解决分布式需求的内在冲突

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”。     

Network ethnography and the cyberflâneur: evolving policy sociology in education

This paper makes the argument that new global spatialities and new governance structures in education have important implications for how we think about education policy and do education policy analysis. This context necessitates that researchers engage in new methodologies to ensure that there is a suitable link between their research problem and the methods utilised for its investigation. To this end, I suggest that network ethnography can be conceived as a ‘threshold’ methodology; a new way of looking at social relations in changing times with attendant methodological benefits and shortcomings. Here I constitute the network ethnographer as cyberflâneur, who, like the nineteenth-century flâneur is lured by and attentive to the ‘new’, where they embrace the convergence of space and new technologies to become a well-positioned observer of contemporary policy processes. In focusing on the cyberflâneur, this paper aims to provoke debate amongst policy sociology researchers about how we can reflect on and modify our practice to ensure we are contributing to meaningful research in the twenty-first century.     

In Defence of the Modernist Project in Education

This paper advocates the concept of critical modernity, in contradistinction to that of postmodernity, in orientating the practice of education. It draws on work in anthropology, and the writings of Giddens and Habermas, in support of a re-vivified project of modernity. It also presents ideas from on-going communication styles research that may give efficacy in education to Habermas's concept of communicative action.     

Evidence and its consequences in educational research

We begin by arguing that the continuing dominance of ‘evidence-based’ thinking in educational policymaking does serious harm to the notion of evidence itself; also that it brings a loss of coherence to education as a practice that might wish to be regarded as a coherent and research-informed one. The second section of the article suggests that the invidious consequences of ‘evidence-based’ thinking are likely to continue unless energetically challenged by a vibrant and robust understanding of education as a practice in its own right. In elucidating such an understanding, we investigate closely the notions of practice and practitioner, and their intrinsic connections, drawing on landmark researches on practice by authors like Alasdair MacIntyre and Joseph Dunne. Building on the understanding of education as a practice in its own right, the third section argues that the Dewey-inspired notion of justified warrant, rather than proof or replicability, is more appropriate to research claims made in education. Here we focus in particular on action research, which has experienced recurring difficulties in having its research credentials recognised.     

Culture wars in the classroom: Prospective teachers question science

Does studying about the nature(s) of science contribute to a prospective teachers' effectiveness as a science teacher? This research grew out of a course created by a science educator and historian of science who believed prospective teachers needed more complex understandings of the cultural wars surrounding science. The research team consisted of five prospective teachers who participated in the course as well as the two instructors. This paper describes the experience of participating in the course from both perspectives. We argue that studying the cultural wars over science contributes to prospective teachers' professional growth as much because the course elicits tacit beliefs about school science as it introduces more complex understandings of science. We found that prospective teachers' tacit beliefs about school science were their greatest barrier to developing more complex understandings about the nature(s) of science. We contend that willingness to grapple with complexity and developing a professional identity by locating oneself in the conversations about the nature(s) of science are better criteria for determining the professional growth of prospective teachers than knowledge measures. Finally, we argue that prospective teachers should be viewed as professionals who are responsible for finding their own voice, making their own decisions, and considering the consequences of their beliefs on their practice. This study raises questions critical to teacher education programs for prospective teachers and teacher‐educators alike. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 895–915, 2000
