340;抽出一组符合考试方要求的试卷.由于组卷系统的组卷过程还与试题库中试题的属性指标有关,所以本文还应用了模糊数学中的模糊综合评价理论,对试题库中试题的难度值等具有模糊性的属性进行了研究,使题库的难度系数不仅取决于专家教师的主观意见,还与学生的实际状况和教学的客观情况相联系.同时,还给出了有效的相关系数法试卷质量分析模型.文章先介绍了试卷质量的传统分析方法,然后引入了相关系数的定义,从统计学角度分析相关系数所代表的含义及性质,并将相关系数灵活应用于考试质量分析,分别用相关系数计算试题的区分度,试卷的信度及效度,并对学生群体能力进行分析以指导教学过程.文章还研究了学生考试成绩的统计规律,采用X2检验法实现了成绩的正态性检验.
最后利用现代计算机技术,数据库技术和网络技术,编程实现了一个基于Inter的考试,考务及评分系统,并对其实现的功能进行了分析.
该网络考试系统也存在一些值得改进之处.首先是在网络安全性方面,如果在考试数据传输过程中加入加密和解密功能以及数据较验功能,就可以保证数据的可靠性和完整性.对考试后考生上交的答卷文件,可以考虑加入数字签名等技术,以保证答卷的不可否认性.
关 键 词:模糊综合评价,自动组卷,遗传算法,网络考试
