【摘要】 网络教育是建立在网络技术和计算机技术基础上，以现代教育思想和学习理论为指导，充分发挥网络的各种教育功能和丰富的教育资源优势，向教育者和学习者提供网络教学环境，以开展非面授式教育学的一种教育方式。 本文分析了网络教育的发展现状和现有网络集成教学系统的常见模式，结合我校课程教学状况，提出了现代电子技术网络集成教学系统的开发，实现了分别对应传统教育教学、复习、考试、答疑四个过程的授课辅助系统、自学辅导系统、网络考试系统和网络答疑系统。课题重点研究了网络考试系统中智能组卷的方法和实时、非实时网络答疑系统的实现途径。在建立组卷数学模型的基础上，提出两种组卷算法：面向分值的随机混合算法和遗传算法，对两种方法组卷的时间、质量进行对比、评估、分析，确定最优算法。通过现有视频会议软件和远程监控软件的集成，结合触摸屏的双端输入、显示，完成一个类似“面对面”的网络答疑系统，这是网络教学系统的创新点。 经过结构设计、算法研究、编程实现、运行调试等过程，最终实现了网络集成教学系统在局域网的试运行。运行结果表明，系统开发实现了预定目标，功能达到了预定要求。更多还原

【Abstract】 E-learning is an education mode, which is based on the web and computer technology with advanced education idea and study theory. It brings the education functions of web and education resource on web into play. Provide an environment of E-leaming to teachers and students.This item develops an Integrated Teaching System on Web of Modern Electronics Technology after analyzing the actuality of E-learning and the teaching status of Modern Electronics Technology. Four modules are including, teaching assistant, self-studying guide, exam on web and answer online. Each is corresponding to one process in traditional education of teaching, reviewing, examination and answer. The item study the methods of composing test paper of exam on web and the way to realize real-time or unreal-time answer system. Two composing test paper algorithms are raised based on the maths module: random mix algorithm on mark, genetic algorithm. Analyzes the results of these two ways to decide that when which way are used. In the answer system, integration of video meeting system and distance control system, combines with the two-in and show same time of touch display, last, realize a answer online system actually like "face to face". This is the new field of teaching system on web.The developing of this item includes system structure design, algorithms study, programming and debugging. Lastly, the whole system can run in the LAN, and the result says the developing and function aim the goals.更多还原
