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

This paper explores recent trends in the size of scientific teams and in institutional collaborations. The data derive from 2.4 million scientific papers written in 110 top U.S. research universities over the period 1981-1999. The top 110 account for a large share of published basic research conducted in the U.S. during this time.We measure team size by the number of authors on a scientific paper. Using this measure we find that team size increases by 50% over the 19-year period. We supplement team size with measures of domestic and foreign institutional collaborations, which capture the geographic dispersion of team workers. The time series evidence suggests that the trend towards more geographically dispersed scientific teams accelerates beginning with papers published at the start of the 1990s. This acceleration suggests a sharp decline in the cost of collaboration. Our hypothesis is that the decline is due to the deployment of the National Science Foundation's NSFNET and its connection to networks in Europe and Japan after 1987.Using a panel of top university departments we also find that private universities and departments whose scientists have earned prestigious awards participate in larger teams, as do departments that have larger amounts of federal funding. Placement of former graduate students is a key determinant of institutional collaborations, especially collaborations with firms and with foreign scientific institutions. Finally, the evidence suggests that scientific output and influence increase with team size and that influence rises along with institutional collaborations. Since increasing team size implies an increase in the division of labor, these results suggest that scientific productivity increases with the scientific division of labor. 相似文献

The primary goal of this research was to extend our understanding of the strengths and weaknesses inherent in online and offline early literacy software programs designed for young learners. A taxonomy of reading skills was used to contrast online software with offline closed system (compact disc) based programs with respect to number of skills taught, quality of instruction and scaffolding during instruction. Overall, online programs were more comprehensive and provided instruction for more skills than offline software at either the Kindergarten or Grade 1 level. However, offline programs demonstrated some developmentally appropriate selectivity in skills trained. Quality of instruction was variable within and across all programs. Scaffolding of instruction was also variable and surprisingly few programs, either online or offline, provided automatic movement across levels of difficulty. These outcomes have important implications for the selection of instructional materials by parents and educators involved in early literacy instruction and also for future software design. 相似文献

Within the field of intellectual disability, progressive policy thinking in Wales has led to an emphasis on the tailoring of services to individual needs and wants of service users, especially through individual planning processes and the creation of service packages. Using an adapted structure‐process‐outcome evaluation model, research is reported about how informal supporters appraise service quality. Based on a survey of 752 families, the first phase of the research reported here has been concerned with charting relationships between personal characteristics of users, service process factors and appraisals by informal supporters of service quality. The findings suggest the importance of key service process factors to an understanding of dimensions of service quality. 相似文献

This paper reviews Australian experience over the period 1981–1983 in order to illustrate how institutional mergers can be used to tackle system-wide as well as local institutional problems in higher education. It also illustrates some of the tensions and complications that arise in a federal political system where the legal control for two out of three sectors of tertiary education lies at one level of government and funding responsibility at another. The background and context to the mergers are explained, an analysis is provided of how institutions and state governments reacted to Federal Government coercion, and an attempt is made to assess outcomes. 相似文献

An Empirical Investigation of the Efficacy of Multimedia Instruction in Counseling Skill Development
B. Grant Hayes Gordon E. Taub Edward H. Robinson Stephen A. Sivo 《Counselor Education & Supervision》2003,42(3):177-188
The purpose of this study was to examine the effects of multimedia instruction on students' counseling skill development. The participants were 73 beginning‐level counselor education students (20 men and 53 women, ages ranging from 24 to 47 years). Ratings of students' pre‐ and posttest video counseling tapes were used to assess the effects of the multimedia approach. The results found that there was no statistically significant difference among the levels of students' counseling skill development across the 3 (high‐tech multimedia, low‐tech multimedia, and traditional instruction) treatment groups. 相似文献

Computers on wheels: an alternative to 'each one has one' 总被引:1,自引:0,他引:1

Four fifth‐grade classrooms embarked on a modified ubiquitous computing initiative in the fall of 2003. Two 15‐computer wireless laptop carts were shared among the four classrooms in an effort to integrate technology across the curriculum and affect change in student learning and teacher pedagogy. This initiative—in contrast to other one‐to‐one programmemess and stationary labs—offers public schools alternatives to budget constraints and instructional‐space overhead. Results indicate positive teacher technology competence and confidence, as well as instructional strategies that were student‐centred made meaningful uses of technology. Teacher technological knowledge and efficacy, pedagogical knowledge, and a supportive school community seem to be strong indicators for impacting technology integration in this context. 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
