From the view of knowledge and knowledge representation, the thesis discusses and analyses old computer testing systems . through the discussion and analysis we can find out ultimate faults in those systems . since they all use process knowledge representation to realize their functions, they are closed testing systems 本文从知识及知识表示方法角度出发,对以往的计算机考试系统进行了全面的分析和讨论,从中找到这些考试系统的根本缺点,在于这些考试系统是封闭的考试系统,即这些考试系统均使用过程表示法来实现。
On database and conect with the current condition on the examination theory, wuhan chemical college computer test system aim at the characteristic of the basic computer, use this kind of manner to realize test without paper, in wuhan chemical college we design the the whict computer aided test, use the diffent mode in the different condition . . the clasical test is always used in the final test in term, give a certain point to students according with the present teaching system . the comupter adaptived test is used in trainingto find students'shortage . the whict computer test can accord to the teaching evaluation system to analyse students'capacity and papers'quality for improving our teaching molar 以考试理论为基础并结合实际应用,武汉化工学院考试系统针对计算机基础课特点,采用计算机辅亡玉八硕士学住论文wniaster’stifesis助考试方式,实现学科无纸化考试,设计在不同情况下采用不同模式,传统考试应用于学科的考试测验,可以给学生打分,符合现行教学制度,自适应考试用于学生练习,找到自己的不足,考试系统还能够按照教学评估体系的要求对学生能力和试卷质量进行分析,从而达到对教学质量的提局。
This paper introduced a type of computer testing system of three-phase asynchronous motor and its general designing idea . designing computer automatic testing system's hardware frame . at the same time, developing the software of computer automatic testing system 本文应用vb6.0和vc6.0开发了智能化异步电机自动测试系统的操作软件与平台,在此基础上,通过com技术,结合access数据库和excel电子表格等应用软件开发本系统的数据管理、查询、报表图形曲线打印系统。
