Summary This article examines the role a university library plays in planning the student support services that are so crucial to a successful distance learning program. The content of the paper is based on the experience the author acquired as a member of Texas Tech University's Distance Learning Council. The Council's efforts to plan, prioritize, and develop a distance learning program that will include strong support from the Library are emphasized. The work of the Distance Learning Council and its committees is discussed when it relates to the TTU Library's contribution to the program. 相似文献

二十多年来,参考咨询与信息服务日益介入电子世界,而逐渐远离图书馆的参考咨询台和纸质馆藏.本文介绍一项基于不断变化的环境针对参考咨询与信息服务进行的研究,旨在分析两个研究问题:①从用户和馆员行为及其所利用信息源的角度来看,当前参考咨询与信息服务活动有哪些趋势?②当前参考咨询过程的基本模型是什么?作者通过焦点访谈法搜集承担参考咨询与信息服务专业课程教师的意见,并通过自由讨论的形式征集其他专业课程教师和博士研究生有关虚拟参考咨询教育的看法.研究结果表明,参考咨询模型具有明显的互动性和合作性,其中参考馆员和用户均扮演信息获取、信息接收和信息生成的角色.论文提出参考咨询过程的模型,并分析这一模型对参考咨询与信息服务活动产生的影响.图1.参考文献63. 相似文献

The ESRC Teaching and Learning Research Programme is expected to produce knowledge of high social scientific quality and practical pedagogic value. It faces, in a particularly acute form, the issue of how confidence in its conclusions can be built. This article begins with some conceptual clarification of the notion of a ‘warrant’ for research findings and distinguishes between warrants in social research and warrants for educational policy and practice. It then, in the specific context of research on learning outcomes, proposes an integrated model that recognizes the importance of, and relationships among, criteria associated with research design and empirical work, theoretical coherence, relationship with other research, and user affirmation. It concludes by emphasizing the need for continuing debate about, and development of, the roles and relationships of ‘researchers’ and ‘users’. 相似文献

国外为企业量身打造的顾客满意度模型不适合于教育网站用户测评,国内教育领域一些学者提出的测评方法局限于各自的研究主题不足以推广。教育服务网站用户满意度模型由网站内容服务、网站功能服务、网站建设质量、用户满意度等子模型构成,该模型可复制性强,变量设置全面,简单方便,成本低廉,能在资源有限的情况下最大限度地促进网站的改善,以提高用户满意度。 相似文献

在中国当前发展背景下,基本公共服务是扶贫开发的重要衡量标准、为挟贫开发营造良好的外部发展环境以及二者的目标存在一致性等联动关系。但当前贫困县贫困现状及挟贫开发方式和效果具有自身局限性.对基本公共服务有重要影响;贫困县应基于自身在促进扶贫开发和基本公共服务过程中的特殊定位,从选择地区扶贫方式、完善其基本公共服务、整合基本公共服务与扶贫开发等方面的确定发展思路。 相似文献

受“搜索引擎”流行的影响,目前大家已经习惯把图书情报领域使用的“情报检索系统”称之为“学术搜索引擎”。无论从技术层面上还是应用层面上,尽管二者有很大的共同点,但也有很大差异。传统的集中式的搜索引擎已经无法满足飞速发展的信息爆炸和普及化的海量需求用户,能够提供“云服务”的分布式搜索引擎已经成为必然。文章主要内容包括学术搜索引擎涉及的关键技术、分布式搜索引擎的架构,以及分布式搜索引擎在大数据领域的主要应用价值三个方面,最后给出了分布式搜索引擎RMSCIoud的典型应用介绍。 相似文献

Web-scale discovery systems are gaining momentum among academic libraries as libraries seek a means to provide their users with a one-stop searching experience. Illinois State University's Milner Library found itself in the unique position of having access to two distinct discovery products, EBSCO Discovery Service and Serials Solutions’ Summon. Two researchers at Milner conducted a usability study for the former product in 2010, and now two other researchers, including one involved with the EBSCO Discovery Service study, have conducted the same study on the latter product. The goals of the study were twofold: first, to identify user behavior while using discovery systems’ search features and to see whether using these features would improve the user's searching experience, and second, to compare user experiences with EBSCO Discovery Service and Summon at Illinois State University. The similarities and differences in user expectations, use, manipulation, and satisfaction with both discovery tools are explored in this article, with the ancillary hope that libraries investigating discovery tools might be able to make a more thoroughly informed choice in acquiring their own Web-scale discovery system. 相似文献

ABSTRACT Digital libraries and collections are a growing facet of today's traditional library. Digital library technologies have become increasingly more sophisticated in the effort to provide more and better access to the collections they contain. The evaluation of the usability of these technologies has not kept pace with technological developments, however, and the end-user has in some cases been left behind. This research study evaluates the usability of digital collections created using the CONTENTdm Digital Collection Management System, a software system used by the University of North Carolina at Chapel Hill. Specifically, this study addresses the following questions: Does CONTENTdm meet users' needs? Is the interface sufficiently intuitive for them to use it? Is the experience of exploring digital collections using CONTENTdm satisfying to users? Employing usability testing techniques with actual-end users, this study attempts to assess the efficacy of the CONTENTdm public interface as well as user attitudes toward it. Ten participants from three user groups—faculty, library science graduate students, and the general public—performed eleven tasks designed to test the key functions of CONTENTdm-created collections and then answered a series of questions about their experiences. Key findings from this study indicate that while the included digital collections are useful and desirable to end-users, the interface generated by CONTENTdm can be confusing even for those who have considerable experience using the Internet. Results from this study may be used to improve this software system and add to the literature surrounding the usability of digital libraries in general. 相似文献
