The debate between cooperative group learning and individual instruction has long been a focal point in educational discourse. This research study explored these two instructional methodologies' comparative efficacy and benefits in fostering learning outcomes and skill development. This research study was conducted using fifth-grade classes from…

Like most other states, Missouri uses assessments intended to measure whether students are on a pathway to "college and career readiness." The state longitudinal data system now has the capacity to directly test that claim. We make use of 8th-grade assessment (MAP) scores in Math, Science, and Communication Arts for roughly 260,000…

In this quasi-experimental design (QED) study, we examined the impacts of Catapult Learning's Wraparound Supplemental Educational Services program on Grades 6-8 student math and reading achievement in selected schools in a large parochial school district. The primary focus of this report was Wraparound Supplemental Educational Services' impact on…

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…

The arrival of the COVID-19 pandemic had a profound effect on K-12 education. Most schools transitioned to remote instruction, and some used remote testing to assess student learning. Remote testing, however, is less controlled than in-school testing, leading to concerns regarding test-taking engagement. This study compared the disengagement of…

The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, "Student achievement in 2021-22: Cause for hope and continued urgency." The authors investigated two main research questions in this brief: (1) How do achievement gains…

To assess education progress in the early grades and identify achievement gaps, this study examined reading achievement data for kindergarten and grade 1 students in two districts in Illinois: District U-46 (Elgin Area Schools) and District 186 (Springfield Public Schools). Drawing on a different reading assessment in each district, the study team…

This study identifies students' academic trajectories in the middle grades relative to a set of college readiness benchmarks. We apply math and reading college readiness benchmarks to rich longitudinal data for more than 360,000 students across the nation. Student-level and school-level demographic characteristics significantly predict academic…

Important educational policy decisions, like whether to shorten or extend the school year, often require accurate estimates of how much students learn during the year. Yet, related research relies on a mostly untested assumption: that growth in achievement is linear throughout the entire school year. We examine this assumption using a dataset…

Growing evidence suggests that contrary to popular belief, schools mostly do not generate achievement gaps in cognitive skills but, rather, reflect the inequalities that already exist. In the case of socioeconomic status, exposure to school often reduces gaps. Surprisingly little is known, however, about whether this pattern extends to gender gaps…

In this paper, we use NWEA MAP test data to examine variation in students' achievement and growth during the pandemic across multiple dimensions. Consistent with prior evidence, we find that students' test scores in fall 2021, on average, were substantially below historic averages. Moreover, the average scores of students of color, students…

There is growing attention to personalizing education to provide students with more flexibility in their education experiences and more time to master academic content (Pane, Steiner, Baird, & Hamilton, 2015). To personalize education, Legacy High School in Bismarck Public Schools, North Dakota, has implemented a schedule that allows students…

This paper explores treatment effects in three different contexts: an extended school year pilot program in an urban school district, a library summer reading program serving twenty-one urban school districts, and states passing the Equal Rights Amendment during the 1970s and 1980s. Estimates generated using two years of intervention data along…

These are the appendixes for the report, "How Legacy High School Students Use Their Flexible Time." The study examined whether students with different demographic characteristics and academic achievement levels use their flex-time differently. The study found that, on average over the school year, students had approximately 80 minutes of…
