This study uses Early Childhood Longitudinal Study data to investigate the importance of three general aspects of teacher effects--teacher background qualifications, attitudes, and instructional practices--to reading and math achievement gains in first grade. The results indicate that compared with instructional practices, background…

This article exploits highly detailed data on teacher absences from a large urban school district in the northern United States to shed light on the determinants and effects of teacher absences. The topic is important because both school and district policies can influence teachers' propensity to be absent. The authors estimate the impact of…

Ability grouping is sometimes thought to exacerbate inequality by increasing achievement gaps; however, ability grouping may in fact benefit a fast growing and often marginalized student population: children from non-English-speaking home environments. The level-appropriate, small-group instruction received in reading ability groups may be…

In addition to identifying and developing superior classroom teaching, the National Board for Professional Teaching Standards (NBPTS) certification process is intended to identify and cultivate teachers who are more engaged in their schools. Here the authors ask, "Does NBPTS certification affect the number of colleagues a teacher helps with…

Using multilevel models, the authors tested the hypothesis that high schools, through their curricular policies, operate as mechanisms that help members of privileged groups to take better advantage of postsecondary opportunities. The analysis was based on a 7-year follow-up study of 44,666 Israeli students who graduated from 385 high schools in…

While state legislatures are increasingly enacting articulation policies, research to date provides little evidence that these policies enhance students' likelihood of transfer. Based on a careful historical review of state statutes, the authors propose that articulation policies do not improve transfer rates because that is not their intended…

Policy makers increasingly include provisions aimed at fostering professional community as part of reform initiatives. Yet little is known about the impact of policy on teachers' professional relations in schools. Drawing theoretically from social capital theory and methodologically from qualitative social network analysis, this article explores…

This study examines 4 years of small school reform in Chicago, focusing on schools formed by converting large traditional high schools into small autonomous ones. Analyzing systemwide survey and outcome data, the authors assess the assumptions embedded in the reform's theory of change. They find that these schools are characterized by more…

This article evaluates changes in racial and ethnic composition of three Texas universities following the ban on affirmative action imposed by the 1996 "Hopwood" decision. The authors estimate the extent to which universities practiced affirmative action before the ban and evaluate how officers at these universities responded by changing relative…

In this article, the authors describe the state of teacher education in and around the large and diverse school district of New York City. Using multiple data sources, including program documents, interviews, and surveys of teachers, this study attempts to explore the characteristics of programs that prepare elementary teachers of New York City…

The influence of teachers' qualifications on their teaching practice has been subject to debate. Literature reviews do not settle these debates, partly because the literature is uneven and partly because reviews capture only narrow slices of literature. In particular, many reviews eliminate qualitative studies. Yet without examining qualitative…

Using national transcript data, the authors examine inequality in access to an advanced curriculum in high school and assess the consequences of curricular intensity on test scores and college entry. Inequalities in curricular intensity are primarily explained by student socioeconomic status effects that operate within schools rather than between…

In this article, the authors report achievement outcomes of a multisite cluster randomized field trial of Open Court Reading 2005 (OCR), a K-6 literacy curriculum published by SRA/McGraw-Hill. The participants are 49 first-grade through fifth-grade classrooms from predominantly minority and poor contexts across the nation. Blocking by grade level…

Successful implementation of evidence-based educational practices at scale is of great importance but has presented significant challenges. In this article, the authors address the following questions: How does the level of on-site technical assistance affect student outcomes? Do teachers' fidelity of treatment implementation and their perceptions…

Research has consistently shown that older students--those who enter college for the first time at age 25 or older--are less likely to complete a degree or certificate. The authors estimate a single-risk discrete-time hazard model using transcript data on a cohort of first-time community college students in Florida to compare the educational…
