Netcourses—courses delivered primarily over digital networks—promise to provide learners with quality, low-cost learning opportunities anywhere and anytime. While having implications throughout education, adult professionals may be the first to make extensive use of netcourses. By increasing the quality and timeliness of teacher professional development while reducing its costs, netcourses could have a major impact on the quality of teaching. In order to understand the realities of this promise, we have reviewed in detail all netcourses for teachers in mathematics and science. As a result of this analysis, we have developed new designs for the effective use of this medium with mathematics and science teachers. 相似文献

This research compares the industry readiness, product development skill level, and overall knowledge gains of students taking an undergraduate research course (treatment) to those who did not (control). This 2‐semester Applied Interdisciplinary Product Development (AIPD) course for sophomores brought together interdisciplinary teams of food science, nutrition, and packaging science students in a hands‐on setting to create healthy food products for children, complete with retail packaging. A Subject Knowledge Assessment (SKA) was used to evaluate the mean percent difference value (MPDV) of food science, nutrition, packaging science, and general product development knowledge gained through the course. SKA results indicated that the MPDV were significantly different (α = 0.05) between the treatment and comparison groups in the overall score and in every subject area score except packaging science. Data from an Exit Questionnaire (EQ) was used for evaluation of attitudes pertaining to product development knowledge and skills, department engagement, and pedagogy. EQ results indicated that mean scores between the treatment and comparison groups were significantly different (α = 0.05) in 7 of the 9 statements on product development knowledge and skills, both statements pertaining to pedagogy, and the statement pertaining to department engagement. Overall, the research project was considered a successful intervention for educating sophomores at the University. Overall, the research project was considered a successful intervention for educating sophomores in the Food, Nutrition and Packaging Science department at Clemson University. The student‐lead teams were held to a greater degree of accountability for their success in terms of education gleaned and value of experience gained as metric for the University and other IFT Accredited programs. 相似文献

Understanding what teachers need to be more comfortable and confident in their profession is crucial to the future of effective teachers and scientific literacy in public schools. This study focuses on the experiences of Arizona biology teachers in teaching evolution, using a clinical model of stress to identify sources of pressure, the resulting stresses, and coping strategies they employ to alleviate these stresses. We conducted focus groups, one‐on‐one interviews, and written surveys with 15 biology teachers from the Phoenix area. On the basis of their responses, teachers were clustered into three categories: “Conflicted,” who struggle with their own beliefs and the possible impact of their teaching, “Selective,” who carefully avoid difficult topics and situations, and “Scientists,” who see no place for controversial social issues in their science classroom. Teachers from each group felt that they could be more effective in teaching evolution if they possessed the most up‐to‐date information about evolution and genomics, a safe space in which to reflect on the possible social and personal implications with their peers, and access to richer lesson plans for teaching evolution that include not only science but personal stories regarding how the lessons arose, and what problems and opportunities they created. © 2004 Wiley Periodicals, Inc.

Building from the concept ‘sponsors of literacy', the authors revisit three empirical studies to argue for mobilising notions of sponsorship beyond fixed conceptions of individual sponsors and literacy to lifewide perspectives that take into account sponsoring relations across the broader learning lives of youth. The authors take up the theoretical heuristic ‘sponsorscapes' as a lens for attending to the dynamically networked, reciprocal and human‐material dimensions of literacy practices. With cases drawn from across settings and research foci, including middle school students in a classroom setting, high school‐aged youth across contexts and a participant‐researcher's interactions with a college student, the authors argue that attending to sponsorscapes can contribute critical insight into the emergent, diverse and valued literacies and sponsorship thriving across lifewide learning pathways, while recognising learners' agentive roles in investing, resisting and sponsoring literacies. 相似文献

Opportunities are increasing for students with intellectual and/or developmental disabilities to attend postsecondary education programs located at college campuses around the nation. Students who attend postsecondary education programs experience numerous positive outcomes, including independent living skills and expanded social networks. However, although parent‐professional partnerships could significantly enhance long‐term outcomes such as competitive employment and independent living, there is a paucity of information about the nature of these partnerships in postsecondary settings. The purpose of this expository article is to describe how staff from a midwestern postsecondary education program facilitate parent‐professional partnerships through parent involvement and support. 相似文献

ABSTRACTHigher education is understood as essential to enabling social mobility. Research and policy have centred on access to university, but recently attention has turned to the journey of social mobility itself – and its costs. Long-distance or ‘extreme’ social mobility journeys particularly require analysis. This paper examines journeys of first-in-family university students in the especially high-status degree of medicine, through interviews with 21 students at an Australian medical school. Three themes are discussed: (1) the roots of participants’ social mobility journeys; (2) how sociocultural difference is experienced and negotiated within medical school; and (3) how participants think about their professional identities and futures. Students described getting to medical school ‘the hard way’, and emphasised the different backgrounds and attitudes of themselves and their wealthier peers. Many felt like ‘imposters’, using self-deprecating language to highlight their lack of ‘fit’ in the privileged world of medicine. However, such language also reflected resistance to middle-class norms and served to create solidarity with community of origin, and, importantly, patients. Rather than narratives of loss, students’ stories reflect a tactical refinement of self and incorporation of certain middle-class attributes, alongside an appreciation of the worth their ‘difference’ brings to their new destination, the medical profession. 相似文献

ABSTRACT Clark and Murray examine the six Critical Performance Factors for Mega planning in an example drawn from the five‐year history of the population program of a major west coast philanthropy. In this article, the authors describe the salience and scope of the population issue as it is relates to other global trends; the steps the foundation took to “scope” the program and establish measurable impacts. It rates performance against the critical factors, then looks at some specific country impacts five years later. This analysis will be incorporated into the plan revision. Summary and What Next Indications are that our funding and the work of the grantees are having good impact in the country programs. Systematic, comprehensive reviews involving outside/inside experts, quantitative and qualitative data will be completed in all five country programs by mid‐2005. Also in 2005, the Board will work with staff and outside experts to examine the results of grant making and review and discuss our long term, overall approach. Much has changed since 1998. We will review those changes and see if any longer term shifts in funding emphasis will be appropriate. This effort to refresh our strategic thinking will allow us to revise, as appropriate, the stated missions of the population work, its assumptions, and how it fits into the overall work and goals of the Foundation. 相似文献

This study investigated reasons for the omission of the torso typical in most young children's drawings of the human figure. Do they have an incomplete mental image of the human figure; if so will the torso be omitted from a manikin task too? As the head is normally drawn first, is the torso simply forgotten; if so will children include it if they are asked to draw the torso first? Eighty tadpole‐drawers (aged between 2 years 7 months and 5 years) were randomly allocated to a drawing or a manikin condition; they were further subdivided into a head‐first or torso‐first condition. Significantly more children produced a conventional figure when they constructed a manikin compared with those who were asked to draw; the order of body parts (head‐first vs torso‐first) had no significant effect. These results suggest that young children omit the torso from their human figures because they have yet to devise a way of drawing it, perhaps because it is a relatively unimportant item; there is little evidence that they have simply forgotten it or that their mental model for the human figure is incomplete. 相似文献

We apply the comparative techniques originated by Wolpin, K.I. (1977, Education and screening, American Economic Review, 67, 949–958) and Psacharopoulos (1979, On the weak versus the strong version of the screening hypothesis, Economics Letters, 4, 181–185) to discriminate between the ‘weak' and ‘strong' screening hypotheses. Controlling for sample selection, we find evidence for weak but not strong screening in the Italian labour market. [JEL J3, J24, J41] 相似文献
