Foster EM 《Child development》2002,73(6):1904-1914
Research in child development reveals that the sources, level, stability, and uses of family resources have a profound effect on children's well-being and long-term outcomes. Although that research has incorporated economic constructs and measures, developmentalists generally ignore the formal economic framework for thinking about family resources and child outcomes. Building on the premise that children are an investment, that framework explains how families allocate resources and links that decision to other family choices and to key child outcomes, such as schooling, morbidity, and mortality among others. This article explains economists' general approach to family behavior (the so-called theory of household production) and then describes how that framework is useful for thinking about families and children. The article then outlines how economists model parental investment in children and examines the implications of that approach for developmental science. This discussion is illustrated using an example of interest to developmentalists--the involvement of children and adolescents in after-school activities. A concluding section discusses the benefits of and potential barriers to collaboration between economists and developmentalists. 相似文献

This article reports an undergraduate software engineering project in which, over a period of 2 years, four student teams from different cohorts developed a note-taking app for four academic clients at the students’ own university. We investigated how projects involving internal clients can give students the benefits of engaging in real software development while also giving them experience of a student-staff collaboration that has its own benefits for students, academics, and the university more broadly. As the university involved is a Sino-Foreign university located in China, where most students are Chinese and most teaching staff are not, this ‘student as co-producer’ approach interacts with another feature of the project: cultural distance. Based on analysis of notes, reports, interviews, and focus groups, we recommend that students should be provided with communicative strategies for dealing with academics as clients; universities should develop policies on ownership of student-staff collaborations; and projects should include a formalised handover process. This article can serve as guidance for educators considering a ‘students as co-producers’ approach for software development projects. 相似文献

Video games have become an essential part of the way people play and learn. While an increasing number of people are using games to learn in informal environments, their acceptance in the classroom as an instructional activity has been mixed. Successes in informal learning have caused supporters to falsely believe that implementing them into the classroom would be a relatively easy transition and have the potential to revolutionise the entire educational system. In spite of all the hype, many are puzzled as to why more teachers have not yet incorporated them into their teaching. The literature is littered with reports that point to a variety of reasons. One of the reasons, we believe, is that very little has been done to convince teachers that the effort to change their curriculum to integrate video games and other forms of technology is worthy of the effort. Not until policy makers realise the importance of professional development and training as an important use of funds will positive changes in thinking and perceptions come about, which will allow these various forms of technology to reach their potential. The authors have hypothesised that the major impediments to useful technology integration include the general lack of institutional infrastructure, poor teacher training, and overly‐complicated technologies. Overcoming these obstacles requires both a top‐down and a bottom‐up approach. This paper presents the results of a pilot study with a group of preservice teachers to determine whether our hypotheses regarding potential negativity surrounding video games was valid and whether a wider scale study is warranted. The results of this study are discussed along with suggestions for further research and potential changes in teacher training programmes. 相似文献

AbstractIn this article we investigate the effectiveness of learning analytics for identifying at-risk students in higher education institutions using data output from an in-situ learning analytics platform. Amongst other things, the platform generates ‘no-engagement’ alerts if students have not engaged with any of the data sources measured for 14 consecutive days. We tested the relationship between these alerts and student outcomes for two cohorts of first-year undergraduate students. We also compared the efficiency of using these alerts to identify students at risk of poorer outcomes with the efficiency of using demographic data, using widening participation status as a case study example. The no-engagement alerts were found to be more efficient at spotting students not progressing and not attaining than demographic data. In order to investigate the efficacy of learning analytics for addressing differential student outcomes for disadvantaged groups, the team also analysed the likelihood of students with widening participation status generating alerts compared with their non-widening participation counterparts. The odds of students with widening participation status generating an alert were on average 43% higher, demonstrating the potential of such a system to preferentially target support at disadvantaged groups without needing to target directly based on immutable factors such as their socio-economic background. 相似文献

The author traces the historical development of standards for library services prepared by the Joint Commission on Accreditation of Hospitals, emphasizing those elements of the present standards that auger well for the development of libraries in hospitals. Then examined are the role of librarians and new roles for libraries, stressing sound management practices that ensure continued development. 相似文献

Walking is a safe, accessible and low cost activity, amenable to change and known to have great potential to increase physical activity levels in sedentary individuals. The objective of this study is to estimate the proportion of the 2009 adult population of England who would attain or exceed vigorous intensity activity (>70% maximum heart rate [HR(max)]) by walking at 3 mph. We conducted predictive impact modelling using participants' (n = 1741, aged 25-64 years) cardiovascular fitness data from treadmill walking tests. We combined this data with English population estimates adjusted for age and sex to estimate the numbers of individuals that would exceed 70% HR(max) (an intensity considered sufficient for fitness gains) when walking at 3 mph (4.8 km · h(-1)). We estimate 1.5 million men (95% confidence interval [CI] 0.9-2.2 million) (from 13.4 million corresponding to 11.6% (95% CI 7.0-16.2%)) and 3.9 million women (95% CI 3.0-4.8 million) (from 13.6 million corresponding to 28.6% (95% CI 22.0-35.1%)) in England aged 25-64 years would benefit from regularly walking at 3 mph. In total, a projected 5.4 million individuals (95% CI 3.9-6.9 million) aged 25-64 (from 26.97 million corresponding to 20.1% (95% CI 14.6-25.7%)) could benefit from walking at 3 mph. Our estimates suggest a considerable number of individuals in the English population could receive fitness and health benefits by walking regularly at 3 mph. Physical activity messages that promote walking at this speed may therefore have the potential to significantly impact national fitness levels and health in England. 相似文献

Although breaking down a mathematical problem into smaller parts can often be an effective solution strategy, when the same reductionist approach is applied to mathematics pedagogy the effects are far from beneficial for students. Mathematics pedagogy in UK schools is gaining an increasingly reductionist flavour, as seen in an excessive focus on bite-sized learning objectives and a tendency for mathematics teachers to path-smooth their students’ learning. I argue that a reductionist mathematics pedagogy severely restricts students’ opportunities to engage in authentic mathematical thinking and deprives them of the enjoyment of solving richer, more worthwhile problems, which would forge connections across diverse areas of the subject. I attribute the rise of a reductionist mathematics pedagogy partly to an assessment-dominated curriculum and partly to a systemic de-professionalisation of teachers through a performative accountability culture in which they are constantly required to prove to non-specialist managers that they are effective. I argue that pedagogical reductionism in mathematics must be resisted in favour of a more holistic approach, in which students are able to bring a variety of mathematical knowledge and skills to bear on rich, challenging and non-routine mathematical tasks. Some principles for achieving this are outlined and some examples are given. 相似文献

This paper offers an emerging interpretive framework for understanding the active role instructional designers play in the transformation of learning systems in higher education. A 3-year study of instructional designers in Canadian universities revealed how, through reflexive critical practice, designers are active, moral, political, and influential in activating change at interpersonal, professional, institutional and societal levels. Through narrative inquiry the voices of designers reflect the scope of agency, community and relational practice in which they regularly engage with faculty in institutions of higher learning.

As a basis for thoughts on the roles of reference books and computerized information services in general, a comparison is made of the value to medical libraries of a comprehensive reference tool (the new dual media publication Biomedical Research in Progress) and a comprehensive information center file (the Smithsonian Science Information Exchange, the national resource for information on research in progress). It is concluded that a detailed reference tool which is physically present for library users has several advantages, in particular the provision of both detailed and comprehensive retrieval of all biomedical research information at substantially less annual cost and with faster access time than is possible with comparable questions put to an information center. On the other hand, the information center is able to provide more up-to-date material in more flexible combinations. The recommendation is made that medical libraries avoid treating the comprehensive reference tool and the computerized information file as alternatives and instead view both as necessary and complementary to each other. 相似文献
