In a study of Ontario, Canada's province-wide Primary Class Size Reduction (PCS) Initiative, school districts' ability to direct and support schools was related to their experience with planning and monitoring, interest in innovation, and its human and fiscal resource base. Districts with greater "resource capacity" were able to…

The Lasting Benefits Study is following up the effects of small class size on the achievement of elementary school students in Tennessee's Student/Teacher Achievement Ratio Project (Project STAR). Results show improved achievement for participants in small classes up through grade 3 that last at least through grades 4 and 5. (SLD)

Alan Krueger's reanalyses of Eric Hanushek's school-productivity data show that Hanushek's "money doesn't matter" conclusions (influential in several states' education-finance hearings) have no factual basis. Hanushek excluded Tennessee's student/teacher ratio study (Project STAR). Also, class size is influencing students' success in…

Conclusive research has shown the benefits of small class size (1:15), especially for primary grades. Large-scale projects in Indiana and Tennessee and numerous smaller studies found that youngsters in small classes obtain higher test scores, participate more eagerly, demonstrate improved behavior, and retain these benefits in later schooling…

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…

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)

Tested whether variations in class size caused teachers to alter their teaching methods. Examination of 2,170 mathematics classes suggests that, when class size is reduced, teachers do not spend time on new material, nor do they finish more of the assigned textbook. Instead, they shift time to more individual instruction. (SLD)

Although class-size reductions cannot guarantee better student performance, the Tennessee and Wisconsin experiences, along with other studies, suggest that successful programs share key characteristics: concentration in the primary schooling years, classes with not more than 20 students, greater benefits for urban minority students, and alignment…

Conducted a 6-year followup of almost 4,000 students in Project STAR in Tennessee, a 4-year, large-scale randomized experiment on the effects of class size. Though follow-up data could not be obtained on more than one-half of the students, class size effects persisted for at least 6 years and remained large enough to be of importance for…

The California Legislature and Governor created the Class Size Reduction (CSR) program as part of the 1996-97 Budget Act. The goal of the program is to increase student achievement by reducing average class sizes from 28.6 students to no more than 20 students in up to 3 grades. The 1997-98 governor's budget proposes expansion of the CSR program to…

Summarizes a major longitudinal study (Project STAR) conducted in Tennessee between 1985 and 1989, provides some results updating STAR findings through 1992, and suggests research-based courses of action. Class-size research in primary grades is showing the efficacy of small classes of 1:15. Application of early experimental results in 17 poor…

Reviews Tennessee's Project Student/Teacher Achievement Ratio (STAR) and puts the results in the context of other nonexperimental evidence about class size. Nonexperimental evidence does not support any achievement gains attributable to class-size reduction, and empirical evidence from STAR has design and implementation flaws that cast doubt on…

Examines the origins of Tennessee's Project Student/Teacher Achievement Ratio (STAR) and explores what it was about Tennessee in the mid-1980s that fostered the development of this experimental approach to class size. Highlights the connection between the research world and the political world that resulted in the STAR project. (SLD)

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)
