Two-way dual language (DL) classrooms enroll students of two different language backgrounds and teach curriculum in both languages. I estimate the effect of attending a DL school on student achievement using school choice lotteries from Charlotte-Mecklenburg School District in North Carolina, finding local average treatment effects of 0.04 and…

Summer reading programs are a form of extended school year services for students in special education. However, previous studies have not reported including high percentages of participants in special education, nor have studies sufficiently controlled for selection bias. This study combined propensity score weighting with partially clustered…

In this experimental study, 20 multiple-choice test items from the Massachusetts Grade 5 science test were linguistically simplified, and original and simplified test items were administered to 310 English learners (ELs) and 1,580 non-ELs in four Massachusetts school districts. This study tested the hypothesis that specific linguistic features of…

The UPSTART Summer program is a federally funded i3 validation project that uses a computer-based program to maintain and develop the literacy skills of elementary school students in rural Utah during the summer months when school is out of session. Researchers used a quasi-experimental design to evaluate the impact of the program in forestalling…

Background: The growing interest in principal effectiveness as a means of improving teaching and student learning has led to a focus on the quality of principal preparation programs (PPPs) with calls for the adoption of PPP accountability systems similar to those of teacher preparation programs. Objective: The purpose of the present study is to…

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 evaluated effects of Positive Action (PA), a school-based social-emotional and character development program, on self-esteem levels and processes among minority, low-income, urban youth. A matched-pair, cluster-randomized controlled trial was conducted in 14 Chicago Public Schools with outcomes assessed longitudinally for a cohort of…

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…

This article reports on a study that investigated achievement in math of third and fourth grade dual language immersion (DLI) students, building on research that has demonstrated the academic achievement of students who receive content instruction predominantly in the target language. Our study expands the scope and methodology of prior research…

Though the immediate effect of Reading Recovery (RR) is both strong and well established, the longer term or sustained effect has been less studied and the evidence regarding it has been less conclusive. Michigan Reading Recovery students (n = 328) were compared to control students (n = 264) while in first (2009-2010), third (2011), and fourth…

In August 2010, the Smithsonian Science Education Center (SSEC) received a grant of more than $25 million from the U.S. Department of Education's Investing in Innovation (i3) program for a five-year study to validate its Leadership Assistance for Science Education Reform (LASER) model in three very diverse regions of the United States: rural North…

This experimental study examined the effectiveness of a text-based reading and vocabulary intervention with self-regulatory supports for 4th graders with low reading comprehension. Students with standard scores on the Gates MacGinitie Reading Test between 1.0 standard deviation (SD) and 0.5 SD below the normative sample were included (N=44) and…

Reading is a skill, which is essential for a child's school success. The purpose of this quantitative, causal-comparative study was to investigate the effects of the Reading Recovery (RR) Program. The data utilized were from two groups of students at-risk in the area of reading, first-grade students involved in at least 12 weeks of Reading…
