【摘要】：当代我国对于新课程改革和基础教学质量十分的关注,如何提高教育质量和教学水平得到社会各界的高度重视。在各项教育活动中,备课是教师教学活动的重要组成,它是学校教学中的重要环节,而且作为达到教学质量要求的重要保证手段,其在教学活动过程中的重要性自然不言而喻。随着教育理念的不断进步,其备课形式也从曾经的个人备课向集体网络备课转变,越来越多的先进技术与理念开始融入到教学实践当中。本文研究的基于协同编辑技术的网络备课系统就是将当下十分热门的协同编辑的理论和技术用于教师的备课活动当中,进一步提高教师的工作效率,完善教育的信息化过程。本文在深入了解教师备课需求和备课活动过程的基础上,将整个备课活动从任务制定到教案编写到教学实验再到协同修改的过程全部设计体现在系统当中,并从现实角度出发,将协同编辑的思想融入到整个系统中。并根据备课的实际过程细分为备课会话管理模块,教案文档管理模块,教案协同编辑修改模块等。其中,重点设计了协同编辑修改模块,从协同感知,版本控制和一致性算法维护等具体方面解决了教案协同编辑修改时存在的一系列如并发冲突、感知不足、教案版本错乱等问题,设计了一个能够实现多人实时在线协同编辑的专业教师网络备课系统。为了检验本文的设计理念,论文最后还初步实现了一个基于Web的协同网络备课系统,从实现角度有分别对备课过程管理模块、教案文档管理模块和协同编辑模块的详细设计与实现问题进行了进一步论述。在具体的实现过程中,综合多方面因素考虑后决定整个系统采用B/S模式,将JavaEE技术和B/S三层结构模型相结合,采用包括前端网页技术(HTML技术+CSS技术+JavaScript技术)、后端服务器技术(JavaWeb相关技术)和数据库技术基本实现了一个可用的Web端的协同编辑网络备课系统,并通过使用身份验证、数据绑定等手段,使系统的安全性和易维护性得到了提高,也让系统界面更加简洁,重点突出。
[Abstract]:In contemporary China, great attention is paid to the new curriculum reform and the quality of basic teaching. How to improve the quality of education and the level of teaching has been attached great importance to by all walks of life. In all kinds of educational activities, preparing lessons is an important component of teachers' teaching activities, it is an important link in school teaching, and as an important means to meet the requirements of teaching quality, its importance in the process of teaching activities is naturally self-evident. With the continuous progress of educational ideas, the form of preparing lessons has also changed from personal preparation to collective network preparation. More and more advanced technologies and ideas have been integrated into teaching practice. The network lesson preparation system based on collaborative editing technology studied in this paper is to apply the theory and technology of collaborative editing to teachers' lesson preparation activities in order to further improve the efficiency of teachers' work and improve the information process of education. On the basis of deeply understanding the teachers' requirement of preparing lessons and the process of preparing lessons, the whole process of preparing lessons from task making to teaching plan compiling to teaching experiment to collaborative modification is embodied in the system, and from the point of view of reality, the whole process of preparing lessons is embodied in the system. The idea of co-editing is integrated into the whole system. According to the actual process of preparing lessons, it can be divided into two modules: session management module, teaching plan document management module, teaching plan editing module and so on. Among them, we focus on the design of collaborative editing modification module, from the aspects of collaborative awareness, version control and consistency algorithm maintenance and other specific aspects to solve a series of concurrent conflicts existing in collaborative editing and revision of teaching plans. In this paper, we design a multi-person online online collaborative editing system for professional teachers' online lesson preparation. In order to test the design idea of this paper, a collaborative network lesson preparation system based on Web is implemented in the end of this paper. The detailed design and implementation of teaching plan document management module and collaborative editing module are further discussed. In the concrete realization process, after considering various factors, the whole system adopts the B / S mode, combining JavaEE technology with the B / S three-layer structure model. In this paper, a collaborative editing network lesson preparation system based on Web and database technology is implemented, which includes front page technology, HTML technology, JavaScript technology, back-end server technology and Java web related technology, and it is verified by the use of authentication. Data binding improves the security and maintainability of the system, and makes the system interface more concise and focused.
