In educational effectiveness research, multilevel data analyses are often used because research units (most frequently, pupils or teachers) are studied that are nested in groups (schools and classes). This hierarchical data structure complicates designing the study because the structure has to be taken into account when approximating the accuracy…

Instability in the school population between school entrance and school leaving is not "just a problem of missing data" but often the visible result of the educational problems in some schools and is, therefore, not merely to be treated as missing data but as indicator for the quality of educational processes. Even the most superior value-added…

School effects on students' achievement are relatively small. Another approach, in which students' growth trajectories are the focal point of interest, is able to demonstrate more sizeable school effects. This approach is applied in a study into school compositional effects. The rationale of this study is that in Dutch primary education such…

The main objective of the present study is to gain more insight into the school effects on the development of 2 noncognitive student outcomes, namely, the motivation toward learning tasks and the academic self-concept, and, more specifically, on the consistency of the school effects on these 2 outcomes. Data were drawn from the "Longitudinaal…

The implementation of standards-based accountability (SBA) interventions aimed at improving school performance often focuses on the testing component, at the expense of capacity building. This was the case in South Africa when a SBA programme was instituted by government in 2000, which was accompanied by substantial rises in senior certificate…

This article reports the results of a study in which the basic regression-discontinuity approach to assess the effect of 1 year of schooling is extended. The data analysis covers the 6 grades of secondary education in Cyprus and thus assesses the contribution of secondary education to the cognitive development of 12- to 18-year-old students. A…

This study investigates the relation between distributed leadership, the cohesion of the leadership team, participative decision-making, context variables, and the organizational commitment and job satisfaction of teachers and teacher leaders. A questionnaire was administered to teachers and teacher leaders (n = 1770) from 46 large secondary…

The study examines the effects of classroom achievement grouping (AG) practices on the early mathematics performance of language-minority students and compares their mathematics achievement to that of English-speaking majority students. Using a nationally representative database of the USA, both cross-sectional and longitudinal analyses were done.…

In the last 2 decades, educational systems have developed accountability policies in which schools maintain autonomy for their pedagogical, instructional, and organizational practices (internal control). At the same time, they are held accountable to public authorities (external control) for the quality of their education. It is not clear whether…

This study examined the school and student predictors of early reading outcomes for kindergarten students enrolled in schools that participated in a beginning reading reform program. The study employed a nested design with students nested within schools and applied hierarchical linear modeling analyses to account for the organizational structure…

School quality care has become important in many Western countries. A number of self-evaluation instruments have been developed in response. The goal of these instruments is improving the quality of education. One such system, ZEBO, was developed for performing quality assessment in Dutch primary schools. The use of this self-evaluation instrument…

From 1995, data on students' achievement in schools (i.e., teacher's grades) and all data on achievement in the 5-subject group certificate--the "Matura" exam--have been systematically gathered for the entire yearly cohort of students in upper secondary education in Slovenia. This paper describes an on-line data selection system and data analysis…

The success or failure of a school reform can be measured by whether the reform has become an accepted, effective, and sustainable part of the school's culture. For example, as the National Middle School Association (2003) argued, "new programs must become integral to the school culture" (p. 11) before a school can call itself a "middle" school.…

A handful of studies have found evidence of a gap in academic achievement between students of high- and low-socioeconomic status (SES) families. Furthermore, some scholars argue that the gap tends to widen as students get older. Evidence is, however, inconclusive and relies mostly on limited methodological designs. Drawing on the Hamburg School…

Although homework is generally believed to be an important supplement to in-school learning, research has not yet fully clarified the relationship between homework and achievement. This cross-cultural study analyzed the relationship between homework time and mathematics achievement drawing on data from 231,759 students in 9,791 schools and 40…
