【摘要】 随着移动终端和互联网通信技术的普及与成熟,基于移动平板电脑的电子书应用开始进入日常的教学活动中。然而现有多数电子书只是对纸质内容的数字化,通过相应功能提高电子书的阅读使用体验,针对电子书在师生教学过程使用、提高电子书教学性和学习性的功能研究和设计比较薄弱,导致电子书在教学使用过程中提高教学效果的作用并不明显,迫切需要根据实际教学需求而设计的新型电子书。因此,本文设计并实现了学习型电子书(系统),直接定位于教学使用,来帮助教师和学生提高教学效率和教学效果。本文研究和设计了学习型电子书系统,依据软件工程相关理论和方法进行如下工作。首先进行学习型电子书需求分析,概述了教育软件需求获取特点和方法,以此为基础总结了国内外现有研究和系统的特性和局限性,论述了相关的理论和技术问题。同时,依据教育软件需求特点,分析了相关角色、教学场景、教学内容和教学方法设计,在上述基础上进行需求抽取获得功能性需求和质量需求。其次,结合需求分析和技术选型,确定了系统的整体架构和功能模块设计划分,并设计了客户端非关系型数据库的数据结构和客户端-服务器数据通信接口API。再次,依据学习型电子书应用场景特点,对教材内容组织和内容标记设计、内容全文检索两个问题进行深入的探讨并给出解决方案。最后,在系统设计的基础之上结合技术选型和相关开发工具对学习型电子书整体架构和客户端主要功能模块进行实现,完成了主内容区内容导航、数据本地存储及数据同步、内容标记题型、全文检索四个主要功能模块的实现。本文提出了学习型电子书的功能定义,完成了学习型电子书系统的研究与设计,过程中解决了学习型电子书教材内容组织和内容标记设计及全文检索功能设计。本系统已在几所高中试点使用,教学效果良好,具有较强的应用前景和研究意义。更多还原

【Abstract】 With the maturity and popularity of mobile devices and Internet technology, e-book began to enter daily teaching activities. However, most existing e-book just digitizing the paper-based content, and improve the reading experience through the appropriate function. Few studies about e-book for teacher and students to use in the teaching pro-cess and to improve the character of teaching and learning of e-book. It led to the improvement of teaching effect by the use of e-books is not obvious. So it need a new e-book designed for teaching requirement. Therefore, this paper designs and imple-ments learning-oriented e-book software system.It is targeted at educational use to help teachers and students to improve teaching effectiveness.This paper focuses on the research and design of learning-orented e-book software system. Based on the development process of software to carry out the following work. Firstly, this paper introduced the requirements analysis of the system. Overview of the characteristics and methods of educational software requirements, on this basis sum-marizes the features and limitations of the existing domestic and international research and systems, and discusses the relevant theoretical and technical issues. Meanwhile, according to the characteristics of educational software, this paper analyze the relevant role, teaching scenes, teaching content and teaching methods designed. Based on the above description, this paper extract the functional requirements and quality require-ments of the system. Secondly, determine the overall structure and module design by the combination of requirements analysis and technology selection, design the client side data structures of no-sql databases and communication API. Thirdly, based on the characteristics of e-book application scenarios, the rules of content organization and definition and full-text retrieval has been solved. Finally, achieved the overall archi-tecture and the client side’s main function modules, including navigation of Content、 client side local data storage and data synchronization、the rules of content definition、 full-text retrieval.This paper presents a functional definition of learning-oriented e-book, and com-pleted the research and design of learning-oriented e-book. Meanwhile, this paper solve the rules of content organization and definition and full-text retrieval. The system has put into use in several middle school, and it obtained good teaching effect. It has a wide range of prospect and significance.更多还原
