Research on Application of Data Mining in Virtual Community of Foreign Language Learning

The construction of virtual community in foreign language learning is a comprehensive foreign language learning environment integrated with foreign language vocabulary database construction and vocabulary retrieval, combining the virtual reality technology to construct the language environment of foreign language learning. The virtual community of foreign language leaming can improve the sense of language authenticity in foreign language learning and improve the quality of foreign language teaching. A method of building a virtual community for foreign language learning is proposed based on data mining technology, data acquisition and feature preprocessing model for building semantic vocabulary of foreign language learning is constructed, the linguistic environment characteristics of the semantic vocabulary data of foreign language learning is analyzed, and the semantic noumenon structure model is obtained. Fuzzy clustering method is used for vocabulary clustering and comprehensive retrieval in the virtual community of foreign language learning, the performance of vocabulary classification in foreign language learning is improved, the adaptive semantic information fusion method is used to realize the vocabulary data mining in the virtual community of foreign language learning, information retrieval and access scheduling for virtual communities in foreign language learning are realized based on data mining results. The simulation results show that the accuracy of foreign language vocabulary retrieval is good, improve the efficiency of foreign language learning.

虚拟学习社区中自主学习活动研究:元认知视角

元认知包括对认知的知识、认知的体验和认知的监控及调节三个方面,其核心思想是对认知过程的自我调节。学习不仅仅是认知过程,同时也是对该认知过程进行积极监控及调节的元认知过程。元认知被认为是自主学习的关键过程,是促进学习的关键要素。虚拟学习社区(简称VLC)中的自主学习活动是其学习活动的核心内容之一,是其他学习活动(如协作学习活动)开展的基础。文章从VLC、元认知和学习的内部心理机制及规律出发,研究元认知视角下的VLC中自主学习活动和学习环境设计,提出了VLC中自主学习活动的元认知调控内部循环过程模型和基于元认知的自主学习活动过程模型以及基于元认知和自主学习活动的VLC学习环境功能模型。

基于信息空间的虚拟共同体协作知识建构分析

在现有虚拟学习共同体知识建构研究的基础上,从信息空间的视角,分析虚拟学习共同体中复杂知识的分布,依托知识分布情况,分析共同体中学习群体协作学习时知识获取、传播等建构过程,并结合开放性实验等实践教学活动提出促进虚拟学习共同体知识建构的管理策略。

基于建构理论的高校虚拟学术社区研究

文章基于建构理论,阐述了高校虚拟学术社区学术共享的组成要素,探讨了高校虚拟学术社区的建设原则,对我国高校符合建构理论的虚拟学术社区进行应用实例分析,对高校虚拟学术社区研究有很强的现实意义。

社交媒体在虚拟学习共享空间的应用研究

[目的/意义]将社交媒体应用于高校图书馆虚拟学习共享空间,探索其助力虚拟学习共享空间快速发展的有效途径,以践行图书馆服务由"以信息资源为中心"向"以学生学习为中心"的转变。[方法/过程]设计以QQ、微信等大学生喜爱善用的在线交流媒体为工具,以"学生服务团队"、主题驱动、多方协同、用户评价等为要素,构建、组织、管理虚拟学习共享空间的机制,并将这种机制应用于一个以"汽车"为主题的虚拟学习共享空间进行了实践研究。[结果/结论]实证研究和用户评价表明,以社交媒体作为工具构建高校图书馆虚拟学习共享空间,适合当下大学生个性化学习的需求;优化"学生服务团队"是其有效运行的关键因素;主题驱动和多方协同提升了其吸引力及其内涵,大学生学习成效显著,参与踊跃。
