基于中间件的交互式网络教学环境研究
摘要
随着网络技术,特别是Internet技术的发展和普及,网络教学已经成为远程教育的重要方式和发展方向。网络教学是将计算机和网络通信技术应用到教学领域的产物,这种新型的教学模式完全是通过网络实现的,并对整个教育结构产生了重大而深远的影响,是未来教学发展的一种趋势。网络教学系统就是为配合这种教学模式,适应教学需求发展而构建的。
论文认真分析了国内外网络教学应用的实际情况,现代网络教学的模式、特点及存在的问题。基于上述认识,论文对网络教学系统建设需求进行了分析,研究了WEB多层体系架构和中间件技术,探讨了一个基于中间件技术和B/S与C/S混合结构的网络教学系统的构建过程。该网络教学系统在J2EE平台上开发,采用了基于MVC分布式软件设计模式的WEB应用框架Struts,应用该框架,使得系统的开发层次分明,结构清晰。
该网络教学系统功能包括教师备课、课件制作、授课、学生自主学习、在线考试、师生交流、答疑等教学环节。论文以在线考试为例,详细地描述了整个模块的开发过程,系统部署,逻辑结构的设计,web表示层的设计与实现,业务逻辑的设计与实现,并论述了开发过程中的关键技术。
With the development and popularity of network technology, especially the Internet Technology, the network teaching has been the main manner and the tendency. Long-distance teaching is the result of the application of the computer and network communication technology to the whole to the teaching area. This new mode of teaching is realized fully by network, and impacts on the whole education structure. That is the tendency of the future teaching development. Network teaching system is constructed for the purpose of this kind if teaching mode and for the development of teaching need.
The paper careful analyzes domestic and international network teaching of the actual situation, the mode of teaching modern network, characteristics, and problems. Based on the above understanding, the paper research the WEB system of multi-tier architecture and middleware technology representing the construction course of the network teaching system based on middleware technology and the composite structure of the B/S and C/S, on the base of the analysis of the requirement to the network teaching system construction. The network teaching system in the J2EE platform development uses Struts framework combining Web application, based on a distributed software design pattern-MVC. By using of Struts, the structure of developing work became hierarchal.
Network teaching system functions, including teachers prepare lessons, courseware, teaching, students self-learning, online examinations, teachers and students exchanges, FAQs and other teaching. To online exam as an example, the paper detailed descript the entire module of the development process, including the logical structure of the design, arrangement of system, web presentation layer that the design and implementation, business logical design and implementation, and discussed the development of key technologies in the process.
