The purpose of this study was to explore the relationship of the Leader in Me philosophy to students' equitable achievement in school, by measuring the academic achievement of third through fifth graders in suburban Missouri public schools. A secondary purpose of the study was to inform teachers and school leaders of effective strategies for…

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…

Background: Over the last twenty years, retention has increased in popularity with policymakers who are concerned with student achievement and aim to end social promotion (i.e., the practice of advancing a student to the next grade level although they have not yet met the academic expectations of their current grade level). Despite calls to expand…

This research study analyzed the impact of an early college readiness program (ECRP) on students' academic performance on the State of Texas Assessments of Academic Readiness (STAAR) reading and mathematics assessments in Grades 3, 4, and 5. ECRP is a college readiness system designed to support students to reach postsecondary education. The ECRP…

Policymakers have long sought to raise expectations for students through standards-based reform. I examine the extent to which the Common Core State Content Standards (CC) affected student achievement and the size of achievement gaps. I merge together data on preparation for and implementation of the CC with the National Assessment of Educational…

Scaling up educational interventions in the STEM (Science, Technology, Engineering, and Mathematics) field is critical but under-researched. We review and draw implications from a series of studies investigating the long-range impact of an implementation of an early mathematics scale-up model based on learning trajectories. Lasting effectiveness…

In this dissertation, I examine how two major social programs in Kentucky--state-funded preK and Family Resource and Youth Service Centers--impact children's outcomes across the state, including racial, ethnic, and economic equity through elementary school. In each chapter, I will analyze how early childhood opportunities relate to outcomes…

"Learning A-Z" contracted with Empirical Education to study the effectiveness of "Raz-Plus" in Milwaukee Public Schools during the 2016-17 school year. "Raz-Plus" is a literacy program that includes leveled books, skills practice, and digital activities and assessments. This study focused on 3rd, 4th, and 5th grade…

Using a DisCrit intersectional lens and statistical and spatial methods, we trace how the creation of K-8 schools functioned to create pockets of privilege in one urban U.S. school district. K-8 schools were both whiter and wealthier than district averages, serving as "enclave" schools. Although far fewer students with disabilities were…

A multisite cluster-randomized trial (by school) was conducted to examine the effects of a combined mental health literacy and dialectical behavior therapy skills program implemented by teachers on three protective factors related to social and emotional well-being. The sample of eight schools that were randomly assigned to intervention included…

Based on growing evidence of the long-term benefits of enriched early childhood experiences, we evaluate the potential for addressing gender disparities in elementary school through early care and education programs. Specifically, we explore the community-wide effects of two statewide initiatives in North Carolina on gender differences in academic…

This What Works Clearinghouse (WWC) report, part of the WWC's Teacher Excellence topic area, explores the effects of the "eMINTS Comprehensive Program," referred to as "eMINTS" in this report, on student achievement. The strong influence of teachers on student outcomes, as well as the variation in teacher effectiveness, has led…
