Significant life experience research suggests that the presence of role models, time outdoors, and nature-related media foster pro-environmental behavior, but most research is qualitative. Based on a random sample of middle school students in North Carolina, USA, we found limited positive associations between presence of a role model and time…

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…

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…

Nine generalizations are made about what takes place in smaller elementary and secondary school classes (those with 25 students or less). The generalizations are based on findings from nearly 60 studies. (RC)

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)…

CLASSES WERE DIVIDED EXPERIMENTALLY INTO FIVE OR SIX SMALL GROUPS. EACH GROUP WORKED TOGETHER FOR A PERIOD OF 1 MONTH. EACH OF THE EIGHT PARTICIPATING TEACHERS SELECTED ONE TO SIX PUPILS IN HIS CLASS WHO WERE EITHER DISRUPTIVE OR WITHDRAWN. THESE CHILDREN WERE CALLED THE TARGET PUPILS. THREE TIMES EVERY MONTH THE TEACHER RECORDED THE INTERACTION…

Reviews research that finds teachers assigned to smaller classes do not significantly alter the instructional methods they used in larger classes. (PKP)

Recent research suggests that small (1:15) classes in the primary grades improve a student's chance to obtain a solid educational foundation. Funding has proved a major hurdle to definitive class size research. Also, many class size studies are inconclusive, since few are longitudinal. Tennessee is weighing its burgeoning welfare and correctional…

This literature review focuses on the effects of class size on styles of teaching practice, and on pupil behavior and attainment. Most of the literature is from the United States. Evidence from previous reviews, correlational studies, meta-analyses, and experimental interventions are presented in this document. Much of the existing evidence is at…

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 research brief reviews selected 1986 publications concerning the effects of class size on student achievement, attitudes, and behavior. The following points are made: (1) smaller classes in the lower grades have a positive effect on student learning attitudes and behavior; (2) minority, disadvantaged, and low-achieving students perform better…

The authors examined class size effects on teacher-pupil interactions, pupil engagement, and pupil-pupil interaction. They extended previous research by recognizing the hierarchical nature of observation data and the possible influence of other variables. The study used a time sampling method involving 257 children (aged 10-11 years) in 16 small…

Despite evidence from the USA that children in small classes of less than 20 do better academically there is still a vociferous debate about the effects of class size differences in schools, and considerable gaps in our understanding of the effects of class size differences. This article summarises results from the most complete UK analysis to…

Although experimental results indicate that smaller classes promote higher achievement in early elementary school, the broader literature on class-size effects is inconclusive. This seeming contradiction raises questions about the generalizability of experimental evidence, an issue that this article addresses by examining the effects of class size…
