In a four-year study of the effect of class size on pupil outcomes in a sample of 36 primary schools in Hong Kong, it has been found that there are few positive differences in attainment between classes set at less than 25 pupils and those of normal size averaging 38. Three cohorts of pupils were studied. In Cohort 1 pupils spent 3 years in small…

Evidence from Project STAR has suggested a considerable advantage of being in small classes in early grades. However, the extra benefits of additional years in small classes have not been discussed in detail. The present study examined the additional effects of being in small classes for more than 1 year. We find that once previous grade…

Serious interest in reducing class size often begins with a key question: What available evidence would support the higher implementation costs? This article discusses positive results of a longitudinal statewide study in Tennessee (Project STAR) and uses findings to specify four guidelines for practitioners and policy makers. Evaluation plans…

SAGE is a five-year class-size-reduction program being implemented in 80 Wisconsin schools. A longitudinal, evaluative study is being conducted in 30 SAGE schools. Small classes have three effects leading to increased individualization: fewer discipline problems, greater knowledge of students, and more teacher enthusiasm (using directive methods).…

Discusses Project STAR, a four-year study of class size reduction on student achievement in the early elementary grades. The paper reviews research on class size, puts Project STAR in context, describes its design and introduces several articles noting research implications for policy debate about class size. (SM)

Tennessee's Project STAR (Student Teacher Achievement Ratio) randomly assigned 7,000 K-3 students to small classes (13-17 pupils), regular classes (22-26 pupils), and regular-with-aide classes. Small classes ameliorate large schools' effects, reduce grade retention and discipline problems, benefit minority students substantially, allow students…

Four initiatives to reduce class size are before the California State Legislature--SB 1414, AB 2449, the Governor's proposal, and AB 2821. Three of them were influenced by the findings reported by Tennessee's Project Student Teacher Achievement Ratio (STAR). Project STAR is a longitudinal demonstration project that since 1985 has examined the…

This paper compares the achievement of first and second grade students in reduced size classrooms with the achievement of previous groups taught in larger classrooms in a Mississippi community. It also examines a longitudinal class size effect through the analysis of student achievement for two years. The subjects involved in the study were 371…

Recent research suggests that small (1:15) classes in the primary grades improve a student's chance to obtain a solid educational foundation. Funding has proved a major hurdle to definitive class size research. Also, many class size studies are inconclusive, since few are longitudinal. Tennessee is weighing its burgeoning welfare and correctional…

This article reports the Project STAR interview study that examined changes in K-3 teacher perceptions after teaching for a year in small classes or regular classes with aides. Teachers believed small classes or aides changed teaching and learning. They became more effective and satisfied and provided more individual attention. (SM)

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…

Tennessee's four-year Project STAR provided one-third class size reduction in early elementary school. Small class students in all types of schools scored significantly higher than regular class students in reading and math. The article discusses lessons learned and cost-effective ways to reduce class size. (SM)

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…

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…

Despite evidence from the USA that children in small classes of less than 20 do better academically there is still a vociferous debate about the effects of class size differences in schools, and considerable gaps in our understanding of the effects of class size differences. This article summarises results from the most complete UK analysis to…
