In an effort to reduce viral transmission, many schools are planning to reduce class size if they have not reduced it already. Yet the effect of class size on transmission is unknown. To determine whether smaller classes reduce school absence, especially when community disease prevalence is high, we merge data from the Project STAR randomized…

The California class size reduction program provided schools with cash rewards for K-3 classes of 20 or fewer students. I show how program rules made it possible for schools to save money by using mixed-grade classes to meet class size reduction obligations while maintaining larger average class sizes. I also show that this smoothing of students…

Used Tennessee Project STAR data to examine the impact of the duration of participation in small classes on K-3 students' later school performance. Year in which students started and number of years they participated in small classes were important mediators of benefits gained. Starting early and continuing for at least 3 years were necessary to…

Four years of research in Tennessee involving more than 6,000 students each year demonstrate that smaller classes can provide substantial gains in student achievement, especially in the early grades. Lists 10 information sources about the effects of class size on student learning. (MLF)

Small classes in grades K-3 boost student academic performance in all subjects and in prosocial behavior. Results are both short- and long-term. One study explored the theory that a major cause behind improved academic achievement involves improved student behavior, which increases student engagement in the classroom. Two other studies provide…

The Federal government will spend $1.2 billion in 1999-2000 on the Clinton administration's Class Size Reduction Initiative. Research on K-3 class-size reduction experiments (such as Tennessee's Project STAR) show positive achievement gains, particularly for minority and inner-city students. However, better teaching and learning must be a program…

The education reform movement has fostered renewed interest in class size. Tennessee and Indiana experiments with smaller class size in primary grades have yielded improved student behavior and achievement scores. Tennessee's new Student-Teacher Achievement Ratio Project (STAR) is a longitudinal study furthering research on small class benefits.…

In 1984, the North Gibson School Corporation (Princeton, Indiana) began a reduced class size program as part of the PRIME TIME project investigating the effects of smaller classes on pupils' academic achievement, self-concepts, and attitudes toward school. Results showed significant gains for both first- and second-graders. Includes two tables and…

This report, intended for local and state policy makers and practitioners, summarizes the findings and implications of class-size reduction (CSR) in California. The report's findings provide a comprehensive picture of California's CSR initiative during its first 2 years, covering such topics as implementation, resources, teacher qualifications,…

A primary purpose for reducing the student-teacher ratio in the early grades is to make students more successful in their later years. This document contains two separate, but interrelated reports that examined two aspects of the 1989 Class Size Reduction (CSR) Act in Nevada. The Act called for a reduction in student-teacher ratios for selected…

The major purpose of this study was to determine if there were meaningful differences between work-related problems of 310 first-grade teachers assigned to small classes, regular size classes, and regular size classes with full-time aide assistance. This paper reports on the analysis of results of a single data source from the second year of…

A study was conducted to determine the effects of class size on the reading achievement of 517 representative Madison (Wisconsin) students in a three year longitudinal sample. Data included reading achievement, IQ, attitudes toward reading, parents' and teachers' ratings of student interest in reading, sex, age, socioeconomic status, and average…

Describes several prominent early grades small-class-size projects and their effects on student achievement: Indiana's Project Prime Time, Tennessee's Project STAR (Student/Teacher Achievement Ratio), Wisconsin's SAGE (Student Achievement Guarantee in Education) Program, and the California class-size-reduction program. Lists several conclusions,…

This paper addresses three questions policymakers may have concerning the results of the Project STAR data. First, when reducing class size, is there a "turning point" at which class size reductions lead to increased gains in student achievement? Second, do small classes help low socioeconomic status "at risk" students more…

The effect of class size reduction on grades and retention was investigated. Class size for second and third graders in a rural school district was reduced from an average of 24 in second grade to an average of 20 students per class and an average of 25 in third grade to an average of 22 per class. The purpose was to investigate whether the…
