摘要
随着世界信息技术的飞速发展,远程教育和传统教育已不再是两个界限分明的世界,而是趋于相互融合。“尺有所短,寸有所长”,人们发现远程教育和传统教育各自有各自的优势,综合起来起运用则会达到最佳效益。
对于远程教育而言,必然要依托于传统教育才能正常运作。而对于传统教育而言,我国约80%的高校已经建设了校园网,校园网在日常教学中逐渐发挥出巨大的作用,远程教育的某些应用在传统校园中逐渐流行,对原有的教学模式产生的冲击日趋明显。
本次所开发的基于Web的在线实时考试系统就是远程教育在传统教育中应用之一。它打破了原有的考试模式,利用现有的网络资源构架出一种新的考试平台。简化了原有考试中一系列复杂的操作,使得学生能够便捷的参加各种测试或考试,不再受到任何时空的限制。
本文首先从总体上概述了在线实时考试系统的整体框架,对系统进行了准确的定位。
然后,本文描述了系统的总体设计方案,为系统的实施进行了合理的分析和设计。
在此基础上,介绍了在设计开发的过程中所遇到的问题及其解决的方案。
其次,又分别概述了为系统所采用的各种有效的测试技术和该系统尚待改进的地方。
最后,本文对系统的完成情况进行了回顾和总结,并对其今后的发展进行了展望。

Abstract
With the rapid development of the world information technology, distance education and traditional education are no longer two worlds with clear boundary, but two worlds moving towards to mutual amalgamation. “Everything has its advantages and disadvantages”, distance education and traditional education both have their respective advantages, and people find that it achieves its best effect bining these two together.
With regard to long-distance education, it must rely on traditional education to insure its natural operation. 80 percent of our national universities have built up CWISs (Campus-Wide Information Systems), and this CWIS has gradually exerted its huge effect. Some of the applications of distance education have e popular on the traditional campus, and its shock to the intrinsic teaching mode has been obvious day by day.
The project we empoldered this time is called Online Real-time Test System. It is one of the distance education’s applications on traditional education. It breaks the intrinsic teaching mode by using the work resources to build up a new test platform. And it also simplifies the plicated operation, enables the students to take different tests or exams more conveniently regardless of the limit of space and time.
This article, firstly, summarizes the main frame of the Online Real-time Test System,
