Increasing class size is one of the key variables that policy makers can use to control spending on education. But the consensus among many education researchers is that smaller classes are effective in improving student achievement. This view has led to a policy of class size reductions in a number of US states, the UK, and the Netherlands. This…

Understanding the effects of class size reduction (CSR) has been an enduring issue in education. For the past 3 decades, Project STAR has stimulated research and policy discussions regarding the effects of CSR on a variety of outcomes. Schanzenbach (2007) reviewed STAR studies and concluded that small classes improved student academic outcomes.…

States and districts have the flexibility to creatively use Title II, Part A funds to address teacher quality issues. Currently, three strategies predominate--class size reduction, professional development, and recruitment, induction, and retention of highly qualified teachers. Each strategy is implemented with the intention of improving teaching…

Schools across the United States are facing budgetary pressures on a scale not seen in generations. Times of fiscal exigency force policymakers and education practitioners to pay more attention to the return on various categories of public investment in education. The sizes of the classes in which students are educated are often a focus of these…

The purpose of this report was to gather lessons on research-based best practices in blended learning for use by K-12 practitioners, a study commissioned by planning council members of the Metropolitan Educational Research Consortium (MERC). After interviewing representatives from participating school divisions, questions driving the inquiry were…

Class size is one of the small number of variables in American K-12 education that are both thought to influence student learning and are subject to legislative action. Legislative mandates on maximum class size have been very popular at the state level. In recent decades, at least 24 states have mandated or incentivized class-size reduction…

Small classes in grades K-3 boost student academic performance in all subjects and in prosocial behavior. Results are both short- and long-term. One study explored the theory that a major cause behind improved academic achievement involves improved student behavior, which increases student engagement in the classroom. Two other studies provide…

Interest in class size is widespread today. Debates often take place about "ideal" class size. Controversial efforts to reduce class size have appeared at both the federal level and in various states around the nation. This paper reviews research on class size and discusses findings, how these findings can be explained, and policy implications.…

Although class size reductions are often proposed as a way to improve student learning, research does not indicate that smaller classes will necessarily produce improved student achievement. Class size effects on student learning vary by grade, pupil characteristics, subject area, teaching method, and other learning interventions. References…

Research and common sense suggest that smaller classes offer teachers the chance to devote more time to each student, thus improving student learning. To explore the efficacy of improved teacher-student ratios, an overview of research on class sizes is offered in this report. An analysis of findings from initiatives in various states provides…

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…

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…

Class size in elementary grades has taken on added importance recently. Research on the topic is finally getting some attention. Legislative and administrative actions to reduce deficits are pushing for larger class sizes, in addition to eliminating nonessential curricular activities, such as music, drama, and art. In Florida, various institutions…

The author, Deputy Head of Chalk Dell Infant School in Hertford, England, reviews research on the effects of class size and analyzes her own experience with a class of 33 and a class of 23 students. (Editor/SJL)

Finding an unequivocable answer to the class size issue is vitally important to the future of American public education. Sorting out conflicting viewpoints and determining supportable conclusions are this report's primary purpose. Three factors--research motivation, the effects of confounding variables, and problems related to distinguishing…
