Gina Conti-Ramsden Emma Knox Nicola Botting & Zoë Simkin 《British Journal of Special Education》2002,29(2):76-82
As part of their longitudinal investigations of a large cohort with a history of specific language impairment (SLI), Professor Gina Conti-Ramsden and her research team based at the School of Education, University of Manchester, Dr Emma Knox, Dr Nicola Botting and Dr Zoë Simkin report on the changing educational placements and National Curriculum assessment outcomes of 200 children at 11 years. Teacher questionnaires reporting on the Year 6 primary education placements of the sample reveal details about the long-term educational needs of children with SLI.
Furthermore, in exploring the experiences of the sample in the National Curriculum Key Stage 2 tests the present study found that children with SLI perform poorly relative to national expectations of levels of achievement across all tests. At present there are no guidelines for supporting children with SLI in relation to National Curriculum tests and the present data suggests there is an obvious need for these to be developed. 相似文献

At-risk families’ control style (autonomy support and coercive control) was examined in relation to children's school readiness; children's social skills and mastery motivation were hypothesized mediating variables. In two different, low-income samples from diverse ethnic backgrounds, one preschool sample recruited from Head Start (N = 199) and a school transition sample composed of children entering elementary school (N = 344), parental control styles were related to children's academic readiness modestly but significantly in the preschool sample and weakly in the school transition sample. Children's social skills and mastery motivation skills (persistence and goal orientation) were significantly related to the academic measures of school readiness, and fully mediated the association between parents’ use of coercive behavioral control and academic readiness. Such mediation could not be tested for parental support of children's autonomy. The results indicate that a developmental cascade exists between parental control strategies and academic indices of school readiness, emphasizing the importance of family context models of school readiness. Furthermore, strong correlations between the domains of school readiness were found in both samples, reinforcing calls for a multidimensional approach to supporting school readiness in early childhood education programs. 相似文献

An hybrid uninterrupted multi-speed transmission (HUMST), based on the integration of a planetary gear set and a 3-speed automatic manual transmission (3-AMT), is developed to satisfy the specific performance indexes of mining trucks. The power-split device can alleviate and eliminate the inherent torque interruption of the 3-AMT during gear shift by implementing the designed cooperative shift control strategy which is optimized by quadratic performance index. In order to achieve fast torque coordination while guaranteeing the driving comfort performance, the torque profiles of the power split device and the traction motor are optimized by Linear-quadratic regulator (LQR) algorithm. Dynamic programming (DP) is implemented as a benchmark to demonstrate the maximum fuel efficiency of the proposed HUMST. Because of the high computational cost of optimal control strategies such as DP, an improved real-time control strategy (IRTCS) using modified Gaussian distribution function is proposed to significantly reduce the computing load. As efficiency-oriented energy control strategy would result in frequent gear shifts, to achieve a desirable tradeoff between the overall efficiency and the shift stability, multi-objective genetic algorithm (MGA) is integrated to optimize the overall performance. The detail mathematical and dynamic model shows that the proposed shifting strategy with LQR can effectively suppress shift jerk, and the proposed IRTCS with MGA can reduce shift frequency by 70.78% to improve the drivability, only sacrificing 4.86% of overall efficiency compared to that of DP. 相似文献

This study evaluated the interpersonal sensitivity of third culture individuals, defined as people who lived in a country other than that of their nationality during their developmental years, by comparing them to mono-cultured individuals. While the notion that third culture individuals develop enhanced perceptual skills as a result of intercultural adaptation is widely accepted in popular and professional literature, this assertion has not been empirically tested. Previous research on intercultural communication competence and adaptation has almost exclusively focused on intercultural exposure among adults. This study collected data from 142 individuals using web-based surveys. The instruments measured two aspects of participants’ interpersonal sensitivity: social and emotional sensitivity. Results showed that third culture individuals have significantly higher social sensitivity than mono-cultured individuals, while mono-cultured individuals reported higher emotional sensitivity. Additionally, no significant correlation was found between greater intercultural experience and increased interpersonal sensitivity. 相似文献

This phenomenological study, based on ecological systems theory, examined the college student bereavement experience in a Christian university. Undergraduate students (N = 127) from a small Christian university provided answers to open‐ended questions about their experiences regarding college following a death loss. Results indicate that students are generally successful in adapting to bereavement and prefer an environment open to discussing death and asking difficult religious questions. Implications for counselors are provided. 相似文献

In this study, we identified 10 sexuality education programmes from different locations in the USA that aim to give young people knowledge and skills to develop healthy relationships, as well as avoid pregnancy and disease. We conducted in-depth interviews with programme administrators to develop a series of case studies and provide concrete recommendations for education and public health professionals to implement similar approaches in their communities. Many programme administrators succeeded in developing partnerships, adapting existing curricula to suit their environments, engaging external evaluators and garnering support from teachers and parents. However, few programme developers conducted formal needs assessments before developing programmes and many struggled to implement curricula with fidelity and to employ rigorous evaluation designs. Nearly all participants identified concerns over funding as a threat to sustainability. We conclude that schools and organisations need technical assistance to build capacity for rigorous programme planning, implementation and evaluation, as well as additional funding streams to support emerging programmes. 相似文献

This study reports on a very successful collaboration between teacher education courses in Manchester and Amsterdam and the Van Gogh Museum in Amsterdam. The central aim of the initiative was to promote and sustain partnerships between Higher Education (HE) institutions, public galleries and schools with a view to developing, delivering and sharing good practice in art and design within a European context. 相似文献

In this paper we review arguments that have been well rehearsed in the economic literature in the past twenty years and which are relevant to the present debate over student loans and the funding of the higher education sector.
The body of the paper assesses four finding proposals: (1) The Government's mortgage-type loan scheme, (2) The Barr, National Insurance repayment scheme, (3) The Graduate Tax and (4) A Loan scheme based on the individual higher education institution.
Each proposal is assessed in terms of its efficiency impact in six dimensions, (i) set up costs and flexibility, (ii) administrative costs (iii) incentives (iv) information (v) the balance of public and private involvement, and (vi) equity.
We conclude that, overall, we would not recommend any of the alternatives as unambiguously superior on all counts. Insofar as a radical approach is to be implemented we argue that a scheme based on the individual higher education institution, with repayment via the National Insurance system, is probably the best option. 相似文献
