Early childhood is a sensitive period for learning and social skill development. The maturation of cerebral regions underlying social processing lays the foundation for later social-emotional competence. This study explored myelin changes in social brain regions and their association with changes in parent-rated social-emotional development in a cohort of 129 children (64 females, 0–36 months, 77 White). Results reveal a steep increase in myelination throughout the social brain in the first 3 years of life that is significantly associated with social-emotional development scores. These findings add knowledge to the emerging picture of social brain development by describing neural underpinnings of human social behavior. They can contribute to identifying age-/stage-appropriate early life factors in this developmental domain. 相似文献

Teacher moonlighting (teachers working other jobs in addition to teaching) may have positive as well as negative implications. In the context of post-socialist countries, the provision of private tutoring is one of the common forms of teacher moonlighting. The aim of the paper is to analyse the prevalence and factors that are associated with a) having a paid job in addition to one’s regular teaching obligations; b) provision of private tutoring among teachers. Results are drawn from a representative sample of 494 Czech teachers of academic school subjects in lower secondary schools who responded to an online questionnaire survey. Male teachers working part-time, with shorter professional experience, higher household financial burden and lower satisfaction with teacher salaries were more likely to moonlight. The provision of private tutoring was only associated with shorter professional experience and the teaching of core subjects, suggesting that Czech teachers’ motivation to provide private tutoring is currently not primarily financial. 相似文献

There is growing interest in using measures of teacher applicant quality to improve hiring decisions, but the statistical properties of such measures are not well understood. We use unique data on structured ratings solicited from the references of teacher applicants to explore the dimensionality of measures of teacher applicant quality and the inter-rater reliability of the reference ratings. Despite questions about applicants designed to capture multiple dimensions of quality, factor analysis suggests that the reference ratings only capture one underlying dimension. Point estimates of inter-rater reliability range between 0.23 and 0.31 and are significantly lower for novice applicants. It is difficult to judge whether these levels of reliability are high or low in the current context given so little evidence on applicant assessment tools. 相似文献

This paper documents a robust achievement gap between the math scores of Indigenous and white youth in Canada between 1996 and 2008. Using data from the restricted-access National Longitudinal Survey of Children and Youth we show that after controlling for a rich set of observables, students who self-identify as Indigenous perform 0.31 standard deviations lower on a standardized math test compared to their white counterparts. We find that this test gap emerges by the age of 12, and it did not decline between 1996 and 2008, despite the recommendations of the 1996 Royal Commission on Aboriginal Peoples to ameliorate the public education system for Indigenous students. Counterfactual estimates from the decomposition method of Lemieux (2002) suggest that the test gap among the lowest performing students would have been eliminated if Indigenous students faced the same level of and returns to observable characteristics as white students. This exercise does not result in a narrowing of the test gap in the upper tail, suggesting that unobservables, rather than observables, are driving the majority of the test gap among high achieving students. 相似文献

To prevent children from falling behind in the developmental sequence of reading, a shared vision of what reading success looks like is required. This paper provides the first benchmarks for early grade oral reading fluency that are necessary (albeit not sufficient) to read for meaning in three Nguni languages – isiZulu, isiXhosa and Siswati - belonging to the Southern Bantu family of African languages. In contrast with previous benchmarking methodologies, our approach is informed by a non-parametric analysis of longitudinal early grade reading assessment (EGRA) data, guided by reading development theory. The EGRA-type data used for this analysis is the largest compilation of data on early grade fluency in these languages, with comparative assessments for nearly 14,200 children. Analysing empirical regularities and reading trajectories, we identify a lower fluency threshold of 20 correct words per minute (cwpm) and an upper fluency benchmark of 35 cwpm for the early grades. These benchmarks contribute to guiding curriculum policy, provide specificity to improve tracking of literacy progress and address gaps in the literature on reading in African languages. 相似文献

Using PISA and PIAAC data from twelve OECD countries, we examine the gap in cognitive skills among immigrants and natives and evaluate how those differences have evolved over time. We also consider how demographics, family background and school quality explain the development of cognitive skills of young people with immigrant backgrounds. The results show, first, that some convergence in skills occurs between second-generation immigrants and natives over time. Second, demographics, family background and school quality variables all contribute to the achievement gaps across different groups. 相似文献

This study analyses the prevalence of sexting and the reasons and attitudes associated with its practice in adolescents with different cultural backgrounds (Colombia and Spain). The sample is made up of 489 Spaniards and 510 Colombians aged between 13 and 18 years. The results show that sexting is strongly influenced by gender and the country, in favor of men and Colombians respectively. The interaction between gender and country establishes that in Spain women and men practice sexting equally, while in Colombia men practice much more sexting than women. Although the practice of sexting increases progressively with age, the levels are higher among Colombian adolescents, especially after 15 years. According to the results, although both groups present a high risk for sexting, socio-cultural aspects and gender constitute differential variables to be taken into consideration. Therefore, it is necessary to design preventive strategies including cultural differences in relation to the sexuality. 相似文献
