熟练Web用户的搜索行为:关注控制与情感控制的影响   总被引:2,自引:0,他引:2  
本研究调查了作为熟练Web用户的67位本科生的认知特征与情感特征对其Web导航及搜索行为的影响。在研究中,两个标准化测验和一个调查问卷用于收集参与者的认知方式、问题解决方式以及基本资料。通过对调查对象在团体镶嵌图形测验和问题解决问卷两个标准化测试中获得的分数进行因素分析,作者抽取了2个用户因素,即关注控制和情感控制。其中,关注控制因素似乎能影响用户导航行为(如链接和后退键的使用),而情感控制因素不仅影响包括关键词搜索等搜索行为,还影响以查准率和查全率等为指标的检索绩效。  相似文献

Sixty-four 8-year-old boys and girls from urban and rural settings and representing different races and socioeconomic status backgrounds responded to questions about the nature, causes, justification, and alleviation of poverty. Much of what the children said indicated that they had not yet internalized prevailing adult norms and values about the poor in our society. A substantial proportion spoke in ways suggesting forces apart from the individual as causing poverty. Nearly all believed that poverty was not fair. Justifications offered by the children included disavowing economic inequality, or speaking in terms of basic needs or what should or ought to be. A majority mentioned philanthropy or societal change as a way to end poverty. Findings also lend support to the claim of social representations theory that concepts vary as a function of social factors. Future research should employ a design that acknowledges interacting variables to investigate systems of meaning in children's understandings about poverty.  相似文献

This study utilizes public data mining to explore participation divides of all available K-12 institutional Twitter accounts in the U.S. (n?=?8275 accounts, n?=?9,216,853 tweets). Results indicated that U.S. schools used Twitter to broadcast information on a variety of topics in a unidirectional manner and that hashtags included a variety of intended purposes, including affinity spaces, education topics, emotive language, and events. Those schools in wealthier, more populated areas were more likely to use Twitter, with wealthy, suburban schools being the most likely to use it and poor, rural schools being the least likely. Furthermore, factors such as charter school status and urbanity influenced the content of school tweets on key issues, with schools in more populated areas tweeting more about coding and college than schools in less populated areas and charter schools tweeting more about college and the politicized educational issue of common core than non-charters. These results reveal participation differences between schools based upon demographics and provides a basis for conducting future large-scale work on publicly available artifacts, such as school tweets, that may be meaningfully used as education research data.  相似文献

The aim of this study was to examine metacognition in computer-supported collaborative problem solving. The subjects of the study were 13-year-old Finnish secondary school students (N = 16). The Knowledge Forum learning environment was used to support student pairs’ problem-solving task involving polygons in a geometry course. The data consist of the student pairs’ posted computer notes (n = 95). To examine metacognition in a social context in the networked discussions, the features and patterns of networked interaction, the metacognitive content of the computer notes and their relations were examined. To examine the features of networked interaction, the social network analysis measures were used. The patterns of networked interaction were displayed with the multidimensional scaling technique. In the analysis, metacognitive contents of the computer notes were categorized as metacognitive knowledge, metacognitive skills, and not metacognitive. Further, with the correspondence analysis, we examined how the student pairs’ metacognitive activity was distributed. The results of the study revealed that the metacognitive activity varied among participants, although some aspects of metacognition such as planning were never encountered. It was found that there is a relation between metacognitive activity and the features of interaction. The student pairs who monitored and evaluated the ongoing discussions had a strategically optimal position in the communication network.  相似文献

Purpose: The sector-wide approach currently dominates as the strategy for developing the agricultural sector of many African countries. Although recognised that collaborative agricultural research is vital in ensuring success of sector-wide agricultural development strategies; there have been few efforts to understand the dynamics of national agricultural research/development networks in Africa. This study fills this gap by analysing the dynamics of networking and interactions between institutions in the National Agricultural Research System in Malawi. Design/Methodology/Approach: The study sampled actors in the National Agricultural Research System in Malawi, which included the main public agricultural research department, academic institutions, semi-autonomous research institutions, private companies and international agricultural research institutions. Data was analysed using Social Network Analysis. Findings: Results demonstrate that public agricultural research departments play a central coordinating role in facilitating information sharing; with other actors remaining on the periphery. However, it also shows the important role other actors play to relay information to a wider network of stakeholders. These secondary information pathways can play a very crucial role in ensuring successful implementation of the national agricultural research agenda. Practical implication: Policy-makers are called upon to integrate other research actors into the mainstream national agricultural research information network. This is vital as other research actors are, at the global level, increasingly taking up a greater role in financing and disseminating research and research results. Originality/Value: The study contributes greatly towards knowledge needed for continuing the transformation of African agricultural research; and aligning the African agricultural research vision and practice with the emerging global agricultural research paradigm.  相似文献

隐喻是新闻文体的一个重要特征.通过分析汉语和英语的体育新闻语篇,发现新闻语言中使用了大量的隐喻,首先,从宏观上看,概念隐喻普遍存在于竞技性的运动项目的赛事报道之中;其次,从微观上看,体育竞赛中的技术动作描写也采用了隐喻,体现了新闻语言的艺术特色和审美价值.最后,分析了体育新闻语篇中隐喻的三大功能:语篇功能、审美功能和社会功能.  相似文献

半个多世纪以来,民主社会主义由理论到实践,由一国实践到多国实践,已经形成一股历史潮流,取得了一定的成就。然而,它们所建设的福利社会仍然是资本主义而并非社会主义。因此,我们不能把它们作为样板,走它们的改良主义道路。  相似文献

公正是贯穿科举考试中的一条红线。科举考试对官宦庶民一视同仁,从考场专门设置、糊名誊录、双重定等第、别头试和锁厅试等方法的采用,都力图给中小地主阶级和平民百姓通过科举入仕实现向上社会流动提供了一个公平竞争的平台。公平竞争、择优录取是科举制得以长期存在的重要原因,科举制度使封建社会通过选纳社会精英进入政治权力中心而不时迸发出活力。  相似文献
