The Framework for K-12 Science Education and the Next Generation Science Standards propose that students learn core ideas and practices related to engineering as well as science. To do so, students will need high-quality curricular materials designed to meet these goals. We report an efficacy study of an elementary engineering curriculum,…

Pre-kindergarten (Pre-K) improves the school readiness of all children, but less is known about whether associations between enrollment in Pre-K and different indicators of social-emotional and executive functioning (EF) skills are sustained as children move into and across elementary school. The current study examines associations between…

This research summary accompanies the report "Final Report of the i3 Impact Study of Making Sense of SCIENCE, 2016-17 through 2017-18." Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in…

California State University, San Bernardino (CSUSB) and the Riverside County Office of Education (RCOE) were awarded an Investing in Innovation (i3) Development grant in 2015 to investigate the impact of an early education mathematics program on English Learner students at two rural school districts in Riverside, CA. Teaching English Learners…

This randomized controlled trial examined the efficacy of an elementary school service-learning program, Connect Science (CS), on classroom practices and students' science achievement, civic engagement, and social skills. Fourth grade teachers were enrolled into intervention versus control conditions resulting in 41 classrooms (20 intervention)…

Can a school or district improve student achievement simply by switching to a higher quality textbook or curriculum? We conducted the first multi-textbook, multi-state effort to estimate textbook efficacy following widespread adoption of the Common Core State Standards (CCSS) and associated changes in the textbook market. Pooling textbook adoption…

This study tests the influence of a video-based, analysis-of-practice professional development (PD) program on upper-elementary teachers' science content knowledge, pedagogical content knowledge, and teaching practice and on their students' achievement. Using a cluster-randomized experimental design, the study compares the outcomes for teachers in…

These appendices accompany the report "Final Report of the i3 Impact Study of Making Sense of SCIENCE, 2016-17 through 2017-18." Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in the…

The purpose of this study was to explore the efficacy of fractions intervention with and without an embedded self-regulation (SR) component for third-grade students at risk for mathematics disabilities. Fractions intervention focused on magnitude understanding and word problems. Embedded SR was designed to support a growth mindset (fostering…

In this study, we use microdata from 12 Florida county-level school districts and a regression discontinuity design to examine the effects of early grade retention on the short-, medium-, and long-term outcomes of English learners. We find that retention in the third-grade substantially improves the English skills of these students, reducing the…

A lot of progress has been made in understanding the impact of social and emotional skill building on young children and their ability to engage in expected school behavior. While much of this progress has been directed through the implementation of tiered intervention provided through a Positive Behavioral Interventions and Support (PBIS)…

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…

We examined the effects of a professional development (PD) system designed to support teachers' use of data-based instruction (DBI) to improve early writing outcomes for children with intensive needs. The PD system, called DBI-TLC, provided "tools" for early writing assessment and intervention, "learning modules" including…

Studies have shown that math skills in early childhood are uniquely and strongly predictive of later outcomes across a range of domains and well into adulthood, including the likelihood of graduating from high school and college completion. The Making Pre-K Count and High 5s studies were designed to rigorously test the short- and long-term effects…

Despite the significant evidence base demonstrating the positive impact of the Promoting Alternative Thinking Strategies (PATHS) curriculum on children's social-emotional and mental health outcomes, there has been very little research on its efficacy in improving academic attainment. More generally, the relationship between implementation…
