一种基于题库自适应考试系统的设计与实现

One Kind Based on Question Bank Self-adapted Test System Design and Realization

目前考试系统设计,从组卷方面来看,主要解决如下问题:①试题的难度系数是预设、固定的,当发生与实际偏差时不容易调整。②难度系数不能随着考试群体接受情况的变化而改变,考试结果必然超出预期。③同题型同知识点的试题重复出现情况较严重,这违背了组卷原则。针对上述问题,论文提出进行基于题库自适应考试系统的设计和实现方法。

At present takes a test the system design, looked from the group volume aspect, main solution following question： 1 st, the test question difficulty coefficient is supposes in advance, fixedly, when occurs with the actual deviation is not easy to adjust. 2nd, the difficulty coefficient cannot accept the change of situation along with the test community but to change, the test result surpasses inevita- bly anticipated. 3rd, the same topic same knowledge test question repetition has the situation to be serious, this has violated the group volume principle. In view of the above question, the paper proposed carries on based on the question bank auto-adapted test system design and the realization method.
