【摘要】：考试是检验学生接受知识程度的重要途径,也是检测教师教学效果的重要环节。信息化时代的今天,我们周围的一切事物都在飞速发展,考试模式也不例外。传统的考试方式耗费大量时间、人力,且受到重重客观环境的限制,在计算机相关技术发达的今天,基于网络端的在线考试系统逐渐出现在人们眼前,发展速度迅猛,有逐步取代传统考试的趋势。本课题根据用户的需求,利用微软的.NET框架研究并实现了一套网上考试管理平台,其主要功能有:用户登录、系统管理、题库管理、智能组卷。本文对该平台的总体结构、数据库设计、各个模块及主要算法的设计和实现过程做了详细描述,并给出了相关实验结果。在网上考试系统中,人们最关注的问题在于考试系统自动组卷的“质量”,这也是评价一个考试平台算法是否优良的重要准则。在本文中,针对传统的组卷算法即遗传算法,在算法实现过程中,组卷成功率和效率都不能满足用户需求的前提下,对原有的遗传算法进行了改进,提高了算法效率以及组卷成功率。在设计智能组卷功能时,设置了三种可供用户选择的组卷方案,分别是知识点所占百分比、知识点在题型中的分布、人工选题,前两种方案为智能自动组卷,第三种方法作为补充。本课题设计并实现的网上考试管理平台,可针对不同课程、知识点、题型的试题进行管理,并根据出题人不同的组卷要求进行自动组卷并可以在考生完成后进行自动阅卷,评分。此外,在考生完成考试后,教师以及管理员还可以通过学生的成绩、错题分布情况对考试情况进行整体分析,有利于对教学工作的合理安排。经过测试,本考试平台各项功能运行良好。
[Abstract]:Examination is an important way to test students' acceptance of knowledge, and also an important link to test the teaching effect of teachers. In the information age, everything around us is developing at full speed, and the examination mode is no exception. The traditional examination method consumes a lot of time, manpower, and is restricted by a lot of objective environment. Nowadays, with the development of computer related technology, the online examination system based on network has gradually appeared in front of people's eyes, and the speed of development is swift and violent. There is a tendency to gradually replace traditional examinations. According to the needs of users, this paper studies and implements a set of online examination management platform using the .NET Framework of Microsoft. The main functions of this platform are: user login, system management, item bank management, intelligent test paper generation. In this paper, the overall structure of the platform, the database design, the design and implementation of each module and main algorithms are described in detail, and the experimental results are given. In the online examination system, people pay most attention to the "quality" of automatic test paper generation in the examination system, which is also an important criterion to evaluate whether an algorithm of an examination platform is good or not. In this paper, in view of the traditional test paper generation algorithm, that is, genetic algorithm, the original genetic algorithm is improved under the premise that the success rate and efficiency of the test paper generation can not meet the needs of the users in the implementation of the algorithm. The efficiency of the algorithm and the success rate of generating test papers are improved. In the design of intelligent generating test paper function, three kinds of test paper generating schemes are set up, which are the percentage of knowledge points, the distribution of knowledge points in question type, and the artificial selection. The first two schemes are intelligent automatic test paper generation. The third method is complementary. The online examination management platform designed and implemented in this subject can be managed for different courses, knowledge points and test questions, and can be automatically assembled according to the different requirements of the examiners and can be read automatically after the candidates have finished. Score. In addition, after the examinee completes the examination, the teacher and the administrator can also carry on the overall analysis to the examination situation through the student's achievement, the wrong question distribution situation, is advantageous to the reasonable arrangement to the teaching work. After testing, this examination platform each function runs well.
