题目: 自动组卷系统开发
Development Of Test paper Auto-production System
摘要
本文首先分析了自动组卷系统在具体的教学活动过程中的实际需求,然后以C语言程序设计的教学为背景,设计与实现了一个实际通用的自动组卷系统,对其中的数据库结构设计以及各个主要模块的实现进行了详细的介绍。
本系统可以从试题库中自动的查找和组织出一些不同题型、不同难度、不同章节范围内的试题来组成一份合理的试卷。它采用的是利用试卷的一组特征值,记录用户提供的试卷题目类型、章节分布、难易程度等条件,采用随机算法,借助于系统中的一系列数据文件,使具体课程的相关数据动态地抽象成逻辑数据,用以解决通用问题,线性的规划出一份约束满足的、合理的试卷。
本系统的开发工具是powerbuilder ,ess 2003。系统分为题库编辑、自动组卷、试卷存储、试卷打印等功能。
关键词:自动组卷题库管理数据库
Abstract
This paper analyses the actual demand of auto-production for test paper system in the course of concrete teaching activity at first. Then taking teaching of C language program design as the background,it designs and realizes a Test paper auto-production system.
First, it Explains the design for the database structure, then introduces the detailed one to the realization of each main module among them. It can automatically find anize a certain number of test questions in various types with different degrees of difficulty in certain scope in the database to form a reasonable test paper. What it adopt is to make use of to try a characteristic value of winding, recording the customer to provide of try a topic type, chapter to distribute, difficult easy degree etc. condition, adoption random calculate way, ask for help from a series of data document within system, make the related data dynamic state ground of the concrete course abstract the logic data, resolve the in general use problem in order to, line program a stipulation of to satisfy of, try book reasonablely.
The development tool of this system is powerbuilder , the database of is Access system is divided into database edit, test paper auto-production, test paper saving, test paper printing etc. function.
Keywords: Test Paper Auto-production ; Database Management of Test Questions ; Database ; Powerbuilder
