Substance use disorders are considered externalizing disorders, defined by anti-social and impulsive behavior, as opposed to internalizing disorders, defined by anxious and depressive thinking; however, that strict binary is increasingly untenable. In this dissertation, I evaluate the co-development of internalizing and externalizing symptoms…

Principals and superintendents operating in high-choice environments are often faced with enrollment challenges as they compete for students. This case study examines the experience of a principal at Crossroads Elementary--a high-performing, culturally responsive, and innovative traditional public school that struggles to retain many of its older…

School suspension and expulsion are not limited to middle and high school students; these exclusionary approaches to discipline begin in early childhood settings such as elementary schools. Most studies regarding exclusionary discipline have been conducted on the middle and high school level, but there are very limited studies regarding…

Recent studies of charter school effectiveness have questioned whether charter school networks can produce a lasting impact on students' long-term outcomes. Our study is the first to examine this issue at the network of Knowledge is Power Program (KIPP) schools, which primarily serve disadvantaged students of color and constitute the nation's…

This study identified the relationships among English Language Arts teacher teams, their collaboration in creating formative assessment, and its impact on the academic achievement of middle school students. The setting of this study was two urban private Nursery through Grade 8 elementary schools in 1 New York City district. The design for this…

A growing number of autistic students enter the school system, many with the capabilities of doing grade-level work. For these students, there seems to be a lack of focus on executive functioning, self-regulation, daily living skills (DLS), and self-determination. The Independence Curriculum (IC) is a set of units addressing identified areas of…

We provide novel evidence on the broader impacts of school choice systems by quantifying disparities in peer continuity from middle to high school in New York City. We find that Black and Hispanic students and those in high-poverty neighborhoods attend high school with a much smaller fraction of their middle school or neighborhood peers than their…

The "Playground Physics" program combines informal, play-based, embodied learning experiences to support middle school students' engagement with and motivation to learn about complex and abstract physics concepts. This experimental design study examines the impact of "Playground Physics" on students' science motivation,…

Since the advent of the standardized movement in education, there has been a plethora of research pertaining to the characteristics of successful schools.

As a result, experts have suggested a number of specific strategies for organizing middle schools in order to best meet students' needs. This Information Capsule summarizes middle school redesign initiatives that…

Inequities in exclusionary discipline result from a complex process involving students, families, and school personnel. However, little research has explored the topic from parent perspectives. This study used parent survey data from New York City to investigate the link between school-family relationships and students experiencing exclusionary…

New York City's school system is among the most diverse and segregated in the United States. Using difference-in-differences and placebo tests, we evaluate two desegregation policies in two geographic districts in New York City, District 3 and District 15. Both districts attempted to lower economic segregation within their district while…

The purpose of the investigation was to determine if there was a difference in student performance on the NYS Mathematics State Assessment between schools that implemented PBL versus those that did not. The aim was also to determine if there was a difference in students' and teachers' attitudes about the school community, specifically in rigorous…

Background/Context: Macro-analyses have documented the raced and classed consequences of rampant economic inequality in schools and society. However, in educational research, there remain clear gaps in understanding how schoolteachers, especially those working with children, locate the appearances of economic inequality in their teaching and how…

Critics of charter schools in New York City, America's largest school district, often allege that charters score better on standardized tests, on average, than traditional public schools because charters "cream-skim" (i.e., attract) the brightest, most motivated, students. Yet this accusation neglects the fact that not all traditional…
