Estimates the operational costs of nationwide class-size-reduction programs under various policy alternatives, including the specified class size, flexibility in implementation, and whether the policy is targeted toward at-risk students. Depending on the options, estimated costs range from about $2 billion per year to over $11 billion per year.…

Estimated the impact of class size on instructional practices and the use of time in high school mathematics and science courses using data from the National Education Longitudinal Study. Findings reveal that class size has an impact on the use of class time, both instructional and noninstructional. (SLD)

Investigates differences in student perceptions and performance among three distance learning sites taking the same off-campus M.B.A. course with the same instructor. Performance in the two smaller classes was better than performance in the large class. Student characteristics and site variables accounted for more than 50% of variance in…

Small classes in the elementary grades have been shown to boost students' academic performance. However, researchers continue to seek a consistent, integrated explanation of "why" small classes have positive effects. This article forwards the hypothesis that when class sizes are reduced, major changes occur in students' engagement in the…

This paper begins by describing the basic design and scope of Tennessee's Student Teacher Achievement Ratio (Project STAR), which began in 1985. The project was designed to determine the effect of reduced class size on the achievement and development of students in kindergarten through grade three. Findings that demonstrated that students in…

After a brief introduction identifying current issues and trends in research on class size, this brochure reviews five recent studies bearing on the relationship of class size to educational effectiveness. Part 1 is a review of two interrelated and highly controversial "meta-analyses" or statistical integrations of research findings on…

This research brief reviews selected 1986 publications concerning the effects of class size on student achievement, attitudes, and behavior. The following points are made: (1) smaller classes in the lower grades have a positive effect on student learning attitudes and behavior; (2) minority, disadvantaged, and low-achieving students perform better…

This study examined the impact of class size reduction (CSR) on achievement among 3rd, 4th, and 5th grade students with different numbers of years of participation in CSR. Single-year matched gains were calculated for the 1997-1998 and 1999-2000 school years. Student progress was assessed using scores from the SAT/9 reading, mathematics, and…

This report summarizes the findings of some recent pivotal studies of class size, especially as they relate to students at risk. Of particular note is a large-scale study of class size, which was designed to test the conclusions of G. Glass and M. Smith (1978) and G. Robinson (1990) about the advantages of small class size. This study, Project…

This report addresses some of the concerns surrounding smaller classes and looks at whether reduced class sizes result in higher achievement levels, and concludes that it in fact does increase student achievement, so long as classes do not exceed 17 students. But many critics question whether the high cost of reducing classes to 17 or fewer…

As poverty, dysfunctional families, and special needs continue to affect students, educators seek improved ways to start children in formal education. One such approach is to lower the teacher-to-pupil ratios, and recent research shows that this method positively influences pupil achievement. How the process works is not well understood. To fill…

Paper summarizes policy and research implications of several studies on Project STAR, noting relationships between class size and student achievement, class size and teaching, and theories of class size effects. It recommends using class reduction to improve achievement and suggests future research on teaching styles, curriculum objectives, and…

Reviews research into class size effects from a methodological viewpoint, concentrating on various strengths and weaknesses of randomized controlled trials (RCT) and observational studies. Discusses population definitions, causation, and generally sets out criteria for valid inferences from such studies. Illustrates with new findings from data in…

A recent study found no evidence of inadequate state-aid general funding for Oklahoma's mandated elementary class size requirements as they became more restrictive during implementation phases. Over the years, state aid increased on a per-simulated-class basis for grades K-6. State-aid distribution equity also increased. (MLH)

The authors examined class size effects on teacher-pupil interactions, pupil engagement, and pupil-pupil interaction. They extended previous research by recognizing the hierarchical nature of observation data and the possible influence of other variables. The study used a time sampling method involving 257 children (aged 10-11 years) in 16 small…
