提升英语学习成效的课堂自主学习策略探析   总被引：1，自引：0，他引：1  

张荣干 《课程.教材.教法》2010,(6)

自主学习策略是提升英语学习成效的有效策略之一。自主学习是学习者对自己学习的自觉负责,它具有同是教育之目标与手段的重要性。单元任务可以为自主学习策略教学提供与常规教学相结合的训练,同时,单元任务还可以为自主学习策略教学提供所需要的实践空间与时间。概言之,单元任务为在我国中小学英语教学中培养学生自主学习能力提供了可能的策略教学形式。  相似文献   

A Web of Learning Opportunities     

BRITT ANDERSEN  GUNNAR REE  INGUNN SANDAKER 《European Journal of Education》2010,45(3):481-493

For at least two decades, politicians, academics and other stakeholders have advocated cooperation across sectors, administrative layers and other institutionalised boundaries to achieve objectives of what are called ‘learning regions’ and the ‘lifelong learning perspective’. Boundaries between geographical, institutional and sectors are becoming more porous. Regions and cities may be seen as complex adaptive systems (CAS), and hence do not necessarily follow the logic of formal institutions. While formal institutions have innate interests in regulating interaction and communication between their members, networks develop according to evolutionary or selectionist dynamics, in that the processes of change can be seen as analogous to natural (Darwinian) selection. Networks may be seen as the architecture of complex systems. Research on networks has been relatively extensive in the last 20 to 30 years in mathematics, sociology, anthropology, and biology. There is an emerging science of networks that studies the structure and function of systems. There is also substantial research on the features in the interconnectedness or interdependencies within the system that contribute to explaining the functionality of that system. In this perspective, we may view a learning region as a web of learning opportunities.  相似文献   

解读对等网环境下的知识检索   总被引：1，自引：1，他引：1  

窦永香 《现代图书情报技术》2007,2(6):42-46

知识检索是对等网中分布式节点间实现知识共享的关键。根据对知识检索的理解和对客体对象的挖掘深度不同，将对等网的知识检索环境分解为网络拓扑、节点知识和节点用户3个层次，据此分析总结对等网环境下的知识检索现状，并作进一步展望。  相似文献   

一种基于本体的开放知识导航构建模型与实现     

冯兰萍  张继国 《现代图书情报技术》2007,2(9):54-57

提出一种基于本体的开放知识导航构建模型（Onto_OKN）以解决当前知识导航在构建过程中存在的问题，并分析实现该模型的关键：组件导航新建组件、知识评价组件、导航管理组件。该模型为兴趣用户协作构建知识导航和跨学科知识表示提供了途径，在一定程度上减轻了知识工作者及少数权威领域专家的负担，改善用户对知识共同理解的程度，提高导航的协作能力、知识共享能力，能够向用户提供较高效的知识服务。  相似文献   

Applying participatory design and collaboration in digital public services for discovering and re-designing e-Government services     

Leo G. Anthopoulos  Panagiotis Siozos  Ioannis A. Tsoukalas 《Government Information Quarterly》2007

E-Government projects are currently service oriented, focusing on the implementation and diffusion of digital public services through one-stop points of access for citizens. E-Government strategic plans are political, directed at cost and time minimization during the execution of public services, and they do not take into account citizen needs or public administration operating procedures. Although these plans have led to the development of projects that have succeeded in cost and time savings for both citizens and public administration, surveys conducted around the world show that users evaluate digital public services and do not hesitate to return to traditional methods rather than using digital channels to transact with the public administration again; neither would they recommend the use of digital services to others. This article presents collaborative and participatory tools and methods designed to exploit the knowledge and experience of public servants in the improvement and execution of custom and non-automated public services. Collaborative tools can succeed in the development of real one-stop shops for e-Government, while on the other hand they can encourage both citizens and civil servants to participate in the e-Government era.  相似文献

试论文献知识力     

于鸣镝 《重庆图情研究》2005,6(3):1-4

文章指出，文献不但是一种“双重属性混合体”，而且是一种无限可变的知识力，因此，图书馆人的一个重要使命就是把文献力通过读者转化为“知识生产力”。参考文献4。  相似文献   

对图书馆工作实行结构性改革——知识组织贯穿图书馆工作全过程的设想   总被引：13，自引：0，他引：13  

黄俊贵 《中国图书馆学报》2005,31(5)

当前图书馆工作整体结构与知识组织相左。知识组织应通过读者服务拉动图书馆工作的全面改革,图书馆可设综合科学与公共信息服务部、社会科学文献服务部、自然科学文献服务部、古籍服务部和采集部。如此机构设置具有诸多优点。实施以知识组织贯穿图书馆工作的全过程,关键在于解决认识问题。参考文献5。  相似文献   

用于中文信息自动分类的《中图法》知识库的构建   总被引：4，自引：0，他引：4  

侯汉清  薛春香 《中国图书馆学报》2005,31(5)

中文文献数据库中存在着大量的分类号与关键词(或主题词)对应的人工标引记录。通过对这些数据的加工整理,以《中图法》类目体系为主干,组织各学科领域的语词,从而构建出反映分类号与语词概念对应关系的《中图法》知识库,用以实现信息的自动标引和自动分类。构建《中图法》知识库面临着一些难题:异构数据的整合;原始数据中分类号与主题词或词串之间一对多、多对多关系的筛选;标引词串与知识库中的词串的相符性比较等。图2。参考文献8。  相似文献
