This study systematically summarize existing literature focusing on the correlates of students' moderate-to-vigorous physical activity (MVPA) during elementary school physical education (PE). A systematic search was initiated to identify studies investigating the physical activity correlates in students during elementary PE. Two researchers…

Robust evidence suggesting a strong association between greater educational attainment, better health and lower mortality, has led to speculation that the quality of schooling can also have effects on health. This review critically summarises findings from 15 studies in a growing area of research concerning the effects of school quality on health.…

The proximity effect--whether distance from an instructor correlates with grades--has been the topic of many articles dating back nearly 100 years. Despite this attention, a cleavage in the literature remains. Some authors argue that increased proximity to the instructor negatively relates with academic performance while others maintain no…

A meta-analysis of recent quantitative studies that examine the effects of cooperative learning (CL) on achievement outcomes in chemistry is presented. Findings from 25 chemical education studies involving 3985 participants (N[subscript treatment] = 1,845; N[subscript control] = 2,140) and published since 2001 show positive association between…

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…

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 addresses some of the concerns surrounding smaller classes and looks at whether reduced class sizes result in higher achievement levels, and concludes that it in fact does increase student achievement, so long as classes do not exceed 17 students. But many critics question whether the high cost of reducing classes to 17 or fewer…

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…
