Analytic Frameworks for Assessing Dialogic Argumentation in Online Learning Environments 总被引:3,自引:2,他引:1
Douglas B. Clark Victor Sampson Armin Weinberger Gijsbert Erkens 《Educational Psychology Review》2007,19(3):343-374
Over the last decade, researchers have developed sophisticated online learning environments to support students engaging in
dialogic argumentation. This review examines five categories of analytic frameworks for measuring participant interactions
within these environments focusing on (1) formal argumentation structure, (2) conceptual quality, (3) nature and function
of contributions within the dialogue, (4) epistemic nature of reasoning, and (5) argumentation sequences and interaction patterns.
Ultimately, the review underscores the diversity of theoretical perspectives represented within this research, the nature
of dialogic interaction within these environments, the importance of clearly specifying theoretical and environmental commitments
throughout the process of developing or adopting an analytic framework, and the role of analytic frameworks in the future
development of online learning environments for argumentation.

面授和网上教学有机结合的整合式教学越来越成为高校教育和培训的主要模式。本文旨在介绍和分析香港理工大学教学发展中心(简称EDC)如何通过网上教学平台的功能,与面授教学结合起来,发挥面授教学和网上教学的各自优势,使教师培训更加有效。EDC的实践表明,在大学教师培训课程中,发挥网上教学的优势,能帮助学员弥补由于有限的面授教学产生的师生之间、学员和学员之间互动的不足。在网上学习中,通过互相的学习观摩和观念碰撞,能激发学员的学习兴趣,有效地促进学员之间进行探究性学习,同时,这种集体学习的方法,能促进在职教师之间的友好交往和学术交流。 相似文献

问题乃是通向理解之门.问题可以激发学习者的求知欲和探究欲,有利于推动教学的开展和促进学习者认知能力的发展.在线学习环境下为促进学习者认知能力的发展提供了丰富的认知工具和资源.但是,由于缺乏对教学问题导向作用的关注,在线课程在促进学习者认知能力发展方面存在着不理想之处,不能有效地引起认知上的深度理解.在文献研究和案例分析的基础上,综合分析了国内外问题导向在在线学习课程中的经验与不足,构建了问题导向促进学习者认知能力发展的在线学习框架和课程实例.在课程设计中提供了以问题为引导的情境体验和探究互动的机会,通过丰富的案例学习和认知支架,让学习者在问题解决过程中学会自主探究和深度思考,引导学习者从对知识的低水平认知层次逐渐向高水平认知层次发展.最后,为了验证问题导向在线课程对学习者认知发展的促进作用,采用实验调查等方法进行了实证研究. 相似文献

为衡量国家重点实验室在新时代背景下的网络媒体影响力,构建网络媒体影响力评价体系,以此分析国家重点实验室的网络媒体影响力水平。利用层次分析法构建国家重点实验室网络媒体影响力评价指标体系,并计算相应的权重系数,同时选取156所国家重点实验室进行实证研究。研究显示,国家重点实验室间的网络媒体影响力参差不齐,且大多数与第三方平台影响力水平同步;国家重点实验室在自主平台特别是微信和官网的利用上还有很大的提升空间。并据此建议积极与多类社交媒体建立联系、强化微信公众号的内容建设以及加强对官方网站的建设与维护等建议。 相似文献

Recent privacy-related incidents of mobile services have shown that app stores and providers face the challenge of mobile users’ information privacy concerns, which can prevent users from installing mobile apps or induce them to uninstall an app. In this paper, we investigate the role of app permission requests and compare the impact on privacy concerns with other antecedents of information privacy concerns, i.e., prior privacy experience, computer anxiety, and perceived control. To test these effects empirically, we conducted an online survey with 775 participants. Results of our structural equation modeling show that prior privacy experience, computer anxiety, and perceived control have significant effects on privacy concerns. However, concerns for app permission requests have approximately twice as much predictive value than the other factors put together to explain mobile users’ overall information privacy concerns. We expect that our findings can provide a theoretical contribution for future mobile privacy research as well as practical implications for app stores and providers. 相似文献

Fast development of IT and ICT facilitate customers to post a large volume of their concerns and expectation online, which are widely accepted to be a valuable resource for product designers. However, it is found that only a small number of small and medium-sized enterprises (SMEs) have capabilities to leverage customer online insights for design innovation, which often demonstrate a significant share in national economies growth. To discover the beneath reasons regarding the barrier that prevent them to make effective utilization, in this study, as a concrete example, manufacturing SMEs in the South Wales and Greater Manchester industrial areas of the UK are focused and their potential motivations for using and knowledge of big data-based customer analytics are investigated. An exploratory survey was conducted in terms of the type of customer data they have, the storage approaches, the volume of customer data, etc. Next, a carefully devised exploratory study was undertaken to understand how SMEs perceive the relations between customer data and product design, how about their expectations from big customer data analytics and what really challenges SMEs to exploit the value of big customer data. Besides, a demonstration platform is developed to present SMEs an automatic process of analysing customer online reviews and the capacity on customer insights acquisition and strategic decision making. Finally, findings from two focus groups indicate the different managerial and technical considerations required for SMEs considering implementing big data and customer analytics. This study encourages SMEs to welcome big customer data and suggests that a cloud-based approach may be the most appropriate way of giving access to big data analytics techniques. 相似文献

Online games are highly popular applications. While online gamers actively participate in gaming teams, no study has yet explored whether gamers have sufficient teamwork knowledge and have accumulated sufficient team participation experience. These likely strengthen team commitment, but we do not know, indicating a research gap. Research filling this gap could shed light on useful means for enhancing gamers’ team commitment. Grounded in social identity theory, we theorize the mechanism that links gamers’ overall gaming team participation experience and overall gaming teamwork knowledge to their team commitment. We collect two-wave data from 344 online gamers that have played massively multiplayer online role-playing games (MMORPGs) and use structural equation modelling for data analysis. We find that overall team participation experience is positively related to gaming team identification, while overall teamwork knowledge is positively related to compliance with gaming team norms. Both team identification and norm compliance are positively related to gaming team commitment. This study is the first to clarify the mechanism underlying the impacts of overall gaming team participation experience and overall gaming teamwork knowledge on gamers’ team commitment. Our findings provide the practical insight that game designers should incorporate game features that require or reward gamers’ participation in gaming teams or enhance gaming teamwork knowledge, thus strengthening gamers’ team commitment. 相似文献

Satisfaction and post-purchase intentions with service recovery of online shopping websites: Perspectives on perceived justice and emotions 总被引:1,自引:0,他引:1
This study explores post-recovery satisfaction and post-purchase intentions with service recovery of online shopping customers from the perspectives on perceived justice and emotions based on twenty scenarios that combine five service failures and four recoveries. Analytical results indicating that in addition to enhancing post-purchase intentions and post-recovery satisfaction among customers, distributive justice increases positive emotions and decreases negative ones. Additionally, procedural justice enhances post-recovery satisfaction as well as increases positive emotions and decreases negative ones, while interactional justice only increases post-recovery satisfaction of customers. Moreover, while positive emotions increase post-recovery satisfaction, and vice versa. Post-recovery satisfaction positively affects post-purchase intentions. Results of this study provide a valuable reference for operators and managers of online shopping websites. 相似文献
