This article examines the impact of within-class age differences on educational outcomes, using students' birth months in Madrid's primary schools as a natural experiment. Employing a regression discontinuity design, we analyze third-grade students to investigate these age-related effects. Additionally, we explore whether early childhood education…

A homogeneous distribution of students in a class is accepted as a key factor for overall success in primary education. A class of students with similar attributes normally increases academic success. It is also a fact that general academic success might be lower in some classes where students have different intelligence and academic levels. In…

This study investigates the impact of the presence of students identified as having special needs (SEN) on their classmates' achievements in reading comprehension. Multi-level regression modelling was conducted with the data of more than 75,000 fourth graders of 4,937 classes in Austria. Students' scores of reading comprehension were used as the…

This study examined the effects of an SLP-delivered whole-class interactive book reading intervention and a professional development program on children's self-initiated participation. Eleven kindergarten teachers and the children in their classes participated in this quasi-experimental study. They were filmed during book reading at pre- and…

Interventions that target on-task behavior are essential, as on-task behavior is linked to the amount of learning that occurs in a classroom. "On-Task in a Box" is a manualized intervention to increase on-task behavior that utilizes video modeling and self-monitoring in conjunction with group contingencies. The current study evaluated…

Background: Whilst much interest is focused on gender, and classroom-level influences such as and classroom composition and teaching style on achievement, attitudinal outcomes have not received the same attention. This paper focuses on alienation from learning as one sub-dimension of school alienation. School alienation is a relevant issue for all…

Student attendance is both a critical input and intermediate output of the education production function. However, the malleable classroom-level determinants of student attendance are poorly understood. We estimate the causal effect of class size, class composition, and observable teacher qualifications on student attendance by leveraging the…

At-risk students are overrepresented in disadvantaged segregated primary schools. Often, these students begin with an educational delay and have less parental support, which makes them more dependent on the quality of their education. Since quality of education depends in great measure upon mechanisms at the class level, it is crucial to gain…

Though schools do not track in Brazil, I find that black/white classroom segregation in Brazil is greater than recent estimates from North Carolina high schools (Clotfelter et al., 2020). How does race-based classroom segregation occur without tracking, and in a supposed "racial paradise," no less? Using national, student-level data…

Comparing teachers' self-assessment to classes' assessment of quality of teaching can offer insights for educational research and be a valuable resource for teachers' continuous professional development. However, the quality of teaching needs to be measured in the same way across perspectives for this comparison to be meaningful. We used data from…

Although peer victimization in school mainly takes place between children in the same classroom or grade and bullying is generally seen as a group process, little is known about how stability and change in classroom composition affect peer victimization. Hence, this study addressed the following questions: (a) Are newcomers in the classroom more…

Students' executive functions (EFs) are linked to school success. Although school-age children spend much of their time interacting with peers, few studies have explored how children's classmates may promote EF development in elementary school. In this study, we test whether mean levels and variability in classmates' EF skills are associated with…

Teacher recommendations are an important factor in the process of track placement, but research has shown that they are biased by pupils' social background. Pupils from higher socio-economic backgrounds are more likely to get the advice to enrol in an academic track than pupils from lower socio-economic backgrounds, irrespective of prior…

Development of fraction number line estimation was assessed longitudinally over 5 time points between 4th and 6th grades. Although students showed positive linear growth overall, latent class growth analyses revealed 3 distinct growth trajectory classes: Students who were highly accurate from the start and became even more accurate (n = 154);…
