在线考试系统的设计与实现毕业论文-在线考试系统毕业论文
摘要随着计算机网络技术和网络教育的不断发展，传统的基于纸笔的考试形式已不能适应现在的发展需要，计算机在线考试正在逐步取代传统考试。
计算机在线考试利用网络实现在线考试、评分等环节，实现教考分离，在一定程度上减少了影响考试的人为主观因素，同时减少了教师的工作量。
在线考试系统的设计就是基于上述目的开发设计的。
本系统采用了模块化的设计思想进行开发，根据学校考试工作的需求分析，并采用用户权限管理的设计思想对系统功能模块进行划分，实现了考生的基本信息管理；试题库更新操作；试卷的自动生成；自动评卷；考生网上考试和查询以往考试成绩等功能。
本文从系统的设想到实现过程作了详细的说明，对完成特定功能模块的工作原理详细作了解说。
系统使用ASP动态网页技术，以VBScript和JavaScript脚本语言和HTML超文本标记语言结合为编写工具，结合SQL server 2000数据库技术开发。
ASP其实是一套微软开发的服务器端脚本环境，它内含于IIS中。
通过ASP我们可以结合HTML 网页、JavaScript、ASP指令和ActiveX控件建立动态、交互且高效的web服务器应用程序。
有了ASP就不必担心客户浏览器是否能运行我们所编写的代码，因为所有的代码都将在服务器端运行，包括所有嵌在普通HTML中的脚本程序。

文献译文-新型的基于web的在线考试系统
A NOVEL WEB-BASED ONLINE EXAMINATIONSYSTEM FORCOMPUTER SCIENCE EDUCATIONYuan Zhenming1, Zhang Liang2, Zhan Guohua3AbstractWeb-based Examination System is an effective solution for mass education evaluation. We have developed a novel online examination system based on a Browser/Server framework which carries out the examination and auto-grading for objective questions and operating questions, such as programming, operating Microsoft Windows, editing Microsoft Word, Excel and PowerPoint, etc. It has been successfully applied to the distance evaluation of basic operating skills of computer science, such as the course of computer skills in Universities and the nationwide examination for the high school graduates in Zhejiang Province, China.1. WEB-BASED ONLINE EXAMINATION SYSTEM1.1The aim of the examination systemAs a universal examination system for the education of basic computer operation, it must meet the following requirements:1. A reasonable question storage, which must conform to the general outline of the exam.2. A practical interface. There are two types of exam interfaces. One is the simulation, the other is the actual environment. The second scheme will give the student computer skills.3. A range of question types, such as objective questions, operating questions, design questions, information retrieval, group testing, etc.4. A safety and reliable examination system.1.2 The components of WOESThe Web based Online Examination System (WOES) is a multi-layer system which is composed of the Web Server, Database Server, and WOES middleware Server, WOES client module and Browser, such as Internet Explorer. In this system, we use the Internet Information Server 4.0(IIS) as the Web Server, the Database Server is Microsoft SQL Server 7.0.The kernel of WOES is the WOES middleware Serve and the WOES client module, which is designed according to Microsoft DCOM standards. DCOM is the binary COM object’s extension jointing LAN, WAN and Internet, which can instance and bind objects over different network. It is an advanced network protocol used to cooperate with COM based components of two processes in different locations. The WOES middleware Server is a server-side component The WOES middleware Server is a server-side component providing communication interfaces between WOES clients and the Web Server or Database Server. The WOES client is a client-side component, which is called by the Browser to control the client computer and submit or receive information from the WOES Server. This technology guarantees the flexibility and the potential for extension of the test system. In addition, it allows access to local files, whereas in conventional systems, the IE security prevents such access.1.3 The key technologies of WOES1. A user-friendly interfaceWe use br owser as our user’s interface. The Browser interface has a uniform and consistent user interface. Almost everyone is able to use it skillfully. Therefore it can eliminate the differences of various exam systems and guarantee a fair test.2. Simplified system maintenanceSince the system is based on Browser/Server architecture, the teacher can update the system or the question database o examine the student’s database only in Server. It is not necessary to update the client system as the Client/Server must do.3. Central examination managementProfiting from the central controlled system, the teacher can easily control the examination process, such as the beginning and end of the exam, collecting the answers and monitoring the students’ conditions on the te acher’s screen.4. SecurityThe most severe difficulty which the B/S based system faces is security, because in principle the web-based examination system can be accessed on the Internet or WAN in a city.All the questions, materials and answers are transmitted in bits stream format after encoding, not in file format. It can ensure not only security in the transmission process, but also protect from invasion.When one student starts his test, the system will distribute him a password produced according to his client’s hardware and operation system environment. It can prevent cribbers to login from other clients imitating this student.The newest method to prevent the distant student from leaving the client or is making use of face detection and recognition technology. Before the start of the exam, the student is asked to sit in front of thecomputer camera, which can monitor the whole scene. Then the system will automatically recognize the student’s face and his identification. As soon as the validation is performed, the student must stay in front of the camera until the exam is finished.2. AUTO-GRADING SYSTEMThe auto-grading system can automatically grade the answers, which are collected from the examination system. It helps teachers to achieve the score with ease.There are two types of the grading: objective questions and operating questions. Objective questions, such as choice questions, yes/no questions, and fill-in questions, can be graded effectively by accurate matching or fuzzy matching. But it is difficult to grade operating questions by simple matching technologies.A possible solution could be: Reading the answer file directly and comparing it to the key file. But this is not practical because the format of Microsoft Office files is complicated.Another solution is: (2) grading by using the Office OLE object. This method is convenient and efficient, but it has a big disadvantage: the source code of the grading system is closely related to the concrete question, which results in a large amount of work when the questions are changed.We propose a universalized grading system, which is carried out on the basis of a database of key knowledge.First, we extract all possible knowledge points and store them in a triple form: (key, value, location). Then we produce the question file by labeling the question point directly on it; the system will add the corresponding question key to the standard key library. So, the last process of auto-grading system is to compare the answer file with the standard key library. The auto-grading system also allows the teacher to add his /her own questions to our examination system.3. CONCLUSIONWe have developed an overall solution to the examination system for practical computer skills. It provides a user- friendly platform of various questions for the basic computer education in Universities. Hundreds of thousands of students and teachers have used this system and agree that it has effectively raised the learning and testing efficiency.一种新型的基于web的在线考试系统Yuan Zhenming1, Zhang Liang2, Zhan Guohua3摘要基于web的在线考试系统是大众教育评估的一种有效解决方法。
