In 2002, voters in Florida approved a constitutional amendment limiting class sizes in public schools to 18 students in the elementary grades, 22 students in middle grades, and 25 in high school grades. Analyzing statewide achievement data for school districts from 2004-2006 and for schools in 2007, this study purports to find that "mandated…

Defends positive results of small classes in Tennessee's Student Teacher Achievement Ratio (STAR) Project reported in his March 2002 "Kappan" article. (PKP)

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…

This study examined the effects of teacher aides on students' academic achievement, addressing: whether the presence of a full-time aide in K-3 classrooms would affect student achievement; whether the presence of an aide in the primary grades would affect students' later academic achievement (grades 4, 6, and 8); and whether the nature of aide…

Summarizes research findings on a Tennessee experiment in small classes for primary grades--Project STAR (Student/Teacher Achievement Ratio)--and on similar projects in other states. Discusses effects on student achievement and classroom discipline, effects of small classes versus larger classes with teacher aide, costs, long-term impacts, and…

Describes Tennessee's Student/Teacher Achievement Ratio (STAR) Project, a study of class size, and summarizes its findings with regard to academic achievement and behavior. Positive findings from STAR are providing impetus for class-size-reduction policies. Discusses some criticisms of STAR research and findings. (SLD)

The authors examined the conditions that promote or discourage engagement in the classroom among kindergarten students. Engagement included learning behaviors (on-task behavior) and pro- and antisocial behavior. The authors examined 3 policy-manipulable features of kindergarten classrooms: (a) whether the class met for a half day or full day, (b)…

This investigation addressed 3 questions about the long-term effects of early school experiences: (a) Is participation in small classes in the early grades (K-3) related to high school graduation? (b) Is academic achievement in K-3 related to high school graduation? (c) If class size is related to graduation, is the relationship explained by the…

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…

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 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…

Tennessee's Project STAR (Student Teacher Achievement Ratio), a large longitudinal project involving students in kindergarten through third grade, has provided important information about class-size effects on pupil achievement and development. The project showed that small classes provided higher student outcomes and better student behaviors than…
