This study uses data from a comprehensive database of U.S. early childhood education program evaluations published between 1960 and 2007 to evaluate the relationship between class size, child-teacher ratio, and program effect sizes for cognitive, achievement, and socioemotional outcomes. Both class size and child-teacher ratio showed nonlinear…

I gathered 77 randomized experiments (with 111 treatment arms) that evaluated the effects of school-based interventions on learning in developing-country primary schools. On average, monetary grants and deworming treatments had mean effect sizes that were close to zero and not statistically significant. Nutritional treatments, treatments that…

The budget crises will have far reaching impacts on education in California. This CenterView focuses on the critical issues of equity and teaching quality now beginning to emerge for Californians as they struggle to offer students instruction necessary to meet the state's rigorous academic standards. It is absolutely essential for educators and…

High quality evaluation research has demonstrated that smaller classes with a heterogeneous student composition can increase academic achievement and close the achievement gap. Research suggests that changes occur in the classroom naturally as a result of smaller size without efforts by teachers or students to do anything different. With fewer…

A bibliographic study was made of current research on class size, providing an historical overview of selected class size studies and a review of conclusions applicable to class size. A central theme which runs through the literature concerning class size reduction is that academic achievement does not necessarily improve when student-faculty…

The author examines four categories of context variables (teacher characteristics, school policy and organization, instructional setting, and student characteristics) relating to teaching and learning in studies of teacher effectiveness, and argues that, by identifying contextual constraints within which teachers make decisions, teachers will be…

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)

Hoping to inspire greater cooperation among local school boards, administrators, teachers, and state officials, this paper reviews class size research and analyzes effective instructional methods and student learning related to class size issues. The New York State Board of Regents should not standardize class size, since standardization undercuts…

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)

Research evidence on the effectiveness of various methods of teaching at the university level are reviewed. Evidence is presented in the following areas: the effect of class size; large group instruction techniques; individualized learning, independent study, and programmed instruction; lecturing versus other methods; and laboratory teaching. The…

Discusses the relevance to class size policy of research studies on effective schools, mastery learning, organizational theory, and effective teaching. Class size should be matched to student needs. (BJV)

Using information gathered through a study funded by the New Zealand Minister of Education, this document examines the history and implementation of the New Zealand government's 1:20 teacher-pupil ratio policy first set in motion in 1985, pupil progress associated with the policy, and related literature about class size. The following papers, each…

In this paper, the authors examine several factors related to class size. The purpose of the presentation is to: (1) trace the evolution of class-size research; (2) briefly describe the Student Achievement Ratio (STAR) class-size experiment; (3) summarize the early and the later student outcomes of STAR participants; (4) outline the…

Relevant research literature does not generally support the notion that class size is a significant variable in learner achievement. This, if true, may be the result of various factors. Although teachers believe that they alter their teaching strategies for different class sizes, this may not be the case. More likely is the possibility that…

This publication describes the first phase of the Classroom Environment: Teaching for Learning Study in Australia, a six-year international research effort to identify correlations between teaching practices and student achievement. The report's first chapter presents a resume of the study and reviews research findings on managerial and…
