Identifying an appropriate class size is an important decision public schools face as they weigh balancing their budget with the impact class size may have on student achievement. This study examined perceptions of South Dakota kindergarten through third-grade teachers, elementary principals, and superintendents concerning optimal class size and…

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…

This paper explores mathematics teachers' perceptions about class size and the impact class size has on teaching and learning in secondary mathematics classrooms. It seeks to understand teachers' views about optimal class sizes and their thoughts about the education variables that influence these views. The paper draws on questionnaire responses…

Prior research has established the potential for achievement gains from attending smaller classes. However, large statewide class-size reduction (CSR) policies have not been found to consistently realize such gains. A leading explanation for the disappointing performance of CSR policies is that schools are forced to hire additional teachers of…

Background/Context: One important question to educational research is whether teachers can influence student achievement over time. This question is related to the durability of teacher effects on student achievement in successive grades. The research evidence about teacher effects on student achievement has been somewhat mixed. Some education…

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…

The main purpose of this study was to determine student teachers' perceptions concerning the effects of class size with regard to the teaching process. A total of 41 fourth-year student teachers participated in the study. A questionnaire including open-ended items was used for data collection. The study revealed that there is a direct relationship…

This paper investigates the effects of California's billion-dollar class-size-reduction program on student achievement. It uses year-to-year differences in class size generated by variation in enrollment and the state's class-size-reduction program to identify both the direct effects of smaller classes and related changes in teacher quality.…

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)

Investigates teachers' beliefs and attitudes on infant school classes in northern England. Reports on class size preferences and preferential treatment for some groups of children and teachers. Indicates that class size cannot be treated as unidimensional in its impact on the quality of teaching and learning. (CMK)

Research on the relationship of class size to academic achievement is being used by administrators, parents, teachers, and politicians. Unfortunately, many questions are being raised on the methodology, results, and conclusions of the research studies. (FG)

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)
