网络工程师在线学习与考试系统需求分析
摘要
随着Internet 的迅速发展和广泛普及，网络化教育代表了教育改革的一个发展方向，已经成为现代教育的一个特征，并对教育的发展形成新的推动力，远程教育成为现代教育技术发展的重要方向之一，考试测试作为远程教育的一个子系统也成为一个重要的研究领域。
Internet 技术的发展使得考试的技术手段和载体发生了革命性的变化，Internet 的开放性，分布性的特点和基于Internet 的巨大的计算能力使得考试突破了时间和空间限制，与传统考试模式相比，在线考试具有无可比拟的优越性，可以大幅度增加考试成绩的客观性和公正性。
传统的考试方式一般要经过人工出卷、考生考试、人工阅卷等过程，对于一些课程来说，随着考生数量的增加，教师出卷阅卷的工作量将会越来越大，并且其工作量容易出错。在线考试系统计算机软、硬件和网络资源实现无纸考试以避免传统手工考试的不足，实现考试的客观性、公证性、自动化组卷、阅卷可以减轻教师的工作强度，不用印试卷，不用监考，不用讲评试卷。简化了传统考试的过程。
本文以Internet 为平台，研究了基于Web 的网络工程师在线学习与考试系统的设计与开发，包括系统需求分析功能设计以及数据库设计，重点阐述了用户注册模块、用户登录模块、在线考试模块、题库管理模块、试卷评分模块、用户学习模块、错题本模块的设计。
关键词：在线学习与考试、Internet 、设计
Abstract
With the rapid development of Internet and popularization, network education
represents a development direction of education reform, has become a feature of modern education, and form a new impetus to the development of education, distance education becomes one of the important direction of modern education technology, the examination test as a subsystem of the remote education has also become an important area of research.
The development of Internet technique makes the examination technology means and carrier of revolutionary changes have taken place, the openness of the Internet, the characteristics of distribution and based on the huge computing power of the Internet makes the exam broke through the time and space constraints, compared with the traditional exam mode, online examination has incomparable superiority, can greatly increase the objectivity and impartiality of the examination results.
Traditional way of examination generally go through artificial volume, the examinee exam, marking process, such as for some courses, the increase in the number of students, teachers out of the volume marking workload will be bigger and bigger, and the workload is error-prone. Online examination system of computer software and hardware and network resources to realize the paperless test to avoid the shortage of the traditional manual test, and realize the objectivity of the examination, the former, automatic group volume, marking can reduce the work intensity of the teacher, don't have to print paper, need not invigilation, without evaluation test paper. Simplify the process of traditional examination.
Based on the Internet as a platform, this paper studies the network engineer online learning and examination system based on Web design and development, including system requirements analysis function design and database design, expounds the user registration module, user login module, on-line examination module, question bank management module, test paper grading module, user learning module, the wrong topic this module design.
Keywords: online learning, the Internet, design with the test.
