网络资源库的可用性指标设定及其评价方法 总被引：3，自引：0，他引：3
随着互联网的飞速发展,近年来网络资源库大量涌现。而当前无论是电子教学平台的教学资源库,还是电子政务系统的档案历史资源库,抑或电子商务网站的商品资源库,都普遍存在着可用性不高的问题。大部分资源库建设者仍把眼光停留在“收集更多资源”上,将数据容量大作为卖点,导致资源库与用户实际需求存在一定差距,造成资源的可用性不强。面对此问题,首先要解决的是网络资源库可用性评估这一关键环节。本文将从设定可用性指标入手,设计出一套主客观并行测量的网络资源库可用性评价方法。 相似文献

网络课程可用性个案研究 总被引：3，自引：0，他引：3
在网络课程的设计与开发过程中,人们往往优先考虑其教学性(主要体现在教学目标、教学内容、教学活动和教学评价等方面)和技术性(主要体现在资源媒体开发、功能开发和技术标准等方面),而对其可用性(主要表现在易学、易用、高效、低错误率和高满意度等方面)关注不足,即对学习者的学习体验关注不足.本文主要围绕网络课程的可用性以及影响网络课程可用性的要素这一主题,对华东师范大学国家网络精品课程<心理学导论>的可用性情况展开个案研究.本案例研究的首要目的在于测试该门课程原型的设计是否合理,是否受学习者欢迎,学习者的体验是否良构;其次,把该案例作为网络课程可用性测试的典型案例之一,为提炼出影响网络课程可用性设计的要素提供一手参考资料,总结出高可用性的网络课程之间共有的可用性质量要素. 相似文献

This paper proposes a new methodology for checking conformance of the software architectural design of Learning Management System (LMS) to Learning Technology System Architecture (LTSA). In our approach, the architectural designing of LMS follows the formal modeling style of Acme. An ontology is built to represent the LTSA rules and the software architecture in Acme style. Conformity of the design with LTSA rules is tested by reasoning the ontology with the query language SPARQL. A Java-based plug-in system is introduced to implement functionalities like loading the elements of the architectural design into the ontology, mapping the architectural elements with LTSA elements, and performing the conformance test. The advantage of the proposed methodology is two-folded. First, it verifies an important software quality attribute – conformance to technical standard – at an early stage of development, like high-level design phase. Secondly, instead of the conventional manual checklist based approach of conformance testing, this methodology focuses on an automated way to finding the conformance level of the system under check. 相似文献

Recently, because of the rapid increase in the popularity of the Internet, the delivery of learning programmes has gradually shifted from local desktop to online‐based applications. As more and more technological tools become available for online education, there is an increasing interest among educators and other professionals in the application of these tools with regard to online courses. In large‐scale operations, online learning management systems (LMSs) can save cost and time. LMSs are software applications that comprise a suite of tools for learning and teaching online. In conventional educational settings, online LMSs can help to improve the speed and effectiveness of the educational process, communication among learners, and also between staff and students. There are a large number of open‐source and commercially available LMSs on the marketplace, and one of the problems facing an administrator or instructor is how to choose the LMS that can meet his/her needs. This paper describes a software system developed by the author to aid in the selection of a suitable LMS. The software is a web‐based decision support system, titled Easy Way to Evaluate LMSs, and is based on using a multi‐attribute decision‐making algorithm for the effective selection of an LMS. 相似文献

Online educational technologies and e‐learning tools are providing new opportunities for students to learn worldwide, and they continue to play an important role in anatomical sciences education. Yet, as we shift to teaching online, particularly within the anatomical sciences, it has become apparent that e‐learning tool success is based on more than just user satisfaction and preliminary learning outcomes—rather it is a multidimensional construct that should be addressed from an integrated perspective. The efficiency, effectiveness and satisfaction with which a user can navigate an e‐learning tool is known as usability, and represents a construct which we propose can be used to quantitatively evaluate e‐learning tool success. To assess the usability of an e‐learning tool, usability testing should be employed during the design and development phases (i.e., prior to its release to users) as well as during its delivery (i.e., following its release to users). However, both the commercial educational software industry and individual academic developers in the anatomical sciences have overlooked the added value of additional usability testing. Reducing learner frustration and anxiety during e‐learning tool use is essential in ensuring e‐learning tool success, and will require a commitment on the part of the developers to engage in usability testing during all stages of an e‐learning tool's life cycle.

The usability of computer interfaces may have a major influence on learning. Design approaches that optimize usability are commonplace in the software development industry but are seldom used in the development of e‐learning resources, especially in medical education. We conducted a usability evaluation of a multimedia resource for teaching electrolyte and acid‐base disorders by studying the interaction of 15 medical doctors with the application. Most of the usability problems occurred in an interactive treatment simulation, which was completed successfully by only 20% of participants. A total of 27 distinct usability problems were detected, with 15 categorized as serious. No differences were observed with respect to usability problems detected by junior doctors as compared with more experienced colleagues. Problems were related to user information and feedback, the visual layout, match with the real world, error prevention and management, and consistency and standards. The resource was therefore unusable for many participants; this is in contrast to good scores previously reported for subjective user satisfaction. The findings suggest that the development of e‐learning materials should follow an iterative design‐and‐test process that includes routine usability evaluation. User testing should include the study of objective measures and not rely only on self‐reported measures of satisfaction. 相似文献

This paper reports the results of a three-stage usability test of a modeling tool designed to support learners’ deep understanding of the impacts of climate change on ecosystems. The design process involved repurposing an existing modeling technology used by professional scientists into a learning tool specifically designed for middle school students. To evaluate usability, we analyzed students’ task performance and task completion time as they worked on an activity with the repurposed modeling technology. In stage 1, we conducted remote testing of an early modeling prototype with urban middle school students (n = 84). In stages 2 and 3, we used screencasting software to record students’ mouse and keyboard movements during collaborative think-alouds (n = 22) and conducted a qualitative analysis of their peer discussions. Taken together, the study findings revealed two kinds of usability issues that interfered with students’ productive use of the tool: issues related to the use of data and information, and issues related to the use of the modeling technology. The study findings resulted in design improvements that led to stronger usability outcomes and higher task performance among students. In this paper, we describe our methods for usability testing, our research findings, and our design solutions for supporting students’ use of the modeling technology and use of data. The paper concludes with implications for the design and study of modeling technologies for science learning. 相似文献

The rapid uptake of campus-wide Learning Management Systems (LMS) is changing the character of the on-campus learning experience. The trend towards LMS as an adjunct to traditional learning modes has been the subject of little research beyond technical analyses of alternative software systems. Drawing on Australian experience, this paper presents a broad, critical examination of the potential impact of these online systems on teaching and learning in universities. It discusses in particular the possible effects of LMS on teaching practices, on student engagement, on the nature of academic work and on the control over academic knowledge. 相似文献

Current interactive learning environments cannot be accessed by learners with disabilities, in particular for students with
vision disabilities. Modeling techniques are necessary to map real-world experiences to virtual worlds by using 3D auditory
representations of objects for blind people. In this paper, a model to design multimedia software for blind learners is presented.
The model was validated with existing educational software for these users. We describe the modeling of the real world including
cognitive usability testing tasks by considering not only the representation of the real world but also modeling the learner’s
knowledge of the virtual world. The software architecture is also described by using this model, displaying the components
needed to impact learning. Finally, we analyze critical issues in designing software for learners with visual disabilities
and propose some recommendations and guidelines. 相似文献
