基于QQ群的高校科研协作平台模式构建

腾讯QQ以其强大的互动性,同步与异步交流兼容,支持群共享,群聊、私聊、邮箱,QQ空间,微博,微信等功能特性,成为当下最为流行网络互动软件之一.本文简述了科研团队协作平台的研究现状,阐释了科研团队QQ群的概念,分析了基于QQ群的科研协作平台的特点,以施拉姆的传播理论为指导,提出了科研团队协作平台的应用模型,以期促进科研团队成员的信息交流、学术共享、科研协作和知识管理,有助于科研团队的可持续发展和成果产出.     

Collaborative research for sustainable learning: the case of developing innovation capabilities at Volvo Cars

This paper aims to make a contribution to the stream of literature on action research by describing a longitudinal collaborative research project which evolved out of a long-term, participation partnership with Volvo Cars. The collaboration was aimed at developing innovation capabilities in the company and accumulating knowledge on how capabilities are developed. The paper provides insights into the design of collaborative research projects to enable mutual, sustainable learning. It draws on key notions in the literature on collaborative management research and action learning, highlighting the research design of the project at Volvo Cars and its relations to action learning. The paper describes how the research design opened the way to establishing a learning system at Volvo Cars while simultaneously generating new scientific knowledge within the area of innovation capabilities. The paper provides rich and detailed data on a collaborative research setting and highlights key aspects related to organizing and undertaking collaborative research.     

大型网络学术资源导航联合建设项目RDN的案例分析

联合建设模式目前已经成为大型网络学术资源导航项目的主要建设形式。本文对具有代表性意义的RDN的联合建设模式进行了分析，包括其合作模式、合作级别、标准规范和服务政策，并在此基础上，总结出对国内联合建设大型网络学术资源导航的几点借鉴意义。     

高等师范院校资料室建设之我见

高校系资料室是高校图书馆的重要组成部分，是为教学、科研提供资料的基地，是本系的专业文献资料信息中心，是教师和学生进行及时“充电”的平台。在信息化的今天，我们如何建设各院系资料室成为当务之急．本文将从院系资料室的藏书建设、深层性服务、与图书馆共建三方面谈高等师范院校资料室的建设。     

共同思考和共同学习：课堂讨论的干预研究

在日本的课堂中,学生受到两种不同力量的影响,一种为竞争,即学生都迫切希望成绩更优异;另一种为基于集体的共识,即同样这些学生必须相互合作以应对日常生活。这两种相互矛盾的力量对学生的行为和讨论产生了影响。通过开展一项名为＂通过合作学习＂的教育干预研究,对干预的效果采用了定性和定量的分析,用智力测验测量了学生集体完成非言语推理任务的能力,对干预的前-后测结果进行分析,发现干预是有效的。我们发现,小组讨论质量和个体推理能力有所提高,一些在小组活动和小组讨论中有困难（孤僻、不参与活动或被忽视）的学生有了进步,教师对小组讨论的看法以及管理小组讨论的技能也发生了改变。同时,我们也发现了某些障碍使得小组活动无法很好地进入课堂。可能需要提供进一步的干预才能实现＂班级＂的合作功能。     

The Brink of Change: Gender in Technology-Rich Collaborative Learning Environments

This study was designed to contribute to a small but growing body of knowledge on the influence of gender in technology-rich collaborative learning environments. The study examined middle school students attitudes towards using computers and working in groups during scientific inquiry. Students attitudes towards technology and group work were analyzed using questionnaires. To add depth to the findings from the survey research, the role of gender was also investigated through the analysis of student conversations in the context of two activities: exploring science information on a hypertext text and conducting hands-on investigations. The data suggest that not only are girls and boys are similar with regard to attitudes about computers and group work, but that during collaborative learning activities, girls may actually participate more actively and persistently regardless of the nature of the task.     

Reconstruction of a Collaborative Mathematical Learning Process

The study focused on the interaction between two secondary school students while they were working on computerized mathematical investigation tasks related to probability theory. The aim was to establish how such interaction helped the students to learn from one another, and how it may have hindered their learning process. The assumption was that interaction is beneficial for students if they can perform certain key activities, namely showing, explaining, justifying, and reconstructing their work. Both students attained mathematical level raising. However, the student who explained frequently and criticized himself attained more mathematical level raising than the student who did not explain her work frequently or criticize herself.     

适应用户兴趣变化的协同过滤增量更新机制

高维、稀疏的用户-项目评分矩阵对基于项目的协同过滤推荐算法造成严峻的可扩展性问题.传统的解决方法是离线计算项目相似性并保存在系统中以供算法调用,但是不能充分利用最新评分数据以体现用户兴趣的变化.针对上述问题,提出了适合在线应用的协同过滤项目相似性增量更新机制,使得推荐系统在当前用户提交项目评分之后,能够实时完成相应项目与其他项目之间的相似性数据更新,从而推荐系统可以基于最新的项目相似性数据进行推荐处理,以适应用户兴趣的变化.实验结果表明,本文提出的项目相似性增量更新机制能够有效提高基于项目的协同过滤算法可扩展性.     

Use and evaluation of a technology-rich experimental collaborative classroom

In order to pilot a shift towards greater use of collaborative learning in our higher education programs, the University of Hong Kong has invested in the development of a prototype technology-enhanced collaborative learning space. The space was created by retrofitting a vacant studio, turning it into an innovative classroom space in which collaborative learning is promoted and facilitated both through the provision of technology and by the physical layout of the room. We have used the space to pioneer collaborative learning both by holding professional development workshops for faculty in the room and also by helping academic staff to run experimental courses in the learning space. The opportunity to offer professional development and support for academic staff in this environment is particularly valuable as it ensures they do not simply deliver traditional didactic lectures in a space designed to promote interactive student learning and engagement. By using the space as a ‘student’ they are able to consider how they may use collaborative learning environments with their students. This paper describes use of the room for professional development of academic staff and also provides two examples of the use and evaluation of the room by faculty who used the room to teach experimental classes.
