A solid understanding of fractions is the cornerstone for acquiring proficiency with rational numbers and paves the way for learning advanced mathematical concepts, such as algebra. Fraction difficulties limit not only students' educational and vocational opportunities but also their ability to solve everyday problems. Students who exit 6th grade…

To plan cluster-randomized trials with sufficient statistical power to detect intervention effects on student achievement, researchers need multilevel design parameters, including measures of between-classroom and between-school differences and the amounts of variance explained by covariates at the student, classroom, and school level. Previous…

There's a strong case for making social and emotional learning (SEL) skills and competencies a central feature of elementary school. Children who master SEL skills get along better with others, do better in school, and have more successful careers and better mental and physical health as adults. Evidence from the most rigorous studies of…

In this districtwide scale-up, we randomly assigned seventh-grade students within 11 schools to receive a series of writing exercises designed to promote values affirmation. Impacts on cumulative seventh-grade grade point average (GPA) for the district's racial/ethnic minority students who may be subject to stereotype threat are consistent with…

Research Findings: This study investigated how mean classroom-level shyness scores moderated the impacts of "INSIGHTS" into "Children's Temperament" on instructional support and students' math and reading skills in kindergarten and 1st-grade classrooms. "INSIGHTS" is a temperament-based social-emotional learning…

Sixty fourth- and fifth-grade general education teachers were randomly assigned to teach Collaborative Strategic Reading (CSR; Klingner, Vaughn, Boardman, & Swanson, 2012), a set of reading comprehension strategies, or to a business-as-usual comparison group. Results demonstrate that students with learning disabilities (LD) who received CSR…

The current article presents additional analyses of a classwide mathematics intervention, from a previously reported randomized controlled trial, to offer new information about the treatment and to demonstrate the utility of different types of effect sizes. Multilevel modeling was used to examine treatment effects by race, sex, socioeconomic…

To improve the reading comprehension outcomes of children in high-poverty schools, policymakers need to identify reading interventions that show promise of effectiveness at scale. This study evaluated the effectiveness of a low-cost and large-scale summer reading intervention that provided comprehension lessons at the end of the school year and…

In this study, we intend to determine if reading tests aloud provides a differential boost to youth with elevated symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) relative to same-aged peers. Participants were 36 youth, 44% with or at risk for ADHD, who participated in a week long summer camp. Over the course of the week, youth attended…

The Magic Breakfast project provided 106 schools with support and resources to offer a free, universal, before-school breakfast club, including to all Year 2 and Year 6 pupils. The aim of the project was to improve attainment outcomes by increasing the number of children who ate a healthy breakfast. The schools in the project were schools in…

Supporting the reading comprehension and content knowledge acquisition of English language learners (ELs) requires instructional practices that continue beyond developing the foundational skills of reading. In particular, the challenges ELs face highlight the importance of teaching reading comprehension practices in the middle grades through…

Abracadabra (ABRA) is a 20-week online literacy program composed of phonic fluency and comprehension activities based around a series of age-appropriate texts. Four 15-minute sessions per week are delivered by a teaching assistant (TA) to groups of three to five pupils. This report summarizes the findings of a randomized controlled trial assessing…

The ReflectED programme was developed by Rosendale Primary School to improve pupils' metacognition--their ability to think about and manage their own learning. This includes the skills of setting and monitoring goals, assessing progress, and identifying personal strengths and challenges. ReflectED consists of 28, weekly, half-hour lessons, which…

This report examines the impact of content-intensive Professional Development (PD) on teachers' math content knowledge, their instructional practice, and their students' achievement. The study's PD had three components, totaling 93 hours. The core of the PD was "Intel Math," an intensive 80-hour workshop delivered in summer 2013 that…

Improving math achievement among U.S. students remains a high priority as results from recent math assessments continue to show room for improvement. For example, 60 percent of fourth-graders scored below the proficient level on the 2015 National Assessment of Educational Progress. On the most recent Program for International Student Assessment's…
