网上考试系统设计与实现英文翻译

    With the rapid development of computer technology, school teaching and management of information technology development has made significant progress, which requires a balanced development in all aspects, from both sides of hardware and software to schools into a class of information management, education and teaching platforms. This examination management system design and development is also an important aspect. The system is based on reduce teacher workload, improve efficiency, optimize the flow of students to test and enhance identification of students take the test than the traditional examination to save human and financial resources and time.     System is divided into three modules: user registration module, test module and the system management module. Including system management module is added to the subject, storage and deletion, is the basis of system operation; query sub-module test information for students remote query. Examination module is a client-side student or teacher through their name and student number and password to login into the interface problem by the system in accordance with the structure of teachers in pre-set good papers randomly selected from the item bank for the subject, the formation of paper.     The system has been developed using structured design. System specification describes the development of mind and the examination system background, system development tools, structured development of concrete steps, including an entity - relationship model, data flow diagram, function chart and other necessary graphics instructions. Preface     With rapid technological development, many foreign universities and other sectors of society have opened teaching, through the computer realized Remote Education and Training. Now, the development of computer hardware technology has reached a very high level. However, the teaching of software development is still in its infancy, with the deepening of the technology development requires a better, more comprehensive software system used in teaching to go, which gives the software designer has set higher design requirement.   Teaching includes many aspects such as teaching systems, answering systems and test systems, among others. One very important aspect is the online examination system, it is also the most difficult part to achieve. In China, although the teaching has been vigorously developed, however the current school and the community most of all exams using traditional test methods, in this manner, organize an examination after at least five steps, namely, the problem of artificial, candidates test , man marking, performance evaluation and analysis papers. Obviously, with the increase of type examination and examination requirements continue to increase, there will be increasing the workload of teachers and their work would be a very cumbersome and very error-prone things can be said to have been the traditional test methods can not meet the needs of modern examinations. With the rapid development of computer applications, applications continue to expand, such as teaching and the emergence of virtual universities, etc., and these applications are gradually and families. It urgently requires the use of these technologies to conduct online examinations, to reduce teacher workload and increase efficiency, while also improving the quality of the examination, so that tends to be more notary exam, objective, and even stimulate learning interest. For example, currently many of the world's leading computer companies organized by the vast majority of certification exams in this way.     Online exam is a hot topic at the present stage of development. It is based on the applications on the Internet, the client configuration can be very simple to test without geographical limitations. A complete online examination system allows users to test their e-learning after the learning time has been found wanting, so learning efficiency is greatly improved. Online examination system in the generation of questions, papers submitted, it takes the results and so can be automatically completed. As long as the formation of a mature examination of Test automation can be achieved. As a result, teachers have to do is carefully designed questions, maintaining item bank, rather than organization of the examination, thereby greatly reducing the burden on teachers, indicating that the economy is considerable. To meet the new situation, I did the preliminary design of the system, it can be said to be a preliminary exploration, hope that it will play in the various examinations efficient and convenient function, the teacher from the heavy work freed!     At present, the application software running model, mainly Type II: Client / server mode, Browser / Web model. The main disadvantage of the former is to maintain, upgrade is more complicated, the latter is the rapid development of Internet in recent years, together with a technology with client / server approach is similar to the client is a standard browser, the server is the Web Server, The Web Server and database and application server closely, making this model expanding the scope of application, it has not only used for online queries, there are many departments of business systems, corporate MIS systems have adopted this model, it The main advantage is to facilitate the expansion of applications, upgrade and maintenance easy.     In addition, the test system software will also continuously updated; while the software product itself must go through a continuous improvement process.     Based on these considerations, the use of Browser / Web model to design more appropriate test system, the server side we use Access database system and the ASP components to form the test application service system; the client browser to complete the examination by the whole process, at the same time remote system maintenance and management.   Use and database technology, combined with the current hardware prices generally fall and the broadband network built in a favorable advantages, application of Active Server Page technology, I developed based on B / S mode multi-user online examination system in this process. It uses convenient, easy, efficient (and, it requires a computer configuration is also high, especially in server-side). Although only a paper at this stage to achieve the objective questions in part, but with user registration, multi-user online exam at the same time, dynamic random questioning, time control, automatic grading, test input, modify the test database, user management, subject management, administrators management, and scores of management and other important functions, that is to achieve a true paperless examination, meet the candidates at any time to any authorized examination and prompt access to results, but also greatly reduce the teacher a question, a question and graders and other heavy workload.     Along with social progress and the continuous development of commodity economy, community workers and technical staff level of knowledge and ability to increasingly high demand. Test as a measure of an important means for human capabilities, in modern life further enhance the status of , and deep into every aspect of the community. a variety of academic certification and qualification after another. At the same time, Internet technology makes the examination of technology has revolutionized the means and carrier changes. Internet's openness and the distribution of characteristics and the examination system based on Internet is becoming one of the hot spots. For example, in the United Kingdom, has achieved the qualifying examination of the online English language learning and the level of the whole process of certification.   The rapid development of computer applications, web applications continue to expand, such as distance education and the emergence of virtual universities, etc., making the online examination system based on WEB become a reality, WEB-based online examination system can play the advantages of the network to establish large, efficient, shared question bank and anywhere, anytime examination, lower test costs, reduce human disturbance, reduce teacher burden, saving human, material and financial resources.
