Analysis of consistent Zearn Math users and a comparable group of non-users in District of Columbia Public Schools (DCPS) shows that students who used Zearn Math consistently had higher levels of academic growth than similar students with low- or no-usage. This analysis used two quasi-experimental methods, Coarsened Exact Matching (CEM) and fixed…

This report analyzes evidence from a new study assessing the effectiveness of Quantway 1 (QW1), a single-term accelerated developmental math course with a focus on quantitative reasoning. Quantway® is one of the Pathways courses (along with Statway®) developed by a network of faculty and content experts convened by the Carnegie Foundation to…

We published our first set of Connections Academy efficacy reports containing independently assured efficacy statements in 2018. We went on to build on that body of research, and updated our reporting with new findings in 2021. Our latest study compared Connections Academy students' state test scores in reading and math with students in…

We used a comparative interrupted time series design to examine the impact of the Massachusetts' Wraparound Zone Initiative on student achievement, attendance, retention, and suspension. This initiative was designed to create coordinated district systems that allow schools to proactively and systematically address students' nonacademic needs. The…

This systematic review of research on early childhood programs seeks to identify effective approaches capable of improving literacy and language outcomes for preschoolers. It applies consistent standards to determine the strength of evidence supporting a variety of approaches, which fell into two main categories: "comprehensive…

The 6-yr degree-completion rate of undergraduate science, technology, engineering, and mathematics (STEM) majors at U.S. colleges and universities is less than 40%. Persistence among women and underrepresented minorities (URMs), including African-American, Latino/a, Native American, and Pacific Islander students, is even more troubling, as these…

Background. The state of Iowa has seen a drastic increase in the number of schools that provide one laptop for each student. These 1:1 schools have invested large amounts of time and money into becoming a 1:1 school. The current research on 1:1 schools is sparse, and policy makers are actively trying to evaluate those programs. Purpose. To…

Four-week summer academy programs served homeless children and adults in two contiguous innovative learning programs. The programs may be the first of their kind in the homeless literature in which both adults and children were exposed to career, academic, and leadership opportunities in the supportive learning environment of a university campus,…

Nationwide, close to 40 million adults lack a high school diploma or a General Educational Development (GED) credential. About a quarter of high school freshmen do not graduate in four years, and while many high school dropouts eventually do attend GED preparation classes, too few ever pass the GED exam or go on to college. Students with only a…

This is the fourth-year report in a five-year evaluation of the Milwaukee Parental Choice Program (MPCP). This report features analyses of student achievement growth three years after the authors carefully assembled longitudinal study panels of MPCP and Milwaukee Public Schools (MPS) students in 2006-07. The general purposes of the evaluation are…

This study explores the effects of a Two-Way Bilingual Immersion (TWBI) program on language majority and minority students. The fundamental hypothesis was that the process of receiving instruction in two languages (English and Spanish) throughout elementary school (i.e., attendance at a TWBI school) would help the native Spanish-speaking students…

The purpose of the quantitative research study was to determine if participation in the Health Sciences and Technology Academy (HSTA) led to significant differences in the math and reading/language arts scores on the West Virginia Educational Standards Test 2 (WESTEST 2), between students who participated in the program compared to students who…

In this set of four supplemental tables, the authors compare the baseline test scores of the treatment and matched control group samples observed in each year after KIPP entry (outcome years 1 to 4). As discussed in Chapter III, the authors used an iterative propensity score estimation procedure to calculate each student's probability of entering…

The present quantitative study evaluated the effects of Supplemental Educational Services (SES), a federally mandated component of No Child Left Behind, on student achievement in reading and mathematics. SES provides free tutoring outside of school to disadvantaged students who attend Title I schools in their third year of failing to achieve…

In 2002, voters in Florida approved a constitutional amendment limiting class sizes in public schools to 18 students in the elementary grades, 22 students in middle grades, and 25 in high school grades. Analyzing statewide achievement data for school districts from 2004-2006 and for schools in 2007, this study purports to find that "mandated…
