Design on Online Examination System for College English

Abstract

English is a foreign language curriculum, strengthen the inspection information construction is the key to improve the students' English comprehensive ability. In order to quickly and easily test students' English learning situation for a period of time, realize English inspection information, designed on the online examination of English, lay the foundation for software development. The mainly carries on development technology introduction, summary design, design of process and database table design. Among them, summary design designs function of each module in detail; design of process designs complete process of procedure in detail; database table design designs associated table structure in database in detail. The research contents of this thesis have important significance to improve the quality of English learning and the students' English level etc. Introduction English is a basic language courses, English has two contents, one is the English class for non-English major the other one is to lay a foundation for nature, to achieve the College English Syllabus four level requirements for the purpose of opening a basic English course [1]. The organization of traditional examination way generally have to go through the steps: manual, paper design, printing test paper, the examination room arrangement, examinee examination, examination paper collection, artificial volume change, performance reporting, results announced and exam evaluation etc. This will undoubtedly cause a great waste of manpower, material and financial resources and time, and work intensity, low efficiency, the also feel bound and passive [2]. Errors may also be in the marking process, affect the test results. With the reform unceasingly thorough, the traditional examination way more and more can not meet the actual needs, and the online examination based on campus network can break through the traditional way of examination to make examinations more flexible, but also can save a lot of time, manpower, material and financial resources, improve test efficiency and standard level [3,4]. In order to improve the English teaching quality and students' English level, realize English inspection information, designed on the online examination of English, lay the foundation for software development. Development Technology Introduction Based on the design of online examination system, this paper chooses the database for SQL server. Database design, interface design use the development language for ASP. NET. First of all, ASP. NET it is mainly used to create dynamic WEB applications. The compatibility is strong, it can not only be compatible with C, C#, can be compatible with many browsers, it ensures that the online examination can run in many browsers, do not have to worry about compatibility issues, it also enhances the universality of the online examination applications. ASP.NET sometimes also can be used as a programming language, associated with the ACTIVEX component, ASP command, HTML Webpage technologies to create an application based on WEB [5]. Secondly, ASP.NET is some code encapsulated in the control, through the JIT technology will translate the intermediate language into code, can be faster to invoke the WEB page, it also enhances the flexibility of the application of online examination system.

The authors Published by Atlantis Press 305 Summary Design Summary design is the next step to be analyzed, the main task is to get the DFD needs analysis converting software architecture [6]. Summary design usually use configuration diagram to depict a functional configuration of the software, the purpose is to ensure that based on the realization of logic model, as far as possible to improve the target simplicity, variability, consistency, integrity, reliability, economy, efficiency and safety of operation. A structure diagram of the shown in Fig. 1. In Fig. 1, the name of the top level with a of college English online examination system means. The second layer is divided into students, and three kinds of users, each represents a module. The third layer with specific functions of each module, where students user functions include online answer, extract papers, submit papers, query results; user functions include mark papers, bank management, performance management, papers analysis; user management functions, including teachers management, management, maintenance, backup. In each module, the definition of each specific function has its specific meaning. For example, in students module, online answer says after a successful login according to random distribution questions in the question database to answer, in a specified time, complete answer, submit questions; in module, bank management says teachers can add, modify and delete test information, randomly distribute questions of question bank to the online test students; in module, backup says administrator makes a backup of data of system-generated student achievement, to prevent data loss. Design of System Process The process can be depicted by flow chart of the system. The flow chart of the is the traditional tools of drawing physical model, expressing the flow of components of the system, rather than the control process of information processing [7]. The is divided into teachers, administrators of three users, the user to as an example to illustrate the process of the design of process, as shown in Fig. 2. System process design description: After the user starts the application, enter the login screen, when a user logs on to the system, the prompts the user whether the account; if there is, the user is prompted to enter a user name and password; if not, the user is prompted to register account, after successful registration, re entering the login interface, input the registered user name and password. If the input is correct, enter the main interface, the user can select function, performs the required operation; otherwise, enter again, until you enter the correct user name and password, may Online examination of English Students Administrator Teachers O nline answ er Etract ppers Subm it ppers Q ery rsults Prform ance B nk m aagem nt M rk ppers Techers m aagem nt Stdents m aagem nt Sstem m ainnance Sstem bckup Ppers anlysis Fig. 1.
