教育资源库使用效益评估研究   总被引：1，自引：0，他引：1  

肖君  李雪  陈笑怡  曹俊 《开放教育研究》2012,18(3):105-112

教育资源库是教育信息化的重要组成部分。20世纪90年代以来,国内外掀起了大型教育资源库的建设浪潮。然而,针对教育资源库的使用效益及其评估模式的研究却很少。在目前国家大力推进教育资源库建设及应用的背景下,本文探索并研究了教育资源库使用效益评估的内涵和主要内容,通过充分调研和分析国内外文献,综述了可借鉴的评估项目,包括图书馆使用效益评估、电子政务评估、IT绩效评估、教育信息化评估等内容,在定性和定量分析的基础上分析各评估项目的评估特点,以及我们可以从中借鉴的地方,并且利用聚类分析的方法分析教育资源库使用效益评估需要测量的四个维度。希望本研究能为教育资源库使用效益评估的深入研究奠定基础。  相似文献

Organizing Interpretive Text for a Digital Library: How User Testing Found the Lost Frontier     

《Slavic & East European Information Resources》2013,14(2-3):117-133

SUMMARY

This paper looks at exercises done with user focus groups and how they have influenced the reorganization of Meeting of Frontiers' interpretive text content. Meeting of Frontiers is an international collaborative digital library project at the Library of Congress. Testing consisted of a user survey and card sorting exercises in order to refine the site hierarchy and identify problems with design proposals.  相似文献   

Use of inoculation to foster resistance to credit card marketing targeting college students     

Joshua Compton  Michael Pfau 《Journal of Applied Communication Research》2013,41(4):343-364

Student credit card debt is a growing problem. This study explores the effectiveness of the inoculation strategy to foster resistance to credit card marketing targeting college students. In order to explore further the medical analogy on which the inoculation strategy is based, this study was the first systematically to alter the argument strength of both the counterarguments and refutations in the inoculation pretreatment message to determine whether argument strengths impact effectiveness of inoculation treatments. In addition, this investigation explored whether inoculation spreads from person to person via social channels, similar to the marketing concept of viral marketing. Results indicated that conventional inoculation treatment messages successfully inoculated college students against credit card advertisements, manifested in attitude valence and behavioral intentions, and that matching argument strength is the most effective inoculation strategy.  相似文献   

Card-Sorting Usability Tests of the WMU Libraries’ Web Site     

《Journal of Web Librarianship》2013,7(2-3):205-218

ABSTRACT

This article describes the card-sorting techniques used by several academic libraries, reports and discusses the results of card-sorting usability tests of the Western Michigan University Libraries’ Web site, and reveals how the WMU libraries incorporated the findings into a new Web site redesign, setting the design direction early on. The article briefly describes open and closed card-sorting techniques and quantitative and qualitative methods of analyzing data commonly used in computer and library science fields. Findings from this study allowed the library design team to vastly improve its initial redesign decisions for a new Web site tabbed navigation system. Card sorting not only helped the design team validate its redesign decisions, but it also opened the WMU libraries to outside innovation, inviting Web site visitors to redesign the Web site free from the libraries’ influence. The simple and inexpensive techniques used here may be useful to any Web librarian or design team embarking upon redesign and usability testing of their own sites and interested in building a more compelling, insightful Web site.  相似文献   

Toward a Usable Academic Library Web Site: A Case Study of Tried and Tested Usability Practices     

《Journal of Web Librarianship》2013,7(2-3):99-120

Usability testing is an important element when designing useful, usable academic library Web sites. Since 2001, members of the Florida International University Libraries Web team have worked toward establishing a process that identifies user needs through usability testing. Starting with the libraries’ first Web site redesign project in 2001, the team has taken an active part in improving Web site user experience. After engaging in multiple redesign efforts, the Web team has developed a process that supports awareness of user experience through continual usability testing and feedback gathering. This article presents strategies and practices to measure Web site user experience, including classic usability testing methods (e.g., card sorting activities, focus groups, and task-based user testing), as well as the team's latest effort to assess Web site analytics and content to identify Web site usage patterns and areas of concern. A history of the Florida International University Libraries’ Web site redesign process is presented to illustrate lessons learned and best practices to facilitate future redesign and testing efforts. Taking a longitudinal look at usability testing at one institution, the study aims to inform the development of an effective strategy for user research and content management.  相似文献
