Analyses were conducted with second graders, drawn from an ongoing multi-cohort randomized controlled trial (RCT), who had been identified for RCT entry based on comorbid reading comprehension and word-problem solving difficulty. To estimate pandemic learning loss, we contrasted fall performance for 3 cohorts: fall of 2019 (pre-pandemic; n = 47),…

The purpose of this study was to explore the efficacy of fractions intervention with and without an embedded self-regulation (SR) component for third-grade students at risk for mathematics disabilities. Fractions intervention focused on magnitude understanding and word problems. Embedded SR was designed to support a growth mindset (fostering…

In this article, the authors summarize results from 5 randomized controlled trials assessing the effects of intervention to improve the fraction performance of fourth-grade students at risk for difficulty in learning about fractions. The authors begin by explaining the importance of competence with fractions and why an instructional focus on…

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 purpose of this set of analyses, conducted on a randomized control trial examining the effects of a fourth-grade fraction intervention, was to assess the initial academic deficit severity hypothesis. With this hypothesis, at-risk students with more severe initial academic deficits are expected to profit less from intervention than do students…

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…

Factors were explored that predicted whether teachers sustained the use of a validated reading intervention. Seventy-three teachers from 37 schools in 3 states were asked in interviews whether they continued to use Kindergarten Peer Assisted Learning Strategies (KPALS) 1 year after their involvement in the program. A logistic regression model was…

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…

This article provides an overview of Peer-Assisted Learning Strategies (PALS) for reading. First, specific activities and research supporting PALS for Grades 2 through 6, High School, Kindergarten, and First Grade are described. Then, research addressing the characteristics of students who have not responded to PALS, as well as approaches to…

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 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.…

The purpose of this study was to determine the proportion of empirical studies published in the last 5 years in a sample of special education peer-reviewed journals that: (1) assessed the effects of reading and math interventions with group designs and; (2) used random assignment to treatment conditions to test those interventions. A hand search…

Proposes a treatment-validity model for the identification of learning disabilities. The four-phase eligibility-assessment process would include evaluating adaptations in the regular classroom and verifying the effectiveness of special education before placement. Considers the technical requirements of this alternative eligibility process, and the…
