Racial inequality in exclusionary discipline is a salient educational equity issue. The implications of educators' discretion in administering discipline and the complexity of repeated office discipline referrals (ODRs) and suspensions are reflected in school discipline policy debates nationwide. This brief uses New York City to learn more about…

Over the past 15 years, we have seen an increase in the use of cluster randomized trials (CRTs) to test the efficacy of educational interventions. These studies are often designed with the goal of determining whether a program works, or answering the what works question. Recently, the goals of these studies expanded to include for whom and under…

The Community Eligibility Provision (CEP) is a policy change to the federally administered National School Lunch Program that allows schools serving low-income populations to classify all students as eligible for free meals, regardless of individual circumstances. This has implications for the use of free and reduced-price meal (FRM) data to proxy…

Discipline reformers claim that suspensions negatively affect suspended students, while others suggest reforms have unintended consequences for peers. Using student panel data from the School District of Philadelphia, we implement student fixed effects and instrumental variable (IV) strategies to examine the consequences of suspensions for…

Zero tolerance discipline policies have come under criticism as contributors to racial discipline gaps; however, few studies have explicitly examined such policies. This study utilizes data from two nationally representative data sources to examine the effect of state zero tolerance laws on suspension rates and principal perceptions of problem…

We used population-based, longitudinal data to investigate the relation between mathematics instructional practices used by first-grade teachers in the United States and the mathematics achievement of their students. Factor analysis identified four types of instructional activities (i.e., teacher-directed, student-centered,…

This study challenges the belief that homogeneous ability grouping benefits high-ability students in cognitive and social-emotional development at the expense of their low-ability peers. From a developmental point of view, the authors hypothesize that homogeneous grouping may improve the learning behaviors and may benefit the literacy learning of…

Federal legislation has attempted to move career and technical education (CTE) from a segregated component of the high school curriculum to an integrated element that jointly improves both academic and career readiness. However, concerns remain about the ability of CTE to improve academic learning. Using a nationally representative sample of high…

This study examines public school characteristics, and public and private school market characteristics, associated with participation among elementary-aged students in a means-tested school voucher program in Florida. Participants are more likely than eligible nonparticipants to come from disadvantaged public schools on multiple dimensions. On…

This article discusses a dilemma that confronts reformers who seek to improve the education system yet operate from a position outside that system. On one hand, "external" reformers have found that the implementation of school-level programs is attenuated by a lack of coherence and support in schools' environment. Districts and states…

Research in fields other than education has found that studies with small sample sizes tend to have larger effect sizes than those with large samples. This article examines the relationship between sample size and effect size in education. It analyzes data from 185 studies of elementary and secondary mathematics programs that met the standards of…

In the past two decades, several major initiatives were launched to improve mathematics and science education. One prominent feature in these efforts was a new approach to teaching mathematics and science, referred to as "reform-oriented" teaching. Although past studies suggest this approach may improve student achievement, the relationships…

Procedures used to verify and validate the translation of tests, questionnaires, and other paper-and-pencil measurement devices for cross-cultural use are discussed. Recommendations are suggested for improving translation efforts. (MH)

In an effort to maintain internal validity while maximizing the generalizability of evaluation results, the theory-testing methodology that links program activities to outcomes (program theory) is proposed. To evaluate a program by explicating and testing the program theory is to perform evaluation as theory testing. (PN)

The design and conduct of a national evaluation study is discussed, demonstrating that a control group may not provide the no-cause baseline information expected. Resolution of this problem requires reexamination of paradigms, research practices, and policies, as well as the underlying real world constraints and views that generate them. (PN)
