The "quality " of early care and education settings: definitional and measurement issues 总被引:1,自引:0,他引:1
There is a widespread belief that high-quality early care and education can improve children's school readiness. However, debate continues about the essential elements of a high-quality experience, about whether quality means the same things across different types of care settings, about how to measure quality, and about the level of quality that might make a meaningful difference in outcomes for children. Are the aspects of the child care environment that researchers measure the ones that are most strongly related to children's development? This article argues that the ways in which researchers currently measure early care environments are flawed and that the conclusions drawn about the relationship between these measures and outcomes for children are frequently incorrect or overstated. The article addresses four questions: How is the quality of the child care environment commonly defined and measured? Do the most commonly used measures capture the child's experience? Do they work well across all settings? Are researchers drawing the correct conclusions from studies that relate the child care environment to child outcomes? Finally, the article discusses some possible directions for future research. 相似文献

Relationships are examined between feelings of political competenceand cumulative media usage in five Western nations. Wide differentiationamong the nations studied is found, suggesting that multivariateanalysis is needed to establish whether media usage makes aunique contribution to feelings of political competence, oracts as a surrogate for other background variables. 相似文献

This study focuses on the role macroeconomic factors play in explaining the proportion of decertification elections lost by
the union movement in the postwar period. Previous research has neglected the importance of such macroeconomic variables.
Our results indicate that the union-nonunion wage differential, inflation, strikes, state of the labor market, and union density
are related to the phenomenon of decertification.
The authors would like to thank Greg Hundley, Mike Bognanno, Paul Schumann, Jim Scoville, the editor, and a reviewer for valuable
comments and Michael Wachter and William Wascher for providing some unpublished data. 相似文献
