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…

This study assessed the effects of sampling breadth on technical features of word identification fluency (WIF), a tool for screening and monitoring the reading development of first graders. From a potential pool of 704 first-grade students, the authors measured both a representative sample (n = 284) and 2 other subgroups: those with low reading…

During the past decade, responsiveness to intervention (RTI) has become popular among many practitioners as a means of transforming schooling into a multilevel prevention system. Popularity aside, its successful implementation requires ambitious intent, a comprehensive structure, and coordinated service delivery. An effective RTI also depends on…

This study determined the effectiveness of Kindergarten Peer-Assisted Learning Strategies (K-PALS) for students with disabilities. The researchers randomly assigned 89 kindergartners with individualized education programs (IEPs) from 47 classrooms to control (n = 9); K-PALS Level 1 (teachers received 1-day workshop; n = 19); or K-PALS Level 2…

This article introduces a framework for the remediation of number combination (NC) deficits. Research on the remediation of NC deficits is summarized, and research program studies are used to illustrate the 3 approaches to remediation. The Framework comprises a 2-stage system of remediation. The less intensive stage implementing 1 of 3…

This study examined the reliability, validity, and predictive utility of kindergarten screening for risk for math difficulty (MD). Three screening measures, administered in September and May of kindergarten to 196 students, assessed number sense and computational fluency. Conceptual and procedural outcomes were measured at end of first grade, with…

For nearly 10 years, the response-to-intervention (RTI) policy initiative has engendered enthusiasm at federal, state, and local levels and among various stakeholders. Nevertheless, there are basic and important disagreements about its nature and purpose. The authors describe two groups with contrasting perspectives on RTI in an effort to examine…

This study assessed the effects of preventative tutoring on the math problem solving of third-grade students with math and reading difficulties. Students (n = 35) were assigned randomly to continue in their general education math program or to receive secondary preventative tutoring 3 times per week, 30 min per session, for 12 weeks.…

With the last reauthorization of the Individuals With Disabilities Education Act (IDEA) and the Elementary and Secondary Education Act (ESEA, also known as No Child Left Behind or NCLB), special education research exerted a major influence on general education. Even so, the academic outcomes of students with learning disabilities (LD), who are the…

This article presents quality indicators for experimental and quasi-experimental studies for special education. These indicators are intended not only to evaluate the merits of a completed research report or article but also to serve as an organizer of critical issues for consideration in research. We believe these indicators can be used widely,…

This study assessed the effects of Peer-Assisted Learning Strategies (PALS), a reciprocal classwide peer-tutoring strategy, on the reading performance of native Spanish-speaking students with learning disabilities (LD) and their low-, average-, and high-achieving classroom peers. Participants were 132 native Spanish-speaking English language…

First graders (N = 323) participated in an evidence-based classwide reading program (Peer-Assisted Learning Strategies; PALS). A dual-discrepancy approach was used to identify 56 children whose reading performance and growth rates were substantially below those of average readers, indicating they were not responding sufficiently to PALS. This…

This study contrasts the validity of 2 early reading curriculum-based measurement (CBM) measures: word identification fluency and nonsense word fluency. At-risk children (n = 151) were assessed (a) on criterion reading measures in the fall and spring of first grade and (b) on the 2 CBM measures each week for 7 weeks and twice weekly for an…

This article provides an overview of identification of appropriate testing accommodations for students with learning disabilities (LD). First it defines the concept of testing accommodations and review research on test accommodations commonly used with students with LD. Next it examines the validity and fairness in accommodations, as well as the…

A study explored the effectiveness and feasibility of phonological awareness (PA) training with and without beginning decoding components for 25 kindergartners with disabilities in inclusive schools. Students with special needs participating in PA with beginning decoding instruction did better than those just receiving PA and controls. (Contains…
