【摘要】：近些年,国家积极倡导教育教学与信息化技术相融合,推进教育改革与创新。在教育信息化的背景下,以移动学习为首的非正式学习异军突起,成为了一种重要的学习方式。许多学者积极投身于移动教育平台构建,不断完善移动学习资源的开发。然而,现有移动学习平台忽略了学习者有限认知水平与海量资源间的矛盾,导致学习者认知负荷过重,无法及时消化所学内容。因此,有必要引入合理的笔记模式,梳理和串联知识脉络,构建清晰完整的知识体系。在实际应用中,纸质笔记由于编辑低效,不易管理等缺点,逐渐被移动交互式笔记所替代。移动交互式笔记作为独立应用,并不依托于移动学习平台,无法建立与学习资源、其他笔记间的有效关联,难以获得直观的学习感受,从而影响学习效果,因此需要针对移动学习情境设计专属的学习笔记功能。为了解决移动学习情境下,学习笔记功能存在关联性差、笔记利用率低的实际问题,本文设计实现了一款适用于移动学习平台的关联笔记系统。论文的主要工作包括:首先,基于相关理论及技术分析,研究了笔记与资源、笔记与笔记间的关联策略。其中,通过关联建立方法、关联呈现机制、组织管理策略研究,建立笔记与资源间的关联机制和资源关联的笔记存储模型。此外,采用基于语义的标签关联策略判断笔记间的关联性,构建关联推荐机制,实现了学习者之间的笔记共享。其次,根据上述策略,设计了移动学习平台关联笔记系统的客户端、服务端及数据库架构,完成了笔记数据同步、关联呈现、组织管理、关联推荐四大模块的功能实现。最后,依托于华大移动学堂,正式上线运行关联笔记系统,并进一步开展功能测试、性能测试、应用数据测试,多方面验证了系统的有效性及可靠性。论文创新之处在于构建适用于移动学习情境下的新型笔记模式,实现学习者与课程资源、知识内容间的深度交互,从而有效提高学习效率。
[Abstract]:In recent years, the state actively advocates the integration of education and teaching and information technology to promote educational reform and innovation. Under the background of educational informatization, informal learning, led by mobile learning, has become an important learning method. Many scholars actively devote themselves to the construction of mobile education platform and constantly improve the development of mobile learning resources. However, the existing mobile learning platform ignores the contradiction between the limited cognitive level of learners and massive resources, which results in the learners being overloaded with cognition and unable to digest what they have learned in time. Therefore, it is necessary to introduce a reasonable note-taking model to sort out and concatenate the knowledge context and construct a clear and complete knowledge system. In practical applications, paper notes are gradually replaced by mobile interactive notes because of the shortcomings of inefficient editing and difficult management. As an independent application, mobile interactive notes do not depend on mobile learning platform, and can not establish effective relationship with learning resources and other notes, so it is difficult to obtain intuitive learning experience, thus affecting the learning effect. Therefore, it is necessary to design a special learning note-taking function for mobile learning situations. In order to solve the practical problems of poor relevance and low utilization of notes in mobile learning environment, this paper designs and implements an associated note-taking system suitable for mobile learning platform. The main work of this paper includes: firstly, based on the theoretical and technical analysis, the paper studies the strategies of the relationship between notes and resources, notes and notes. Among them, through the association establishment method, the association presentation mechanism, the organization management strategy research, establishes the note and resource association mechanism and the resource association note storage model. In addition, the semantic based label association strategy is used to judge the relevance of notes, and the associated recommendation mechanism is constructed to realize the sharing of notes among learners. Secondly, according to the above strategy, the client, server and database architecture of the mobile learning platform association note system is designed, and the four modules of note data synchronization, association presentation, organization management and association recommendation are implemented. Finally, relying on the Huadu Mobile School, formally running the related note system, and further developing the function test, performance testing, application data testing, the effectiveness and reliability of the system are verified in many aspects. The innovation of this paper is to construct a new note-taking model suitable for mobile learning, to realize the deep interaction between learners and curriculum resources and knowledge content, so as to effectively improve the learning efficiency.
