This paper examined whether the greater average schooling and employment, and lower parenting competence, of young mothers who reside with adult relatives reflect preexisting differences versus potential causal mechanisms. The sample included 554 young mothers (ages 13 to 25; nearly two thirds African American) from the Infant Health and Development Program (IHDP) a random-assignment intervention study of premature, low birth weight babies followed 8 times from birth to age 3. Ordinary least squares, fixed-effects, and random-effects models indicated that young mothers of low birth weight babies sorted into extended households based on preexisting characteristics that were correlated with their lower parenting skills and knowledge. In contrast, coresidence predicted greater schooling or employment across models, with some variations for different subgroups.  相似文献

Abstract

Background: PISA results appear to have a large impact upon government policy. The phenomenon is growing, with more countries taking part in PISA testing and politicians pointing to PISA results as reasons for their reforms.

Purpose: The aims of this research were to depict the policy reactions to PISA across a number of jurisdictions, to see whether they exhibited similar patterns and whether the same reforms were evident.

Sources of evidence: We investigated policy and media reactions to the 2009 and 2012 PISA results in six cases: Canada, China (Shanghai), England, France, Norway and Switzerland. Cases were selected to contrast high-performing jurisdictions (Canada, China) with average performers (England, France, Norway and Switzerland). Countries that had already been well reported on in the literature were excluded (Finland, Germany).

Design and methods: Policy documents, media reports and academic articles in English, French, Mandarin and Norwegian relating to each of the cases were critically evaluated.

Results: A policy reaction of ‘scandalisation’ was evident in four of the six cases; a technique used to motivate change. Five of the six cases showed ‘standards-based reforms’ and two had reforms in line with the ‘ideal-governance’ model. However, these are categorisations: the actual reforms had significant differences across countries. There are chronological problems with the notion that PISA results were causal with regard to policy in some instances. Countries with similar PISA results responded with different policies, reflecting their differing cultural and historical education system trajectories.

Conclusions: The connection between PISA results and policy is not always obvious. The supranational spell of PISA in policy is in the way that PISA results are used as a magic wand in political rhetoric, as though they conjure particular policy choices. This serves as a distraction from the ideological basis for reforms. The same PISA results could motivate a range of different policy solutions.  相似文献

This longitudinal study tested the role of children's appraisals of threat and self-blame as mediators of the association between interparental conflict and child adjustment in a sample of 298 Welsh children ages 11 to 12 years. Exposure to higher levels of interparental conflict at Time 1 predicted greater perceived threat and self-blame at Time 2, after accounting for the effects of Time 1 adjustment and appraisals on later appraisals. Perceived threat in turn was associated with increased internalizing problems at Tune 2, and self-blame was associated with higher externalizing problems. The pattern of results was largely consistent for child and parent reports of conflict and for boys and girls, though some gender differences were found in associations between appraisals and adjustment.  相似文献

The ability to deliver sufficient core anatomical knowledge and understanding to medical students with limited time and resources remains a major challenge for anatomy educators. Here, we report the results of switching from a primarily didactic method of teaching to supported self-directed learning for students studying anatomy as part of undergraduate medicine at the University of Edinburgh. The supported self-directed approach we have developed makes use of an integrated range of resources, including formal lectures and practical sessions (incorporating gross anatomy specimens, medical imaging technologies, anatomical models, clinical scenarios, and surface anatomy workstations). In practical sessions, students are provided with a custom-made workbook that guides them through each session, with academic staff, postgraduate tutors, and near-peer teaching assistants present to deal with misunderstandings and explain more complicated topics. This approach retains many of the best attributes of didactic teaching but blends them with the advantages associated with self-directed learning approaches. The switch to supported self-directed learning-initially introduced in 2005-resulted in a significant improvement in anatomy examination scores over the subsequent period of five years, manifesting as an increase in the average anatomy practical spot examination mark, less students failing to obtain the pass mark and more students passing with distinction. We conclude that the introduction of supported self-directed learning improved students' engagement, leading to deeper learning and better understanding and knowledge of anatomy.  相似文献

In the United Kingdom the topic of the comparability of academicqualifications features prominently on the agenda in higher education. The papersummarises the debate and highlights key issues. It offers specific reflections on theexperience of one university as it seeks to address the topic of postgraduate qualifications,disentangle the many strands of a complex and multi-faceted set of questions and furtherstrengthen internal quality processes in order to meet the growing demands by external bodiesand interest groups.  相似文献

The purpose of this research was to determine to what extent human performance technology (HPT) is being taught in academic programs that traditionally emphasized training—programs such as instructional systems, training and development, human resource development, and adult learning. A written survey was used to collect data from 82 academic programs. Results indicate that while training (and the related areas of needs assessment and evaluation) continues to dominate curricula at these institutions, non-training performance improvement strategies (and the broader performance analysis that leads to their selection) are frequently taught as well. No correlations were found between the extent of teaching HPT topics and the variables of program size, program type, location, degrees offered, or faculty membership in NSPI (now called the International Society for Performance Improvement). Future research could investigate the driving and restraining forces that determine HPT's impact on the curriculum and the effects that current curricula have on program graduates.  相似文献

Parenting and children's temperament are important influences on language development. However, temperament may reflect prior parenting, and parenting effects may reflect genes common to parents and children. In 561 U.S. adoptees (57% male) and their birth and rearing parents (70% and 92% White, 13% and 4% African American, and 7% and 2% Latinx, respectively), this study demonstrated how genetic propensity for temperament affects language development, and how this relates to parenting. Genetic propensity for negative emotionality inversely predicted language at 27 months (β = −.15) and evoked greater maternal warmth (β = .12), whereas propensity for surgency positively predicted language at 4.5 years (β = .20), especially when warmth was low. Parental warmth (β = .15) and sensitivity (β = .19) further contributed to language development, controlling for common gene effects.  相似文献

This paper seeks to identify and model the key parameters which impact on the commercial performance of a specialist, technology focused, early-stage, venture capital fund. Using both input (costs) and output (expected values) data provided by a number of specialist, independent venture capital firms, a spreadsheet model of a 10 year term fund is developed. These figures are used to generate Internal Rate of Return (IRR) and Net Present Value (NPV) performance calculations for the investment commitments of both the institutional, limited partners and venture capitalist, general partner. The generically defined model allows the user to address both conceptual and pragmatic questions regarding the relationship between fund structure and performance. The model is further developed to determine the effect on fund performance of two venture capital related, ‘indirect' State support schemes (guarantee and leverage options). Iterative interrogations of the model demonstrate the sensitivity of economic returns to the scale of the investment activity. State supported schemes mitigate but do not remove the negative performance consequences of small fund size. A fund with under £15 million (US$25 million or ECU21 million) under management is of increasing economic vulnerability.  相似文献
