分段随机抽选算法在工程图学智能试题库系统设计中的应用

Application of Divided Selection at random Algorithm in Intelligent Examination-Questions Bank System Design for Engineering Graphics

工程图学试卷以图形为主,针对其出卷难的问题开发了基于VB的工程图学智能试题库系统;本文重点讨论了工程图学的自动组卷策略和分段随机组卷算法,该算法可根据设定好的难度系数进行自动组卷,成功率高、方便快捷。

The graphics are a major component of the engineering graphics papers, and intelligent examination-questions bank system for engineering graphics based on VB is developed for the difficult problem of the Test Paper Generation. The paper focused on the strategy of test paper generation and the algorithm of divided selection at random of automatic generating test paper. It can automatically generate test paper according to the predetermined coefficient of difficulty. It has a high success rate, fast and convenient characteristics.
