Linkages between cognitive and social dialogue patterns during collaborative small-group discussions

BackgroundCollaborative small-group discussions have the potential to promote reading comprehension, critical thinking, and argumentation. However, few studies have gone beyond cognitive processes to understand the social characteristics of dialogue and their potential contributions to students’ cognitive processing in turn-by-turn dialogic exchanges.AimsThis study closely examined dialogues between speakers and addressees regarding their levels of cognitive processing (i.e., cognitive dialogue patterns) and social processes reflecting social cohesion (i.e., social dialogue patterns). The aims were to understand, first, the relations between students' cognitive dialogue patterns and their social dialogue patterns, and second, the relations between students' cognitive dialogue patterns and peers’ social dialogue patterns.SampleThis study included 4070 speaking turns generated by 120 fifth-graders in 60 small-group discussions.MethodsStudents participated in small-group discussions, called Collaborative Social Reasoning. Dialogue between pairs of group members formed social networks, based on which Exponential Random Graph Models (ERGMs) were specified.ResultsFindings showed that speakers' social dialogue patterns were associated with their cognitive dialogue patterns. However, receiving social dialogue patterns from peers did not always predict students’ advanced types of cognitive dialogue patterns.ConclusionsThis study demonstrated that cognitive and social aspects of small-group discussions are intricately linked, and that encouraging social cohesion does not guarantee that students will engage in collaborative and critical discussions.     

政府电子文件协同管理:美国经验及其启示

加强政府电子文件协同管理是促进政府电子文件高效管理和价值实现的有效路径。采用协同创新管理理论框架对近五年美国国家档案与文件署发布的电子文件管理相关政策进行文本分析,并对五个部门工作人员进行访谈,深入了解政策现状,归纳总结出美国在政府电子文高效协同管理方面的措施,揭示其在目标协同、主体协同、客体协同、过程协同、要素协同五个方面的协同经验。最后,结合我国实践需求,提出了借鉴五个方面经验,促进政府电子文件协同管理路径高效的启示。

A collaborative network for first responders: Lessons from the CapWIN case

It is increasingly important for government agencies to collaborate across jurisdictional and functional boundaries. Interorganizational systems supporting interagency collaboration must accommodate a wide range of factors from the external environment and participating organizations as part of their design and operation. This paper presents the findings from a case study of CapWIN, a collaborative network created to enable first responders to share information across jurisdictional and functional boundaries as they work together during emergencies and other critical events. The study examines how aspects of the external environment and the agency context impeded or facilitated the CapWIN collaborative network and the interorganizational system (IOS) that supports it. We identify factors affecting information sharing and collaborative processes, and describe how these factors interact to enable and constrain an IOS. The paper concludes with suggestions for further research on the interplay of environmental, organizational, and technical aspects of interagency collaboration networks as they evolve over time.
