In this article, we analyze the relationship between class sizes and examination results in higher education. Data from the University of Stavanger, collected in the Common Student System (FS) in the period from 2011 to 2021, shows that there is a negative correlation between the number of students enrolled on courses and examination results. An…

Class sizes in the United States had been a topic of discussion throughout history. There had been mixed results on whether class sizes influenced student achievement or not. In the qualitative single-embedded case study, nine teachers were interviewed and given an open-ended questionnaire to determine if class sizes influenced student…

This research investigates the impact of class size on student performance in Azerbaijani public secondary schools, utilizing State Examination Center (SEC) final exam scores as a key indicator. Data from the Ministry of Science and Education is analyzed, covering approximately 80,000 9th and 11th-grade students in 4,400 schools. The primary…

From academic years 2003-04 through 2008-09, enrollment in WCPSS grew by more than 26%, from 108,970 to 137,607 students. Such unprecedented enrollment growth presented challenges for the Wake County Public School System (WCPSS). Enrollment outpaced new school construction and led to overcrowding. In addition to constructing mobile classrooms, the…

This paper examines the effect of class size on student's academic and behavioral performance in synchronous online courses, utilizing student-level administrative data and website clickstream data from a research university in China. By examining variations in class sizes within students but across classes, we revealed a significant negative…

The long-term shift toward online learning over the past two decades was greatly accelerated by COVID-19, heightening the urgency in higher education for policies meant to better optimize online environments for student learning. The determination of class sizes for online courses is one such policy. In this hierarchical linear regression of…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of initial variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of pretest variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

This study explores the relationship between seating quadrants and student performance, including the role of classroom type in the quadrant effect. Data collected from 131 classes taught at 17 colleges of Northwest A&F University in China were analyzed using the ordinary least squares method. The results revealed that where a student sat in a…

While research on the relationship between general education class size and student achievement is plentiful, research on class size in special education is scarce, even though class size issues must be considered particularly important to students with special educational needs. This summary is based on a systematic review that sought to examine…

Background: Class size reductions in general education are some of the most researched educational interventions in social science, yet researchers have not reached any final conclusions regarding their effects. While research on the relationship between general education class size and student achievement is plentiful, research on class size in…

The purpose of this correlational study is to determine the nature of the relationship between school and demographic factors and student achievement using data from the individual schools reported by a school district in Northern Texas. Answers to the following questions were sought: Do the teacher demographic factors (years of experience,…

This Research Note discusses research on class size reduction (CSR). The research on CSR is not definitive but a contested, ongoing debate. The research on CSR has been severely limited by the singular focus on student academic performance, although some studies have sought to expand the conversation by focusing on the impact of CSR on teaching…

This study examined the effect of class sizes on differences in the trajectories of elementary school students' long-term Japanese language achievement by analyzing panel data composed of standardized achievement test scores at five points from around the end of first grade to around the end of fifth grade. The data for 103 schools, 162 classes,…

We propose using Stochastic Frontier Analysis to estimate pupils' academic underachievement. We model underachievement as the gap between expected achievement and actual achievement, not due to a learning disability. Our data are a panel for 2,228 Belgian pupils observed over 6 years of primary education. We found that the average underachievement…
