In 2010, the Institute of Education Sciences commissioned a much-needed national evaluation of response to intervention (RTI). The evaluators defined their task very narrowly, asking "Does the use of universal screening, including a cut-point for designating students for more intensive Tier 2 and Tier 3 interventions, increase children's…

The purpose of this analysis was to examine achievement gaps on fractions for very-low-performing students as a function of whether they receive inclusive fraction instruction or specialized fraction intervention and with the shift to Common Core State Standards (CCSS). In three randomized control trials conducted in 3 consecutive years, 203…

The primary purpose of this study was to assess the effects of strategic counting instruction, with and without deliberate practice with those counting strategies, on number combination (NC) skill among students with mathematics difficulties (MD). Students (n = 150) were stratified on MD status (i.e., MD alone versus MD with reading difficulty)…

The purpose of this study was to assess the effects of schema-broadening instruction (SBI) on second graders' word-problem-solving skills and their ability to represent the structure of word problems using algebraic equations. Teachers (n = 18) were randomly assigned to conventional word-problem instruction or SBI word-problem instruction, which…

The purposes of this study were to assess the efficacy of remedial tutoring for 3rd graders with mathematics difficulty, to investigate whether tutoring is differentially efficacious depending on students' math difficulty status (mathematics difficulty alone vs. mathematics plus reading difficulty), to explore transfer from number combination (NC)…

This experimental study examined the influence of a classwide peer-tutoring reading program (Peer-Assisted Learning Strategies; PALS) on the quality of social relationships of elementary school children. Using a sociometric procedure, social preference and friendships were evaluated before and after the PALS program. Overall (mean) and…

An evaluation of empirical evidence from three studies published in journal articles and a book chapter indicated insufficient cause to view the Adaptive Learning Environments Model as a successful, large-scale, full-time mainstreaming program for integrating handicapped pupils and remedial/compensatory education students into general education.…

Special education is under fire from within and without. Full inclusionists and detracking advocates want to abolish all "separatist" special education settings and "unjust" disability categories, tests, and placements; politicians and school administrators deplore special education's high costs. However, mainstreaming efficacy…

A small-group mathematical problem-solving tutorial treatment with explicit instruction including transfer to novel problems was evaluated with 40 students. On word problems and transfer word problems, tutoring effected reliably stronger growth, although effects on real-world problem solving, while moderate to large, were not statistically…
