This randomized controlled trial examined the efficacy of an elementary school service-learning program, Connect Science (CS), on classroom practices and students' science achievement, civic engagement, and social skills. Fourth grade teachers were enrolled into intervention versus control conditions resulting in 41 classrooms (20 intervention)…

This study tests the influence of a video-based, analysis-of-practice professional development (PD) program on upper-elementary teachers' science content knowledge, pedagogical content knowledge, and teaching practice and on their students' achievement. Using a cluster-randomized experimental design, the study compares the outcomes for teachers in…

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…

We examined the effects of a professional development (PD) system designed to support teachers' use of data-based instruction (DBI) to improve early writing outcomes for children with intensive needs. The PD system, called DBI-TLC, provided "tools" for early writing assessment and intervention, "learning modules" including…

This study examined the impact of a commonly adopted elementary universal social-emotional learning program, Second Step, on student social-emotional and academic outcomes following 2 years of implementation. The cluster-randomized wait-list control trial included 61 schools, 321 teachers, and 8,941 early elementary students across 2 states, with…

Culturally and linguistically diverse learners with and without learning disabilities enrolled in public schools are tasked with learning content, a new culture, and a new language. Meeting their language and literacy needs requires systematic use of evidence-based practices and deep knowledge of culturally and linguistically responsive practices…

Research shows that some elementary math curricula are more effective than others at increasing student achievement. Most studies in this research base typically included teachers and classrooms that differ, so the results represent "average" curriculum effects, which raises an important question: Are curricula that are effective on…

This project tested the effects of adding instruction of trios of children in patterning, mathematics, early literacy, or social studies to ongoing instruction in kindergartens. Children were randomly assigned to trios which were randomly assigned to one of four kinds of instruction. A quarter of the trios received patterning instruction with a…

Students with writing difficulties may have difficulty when writing informational text with source material due to (a) inexperience with such text and (b) difficulties reading and understanding source material. Teaching students to take notes related to informational text using text structures (e.g., description, compare/contrast) may help them…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program designed to develop upper-elementary students' vocabulary skills in order to improve reading comprehension. The study used a true, group-randomized, experimental design, which randomly assigned 46 4th grade classrooms (n=1324 students) from 12 districts…

In this study, we used a quasi-experimental, longitudinal design to examine the English language arts (ELA) and mathematics test scores of emergent bilinguals (EBs) in DLBE 50:50 models versus English as a second language (ESL) models in Indiana over four academic school years. With a focus on the midwestern U.S., we bring attention to a…

This study assesses the long-term linguistic and academic outcomes associated with different bilingual language education models for low-income dual language learners (DLLs) residing in a bilingual, bicultural context. As part of the Miami School Readiness Project (MSRP), we analyzed the impact of program model on gains in English language…

This brief is directed to researchers and adds to the research base about instructional practices that are related to student achievement. Additional evidence on these relationships can suggest specific hypotheses for the future study of such instructional practices, which, in turn, will provide research evidence that could inform professional…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program designed to develop upper-elementary students' vocabulary skills in order to improve reading comprehension. The study used a true, group-randomized, experimental design, which randomly assigned 46 4th grade classrooms (n=1324 students) from 12 districts…

Class-wide interventions have strong empirical support for improving behavior in general education classes but are rarely tested in special education classes. The present study examined the effects of the Class-wide Function-related Intervention Team (CW-FIT) program, a group contingency intervention, on the on-task behavior of six elementary…
