Socially shared metacognition of dyads of pupils in collaborative mathematical problem-solving processes     

Tuike Iiskala  Marja Vauras Erno Lehtinen  Pekka Salonen 《Learning and Instruction》2011,21(3):379-393

This study investigated how metacognition appears as a socially shared phenomenon within collaborative mathematical word-problem solving processes of dyads of high-achieving pupils. Four dyads solved problems of different difficulty levels. The pupils were 10 years old. The problem-solving activities were videotaped and transcribed in terms of verbal and nonverbal behaviours as well as of turns taken in communication (N = 14 675). Episodes of socially shared metacognition were identified and their function and focus analysed. There were significantly more and longer episodes of socially shared metacognition in difficult as compared to moderately difficult and easy problems. Their function was to facilitate or inhibit activities and their focus was on the situation model of the problem or on mathematical operations. Metacognitive experiences were found to trigger socially shared metacognition.  相似文献   

How do students define their roles and responsibilities in online learning group projects?     

Karen C. Williams  Kari Morgan  Bruce A. Cameron 《Distance Education》2011,32(1):49-62

The goal of this study was to explore the processes of group role formation in online class settings. Qualitative analysis was used to code chat logs and discussion threads in six undergraduate Family and Consumer Sciences online courses that required online group projects. Four themes related to the process of group role formation emerged: testing the waters, apologies as being nice, tag – you’re it, and struggling to find one’s role. Students created roles of leader, wannabe, spoiler, agreeable enabler, coat‐tails, and supportive worker as the group process evolved over the course of the semester. Results lend support for a balance between allowing students to create and experience roles on their own and faculty assignment of roles. Questions are raised related to faculty approaches toward directing and scaffolding the group process.  相似文献   

Enterprise Information Portals in support of business process, design teams and collaborative commerce performance     

Hsin Hsin Chang^{Author Vitae}  I. Chen WangAuthor Vitae 《International Journal of Information Management》2011,31(2):171-182

Enterprise Information Portals (EIPs) have been widely adopted as platforms for the integration of knowledge management and information technology (IT). This study has been conducted from the knowledge management perspective in order to examine the influence of EIPs on collaborative commerce in the automobile industry. This study explores the integration of internal and external business processes and the coordination of collaborative design teams. An initial qualitative investigation explores the practical applications of an EIP in an automobile company. A research model is then formulated and tested using a questionnaire survey of the R&D department of a motor company in Taiwan. The results of the data analysis reveal that presence of EIPs can help a company realize the benefits of c-commerce. EIPs also can improve collaborative commerce performance by promoting the degree of integration of the enterprise process and by strengthening the process innovation and communication of collaborative design teams. The results suggest that managers should reinforce important factors, including knowledge management tools, process integration, and the quality of design teams, in order to achieve success in collaborative commerce.  相似文献   

基于CLUE-S模型和Markov模型的城镇土地利用变化模拟预测——以江苏省常熟市辛庄镇为例   总被引：11，自引：1，他引：10

基于高分辨率遥感影像解译得到江苏省常熟市辛庄镇4期土地利用历史数据,首先对CLUE～S模型的预测精度进行验证,然后利用CLUE—S模型和Markov模型相结合的方法对研究区未来土地利用变化进行3种不同情景的模拟预测,并系统分析了各情景下土地利用变化的时空特征。结果表明,CLUE—S模型在乡镇小尺度的土地利用变化模拟预测效果较好,精度较高。各情景下,建设用地的快速增长仍将在未来的土地利用变化中占据主导地位,且均以消耗大量的水田为代价,河流密布、交通便捷和经济发达的区域将是未来耕地非农化的“热点”区域。生态保护情景和基本农田保护情景对未来土地利用变化的调控效果较好,林地、水体、水田和旱地受到了更好的保护,并在一定程度上抑制了建设用地的肆意蔓延。  相似文献

多期索赔次数奖惩系统拆分等级一种新方法     

李俊海  周亮亮  刘琳琳 《洛阳师范学院学报》2014,(8):101-103

在研究依赖多期索赔次数的奖惩系统时,Centeno and Andrade通过等级拆分方法,使新奖惩系统具有一阶马氏性.然而,现有文献并没有给出规范的拆分等级方法.本文利用高阶马尔科夫链有关知识,给出了一种程序化的拆分等级法,并把它用于葡萄牙的奖惩系统,得到了与Centeno and Andrade相同的结果,验证了新方法的合理性.  相似文献   

The Role of Output in Grammar Learning
