30、r 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

31、successfully applied to the distance evaluation of basic operating skills of computer science,such as the course of com</p><p>　　Index Terms </p><p>　　Examination system,Auto-grading system,Web-

32、based,DCOM</p><p>　　1. Introduction</p><p>　　In China, the education for basic computer operating skills has been broadly launched. The skills include the operating of Windows, MS Office, Networ

33、king skills, etc., which are the foundation of a combination of different courses, as well as of electronic-government. Now, every undergraduate must pass the course of the Computer skills, while every civil servant must

34、 pass the corresponding Computer Operating Exams. Furthermore, the basic computer education in high schools is in process. Since th</p><p>　　Several Web-based learning and testing systems have been designed,

35、 such as WebCT[1], QUIZIT[2], ASSYST[3], and PILOT[4]. The most widely used question types of the Web-based examination system are objective tests and quizzes which assume simple answers that can be formally checked and

36、easily evaluated online. The typical questions are limited to yes/no questions, multiple -choice/singleanswer questions, multiple-choice/multiple-answer questions, and fill-in questions with a string and numeric an</p

37、><p>　　Our examination system for basic computer operating skills has the following characteristics: (1) The question types include not only objective questions, but also operating questions as Windows, MS Word

38、, MS Excel, Internet skills, etc. (2) The goal of the learning and testing system is to train the practical skills. As a result, operating and testing in the actual environment of the client machine is the best learning

39、method. (3) It is urgent to develop an automatic grading system which can gra</p><p>　　We have developed a novel online examination system based on a Browser/Server framework using state-of-art computer tech

40、nologies, which carries out the examinations for basic computer operating skills including objective tests, Visual Basic programming, Microsoft Windows operating , Word, Excel and PowerPoint editing, Internet and Email

41、skills, etc. It has also implemented automatic grading online.</p><p>　　2. System Architecture</p><p>　　Our web-based examination system is a distributed collaborative system which is based on D

42、COM technology. It has four major components : the examination preparation system, the examination system, the examination monitor system and the auto-grading system.</p><p>　　The preparation system is used

43、to manage question storage, assign test ID and schedule the test. The question database is composed of the questions, a set of possible answers, the question types and other metadata, which are indexed by several factors

44、, such as topics, keywords, complexity and difficulty, etc. The database is open to teachers, allowing them to add questions and answers by template.</p><p>　　The examination System is a web-based testing in

45、terface for students , called WOES , which include the following key features: client side control, time control, security control and auto-installation. Benefiting from DCOM technology, the system can install and update

46、 itself conveniently, better than the C/S framework. Because the system is established on the Web, the systematic security faces a severe challenge. We guarantee the security by cryptography, real-time monitoring system

47、and data tra</p><p>　　The real-time monitoring system requires students not to leave the computer during the test by face tracking technology. The data transmission encryption system transmits the examinatio

48、n question and result in secret form through the network to the server. The examination monitor system is also the manager of the examination system, by which we can monitor the test processing, carry out test ID statist

49、ic and collect the answers, etc.</p><p>　　The auto-grading system is designed by the fuzzy matching algorithm and the macro programming technology, which is seasoned with variable question types.</p>

50、<p>　　3. Web-Based Online Examination System</p><p>　　3.1 The aim of the examination system</p><p>　　As a universal examination system for the education of basic computer operation, it must

51、 meet the following requirements:[6]</p><p>　　1. A reasonable question storage, which must conform to the general outline of the exam.</p><p>　　2. A practical interface. There are two types of e

52、xam interfaces. One is the simulation, the other is the actual environment. The second scheme will give the student more flexibility because of the practical nature of computer skills.</p><p>　　3. A range of

53、 question types , such as objective questions, operating questions, design questions, information retrieval, group testing, etc.</p><p>　　4. A safety and reliable examination system.</p><p>　　3.

54、2 The components of WOES</p><p>　　The Web based Online Examination System (WOES) is a multi-layer system which is composed of the Web Server, Database Server, WOES middleware Server, WOES client module and B

55、rowser, 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.</p><p>　　The kernel of WOES is the WOES

56、 middleware Server 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 d

57、ifferent 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 providing communication inte

58、rfaces between WOES clients an</p><p>　　Benefiting from DCOM, the WOES clients can be downloaded or updated automatically from WOES middleware Server on the Internet. They can also move from one client to th

59、e other and communicate with the WOES Server. The system acts like an Agent society, which is a centralized Agent system controlled by only the WOES Server.</p><p>　　3.3 The key technologies of WOES</p>

60、;<p>　　1. A user-friendly interface</p><p>　　We use browser as our user’s interface. The Browser interface has a uniform and consistent user interface. Almost everyone is able to use it skillfully. Th

61、erefore it can eliminate the differences of various exam systems and guarantee a fair test.</p><p>　　2. Simplified system maintenance</p><p>　　Since the system is based on Browser/Server archite

62、cture, the teacher can update the system or the question database or examine the student’s database only in Server. It is not necessary to update the client system as the Client/Server must do.</p><p>　　3. C

63、entral examination management</p><p>　　Profiting 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

64、and monitoring the students’ conditions on the teacher’s screen.</p><p>　　4. Security</p><p>　　The most severe difficulty which the B/S based system faces is security, because in principle the w

65、eb-based examination system can be accessed on the Internet or WAN in a city.</p><p>　　?All the questions, materials and answers are transmitted in bits stream format after encoding, not in file format. It c

66、an ensure not only security in the transmission process, but also protect from invasion.</p><p>　　When one student starts his test, the system will distribute him a password produced according to his client’

67、s hardware and operation system environment. It can prevent cribbers to login from other clients imitating this student.</p><p>　　?The newest method to prevent the distant student from leaving the client or

68、is making use of face detection and recognition technology. Before the start of the exam, the student is asked to sit in front of the computer camera which can monitor the whole scene. Then the system will automatically

69、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.</p><p>　　4. Auto-Grading System</p>

70、<p>　　The auto-grading system can automatically grade theanswers, which are collected from the examination system . It helps teachers to achieve the score with ease.</p><p>　　There are two types of th

71、e 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

72、difficult to grade operating questions by simple matching technologies. A possible solution could be: (1) Reading the answer file directly and comparing it to the key file. But this is not practical because the format of

73、 Microsoft Office files is complica</p><p>　　We propose a universalized grading system which is carried out on the basis of a database of key knowledge.</p><p>　　First, we extract all possible k

74、nowledge 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

75、 key library. So, the last process of autograding 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 syste

76、m.</p><p>　　5. Conclusion</p><p>　　We have developed an overall solution to the examination system for practical computer skills . It provides a userfriendly platform of various questions for th

77、e basic computer education in Universities, civil servant training and nationwide examination for high school graduates in Zhejiang Province, Hundreds of thousands of students and teachers have used this system and agree

78、 that it has effectively raised the learning and testing efficiency.</p><p>　　6. References</p><p>　　[1] WebCT,”Web Courses Tolls”,http://www.webCT.com.</p><p>　　[2] Tinoco, L., Fox
