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…

Many studies have shown the benefits of smaller class sizes--including random experiments like the Student Teacher Achievement Ratio Project conducted in 79 elementary schools in Tennessee, which assigned children to either small or regular-size classes, as well as large-scale analyses of small and large classrooms that have occurred naturally.…

This report presents a comprehensive preliminary analysis of how California's Class Size Reduction (CSR) initiative has impacted student achievement during the first 2 years of implementation. The analysis is based on complete student, classroom, and teacher records from 26,126 students in 1,174 classrooms from 83 schools in 8 Southern California…

Much of the economic education literature suggests that the principles of economics class size does not significantly affect student performance. However, study methods have varied in terms of the aggregation level (student or class), the measure of performance (TUCE or course letter grade), and the class size measure (e.g., students who completed…

Competing explanations of class size reduction effects on student academic achievement were tested using student, teacher, and school data collected from nearly 700 classrooms in over 70 schools during the first 3 years of implementation of California's (K-3) Class Size Reduction Program. Five major hypotheses were tested: (1) overall impact of…

Summarizes research findings on a Tennessee experiment in small classes for primary grades--Project STAR (Student/Teacher Achievement Ratio)--and on similar projects in other states. Discusses effects on student achievement and classroom discipline, effects of small classes versus larger classes with teacher aide, costs, long-term impacts, and…

This paper discusses research studies concerning class size and its relation to academic achievement. It also explores whether educational benefits of smaller classes justify the additional cost and whether an optimum class size exists that maximizes educational benefits and cost effectiveness. Following a review of the literature, the paper…

A policy of reducing class size seems sensible, but might have costly, far-reaching implications for students, teachers, and public support for schools. The purpose of this research brief is to summarize 100 class size research studies from 1950 to 1985 and to regroup them into 18 areas of concern. The cluster analysis approach was designed to…

For years the issue of class size has been the subject of hundreds of educational research studies. The effects of class size on student achievement, student and teacher attitudes, instructional setting, and total classroom environment have been examined and re-examined. In general, the findings of these studies have been inconclusive, though for…

This testimonial presents evidence that reduced class size (CSR) has positive effects on student learning in grades K-3. Student achievement is improved in the areas of academics, behavior and discipline, citizenship and participation in and outside school, and development into competent and productive adults. The paper emphasizes that class size…

Discussion and research concerning class size can be traced back at least to the 12th century. An overview of recent research on the subject is provided in this report. The paper, which serves as an introduction to a symposium on class size, examines research that has appeared in the past 20 years, but it concentrates on the results of a…

This study examined the impact of smaller class size on elementary student achievement, focusing on types of instructional strategies utilized, student time on task, academic focus of the classroom, and types of interactions between teachers and students and between students and students. Two long-term class size reduction sites in North Carolina…

Exploring the class-size issue, this paper focuses on the primary grades and asks questions such as "does a reduction in class size promote an increase in academic achievement?" and "how substantial does the reduction in numbers have to be in order for a significant increase to occur?" The paper surveys debates on class size…

A short overview of an experimental evaluation of lower teacher-pupil ratios is presented in this report. The research under review is the Student Teacher Achievement Ratio (STAR) project. This longitudinal project was conducted in Tennessee and was designed to prove to state legislators the efficacy of smaller class sizes. For STAR, evaluation…

Literature on the relation between class size and student achievement is reviewed, and policy alternatives are suggested. Class size reduction strategies, focusing on individual or small group tutoring, are proposed for primary and secondary instruction. Implementing these strategies requires ambitious staff development programs. (SLD)
