CSCL中基于对话的协作意义建构研究 总被引：2，自引：1，他引：1
协作意义建构是CSCL研究的核心问题之一。从对话的视角,探讨了协作意义建构过程研究的理论基础与研究框架,以具体的网络协作学习课程为案例,运用话语分析的方法,研究了协作学习过程中的对话类型、结构和功能,并深入分析了小组协作学习的过程。研究表明,协作意义建构的过程是一个对话的、社会性的实践过程,小组成员通过不同类型的对话来协商意义、建构知识、创作作品,促进学习者个体对小组共享的理解和意义的内化。认为基于对话的协作意义建构过程的循环模型,对CSCL环境设计、过程分析和评价均具有重要的指导意义。 相似文献

学习科学进行时: 从个体认知到小组认知——美国德雷塞尔大学Gerry Stahl 教授访谈 总被引：1，自引：0，他引：1
计算机支持的协作学习(CSCL)是教育技术研究的重要领域,也是学习科学的一个重要分支。它主要关注的是在计算机的支持下人们是如何在一起进行学习的。计算机和网络技术在协作学习中的应用促进了CSCL的快速发展,目前CSCL已经发展成为一个跨学科的研究领域。不同领域背景的专家从心理学、教育学、人类学、社会学、传播学、教育技术学和学习科学等视角来研究CSCL。CSCL中主要关注的问题是协作学习的本质和计算机是如何支持与促进协作学习的。和个体学习相比,协作学习更具有社会属性,其主要目标是协商意义和建构知识。信息技术介入到协作学习中,改变了学习的方式和形态,同时也产生了许多新的问题。在计算机支持的小组学习环境中,小组学习的过程究竟发展了哪些情况,学习者之间是如何利用技术工具来共同协商意义和建构知识的,信息技术和协作学习之间的相互关系如何,以及研究小组协作学习的理论基础和主要方法都是CSCL领域所关注的问题。美国Drexel大学信息科学学院的Gerry Stahl教授是致力于CSCL研究的知名专家,他是《国际计算机支持的协作学习期刊(International Journal of Computer-Supported Co... 相似文献

为了有效发现当前在CSCL(Computer Supported Collaborative Learning,即计算机支持的协作学习)研究中存在在线学习效果不理想的问题,本研究主要采用调查法分析了CSCL中学习动机对学习活动和知识获取的影响。假设在个人学习和协作学习阶段的学习动机都以一种积极的方式影响着学习活动和知识获取。研究结果显示,CSCL中个人学习和协作学习阶段学习者的目标取向是与学习者学习活动中的知识获取相关联的,学习动机结构类型与知识获取和学习活动存在部分联系。 相似文献

Computer-supported collaborative learning (CSCL) is an approach to learning in which learners can actively and collaboratively
construct knowledge by means of interaction and joint problem solving. Regulation of learning is especially important in the
domain of CSCL. Next to the regulation of task performance, the interaction between learners who work in a CSCL environment
needs to be regulated as well. Despite its importance, the regulation of learning in CSCL has received relatively little attention
in research. In the contributions of this special issue different labels are used for various forms of regulation of learning
during CSCL. During collaborative learning, the regulation of activities can take place at different levels of social interaction:
the individual level, the dyadic level, and the group level. Regulative activities of all three levels are presented in the
three studies. All studies have investigated whether the use of regulative activities affected performance, and have found
that regulation at the dyadic and/or group level was positively related to group performance. In sum, these three contributions
provide a constructive overview of the role of regulation of the (collaborative) learning process in CSCL, both in terms of
the impact of regulation on learning processes and learning results as well as the influence of different kinds of support
on the regulation of collaborative learning. 相似文献

Business needs in many corporations call for learning outcomes that involve problem solutions, and creating and sharing new
knowledge within worksplace situation that may involve collaboration among members of a team. We argue that work-based activities
(WBA) and computer-supported collaborative learning (CSCL) are appropriate components for courses in such learning situations.
Via this approach, collaborative work situations become the core of a course. We further describe how activity theory can
provide a framework for the design of courses that involve WBA and CSCL as part of a workplace-oriented activity system for
learning. The use of this design approach for courses offered by the Learning and Leadership Development organization of Shell
International Exploration and Production is described and an example is elaborated. Finally, we identify four main issues
and challenges that arose during the use of the design approach. 相似文献

Although there are research findings supporting the positive effects of computer-supported collaborative learning (CSCL), problems have been reported regarding the learning process itself, group formation, and group dynamics. These problems can be traced back to impeded social interaction between group members. Social interaction is necessary (a) for group members to learn from each other in a CSCL environment and (b) for socioemotional processes to help create a social space where trust, sense of community, and strong interpersonal relationships exist. This article introduces a theoretical framework consisting of three core elements: sociability, social space, and social presence, along with their relationships with group members’ mental models, social affordances and learning outcomes. It postulates that the three core elements influence the social interaction needed for both learning and the emergence of a social space. This framework serves as a basis for a research agenda for systematic social CSCL research. 相似文献

CSCL环境中的社会交互 总被引：3，自引：0，他引：3
现在有很多关于计算机支持下协作学习(CSCL)异步环境中分布式学习团体(DLGs)的实证研究。研究表明当前的CSCL环境并不能完全满足人们对其支持交互的团体学习、知识共享、知识的社会建构及能力的培养的需要。在CSCL环境中,主要有两个因素阻碍我们取得预期的社会交互的成果:一是将社会交互看作是自然而然发生的,二是忽视与学习任务本身无关的社会心理交互。当前解决这个问题的办法主要是依靠教育者和教师鼓励协作学习,为了让教师从这样的负担中解脱出来,我们必须改进CSCL环境,激发和支持学习者的社会交互。 相似文献

Computer-supported collaborative learning (CSCL) environments provide learners with multiple representational tools for storing, sharing, and constructing knowledge. However, little is known about how learners organize knowledge through multiple representations about complex socioscientific issues. Therefore, the purpose of this study was to investigate learners’ knowledge organization (KO) through multiple representations in a CSCL environment. We designed a learning unit on nuclear energy and implemented it with a group of 20 college students. The participants used a web-based hypertext KO platform that incorporated three representational modes: textual, pictorial, and concept map. The platform interlinked learners’ knowledge entries based on similar keywords. Utilizing mixed methods research we analyzed the individual entries and the knowledge base to determine KO both at the individual and the collective levels. We found that the density of the knowledge base was high; the learners mostly benefited from their text- and concept map-based entries, though the picture-based entries were also an important means for connecting entries with similar content and hence creating a dense knowledge base. Our results suggest that KO with multiple representations can create a more comprehensive knowledge base. Using distinct analytical approaches will allow CSCL researchers to better identify KO both at the individual and collective levels. 相似文献

This paper reports on a study that focused on growth of understanding about teaching geometry by a group of prospective teachers engaged in lesson plan study within a computer-supported collaborative learning (CSCL) environment. Participation in the activity was found to facilitate considerable growth in the participants?? pedagogical-content knowledge (PCK). Factors that influenced growth in PCK included the nature of the lesson planning task, the cognitive scaffolds inserted into the CSCL virtual space, the meta-language scaffolds provided to the participants, and the provision of both private and public discourse spaces. The paper concludes with recommendations for enhancing effective knowledge-building discourse about mathematics PCK within prospective teacher education CSCL environments. 相似文献

This paper briefly summarizes the initial development of a computer-supported collaborative learning environment and evaluates its effects in relation to the productivity of CSCL groups. The design of the SIDE-VIEW system is driven by the social identity approach to understanding group behaviour and is premised upon the need to establish congruity between the self-definition of group members and their collaborative learning tasks. We begin by outlining the rationale for the system in relation to productivity and the emergence of team players within collaborative learning groups. We then describe aspects of the design that are intended to enhance both, and report on a field trial of the initial prototype on international groups of higher education students. The preliminary results of the field study indicate that aspects of the design encourage the emergence and influence of team players within groups, with consequential improvements to the quality of the group output. The role of team players in CSCL groups is contrasted with that of group leaders. 相似文献

The goal of this paper is to report on a meta-analysis about the effects of Computer-Supported Collaborative Learning (CSCL) in STEM education. The analysis is based on 316 outcomes from 143 studies that examined the effects of CSCL published between 2005 and 2014. Our analysis showed that the overall effect size of STEM CSCL was 0.51, a moderate but notable effect size in educational research. The effect was greatest on process outcomes, followed by knowledge outcomes, and affective outcomes. The sizes of the effects were moderated by types of technology and pedagogy, educational levels of learners, and learning domains. Moderators further interacted so that effects of technology and pedagogy varied depending on the modes of collaboration, learners' educational levels, and domains of learning. The current study demonstrates the overall advantage of CSCL in STEM education and highlights a need to understand how these variables may interact to contribute to overall CSCL effectiveness. 相似文献
