Assisted conception is becoming an increasingly more common treatment option for women and couples who experience fertility problems. Links have been made in the literature between assisted conception and a greater incidence of pregnancy or birth complications, low birth weight or premature babies, and babies with congenital abnormalities. In addition, evidence suggests that the experience of assisted conception may influence the development of early mothering relationships and impact parenting adjustment. Although this commentary article does not strategically review all available literature, it provides an overview of the health issues that women and families undergoing assisted conception have experienced or may experience. Through raising awareness and promoting discussion of these issues, practitioners will be better equipped to provide informed education and support.  相似文献

The problems of shifting from norm-referenced assessment to criterion-referenced assessment have been identified by several scholars in recent years. These important critiques touch on a number of areas, but neglect a key question about how assessors learn to accomplish what Shay calls a ‘socially situated interpretive act'. Research that does exist tends to focus on salaried, full-time academics. This overlooks the heterogeneity of the academic labour force in higher education and the substantial contribution made by contract (hourly-paid) lecturers, particularly in applied disciplines such as Business and Management. This study explores how nine newcomers to a UK Business School – including salaried and contract staff – attempt to understand local assessment practice. We use a situated learning lens to analyse their diary entries and interviews about their experiences of learning to mark. Drawing on scholars such as Sadler, we examine the suggestion that exemplars are important for newcomers coming to understand local assessment practice. We argue for the fundamental importance of dialogue about exemplars and other aspects of practice, both to develop inter-subject understandings of assessment ‘anchor points' and also to foster among newcomers (and especially contract lecturers) a greater sense of participating in, and being valued by, the local assessment community.  相似文献

This paper describes an ongoing process of participatory curriculum development. It outlines some of the tensions which need to be explored in science curriculum development: debates about the nature of science, of society, of school science content and of learning theories. The process whereby action can arise from this debate is also explored. An example will be outlined of a network of science curriculum action which has developed from the work of a range of science education projects in Natal, South Africa. Specializations: science curriculum development from primary to tertiary level. Specializations: inservice primary science teacher development. Specializations: inservice teacher development, biology education. Specializations: environmental education, teacher development. Specializations: environmental education, teacher development.  相似文献

The media analysis is situated in the larger body of studies that explore the varied reasons why different policy actors advocate for international large-scale student assessments (ILSAs) and adds to the research on the fast advance of the global education industry. The analysis of The Economist, Financial Times, and Wall Street Journal covers publications on ‘PISA’, ‘TIMSS’, and related search items over the period 1996–2016. The three media outlets vary in terms of ILSA reporting. The Economist and Financial Times tend to focus on PISA, whereas the Wall Street Journal pays greater attention to TIMSS than PISA. The content analysis of 59 articles yields interesting results about how the business-oriented readership of the three media outlets frames public education and why it sees education as a profitable business opportunity. The three most common narratives, reflecting the business logic, are the following: (i) public education is in crisis; (ii) there is no correlation between spending and education outcome; and (iii) school accountability, teacher performance, and decentralisation represent the most effective policies to improve the quality of education. Drawing on these three common narratives, the financial media outlets present a particular vision of how to improve education; a vision in which the private sector is supposed to play a major role.  相似文献

Young women do not choose to be engineers nearly as often as young men, and they tend to cluster in particular specialties when they do. We examine these patterns and the role of gender schemas as applied to perceptions of typical engineers in understanding the choices that women make in terms of engineering specialties. We use Part 1 of two waves of survey data collected from first-year engineering students at a large Midwestern university in the fall of 2014. Respondents scored typical engineers on 60 items from the Bem Sex-Role Inventory [Bem, S. L. 1974. “The Measurement of Psychological Androgyny.” Journal of Consulting and Clinical Psychology 42: 155–162]. Preliminary results show that women consider the typical engineer to be more masculine compared to the impressions gathered from men. Additionally, engineering gender schemas predict some specialty areas but not all, suggesting that gendered perceptions may not affect choice of specialty. Our results provide insight into the decisions that women make once entering engineering.  相似文献

Duff, Mengoni, Bailey and Snowling (Journal of Research in Reading, 38: 109–123; 2015) evaluated the sensitivity and specificity of the phonics screening check against two reference standards. This report aims to correct a minor data error in the original article and to present further analysis of the data. The methods used are calculation of predictive values of the phonics screening check in addition to sensitivity and specificity, and evaluation of agreement between the reference tests. Predictive values are important indicators of screening test quality. The positive predictive value of the phonics check is low (0.31) when compared with a standardised reading test but high (0.84) when compared with teachers' phonic phases judgements, reflecting poor agreement (kappa = 0.27) between reference tests. Results have implications for practice in terms of choice of reference standard and choice of threshold criterion for children to pass the screening check. Longitudinal data are needed to assess the predictive validity and utility of the check. What is already known about this topic:
  • The importance of phonics in learning to read is widely acknowledged.
  • The phonics screening check was introduced into U.K. schools in 2012 to ensure that all children develop phonic decoding skills.
  • Estimates of the sensitivity and specificity of the phonics screening check, compared with two established ‘reference’ measures, were reported by Duff et al. ( 2015 ).
What this paper adds:
  • We correct a minor error in the report of the original data by Duff et al. ( 2015 ).
  • We draw attention to the importance of including predictive values, alongside sensitivity and specificity, in the evaluation of screening test validity. We also propose an alternative statistic for comparing the two reference measures.
  • We show that applying this further analysis to the data in Duff et al. ( 2015 ) reveals the following: (i) the numbers of incorrect (false positive and false negative) outcomes in the phonics check and (ii) the marked difference in these numbers depending on the choice of reference measure.
Implications for theory, policy or practice:
  • Reports of screening test validity should include positive and negative predictive values.
  • A fundamental consideration for evaluating the validity of the phonics screening check is the choice of reference measure.
  • Longitudinal data are needed to assess the predictive validity and utility of the phonics check.

Higher education has seen increasing educational mobility as students finance themselves or get financial support from their families to study abroad (Shields Comp Educ Rev 57(4):609–636, 2013; Verbik and Lazanowski in World education news and reviews. http://www.wes.org/educators/pdf/StudentMobility.pdf, 2007). Another significant source of support, particularly for students in developing countries, is that from international aid scholarships. This research presents the reported experiences of 15 Tongan postgraduate scholars who successfully completed overseas postgraduate studies. The study focuses on the perceptions of qualifications and of scholars, as well as knowledge utilisation and knowledge resituation in and beyond the workplace. Knowledge utilisation, sometimes referred to as knowledge management, is how others support returnees’ to share and make use of their knowledge; while knowledge resituation is a personal and individual process in which knowledge gained in one context is tuned to and made use of in a new context (Eraut in Expertise development: the transition between school and work. Open Universiteit, Heerlen, pp 52–73, 2004a, Pedagogy and practice. Culture and identities. Sage, London, 2008; Franken 2012). Given the challenges the scholars faced, we advocate for a more explicit recognition of what knowledge and skills returning scholars bring home, and a more proactive and strategic use of these by their workplaces in particular.  相似文献

Despite the importance of early writing development to children’s school success, research documents that early childhood teachers spend little time actively supporting children’s writing development in preschool classrooms. This article provides a framework for integrating writing experiences across the early childhood curriculum. Practical examples are given regarding how writing opportunities can be incorporated into existing activities and play settings. The metaphor of backgrounding and foregrounding writing experiences is used to illustrate ways that teachers can set writing rich environments and activities in a manner that makes it easier for teachers to bring these experiences into everyday learning opportunities. Attention is given to how teachers can bring writing to the foreground of the curriculum by drawing attention to writing materials, making natural connections with children’s interest and play, and scaffolding children’s early writing attempts and experiences.  相似文献

Postgraduate students' choice of university, and related mobility issues, have been of interest to Australian university researchers, supervisors and administrators for some time. However, with the release of the Commonwealth Government's 1999 Green Paper on research and research training, which proposes greater portability of research student funding, a sense of urgency regarding these issues has developed. This paper reports on students' choice of a particular university for postgraduate research and on what information they made those decisions. A survey was conducted in 1997 of 938 applicants for Postgraduate Research Scholarships to Flinders University, Macquarie University and the Universities of Western Australia, Adelaide and Melbourne. The survey sought to identify respondents' choices and possible movement to undertake research awards. Questions dealt with a wide range of issues with a particular focus on sources used to access information on higher degrees, preference(s) for where they wished to study, factors leading to their preferred choice, and influences on the decision to move or not move to another institution. Approximately 50% of respondents were younger than 25 years and only 27% were living with their parents. An Honour's degree was the most common prior qualification for students (73%), but only 61% were enrolling directly from their previous degree. Thirty-six per cent reported that they regularly read their main local paper for information related to postgraduate research opportunities and 39% of respondents did not regularly access any source of media for postgraduate information. Forty-two per cent of students did not explore any opportunities at other universities prior to making their decision about enrolment. Almost all students who were planning to enrol at the same university were remaining in the same department. Commensurate with this, 73% reported that their Honour's supervisor or academic staff in their original university were their major source of information on study destinations. These results provide baseline data, which can be used to approach the issue of postgraduate mobility more strategically.  相似文献

Most research focuses on preschoolers’ primary non-parental child care arrangement despite evidence that multiple arrangements are relatively common. Using the nationally-representative Early Childhood Longitudinal Study, Birth Cohort, we compare characteristics and outcomes of families whose 4-year olds attend both home- and center-based child care with those who attend either home- or center-based care exclusively or receive no non-parental care at all. We find that about one fifth of 4-year olds attend both home- and center-based child care. Mothers’ priorities for care (getting their child ready for school, matching their families’ cultural background) and perceptions of good local care options predict their combining home- and center-based care. Preschoolers score higher on reading and math assessments, on average, when they attend centers, alone or in combination with home-based child care, than when they are cared for only in homes, either by their parents or by others. Preschoolers’ average socioemotional outcomes generally do not differ between families who do and who do not combine care types. Implications for research and policy are discussed.  相似文献
