远程学习者异步交互的行为方式和特点 总被引：12，自引：3，他引：12
异步交互方式是目前远程教学中应用相当广泛的一种教学交互的实现形式,由于远程教学中师生分离的特点以及异步交互的非实时性特点,学习者在利用这种交互形式进行远程学习时,能否实现预期的较高水平的交互效果以及这种交互模式下学习者的活动的方式和特点都应该引起我们的重视。本文以异步交互中的远程学习者为研究对象,以远程学习中的教学交互模型为理论基础,主要研究了远程学习者在异步交互中的主要活动方式,以及实现的教学交互的特点。文章通过访谈法、问卷法重点分析了异步交互活动中的“观望者”和“参与者”在远程学习过程中所实现的教学交互方式上的差异。最后指出,在异步交互中,远程学习者的参与形式和参与程度是影响教学交互的重要因素。作者希望本研究能够帮助读者进一步认识教学交互过程中学生行为的差异和特点。 相似文献

在"互动假说"的理论框架下讨论移动学习模式运用于语言形式学习的可行性,发现移动学习模式可以灵活运用文本的编排功能,以及图片、音频和视频等多种媒介进行强化型和结构型输入,能够在促进学习者理解意义的同时将其注意力吸引到语言形式上,比教材中单一的文本型输入更加灵活有效。基于网络的移动学习平台不受时间、空间和课堂环境下干扰因素的影响,可以为学习者提供更多、更自由的交流互动机会,当交流以目标语作为媒介时,学习者能够更容易关注到语言形式。移动学习平台为学习者提供了口头和书面输出语言的机会,通过双向交流和集体协作的互动模式可以有效地提高学习者口语化输出和正式文体输出的能力。 相似文献

异步交互中远程学习者教学交互水平的研究 总被引：11，自引：1，他引：11
远程教育领域的许多研究发现,在各种同步或异步的教学交互过程中,存在着大量的观望者,他们并没有积极参与教师组织的教学交互活动,只是”旁观”其他学习者的教学交互。研究者和实践者开始关心是否所有的远程学习者都能够通过精心设计的教学交互活动,实现有效的学习。本文以远程学习中的教学交互模型为理论基础,分别利用Bales的交互过程分析法和及Gunawardena的基于建构主义的线索解析模型,对比研究了异步交互活动中的“参与者”和“观望者”在异步交互中教学交互水平。同时,作者结合异步教学交互中学习者的交互形式以及活动特点,分析了造成这两类学习者教学交互水平差异的主要原因。 相似文献

近年来,教育界利用计算机辅助学习呈改变的趋势:越来越多的面向学习的应用程序都将其重心从以官方开发(即:资源提供者或者教育工作者)的学习平台转向以学习者为中心的学习平台。提出了由学习者自主订阅学习资源甚至开发各自的个性化学习环境,将通过iGoogle个人门户平台来构建个性化学习环境。其包括了提供能够支持各个系统之间的协作以及个人学习活动的网络应用软件以及服务。在很大程度上改变了单一的灌输式学习资源获取,为学习者提供了一个可以创造个性化学习环境的平台。通过与学校资源的共享,教育工作者与学生之间,学习者与学习者之间,可以通过此环境进行协作性交流学习。 相似文献

Over the last years there has been a growing use of 3D virtual environments for educational purposes. Many studies advocate the integration of these environments in the daily teaching practice of various subjects. This requires innovative design in order create the appropriate affective/ pedagogical conditions as well as the development and use of well-structured activities in order to achieve effective collaborative learning. This paper presents an exploratory study in which collaborative learning strategies and cognitive apprenticeship models act as the pedagogical framework to facilitate learning and collaboration. The context is the teaching of mathematics in primary education via a 3D virtual environment. Specifically, we focus on evaluating students’ engagement (behavioral, affective and cognitive) in the collaborative learning process as they learn fractional concepts in a meaningful way. The findings show that a 3D virtual environment can support collaborative learning in primary school through its ability to enhance students’ engagement (behavioral, affective and cognitive) in the collaborative learning process. 相似文献

Abstract This article discusses the design, development, and implementation of a collaborative learning environment for online training ‘Infoshare on the Web’ It was designed to teach participants how to use and/or improve their use of Web search engines to access information on the Web. Participants collaborated in completing group tasks using asynchronous communication provided by Simon Fraser's Virtual‐U, a Web‐based environment that supports distance education, information sharing, and training. The module was delivered in four weeks, and participants found both advantages and limitations in the use of asynchronous environments for training. 相似文献

The paper reports on an empirical study adopting a mixed research method, aiming at improving primary students’ collaborative problem solving competency in project-based learning with productive failure (PF) instructional design in a seamless learning environment. Two Grade Six classes participated in a project-based learning of “Plant Adaptations”. In Class 1 with 27 students, the project-based learning was conducted with PF instructional design; in Class 2 with 26 students, the project-based learning was conducted without PF instructional design. The learning activities spanned across farm, class, home and online spaces supported by mobile devices. Data collection includes various students’ created artifacts in groups in the inquiry process, student reflections, student focus group interviews and pre- and post-domain tests. Both qualitative and quantitative data analysis methods were employed. The research findings show that compared to Class 2, the students in Class 1 gained deeper understanding of conceptual knowledge and produced better group artifacts in collaborative problem-solving quality than those in Class 2; and the students in Class 1 were more positive in facing the challenges in their project-based learning process, and developed a sense of ownership of their learning. The findings imply that PF instructional design is conducive to developing primary students’ collaborative solving competency in science learning in a seamless learning environment. 相似文献

This study investigates student interactions in a blog-based learning community in a university course. In addition, this study explores the dynamics of group interactions in individual blog-based environments compared with collaborative wiki-based educational activities. A learning community of 56 graduate students wrote individual blogs and weekly group summaries using a wiki environment. The posts were analyzed by identifying a post content type and explicit feedback promotions, and by counting the number of the blogger's own comments and the number of others’ comments per post, received from peers studying in the same versus the other offline group. The results show that choosing the appropriate type of post content (i.e., sharing experiences rather than providing information, explicitly calling for feedback, and providing the blogger's own comments) augments peer interaction in a blog environment, thus explaining 51.4% of variance in peer comments. Group interactions through comments in individual blogs, without the possibility of changing one another's content, seem to be non-intrusive and prompt interactions with offline as well as with online peers. In contrast, actual editing of texts through multi-authored collaborative wikis remained affected by student offline former acquaintance. The results are discussed in terms of social interactions and pedagogical beliefs. 相似文献

In this study, we argue that a teacher has a crucial role in leading students into collaborative inquiry‐learning practices. While many studies have given the impression that students are able to engage in inquiry processes on their own, the role of social practices and teacher guidance often remains unexplained. However, even when the pedagogical setting is organized toward collaboration and student‐driven inquiry, it does not mean that students will, as a matter of course, collaborate and take collective responsibility for their own learning. This research has been conducted by a teacher and researchers, and reports on the teacher’s impressions about organizing and promoting a computer‐supported collaborative inquiry process in her classroom of the fourth and fifth grade levels of a Finnish elementary school. The ‘Artifact Project’ was collaboratively designed together by the class teacher and researchers, but the teacher was responsible for implementing and adapting plans in practice. The aim of the ‘Artifact Project – the Past, the Present, and the Future’ – was to support students’ (n = 32) understanding of the diversity of artifacts. Students were asked to analyze artifacts within the cultural context, to study physical phenomena related to them, and to design future artifacts. A collaborative learning environment, Knowledge Forum, facilitated the activities. During the process, the teacher wrote weekly in a reflective project diary. The template of the diary guided the teacher to reflect on the issues that she considered important at the writing moment: the organizing practices, topic content and process stages; how the classroom community functioned; as well as the role of technology as a support for the process. The contents of the diary were analyzed with qualitative content analysis with the help of AtlasTi software. This study depicts an experienced teacher’s practices, her efforts to promote pupils’ cognitive responsibility for advancing their collaborative object‐oriented inquiry process themselves. Instead of trying to control all aspects of pupils’ learning, the teacher assumed the role of an organizer concerning collaborative progressive inquiry and designing activities. Organizing and supporting activities were based on a continuous following of the pupils’ states of process. Knowledge Forum structured the process and mediated activities, and rendered their objects visible and accessible to the whole learning collective. We suggest that in order to expand and scale up advanced inquiry practices, teachers’ usually invisible work in guiding and directing classroom practices has to be made visible and should be analyzed in detail. 相似文献

Trying to understand the complexity of computer-mediated problem-based learning environments is not easy. Sociocultural theory provides a theoretical framework for understanding such environments because it emphasizes the socially situated nature of learning and the critical role of tools in mediating learning. To examine how different aspects of discourse relate to each other, as well as to the tools being used in the collaborative learning process, it is important to understand how collaborative knowledge building unfolds and how these processes are mediated. This requires going beyond coding individual speech acts. The use of Chronologically-Ordered Representations of Discourse and Tool-Related Activity (CORDTRA) diagrams is one way of achieving this understanding. We use this to study contrasting cases of more and less successful groups using the STELLAR learning environment. STELLAR is an integrated online PBL environment for preservice teachers, containing a learning sciences hypermedia, a library of videocases, and online personal and collaborative spaces. Our analyses suggest that an important locus of differences is how students use resources and engage in different kinds of metacognitive talk and knowledge transforming activities, sometimes to the group’s detriment. Frequency analyses provided an easily interpreted snapshot of each group’s activity. The CORDTRA analyses provide a more dynamic view that helps researchers and teachers better understand how collaborative learning unfolds. Such analyses have implications for understanding new learning environments as well as helping identify where interventions might be needed. 相似文献

When inquiry-based learning is designed for a collaborative context, the interactions that arise in the learning environment can become fairly complex. While the learning effectiveness of such learning environments has been reported in the literature, there have been fewer studies on the students’ learning processes. To address this, the article presents a study of science learning in a computer-supported learning environment called Collaborative Science Inquiry (CSI), which integrates guided inquiry principles for activity design, employs modelling and visualisation tools for promoting conceptual understanding and incorporates key computer-supported collaborative learning (CSCL) elements for enabling students’ collaboration. With the aim of understanding the process of students’ conceptual changes supported by the CSI learning environment as used in a secondary school, data on students’ test achievements, responses to learning tasks and peer discussions in collaboration were collected, analysed and discussed. The results of the qualitative and quantitative data analysis indicated that guided inquiry coupled with CSCL elements facilitated by the CSI system can engage students in inquiry activities and promote their conceptual understanding in a progressive way. 相似文献

Today, ICT, web resources and multimedia contents have become prevalent in Malaysian university classrooms; hence, the learning approaches need to be redesigned for enabling students to use these technologies in co-constructing new meaning. This study analyses student’s perception and their peer interaction in the constructivist–collaborative learning environment (CCLE) with multimedia contents and Web 2.0 tools, to address the research question: What is the impact of CCLE on student learning process? By using factor analysis on the questionnaire results, and applying content analysis on students’ comments in Web 2.0 tools and feedback given by 182 students at INTI International University, several components of constructivist–collaborative learning were identified. The discussion in this study focuses on “team” and its sub-components include group dynamics, students’ prior knowledge with team and group processing. The discussion provides more understanding on the impact on student learning process for enhancing the learning experiences in Malaysian university class environment. 相似文献
