This study investigated the effect of class practices on students' learning gains in reading comprehension in the 5th grade. A sample of 4,344 students in 283 classes in 176 schools was studied. Several class practices that have previously been demonstrated to be effective were tested while controlling for student characteristics and…

Educational effectiveness research often appeals to "value-added models (VAM)" to gauge the impact of schooling on student learning net of the effect of student background variables. A huge amount of cross-sectional studies do not, however, meet VAM's requirement for longitudinal data. "Contextualised attainment models (CAM)" measure the influence…

Statisticians have shown the theoretical extent of parameter distortion when the classroom level is ignored in multilevel analyses of schooling. This article illustrates the practical consequences of omitting the classroom for inferences drawn about the extent and mechanisms of schooling effects, using the relationship between reading achievement,…

The purpose of this study is to examine the relationship between school decline and changes in school demographics. Using a population of 981 (N = 981) elementary schools, the authors identified samples of declining schools: Relational Decline (n = 510), Absolute Decline (n = 217), and Crossing the Line (n = 165). Latent growth models assessed…

This paper investigates whether inferences about school performance based on longitudinal models are consistent when different assessments and metrics are used as the basis for analysis. Using norm-referenced (NRT) and standards-based (SBT) assessment results from panel data of a large heterogeneous school district, we examine inferences based on…

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…

There is still little consensus on whether and how teaching is affected by small and large classes, especially in the case of students in the later primary years. This study investigated effects of class size on teaching of pupils aged 7-11 years. We used a multimethod approach, integrating qualitative information from teachers' end-of-year…
