水产养殖知识考试系统随机组卷算法的实现

Realization of Random Test Paper Algorithm for the Aquaculture Knowledge Test System

水产养殖知识考试系统基于浏览器/服务器结构,采用基于随机算法抽题,试题库中的试题以单个试题的形式存放且不形成成套试卷,按题型、难度、区分度、题分、知识点等分别进行分类管理。考生按考题要求完成通用浏览器向服务器传送,该系统使用类和对象对考生上传的文件进行实例化,从中读取相应属性进行判分,再把最终分数写入考生成绩数据库中。

Based on the structure of browser and servers,the aquaculture knowledge test system adopted the randomized algorithm extracting questions,the questions in the database were storied as individual question without being organized into a complete set of test paper,and then managed by categorizing them according to their types,difficulty,distinguish,scores and tested knowledge.By sending the examinees＇ answers from the browser to the server,the system instantiated the uploaded file of the examinees based on class and object,gave a mark to the read information,and at last input the final scores into the database.
