Social networking sites are considered a valuable resource to maintain existing friendships even over considerable distances. The present study emphasizes tie strength as a crucial determinant for the use of interactive and passive features among 302 active Facebook users and friends of different relational closeness (close friends vs. casual friends vs. acquaintances) as well as a moderator for the impact of physical distance. As expected, tie strength affected direct interaction linearly, whereas social surveillance followed a quadratic trend. Furthermore, moderation analyses revealed less frequent direct interaction between close friends and stronger surveillance of casual friends’ profiles as physical distance increases. These results indicate different functions in relationship maintenance for both behaviors as direct interaction aims at nurturing current relationships, while surveillance serves as a catalyst for promising future communications. As a consequence, physical distance influences direct interaction adversely due to emerging constraints but also contains informational value encouraging information-seeking behaviors. 相似文献

Oh and LaRose (2016) contended that problem severity and channel publicness shape support seekers’ goals, time spent composing messages, and the sophistication of those messages. The current study seeks to replicate and extend Oh and LaRose’s study to produce a more accurate understanding of the factors that influence the sophistication of support-seeking messages online. Support seekers’ goals varied according to the severity of a stressor and the publicness of a channel, and the amount of time people spent composing a message influenced its sophistication. We extend the original study by examining associations that were not initially tested. Time spent composing messages mediated the influence of problem severity on the quality of people’s messages, and this effect was moderated by channel publicness. 相似文献

Many librarians struggle with how to balance scalable instructional offerings with more personalized instruction for online students—scale tends to come at the cost of personalization and vice versa. This paper will discuss three methods for connecting with online students that range from one-to-one personalization to widely scalable instruction: individual consultations, scaffolded instructional webinars, and asynchronous video tutorials. The student engagement with each type of instruction will be discussed, with ideas for future directions provided. 相似文献

ABSTRACTThis article answers the question “Are the sourcing practices in Finnish online journalism trustworthy?” Here, trustworthiness is operationalized as the fulfillment of audience expectations towards sourcing practices. To this end, expectations of young Finnish adults (aged 18–28) were compared to the observed practices of Finnish online journalists. A total of 36 news items (from 12 journalists working in three newsrooms, published in 2013 and 2017) were analyzed. The analysis indicates that online journalists’ sourcing practices largely do not conform to this audience segment's expectations. Namely, the audience expects more comprehensive investigation and thorough verification than what is common practice in online journalism. The use of high-credibility sources is both expected and commonplace. The results imply that transparency may be harmful rather than beneficial to journalism's credibility, as the unveiled practices do not always meet audience expectations. 相似文献

Increasingly, online learning is perceived as an effective method of instruction. Much recent educational research has focused on examining the purposes and situations for which online education is best suited. In this paper, students enrolled in two online courses are compared with their peers enrolled in equivalent classroom‐based courses to investigate aspects of the relationship between learning style and mode of delivery. Student satisfaction measures are taken from participants in both modes of delivery and compared with student learning style. Feedback from the ‘Reflector’ learning style demonstrates higher satisfaction levels with the online mode of delivery compared with their matched counterparts following equivalent classroom‐based courses. Therefore, whilst ‘Reflectors’ might be regarded as Introverts in the traditional classroom setting, the additional time for reflection offered by online delivery makes this group more likely to contribute to online discussion, report higher satisfaction levels and generally behave more like online Extraverts. 相似文献

混合式学习能够整合课堂面授学习方式与在线学习方式的优势,被认为是高等教育机构应对未来挑战和实现教育创新的有效而风险较低的策略。以北京大学一门通选课作为研究案例,针对混合式教学环境下学生网上讨论的成效及影响因素进行的实证研究发现:混合式教学中的网上讨论确实可以为教学提供帮助,总体来看,学生在"知识"和"理解"这两个低阶思维能力方面获得了较大的提高,而在"分析"、"综合"、"评价"等高阶思维能力方面并没有得到普遍的提高;"讨论话题设置"和"个体对网上讨论的态度"是影响网上讨论成效的最显著因素,"对讨论的激励机制"对网上讨论成效也有较大影响。 相似文献

网络远程课程,即网络课程与远程课程的合称。自2000年以来,我国网络远程课程研究已走过10年(2000—2009)历程,已有研究在课程内涵、课程设置、课程设计、课程开发、课程建设、课程实施和课程评价等方面都存在不同进展与不足。基于开放本质的整体设计和基于成人特色的学教设计,是课程设计的两大方向;课程开发中课程设计与课程理念、课程设置的研究存在脱节现象;目前课程建设的整体规划、教学设计水平有待提高,优秀资源共享程度较低;课程实施中缺乏实施机制和实效研究,不注重研究成果转化;课程评价则存在评价指标和量化标准上重复研究的情况,评价的目的多为评质定级而不是反馈改进。当前网络远程课程的发展需要具有全程、综合、以“学”为中心的研究视野,树立动态的、学科开放的、学习开放的网络远程课程观,建立专业化的团队,注重试验研究,注重研究成果的及时转化。 相似文献

This study investigated the role of working memory capacity as a factor for individual differences in the ability to compose a text with communicative efficiency based on audience awareness. We analyzed its differential effects on the dynamics of the writing processes, as well as on the content of the finished product. Twenty-five graduate students composed a procedural text explaining how to assemble a model turbine. They were free to consult a documentary source, featuring captioned pictures of turbine parts and assembly steps, at any time. Graphomotor and eye movements were recorded using ‘Eye and Pen’ software with an eye-tracker and digitizing tablet. Results showed that high WM capacity writers used a different strategy to explore the visual source, making longer writing pauses and producing more detailed procedures, and achieved the communicative goal more efficiently, by introducing more reader supports. In conclusion, we discuss the feasibility of audience awareness training. 相似文献
