Design Of A General Curriculum Exam Question System And Research On ITS Key Techniques

With the increasing enrollment of colleges and universities, and the diversity of teaching subjects, as a result, a complete management system for producing examination question should be established urgently. The new system should be generalduty that it can realize the empty of formulas, customization of the curriculum, the types of questions, difficulty and test paper. According to teachers’requirements, it can automatically form the exam papers by randomly selecting questions.Many item bank systems have been developed. While most of them are used Client/Server (C/S) mode, rather than Browser/Server (B/S) mode. The system which is based on C/S mode is inconvenient on data’s updating and system’s maintenance. However, the existing question banks which are using B/S mode have a lot of problems, such as single question types, emphasis on text. These systems also donot support the question with formula and picture. At the same time, the generating papers are online paper, which cannot be edited. Based on the above reasons, it is difficult for us to use them in the teaching examination. This thesis introduces the design and implementation of a new question bank which is based on ASP.NET, using B/S mode. The system solves many problems, such as the user’s permissions, the item bank’s entering by word editor, generating word-test paper and so on. To meet the general requirement, this thesis focuses on two key problems. For the webpage doesnot support the question with formula and picture. A pressing matter of the moment is to solve the entry of these questions. The other question is how to generate a word-test paper automatically. This thesis proposes two methods to solve the above problems. One is storing the questions in the server with the form of a word file. After that, the system can submit the store path to the database. When we need the questions stored in the server to generate a word-test paper, we can search its store path in the database with its ID. Using word combination technology, it is easy for us to combine with the word file into a word test. Through taking the questions into a binary form, the question can enter into the question bank. This is the other method. The system will read the binary data for each test file into a temporary word files. As with the first method, the system can use the word combination technology to combine with the word file into a word test.In order to make the system more perfect, this thesis also designs and realizes the overall system. We take many measures to make the system much better, such as using parameterized queries to prevent SQL injection attacks, using Ajax technology to ensure a good user experience and so on. The analysis of the item bank is introduced in this thesis at the beginning. Then the basic system architecture, the database model and the general function are designed. Finally we focus on the entry of the questions and the method of generating a word-test paper.
