2006年8月,GEN(I网络创新的全球化环境)项目组公布其项目的设计原则。来自普林斯顿大学、麻省理工大学、华盛顿大学等学校的十二位专家编写了这份报告。该报告阐述了GENI的研究范围、用户的需求、需求的内在压力,以及工程设计的原则。报告指出了GENI的价值主张,广泛的部署、多样化可扩展的网络技术集合、对真实用户流量的支持仍是GENI关注的原则和方向。上期已经介绍第一部分——“分布式需求定义GENI的重心”,本期刊出第二部分——“解决分布式需求的内在冲突”。 相似文献

The development of extensive and authentic teacher evaluation raises questions about how best to organize and present the increased amount and variety of assessment materials. Portfolios have been suggested for teacher evaluation because they are well suited to capture the complexities of teaching. However, portfolios 1) are difficult to judge, 2) are difficult to archive, 3) lack key information, 4) miss excellent teachers with simple materials, 5) rarely plan for audiences, 6) distort when required, and 7) bring conflicts of interest. Teacher dossiers are compressed collections of objective data which are easier to judge, demonstrably reliable, and cost-effective. 相似文献

The present study produced an empirically derived, developmental continuum of children's understanding of specific pains. Subjects of 5 age groups: preschool (ages 3-4), first grade (ages 6-7), third grade (ages 8-10), sixth grade (ages 11-12) and college freshmen (ages 18-23) were interviewed with open-ended questions. The subjects were questioned extensively about 3 specific types of pain: an injury (skinned knee), a medical intervention (injection), and an illness (headache). Subjects were asked to describe each pain, tell why the pain hurt, and state the value of the pain. Their answers were then categorized and the categories ordered developmentally by experts in pediatric pain who were unaware of the children's ages. Then children's specific answers were given developmental scores. Multivariate analyses revealed that older children had more complex and precise understandings of pain, and this pattern differed by type of pain and by aspect of pain being considered. The subjects were also asked to report the frequency of their own pains and their parents' pain; parental and self-reported pains were closely related. 相似文献

The development of positive justice reasoning in profoundly deaf, signing Australian 7- to 12-year-olds and hearing children was compared. Reactions to cognitive conflict were also assessed. The performance of those deaf children whose signed English skills were adequate to give detailed justifications for reward allocation was examined separately. The deaf children were delayed relative to hearing children in number and liquid conservation, but equally mature in justice reasoning. Spontaneous conflicts with signing peers over sharing possessions conceivably could be responsible for the fluently signing deaf children's development of positive justice reasoning on pace with their normally-hearing counterparts. Experimentally-induced conflict resulted in progress for the hearing but not the deaf children. Results are discussed in relation to factors that promote deaf children's tolerance for ambiguity (Brice, 1985) and impede their resolution of cognitive conflict (Liben, 1978). 相似文献

What can be learned about assessment from what educators in the creative practices focus their studio publications on? What should form the focus of assessment in architecture, art and design studios? In this article we draw on 118 journal articles on studio published over the last decade in three disciplines; architecture, art and design to inform the focus of studio assessment. We believe that what is published by educators themselves in these disciplines reveals what matters most to them. In addition, we argue that regardless of the primary emphasis placed in each discipline, assessment in studio should encompass a broad set of indicators. Within the wider literature including in architecture, art and design, a view of assessment is emerging that recognises the process and the person, beyond a view that positions the product or art/design arte‐fact above all else. Therefore, drawing on what educators in architecture, art and design mentioned most in the journal publications analysed, as well as the literature on good assessment, we offer a holistic model to guide and take studio assessment in the creative disciplines further. 相似文献

An interactive videodisc system designed to teach language concepts to deaf students was evaluated in a classroom trial. An experimental group of 18 students spent 60 twenty‐minute sessions over a five‐month period learning language concepts by interacting with the system while a control group of 16 students learned the same concepts in their regular classroom setting. Both groups made significant progress from pre‐ to post‐test on two criterion‐referenced testsdeveloped by project staff. Experimental students were enthusiastic about the videodisc, felt that their language skills had improved, and were anxious to continue working with the system. 相似文献

Student teaching (guided teaching by a prospective teacher under the supervision of an experienced “cooperating” teacher)
provides an important opportunity for prospective teachers to increase their understanding of mathematics in and for teaching.
The interactions between a student teacher and cooperating teacher provide an obvious mechanism for such learning to occur.
We report here on data that is part of a larger study of eight student teacher/cooperating teacher pairs, and the core themes
that emerged from their conversations. We focus on two pairs for whom the core conversational themes represent disparate approaches
to mathematics in and for teaching. One pair, Blake and Mr. B., focused on controlling student behavior and rarely talked
about mathematics for teaching. The other pair, Tara and Mr. T., focused on having students actively participating in the
lesson and on mathematics from the students’ point of view. These contrasting experiences suggest that student teaching can
have a profound effect on prospective teachers’ understanding of mathematics in and for teaching.

ABSTRACTAs a systemic approach to improving educational practice through research, ‘What Works’ has come under repeated challenge from alternative approaches, most recently that of improvement science. While ‘What Works’ remains a dominant paradigm for centralized knowledge-building efforts, there is need to understand why this alternative has gained support, and what it can contribute. I set out how the core elements of experimental and improvement science can be combined into a strategy to raise educational achievement with the support of evidence from randomized experiments. Central to this combined effort is a focus on identifying and testing mechanisms for improving teaching and learning, as applications of principles from the learning sciences. This article builds on current efforts to strengthen approaches to evidence-based practice and policy in a range of international contexts. It provides a foundation for those who aim to avoid another paradigm war and to accelerate international discussions on the design of systemic education research infrastructure and funding. 相似文献

Changed demographics of those now entering the field of school counseling argue for changes in preparatory curriculum, including the curriculum for supervision. The authors present a 5‐component model for supervising graduate students without previous school experience that is based on 2 pertinent studies. This model focuses on information for administrators and site supervisors about research related to nonteachers; immersion in the school context and in other youth‐oriented venues; observation of school culture; structure for site supervision; and awareness regarding development, classroom skills, and lesson planning. Included are sample strategies for addressing the needs of nonteachers through program structure, curriculum, and site supervision. 相似文献
