【摘要】：近年来,随着移动智能设备的普及和移动通信技术的发展,移动学习日益成为现代社会一种重要的学习形式。移动学习的明显优势在于不必拥有固定的地点和特定的时间,能够依据学习者的学习需求随时随地开展,也为教师提供了多样化的教学手段和方式。交流讨论是学习的重要环节,也是移动学习平台的一个重要功能,其中,师生或生生同时在线的同步交流讨论尤为重要,通常采取实时图文消息、音视频会话等交互方式以应对。然而,目前移动学习平台中的交互方式与学习过程及学习资源并无直接关联,不能有效的适应面向学习的交流讨论。一方面,在资源学习过程中,学习者遇到疑难知识点,要切换页面才能进行交流讨论,这样不利于学习者对知识背景的描述,另一方面,由于相似资源没有进行关联,学习者发起的交互讨论只能在小范围进行,并且参与交互的人员并不一定具有该课程的知识背景,无法实现有针对性、高效的同步交互,这样势必很大程度地制约移动学习同步交互的开展。本文针对这些问题,鉴于移动学习的固有特性,设计了基于资源关联的移动学习同步交互系统。通过整理课程关键词,研究课程内容以及课程关键词之间的内在联系,搭建课程语义数据库;通过研究学习者与学习资源间的关联关系,构建学习者-学习资源二部关联图,生成交互成员匹配列表,而后依据多个维度指标对交互成员进行推荐;通过研究标注信息与交互信息的呈现方式,实现资源标注和交流信息动态焦点关联呈现;通过研究与学习资源关联的交互信息、相关属性和主体内容,实现交互信息关联学习资源的长久存储。本文依托华大移动学堂平台对实现的系统进行了功能测试和性能测试。功能测试主要通过对系统的各个模块分别进行测试,观察各个模块的功能是否达到需求分析中设定的要求。性能测试主要记录平台运行过程中的各项性能指标,并分析这些性能指标是否处于正常范围。测试结果显示,各个功能模块均能达到预期设计的要求,性能测试的指标结果均在可接受的范围内。
[Abstract]:In recent years, with the popularization of mobile intelligent devices and the development of mobile communication technology, mobile learning has become an important learning form in modern society. The obvious advantage of mobile learning is that it does not have to have a fixed place and a specific time, it can be carried out anytime and anywhere according to the learners' learning needs, and it also provides a variety of teaching methods and methods for teachers. Communication and discussion is an important part of learning and an important function of mobile learning platform. Audio and video conversations and other interactive ways to deal with. However, there is no direct relationship between the interaction mode of mobile learning platform and learning process and learning resources, so it can not effectively adapt to the learning-oriented communication and discussion. On the one hand, in the process of resource learning, learners encounter difficult knowledge points, and they have to switch pages to communicate and discuss, which is not conducive to the learners' description of the knowledge background. On the other hand, because the similar resources are not related to each other, The interactive discussions initiated by learners can only be conducted on a small scale, and the people involved in the interaction do not necessarily have the knowledge background of the course and cannot achieve targeted and efficient synchronous interaction. This is bound to restrict the development of mobile learning synchronization interaction to a large extent. In view of the inherent characteristics of mobile learning, a synchronous interactive system for mobile learning based on resource association is designed in this paper. Through sorting out the curriculum keywords and studying the internal relationship between the curriculum content and the curriculum keywords, the course semantic database is set up. By studying the relationship between learners and learning resources, we construct a learner-learning resource bipartite association graph, generate a matching list of interactive members, and then recommend interactive members according to multiple dimension indicators. By studying the presentation of annotated information and interactive information, the dynamic focus presentation of resource annotation and exchange information is realized. The long-term storage of learning resources is realized by studying the interactive information, the related attributes and the main content of the learning resources. This paper carries on the function test and the performance test on the platform of Huadu Mobile School. The function test mainly through the system each module carries on the test separately, observes each module function whether meets the requirement which sets in the demand analysis. The performance test records the performance indexes of the platform and analyzes whether the performance indexes are in the normal range. The test results show that each functional module can meet the requirements of the expected design, and the performance test results are within the acceptable range.
