Most states nationwide have had policies for several decades that limit the number of students assigned to public K-12 classrooms. Southern Regional Education Board (SREB) states, led by Tennessee and Texas, spearheaded this effort in the 1980s, and SREB's own "Legislative Briefings" have marked the growth of class-size policies across…

Teachers spend most of their time in school in classrooms, and their instruction and teaching practices may be affected by classroom context such as class size. We examine whether teacher effects interact with classroom context such as class size. Specifically, we seek to determine whether teacher effects are more pronounced in small classes than…

The requirements of various educational reform movements such as No Child Left Behind and Race to the Top have left public education systems searching for ways to make sure students are reaching their highest potential. Because of the importance of accountability issues to school systems, it is important to examine ways to help students reach…

Few questions in public education discourse benefit as much from research-based evidence as the question of class size--the pursuit of the ideal number of students that should be co-located for any particular period of instruction. But for policymakers, research on class size can be an embarrassment of riches, and much of the research appears to…

This Information Capsule examines the background and history in addition to research findings pertaining to class size reduction (CSR). This Capsule concludes that although educational researchers have not definitively agreed upon the effectiveness of CSR, given its almost universal public appeal, there is little doubt it is here to stay in some…

A common criticism of merit-pay plans is that they fail to systematically target rewards to the most effective teachers. This study presents new evidence on this issue by evaluating data from Tennessee's Career Ladder Evaluation System and the Project STAR class-size experiment. Because the students and teachers participating in the experiment…

Tennessee's Project STAR (Student-Teacher Achievement Ratio) analyzes pupil achievement and development in 3 class types: small (15 students), regular (23 students), and regular with a full-time aide, following a cohort of pupils from kindergarten through grade 3. Preliminary results show statistically significantly advantages for students in…

This article discusses what a Tennessee experiment tells about merit pay. Though the dramatic effects that teachers have on student achievement are indisputable, the exact ingredients of effective teaching are anything but settled. Questions about how to value experience, education, certification, and pedagogical skills---the big four of teacher…

According to Tennessee's 4-year study of class size, smaller classes (13 to 17 students) have an advantage over larger classes in reading and mathematics in the early primary grades. Another study showed that fourth graders previously enrolled in Project STAR classes out-performed non-STAR students. Benefits are greater when teachers possess…

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)

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)

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)

Researchers followed up on fourth graders from Project STAR, a reduced class size experiment. Using norm and criterion-referenced achievement tests and teacher ratings of student effort, initiative, and behavior, they found significant small class carry-over effects on every achievement measure and significant participation differences in small…

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…

Article reanalyzes and expands upon data from Tennessee's Project STAR which examined the effects of class size reduction on student achievement in the primary grades. It describes six competing theories of class size impact on achievement and test performance, settling on the student group/modeling interpretation of study data. (SM)
