基于.NET的考试系统中考务功能模块的设计与实现
摘要
现代社会高节奏、高要求的工作环境决定了现在人们在工作之余还需要进行其他方面的学习,因此兴起了很多有针对性的技能培训。在参加这类培训时,其学习时间安排较灵活,而培训机构就需要对学员学习进度进行频繁的修改,这样可能导致学员情况不能及时正确地反映到考务人员从而引起很多不必要的麻烦。本考试系统就是为了培训机构的这种需求而专门设计的,一方面具有普通的网上考试功能,另一方面还具有考务功能。网上考试系统根据平时培训机构学员的学习情况,可自由的调节学员的学习进度,而在需要对学员进行学习评估时就可以通过学员的学习进度来自由的组卷。通过对一个小规模计算机培训机构实际应用的研究建立了一个适合于培训机构的考试系统,可以极大的简化教育培训所需要的场地与所需费用,也方便更多的人接受到更高层次的教育及时的检查取得的成果,使教育资源能够得到充分的应用。
本论文建立在小规模培训中心考试需求之上,围绕考务系统中的技术难点如何动态生成相应难度系数试卷问题进行了介绍和研究。湖北小规模培训中心的学员人数一般在二千以内,数据库方面采用了SQL Server 2000。考虑到系统的可移植性,系统采用了先进的.NET框架下的ASP.NET及ADO.NET技术。系统采用了缓存技术和多线程技术以提高系统的运行速度。系统充分利用IIS和SOL2000的安全策略,通过角色和权限管理,MD5加密等方法提高了系统的安全性。
本论文的突出之处在于:可为每位登录学员创建生成难度不同、内容不同的试卷。当为题库中每道题目设置难度等级标号,引入分层随机抽样技术为实现不同难度选择后,在相对应的难度题目中随机抽取,即可生成对应难度,不同内容的多份试卷。
The modern society high rhythm and the high request's working conditions decide the present people needed to carry on other aspects beside the work time, therefore many target-oriented skill training has been started.When participating this kind trains,the study progress have to adjust the work time.The training organization have to study the progress to the student and to make the frequent revision to carry on the study situation inspection,then reflected again for the testing personnel,like this possibly causes the student situation not to be able to reflect the testing correctly promptly.This test system is designed for this kind organization requirement:On the one hand has the ordinary on-line test function,on the other hand also has the testing function.This test system based on the study situation of the organization student, adjustment student's study progress to their work time,and carry on the study appraisal to the student may come the free group volume through student's study progress.Through the research which is based on a minicomputer training organization practical application's established the training organization test system,may enormous simplified education training need the location with needs the expense.
Present paper's research is the establishment in the small training center test demand,Carded on the introduction and the research regarding has the testing system's in technical difficulty how dynamic production corresponding difficulty coefficient examination paper question.A small training center student population in Hubeigenerally in 2000,therefore the database aspect has used SQL Server 2000. Considered the good portability of software,we have used the advanced.NET frame ASP.NET and the ADO.NET technology.The system uses the buffer technology and the multi-thread technology,reduced the response delay.The system usesⅡS and the SQL2000 security policy fully,through the role and the authority management, message-digest algorithm 5 methods enhanced system's security.
This research's place of innovation lies in:founds the production difficulty for the debarkation each debarkation student to be different,content different examination paper.Introduction lamination Stratified Probability Sampling,as database in each topic establishment difficulty marking.After realizing the different difficulty choice, in corresponds in difficulty topic draw an item at random,production correspondence difficulty,different content many examination papers.
