The Effect of Web Search Result Display on Users’ Perceptual Experience and Information Seeking Performance     

Hosam Al-Samarraie  Ahmed Isam Al-Hatem 《The Reference Librarian》2018,59(1):10-18

ABSTRACT

Adding multiple sources of information in the display of Web search results may negatively affect users’ perceptual experience and information-seeking behavior. This claim was established by investigating the impact of different Web search compositions on users’ ability to extract specific information. In this article, we assumed that the quantity and order of different compositions (areas) in the Web search results page may contribute to individual’s ability to find information relevant to their search queries. An eye-tracking device was used to observe and compare the perceptual behavior of 14 users in an information-seeking task. The results showed that the use of different compositions in the display of Web results page significantly influenced users’ perceptual experience by reducing their attention to the organic results area. The quantity of these compositions was found to greatly increase the cognitive load of users when attempting to retrieve information from the organic area, which negatively affects their information-seeking performance. Our finding provides a rationale for further studies to consider the impact of quantity and order of Web page compositions on individuals’ perceptual attention and cognitive load in information-seeking task settings.  相似文献   

OER evaluation as a means of teaching information literacy in individual and small group settings     

Sarah Evelyn  John Kromer 《The Reference Librarian》2018,59(1):1-9

ABSTRACT

Open education resources represent a great opportunity to reduce textbook costs, but many of them have not been evaluated for quality. Librarians and former students in an introduction to engineering course collected and evaluated open education resources to supplement the course textbook in future semesters. Both searching for and evaluating these resources created opportunities for the librarians to evaluate information literacy skills of these students and to provide instruction to improve these skills.  相似文献   

当前科学教育几种主要价值取向评析   总被引：1，自引：0，他引：1  

LIU Ke-wen 《教育理论与实践》2007,(15)

20世纪中叶以来,科学技术的迅猛发展,引起了人们社会生活各个方面的极大变革。这种变革对中小学科学教育观念产生了极大的影响,进而导致科学教育的价值取向也随之发生了变化,概括起来目前主要有四种科学教育价值取向,即培养"英才"的科学教育价值取向、人本主义科学教育价值取向、STS教育价值取向和培养学生科学素养的价值取向。  相似文献

回顾与前瞻:用社会主义核心价值体系引领社会思潮的有效途径     

石秀杰  董慧  齐凤 《河北师范大学学报(哲学社会科学版)》2011,34(6)

自党的十七大提出积极探索用社会主义核心价值体系引领社会思潮的有效途径以来,学术界对此给予了极大的关注,并围绕着提出的必要性、有效途径和制度保障三个部分进行了广泛的研究,取得了丰硕的成果。但还存在着如:基础研究薄弱、宣传解读性成果较多;不同理论观点缺乏碰撞与争鸣等,这些问题还有待于进一步深化和拓展。  相似文献   

The role of a digital engineering platform in appropriating the creation of new work-related mind-set and organisational discourse in a large multi-national company     

《International Journal of Information Management》2019

This paper reports on a case study involving a strategic and innovative approach to creation of an in-house multifaceted digital engineering platform (the DEP) in overcoming a number of organisational problems at a multinational engineering company. The DEP was to be used strategically for simplifying the operational complexity and to create and appropriate new work-related mind-set and new organisational discourse to achieve homogenous working across the organisation, which is a huge challenge. The need for this system emerged from the need to resolve many organisational services related problems that carried phenomenal amount of processes, health and safety risks and to regulate, and, control the running of engineering project. Research data were collected using a longitudinal case study approach over a period of six months. In order to make sense of how the DEP helped the organisation, the study used certain elements of Extended Structuration Theory as a lens to assess the case study. This research discovered that the DEP succeeded in creating and appropriating work-related mind-set and organisational discourse. It also had real influence on working processes and employees at all levels while encouraging transparency, responsiveness, agility and accountability. It continues to help the organisation to govern, manage and maintain good standard of service but many barriers still remain.  相似文献   

Idea generation in biomedical engineering courses using Design Heuristics     

Jin Woo Lee  Anastasia Ostrowski  Aileen Huang-Saad  Colleen M. Seifert 《European Journal of Engineering Education》2019,44(3):360-378

ABSTRACT

With increasing demand for improved medical equipment and healthcare, next-generation biomedical engineers need strong design skills. Equipping biomedical engineering students with tools for idea generation and development can increase student design success. Design Heuristics are an ideation tool developed through empirical studies of product designs. While identified in the mechanical engineering space, Design Heuristics may be applicable in biomedical engineering design. In our study, we implemented a Design Heuristics session during upper-level undergraduate and first-year graduate biomedical engineering design courses. We examined the applicability of Design Heuristics within individual and team concept generation contexts. The findings demonstrated that biomedical engineering students were able to use Design Heuristics to generate multiple concepts, and that initial concepts produced using Design Heuristics were carried over into final team design. The results support the applicability of Design Heuristics to student idea generation in biomedical engineering design.  相似文献

大型赛事赞助、网络关注度与企业市场价值--2018年俄罗斯世界杯中国赞助商实证研究     

付磊  蔡兴林 《体育科学》2020,(4):28-34

企业赞助大型体育赛事目的是为了提升企业的市场价值,针对多家中国企业赞助2018年俄罗斯世界杯的事件,用事件研究方法考察了企业签约赞助和开赛日2个阶段股票价格的异常收益波动,并用百度指数研究了网络关注度对异常收益的影响关系。研究发现,中国企业赞助俄罗斯世界杯,在签约事件窗口内企业获得正向的市场绩效,而在开赛日事件窗口内企业获得负向的市场绩效。百度指数与股票异常收益的关系,说明网络关注度对事件影响产生催化剂的作用。研究结果表明,企业赞助大型赛事需要注重短期和长期的效果,注意防止过度炒作,并要积极采用营销组合的手段扩大赞助带来的影响和收益。  相似文献
