays…

Responsiveness-to-intervention (RTI) is a method for both preventing and helping to identify learning disabilities. An important feature is its multi-tier structure: "primary intervention" (tier 1) refers to classroom instruction; "secondary intervention" (tier 2) usually involves more intensive pullout, small-group…

This study evaluated the psychoeducational patterns of 14 adults (ages 19 to 37) with learning disabilities and reading ability at the fourth-grade level or below. Subjects' backgrounds and reasons for referral are summarized, and results of intervention in oral language, reading, written language, and mathematics are reported. (DB)

A practicum was developed to aid second graders who were experiencing difficulties in reversals and transpositions of letters, words, and numbers in written language and math. At each teacher's recommendation, one or two children demonstrating reversal problems were given help to reduce their reversals. A series of language arts and math tests…

Math difficulties share many common features with reading difficulties. In as much as they do so, the general approach to reading disability overlaps with math disability. Both math and learning to read share several domain-general features such as long-term and short- term memory, successive and simultaneous processing, flexibility in…

This document updates "Accommodations: Assisting Students with Disabilities. A Guide for Educators," published by the Florida Department of Education (FDOE) in 2003. This document is written to assist school district personnel and parents when making decisions about the use of accommodations by students with disabilities in instructional…

Two types of instructional adaptation were explored: routine adaptation (the extent to which teachers establish initial routines to facilitate ongoing adaptation) and specialized adaptation (how teachers modify instructional plans in light of student difficulty). Participants were 110 general educators. (Author/SM)

This article demonstrates procedures for implementing curriculum-based measurement and Gickling's model of curriculum-based assessment concurrently in a comprehensive assessment and intervention system by discussing three case studies. The examples include addressing reading and mathematical difficulties in a general education classroom and…

In order for schools to help students with learning difficulties and disabilities improve their achievement in mathematics, educators, researchers, practitioners, and policymakers need a better understanding of the evidence based on what is behind these students' difficulties in learning math. That is just what they will get with this landmark…
