This study used a randomized controlled trial design to investigate the ROOTS curriculum, a 50-lesson kindergarten mathematics intervention. Ten ROOTS-eligible students per classroom (n = 60) were randomly assigned to one of three conditions: a ROOTS five-student group, a ROOTS two-student group, and a no-treatment control group. Two primary…

"UNISON" was an Investing in Innovation (i3) development grant funded by the Office of Innovation and Improvement, U.S. Department of Education to Take Stock in Children (TSIC), a state-wide, 501(c)(3) non-profit, private-public partnership in Florida. UNISON provided a whole school mentoring approach and focused on developing students'…

Community colleges are a large sector of postsecondary education. In 2016-2017, the United States had nearly 1,000 public 2-year postsecondary institutions (community colleges), serving almost nine million students, representing 39% of all undergraduates. The majority of entering community college students require developmental (or remedial) math.…

In contrast to prior federally mandated school reforms, the Every Student Succeeds Act (ESSA) allows states more discretion in reforming their lowest performing schools, removes requirements to disrupt the status quo, and does not allocate substantial additional funds. Using a regression discontinuity design, we evaluate a state turnaround…

The efficacy of a research-based fraction sense intervention for sixth graders with or at risk for mathematics difficulties (N = 52) was examined. The intervention aimed to build understanding of fraction magnitudes on the number line. Key concepts were taught with a narrow range of denominators to develop deep understanding. The intervention was…

The efficacy of a research-based number-sense intervention for low-achieving kindergartners was examined. Children (N = 126) were randomly assigned to 1 of 3 conditions: a number-sense intervention followed by a number-fact practice session, an identical number-sense intervention followed by a number-list practice session, or a business-as-usual…

Although high school graduation rates are rising--the national rate was 82 percent during the 2013/14 school year (U.S. Department of Education, 2015)--dropping out remains a persistent problem in the Midwest and nationally. Many schools now use early warning systems to identify students who are at risk of not graduating, with the goal of…

Two intervention approaches designed to address the multifaceted academic and cognitive difficulties of low-income children who enter pre-K with very low math knowledge were tested in a randomized experiment. Blocking on classroom, children who met screening criteria were assigned to a Math + Attention condition in which the Pre-Kindergarten…

The New York City Leadership Academy represents a unique experiment by a large urban school district to train and develop its own school leaders. Its 14-month Aspiring Principals Program (APP) selects and prepares aspiring principals to lead low-performing schools. This study provides the first systematic evaluation of achievement in APP-staffed…

For the 2013 study, "Transfer Incentives for High-Performing Teachers: Final Results from a Multisite Randomized Experiment," researchers examined the impact of the Talent Transfer Initiative (TTI) on students' reading and mathematics achievement in 10 school districts. The TTI enabled principals of low-performing schools to provide…

The purpose of this study was to investigate the effectiveness of explicit, direct, and generative strategy training and working memory capacity (WMC) on mathematical word problem-solving accuracy in elementary schoolchildren. In this study, children in third grade ("N" = 82) identified as at risk for math difficulties (MD) were randomly…

The Schools to Watch: School Transformation Network Project is a whole school reform model designed to improve the educational practices, experiences, and outcomes of low-performing middle-grades schools. Developed by the National Forum to Accelerate Middle-Grades Reform, the four-year project was funded in 2010 by a U.S. Department of Education…

The authors describe an independent evaluation of the READ 180 Enterprise intervention designed by Scholastic, Inc. Despite widespread use of the program with upper elementary through high school students, there is limited empirical evidence to support its effectiveness. In this randomized controlled trial involving 312 students enrolled in an…

To help improve research-based knowledge of effective instruction for low-literate ESL (English as a second language) learners, the National Center for Education Evaluation and Regional Assistance of ED's (U.S. Department of Education's) Institute of Education Sciences contracted with the American Institutes of Research (AIR) to conduct a Study of…

Students (n = 797) from 36 4th-grade classrooms were taught the control of variables strategy for designing experiments. In the instruct condition, classes were taught in an interactive lecture format. In the manipulate condition, students worked in groups to design and run experiments to determine the effects of four variables. In the both…
