While the effects of early childhood development on later educational outcomes have been widely studied in western countries, rigorous evidence from sub-Saharan African countries is limited. This longitudinal study uses Zambian children’s developmental outcomes at age six as predictors of educational enrollment and attainment at age 15. Fine motor, receptive language, and early literacy skills were most strongly associated with on-track enrollment. Fine motor skills were most predictive of enrollment. Cognitive, socio-emotional, and executive functioning skills predicted grade repetition. Overall, the results suggest substantial heterogeneity in the associations between domains of early childhood development and adolescent schooling outcomes in Zambia. 相似文献

Research emerging from the USA suggests that holding an incremental theory of intelligence (growth mindset) has a positive impact on academic success. However, limited empirical work has explored this relationship in a UK sample, and there has been a lack of research into the antecedents which might influence the development of certain intelligence beliefs. This study aimed to explore these gaps in the existing literature. Data was collected from 710 9-year-old pupils (UK Year 5). Participants completed attainment tests in Maths and English, and a questionnaire to assess their implicit theories of intelligence (mindset). Socio-demographic information—including gender, ethnicity, free school meal (FSM) status and special educational needs (SEN) status—was also collected. Results showed that pupils eligible for FSM or SEN endorsed more of an entity theory of intelligence than pupils not eligible for either. Analysis of the whole sample showed that attainment significantly correlated with implicit theories of intelligence, however, this relationship did not exist for children with FSM or SEN status. These findings help to elucidate the relationship between implicit theories of intelligence and attainment in the UK, but also suggest the importance of external support in potentially facilitating pupils’ belief systems. Results are discussed in relation to avenues for targeted intervention. 相似文献

Abstract In this meta-analysis, the authors attempted to develop a parsimonious model of factors that account for the significant variability in the findings on the effects of within-class grouping on student achievement. Two weighted least squares regression models were tested using 103 independent findings from 51 studies at elementary through postsecondary grades. Results indicate that the most important study features that accounted for 48% of the total variance include outcome measure source, teacher training equivalence, grouping basis, type of small-group instruction method, grade level, and relative ability of students. Goodness-of-fit statistics indicate that the model fits the data and that the remaining variance may be explained by sampling errors. 相似文献

家庭背景如何影响教育获得:基于居住空间分异的视角 总被引:1,自引:0,他引:1
大量经验研究表明,教育在中国人地位获得中的作用在加强,与此同时,人们也发现来自家庭背景,或者说阶层背景的差异对人们的教育获得的影响也是不可忽视的.那么家庭背景是如何影响人们的教育获得的呢?通过对人们居住空间分异的分析可以发现,家庭背景对人们教育获得的影响,有一部分是通过对教育资源的选择与争夺来实现,而这种选择和争夺又可以通过对基础教育资源分布不均的城市空间的竞争来实现. 相似文献
