mCSCL环境下协作分组的伙伴模型研究 总被引：1，自引：0，他引：1
mCSCL正在成为移动学习新的研究热点,协作小组是开展mCSCL活动的基本单元,如何寻找协作分组中的学习伙伴是当前需要研究的一个重要问题,而设计并建立协作分组的伙伴模型是寻找学习伙伴的第一关键所在.伙伴模型能够对学习者进行建模,通过它能够为mCSCL的协作分组提供选择依据.本文在分析伙伴模型研究现状的基础上,综合学习者个性特征和mCSCL中学习的特殊性构建了mCSCL环境下协作分组的伙伴模型. 相似文献

为了提升成人学习者的网络学习质量,该研究将引领式教学、基于任务的学习和小组协作学习理论引入网络学习环境的设计中,以"引领""任务"和"协作"作为功能模块的设计核心,搭建了基于任务的引领式协作学习环境,实现了教师对成人学习者的学习进度、学习目标、学习内容和讨论协作等全方位的引领,还原了传统课堂的有序教学及师生、伙伴间的有效协作。为了验证在此环境下开展教学的效果,研究团队以"网页设计"课程为例进行了教改实践。通过分析调查问卷数据,证实了在基于任务的引领式协作学习环境下开展教学,能帮助教师进行学习过程监控,减低学习迷失率,促进学习者开展有目的的学习,值得在成人学习者的课程网络教学中尝试及推广。 相似文献

Web协作学习可以消除网络学习的孤独感,发挥群体能动性,提高学习效率.然而,基于交流论坛的协作学习,由于参与者学习行为的独立随意性,不适合协作经验不足和自主学习能力较弱的学习者.而将面对面协作学习远程化的协作学习,由于网络环境下师生数量悬殊过大,不具备推广性和普适性.在缺乏教师实时监督指导的现实前提下,基于工作流技术,笔者提出构建一种适合网络学习者自行实施协作学习的Web协作学习环境.该环境提供学习流以引导学习活动的有序开展,并将协作教学管理经验作为协作学习策略进行存储,监控可能出现的协作困难并提供解决方案.学习者通过遵循Web协作学习环境定义的各项规则,激发学习能动性,提高Web协作学习的有效性. 相似文献

学习分组是协作学习活动设计的首要阶段。随着学习场所的快速变化、多模态交互过程复杂性的增加,采用传统的随机分组、教师指派或学生自我选择等方法进行协作学习分组的效率十分低下。研究提出基于智能技术构建自适应的协作学习小组。首先,阐述了学习分组的价值,即构建合理的协作学习环境、兼顾学生的个体差异和促进教育资源优质公平;其次,总结了影响智能学习分组的因素,包括个体属性、小组学术与物理构成以及学习者与环境的交互;最后,描述了经典场景下智能学习分组的通用模型,并讨论了大数据背景下智能学习分组的前景与挑战。针对大数据驱动智能学习分组的稳定性问题,基于机器学习中的集成学习思想构建了大数据共识分组框架。此框架有望为人工智能促进未来规模化的个性化教育提供支持。 相似文献

Past research has pointed out that a good grouping strategy can improve the learning effectiveness of collaborative learning. However, the grouping strategy adopted in most past research is static grouping. This results in some disadvantages. Therefore, this study developed an item bank-based collaborative practice system and proposed a dynamic grouping method which uses the concepts of weighted quizzes and bit coding as the rule of a regrouping algorithm. The method and the traditional static method were applied to two classes of sophomore students of a university of science and technology in the central region of Taiwan. There were 76 valid samples which included 38 students of the experimental group and 38 of the control group. The control group adopted the static grouping method, and the experimental group adopted the dynamic grouping method. The experimental duration was 9 weeks of 3 hours per week. Experimental results showed that the collaborative experience value and the learning effectiveness of the experimental group were significantly greater than those of the control group. This indicates that the experimental group students made more efforts to conduct coordination, discussion and finally reach consensus with their partners, and made greater progress than the control group students. 相似文献

提出了一种基于多属性分类的KNN改进算法,可有效提高传统的欧几里德KNN算法和基于信息熵的KNN改进算法的分类准确度。首先,按照单个属性不同属性值的个数占整个属性包含样本的比例进行属性的分类,分为基于信息熵的KNN算法处理的离散属性和基于传统欧几里德KNN相似度处理的连续属性两类,然后分别对不同属性进行区别处理;其次,将两类不同处理后得到的结果按比例求和作为样本之间的距离;最后,选取与待测样本的距离最小的k个样本判断测试样本的决策属性类别。 相似文献

This paper reports the results of an exploratory study on participants’ perception of the importance of single‐gender grouping in a massive open online course (MOOC) delivered through the Coursera platform. Findings reveal that female and male learners’ perception of single‐gender grouping differs. Female students more than males indicated less preference for single‐gender grouping. Views on single‐gender grouping also differed across regions, suggesting the effect of participants’ regions of origin on their opinions about single‐gender grouping. Moreover, an interaction was established between participants’ region and gender. In particular, our study reveals that men in the “Asia and Pacific” region tended—more than men and women from other regions of the world—to give more importance to single‐gender grouping in this MOOC. In addition, younger participants cared less about single‐gender groups compared to older respondents. This study sheds light on our understanding of the importance of gender and age importance in online learning environments such as MOOCs. The findings also point to the role gender and age may play as MOOCs continue to gain in popularity and to adopt collaborative approaches to teaching and learning. 相似文献

The purpose of this study was to examine the importance of cooperative incentives and heterogeneous grouping as elements of cooperative learning in a college life science course. Cooperative learning may be defined as a classroom learning environment in which students work together in heterogeneous groups toward completion of some task. Cooperative incentive structures provide some type of group reward based on group products or individual learning. In heterogeneous grouping, students are arranged in order to maximize variety within groups. A 2 × 2 design was utilized in this study. The independent variables considered included (a) use of cooperative incentives in learning groups, and (b) use of heterogeneous grouping in cooperative learning groups. Dependent variables for all treatment groups were scores from a multiple-choice instrument developed for an earlier, related study, along with direct observational data on frequency of cooperative interactions. Analysis of covariance (ANCOVA) was used as the data analysis procedure for the achievement portion of the study, and analysis of variance (ANOVA) was used for analysis of the cooperative interaction portion of the study. No significant differences were found between the treatment groups. 相似文献

在协作学习中学习投入与学习成效紧密相关,是学生进行有效参与和深度学习的必要条件。但目前的研究大多针对个人学习投入,缺乏在协作学习中小组学习投入的相关研究。在前人研究基础上,本研究从认知投入、行为投入、社会投入、情感投入四个维度构建了在线协作学习中小组学习投入的分析模型,并通过实证研究进一步探索小组投入分析模型各维度与小组学习成绩之间的关系。结果表明,在小组学习投入中行为投入、社交投入与小组成绩呈显著正相关关系,而积极、消极、困惑三类情感投入则与小组成绩呈负相关关系。研究同时发现,高分组在中立情感投入、认知投入的问题和元认知维度中的均值都高于低分组。最后,通过分析在线小组学习投入与成绩之间的关系,为今后优化学习支持服务以及提高小组成员协作质量提供了依据。 相似文献

Critical thinking (CT) and English literacy are two essential 21st century competencies that are a priority for teaching and learning in an increasingly digital learning environment. Taking advantage of innovations in educational technology, this study empirically investigates the effectiveness of CT‐infused adaptive English literacy instruction using a Moodle system. A one‐group pretest–posttest design was employed to evaluate the effect of the treatment on students' acquisition of CT skills (CTS) and English literacy. A total of 83 students enrolled in two sections of a general studies course at a large university in Taiwan participated in the semester‐long experiment. Adaptive learning was achieved through the use of an online Moodle system for (1) online grouping (based on pretest English literacy scores), (2) delivery of specifically designed adaptive learning materials for each group and (3) provision of individualised feedback. CT‐infused language activities based on social constructivist principles were designed for each level of adaptive instruction, whereas direct instruction for fostering CTS was provided in class and practiced or reflected upon in groups. Empirical results demonstrate that CT‐enhanced adaptive English literacy instruction simultaneously improved students' CTS and English literacy and that students' online discussions developed towards higher levels of interaction. This paper illustrates an effective blended learning model for adaptive instruction and offers recommendations for designing CT‐infused language learning activities that can successfully foster both CT and English literacy outcomes. 相似文献
