This longitudinal study investigated the effects of maternal emotional health concerns, on infants’ home language environment, vocalization quantity, and expressive language skills. Mothers and their infants (at 6 and 12 months; 21 mothers with depression and or anxiety and 21 controls) provided day-long home-language recordings. Compared with controls, risk group recordings contained fewer mother–infant conversational turns and infant vocalizations, but daily number of adult word counts showed no group difference. Furthermore, conversational turns and infant vocalizations were stronger predictors of infants’ 18-month vocabulary size than depression and anxiety measures. However, anxiety levels moderated the effect of conversational turns on vocabulary size. These results suggest that variability in mothers’ emotional health influences infants’ language environment and later language ability.  相似文献

It has been shown (Lawrence, S. (2001). Online or invisible? Nature, 411, 521) that journal articles which have been posted without charge on the internet are more heavily cited than those which have not been. Using data from the NASA Astrophysics Data System (ads.harvard.edu) and from the ArXiv e-print archive at Cornell University (arXiv.org) we examine the causes of this effect.  相似文献

The purpose of this randomized experiment was to compare the performance of high-, average-, and low-achieving middle school students who were assessed with parallel versions of a computer-based test (CBT) or a paper-pencil test (PPT). Tests delivered in interactive, immersive environments like the CBT may have the advantage of providing teachers with diagnostic tools that can lead to instruction tailored to the needs of students at different achievement levels. To test the feasibility of CBT, students were randomly assigned to the CBT or PPT test conditions to measure what they had learned from an instructional method called enhanced anchored math instruction. Both assessment methods showed that students benefited from instruction and differentiated students by achievement status. The navigation maps generated from the CBT revealed that the low-achieving students were able to navigate the test, spent about the same amount of time solving the subproblems as the more advanced students, and made use of the learning scaffolds.

This article contrasts the often ambivalent attitudes of teachers towards television and generalised research on teachers’ uses of television, with detailed empirical evidence from primary school history co‐ordinators describing their reactions to and expectations of the medium. The data describes a wide variety of reasons why television is educationally useful in the teaching and learning of history. The argument is articulated that teachers and children can be sophisticated viewers of televisual schools history, offering useful guidelines for programme makers; but that teacher conservatism and lack of advisory support for teachers’ deployment of the medium may be hindering its educational effectiveness.  相似文献

In this paper we explore the avowedly partisan stance of Australia regarding trade in education services, the government's enthusiastic approach to market liberalisation through GATS, and its response to the concerns of vocal critics including academic and student unions. Education is a major export enterprise for Australia, both onshore and offshore. Education is publicly referred to as an ‘industry’ as often as a ‘sector’, and institutions behave in an aggressively market‐oriented manner unthinkable two decades ago. While other major education exporters, including the EU, US and Canada, have showed flagging commitment to pursuing trade liberalisation in education due to opposition from the academic community and little pressure from the ‘industry’ for such an approach, Australia and New Zealand have come to represent the most ardent supporters of free trade in education. The Australian government's approach has involved making changes to its domestic education regulations to ensure they are consistent with market liberalisation, and facilitating the exploration of concerns through various international forums, including APEC, the WTO and OECD. Issues such as quality assurance, consumer protection, and public subsidies remain high on the list of matters for further debate.  相似文献

OBJECTIVE: The prevalence of childhood sexual abuse among Latino adult men who have sex with men who live in the US was estimated because a history of childhood sexual abuse increases HIV sexual risk behaviors and other negative health outcomes in adulthood. METHOD: The Urban Men's Health Study is a random-digit telephone probability survey of 2881 adult men who have sex with men (MSM) aged 18 years or older residing in San Francisco, New York, Los Angeles, and Chicago. Self-reported history of childhood sexual abuse was the main outcome measure gathered from 2692 MSM. RESULTS: A significantly higher proportion of Latino MSM reported sexual abuse before age 13 (22%) than did non-Latino MSM (11%). CONCLUSIONS: Latino MSM are twice as likely to report a history of childhood sexual abuse than are non-Latino MSM. Given the association between childhood sexual abuse and increased risk for HIV and other negative health outcomes, health providers must remain vigilant to the possibility of childhood sexual abuse histories among their Latino patients.  相似文献

The millennium round of the General Agreement on Tradein Services (GATS) underlines issues relating to the regulationof education as an internationally traded service. Transnationaleducation is a key component of such trade. Southeast Asia issomething of a laboratory in the development and regulation oftransnational education. The region combines high demand, keencompetition among providers, and host country regulatory regimesranging from relatively laissez faire to strongly interventionist.This paper examines the approaches of three Southeast Asiangovernments – Hong Kong, Malaysia and Australia – to theregulation of transnational education within their borders. Ineach case the authors provide background on the higher educationsystem, describe the regulatory approaches to transnationaleducation, and analyse the motivations behind regulation. Boththe neoliberal approach of the WTO to trade in educationalservices, and critiques of this approach, are outlined. Theauthors conclude that any attempts to promote global standards orquality principles for transnational education must address themyriad concerns of governments, including consumer protection,advancing national goals and protecting the local system.  相似文献

Opportunities are increasing for students with intellectual and/or developmental disabilities to attend postsecondary education programs located at college campuses around the nation. Students who attend postsecondary education programs experience numerous positive outcomes, including independent living skills and expanded social networks. However, although parent‐professional partnerships could significantly enhance long‐term outcomes such as competitive employment and independent living, there is a paucity of information about the nature of these partnerships in postsecondary settings. The purpose of this expository article is to describe how staff from a midwestern postsecondary education program facilitate parent‐professional partnerships through parent involvement and support.  相似文献
