为了提高虚拟实践社区知识转移的质量,促进社区内的知识共享和创新,提出了一种基于语义级的虚拟实践社区知识转移模型构建方法。从虚拟实践社区区别于实践社区和虚拟社区的特殊性出发,运用混合本体方法构建了虚拟实践社区的知识集成框架;构建不同类型的知识转移消息的形式化模型,进而从内容感知的角度,结合相似度计算给出知识转移参与者的选择算法。基于本体构建的社区知识存储模型有利于用户间从语义层次上进行交互,提高社区内知识转移的效率和准确率。 相似文献

文章运用文献资料,问卷调查、数理分析等方法,对乒乓球运动在太原市社区发展现状进行调查.研究结果表明,乒乓球运动太原市社区中群众基础好,但参与人群表现出一定的性别、年龄和职业特征;参与乒乓球运动的社区居民时间投入比较合理,但资金投入水平总体较低,随着收入的提高,居民的资金投入结构呈平衡发展态势;虽然社区居民在参与形式和参与动机上呈多元化发展,但设施、时间和专业指导人员的缺乏依然是制约居民积极参与乒乓球运动的主要因素.本文建议:科学建立社区乒乓球服务管理网络,发挥积极分子骨干和管理作用,整合优势资源,打造基层赛事,实现自下而上的自我服务、自我管理、健康发展的社区体育新模式. 相似文献

不同强度旅游干扰对鹞落坪保护区玉玲花群落物种多样性的影响 总被引:1,自引:0,他引:1
用物种丰富度指数S、Simpson指数D、Shannon-Wiener指数H比较分析了不同强度旅游干扰下鹞落坪保护区玉玲花(Styraxobassius)群落不同层次的物种多样性物的变化。结果表明:乔木层中,低度干扰下多样性指数较大;其他层次中,中度干扰下多样性指数最高。群落分析表明,低度干扰下几种多样性指数分别为39、3.0946、0.9538;中度干扰下,多样性指数最高,分别为40、3.5981、0.9568;高度干扰下,分别为31、3.0053、0.9457,多样性指数最低。 相似文献

Teaching has been described as an emerging community of practice. Within such professional communities, the processes of reflection and collaborative dialogue, or critical transformative dialogue, are central to the maintenance and improvement of professional practice for individuals, and the field. This paper reports on the challenges experienced by a group of first-year pre-service teachers engaging in a process of reflection and critique with peers, as they participated in a program focused on the development of core practices of teaching. These pre-service teachers' responses indicated their growing understanding of the importance of engaging in ongoing critical dialogue, as part of the “unnatural” aspects of teaching. The paper concludes with a reflection on the value of feedback from the earliest stages of professional learning. 相似文献

This article describes the ways in which critical events in the lives of college students may contribute to their career development and personal well being. These critical events are referred to as 'butterflies', adopting as a metaphor that concept from chaos theory which states that relatively small events can have large effects. The study analyzes these events and their effects from the perspective of the students' mentors. Results of the study are related to other concepts from chaos theory including bifurcation points, autopoiesis and emergence. The study explores both the different kinds of critical events students experience as well as how mentoring may help students to deal with them. The role of the mentor as interpreter of events, as change agent and as intervener are identified. The article argues that mentors need to be aware of the potential power of critical events in the career development of college students. 相似文献

Researchers have shown the benefits of mentoring in both personal and professional growth. It would seem that group mentoring would only enhance those benefits. This work represents a literature review of peer-reviewed articles and dissertations that contribute to the theory and research of group mentoring. This work reviews the articles that contributed to the development of group mentoring theory as well as relevant research. Four primary types of group mentoring emerge—peer group, one-to-many, many-to-one, and many-to-many. Despite over 20 years of research, significant gaps remain in the research methods, demographic focus, and fields of study. The review concludes with recommendations for future research. 相似文献

Mentoring as a strategy to assist and retain beginning teachers in the profession has been perceived as the panacea for reducing attrition rates. Whilst this may be true in many cases, mentoring alone has been unable to stem the flow of resignations. In this essay on scholarship and teaching, the author explores surrounding mentoring programs. New ways of professional learning are suggested that encompass mentoring within a whole school approach, with a particular focus on the school as a collaborative community of learners. 相似文献

Leadership for learning (LfL) is conceived as a network rather than as a centre within the University of Cambridge Faculty of Education. This paper explores what is understood by the term network, both within LfL and in the wider educational and research communities, and how these understandings are reflected in a number of projects carried out under the aegis of LfL over the last three years. The paper draws out the key distinguishing features of these activities and, using the five principles of leadership for learning, explores the degree to which these activities have contributed to the creation and transfer of new knowledge. The paper concludes by proposing a model for knowledge-building which draws on the work of LfL and suggests ways in which this model may be of use to the wider educational community. 相似文献
