A quasi-experimental design in six kindergarten classrooms (n = 123 students) was used to study the effects of the KinderTEK iPad-based math program on the math achievement of students in general education classrooms. Student math outcomes in three treatment ("early start") classrooms were compared to math outcomes for students in three…

Background. Placement in developmental education in college is associated with negative effects on credits earned, course achievement, and degree attainment (Valentine, Konstantopoulos, & Goldrick-Rab, 2017) and requires substantial investments with costs to students and institutions estimated at $1.3 and $7 billion (Ganga, Mazzariello &…

This study was a quasi-experimental design (QED) that examined the impact of Intervene K-12 tutoring on mathematics achievement for Grade 9 ELL students identified by HPS as having experienced considerable learning disruptions as a result of the COVID-19 pandemic and having recently arrived in the United States. Achievement gains for treatment…

This applied experimental research tested the effectiveness of a universal, student-focused intervention ('Memory Mates'), specifically focused on supporting students to use attention and working memory strategies within academic contexts, unlike computer-based programs. Memory Mates is presented in the form of icons and explanations, with the…

We systematically examine the existing evidence and compute meta-analytic averages for the effects of scaled-up, publicly funded pre-kindergarten (pre-K) programmes in the United States on student mathematics and reading achievement. The analysis is restricted to experimental and quasi-experimental research designs with the highest internal…

Improving student success rates in introductory calculus and physics courses is critically important for our students' path in STEM fields. Many of the students who have an intuitive understanding of physics fail calculus and are pushed to delay or drop their majors in technical fields. One way of addressing this issue is by adopting a program…

This Campbell systematic review examines the effects of targeted school-based interventions on standardised tests in reading and maths. The review analyses evidence from 71 studies, 52 of which are randomised controlled trials. School-based interventions targeting students with, or at risk of, academic difficulties in Grades 7-12 have on average…

We study the Tutoring Online Program (TOP), where: (i) tutoring is entirely online; (ii) tutors are volunteer university students, matched with underprivileged middle school students. We leverage random assignment to estimate effects during and after the pandemic (2020 and 2022), investigating channels of impact. Three hours of individual tutoring…

The study described in this paper investigated a unique collaboration among a special education and two general educators that sought to prepare students for success in the general education mathematics curriculum and that consisted of coordinated, reform-based instructional design across classroom and pull-out services provided by the special…

Access to high-quality computer science education remains uneven across the United States, with rural schools facing persistent barriers including limited staffing, outdated infrastructure, and constrained professional development opportunities (Gutierrez & Terrones, 2023; Showalter et al., 2019). Computer Science in Rural California (branded…

Zearn Math is a popular software platform for K-8 mathematics learning, designed to enable all students to successfully access grade-level content. RAND researchers collaborated with Zearn, the product's developer, to design this evaluation. Then RAND conducted the study independently, randomly assigning 64 schools in an urban Texas district to…

This study evaluates the first year of implementation of "How Are the Children" (HATC), a project-based social-emotional learning (SEL) curriculum designed to enhance high school student's social-emotional (SE) development. Through documentary filmmaking and lessons based on SE competencies, HATC aims to provide SEL support that…

In December 2022, Rock Island-Milan School District #41 (RIMSD), in partnership with the Connect with Kids Network (CWK) and Empirical Education, received an early-phase Education Innovation and Research (EIR) grant from the U.S. Department of Education. RIMSD contracted with Empirical Education to conduct a one-year teacher-level randomized…

This policy brief examines the impact of Solution Tree's PLC at Work® process on student achievement in Texas schools. Using a quasi-experimental design and statewide data, we found that students in Model PLC Schools made meaningful academic gains, averaging 3.1 months of additional learning in math and 2 months in reading compared to similar…

This report evaluates the impact of the Professional Learning Communities (PLC) at Work® process on student academic achievement over a three-year period in Texas public schools. Drawing on linked administrative data from the University of Houston Education Research Center (UH-ERC), the study uses a quasi-experimental approach to compare…
