摘　　要：目前的计算机考试系统大多数是采用标准答案文档与考生文档直接比对的方式来实现操作题的自动阅卷,评分效率不高,成绩容易出现误差。针对这一现象,以Word 2003操作题为例,提出了改进的思路及具体的实现方法,即基于VBA技术和Word对象模型,采用将标准答案存储到数据库中的方式,利用设置好的标准答案数据库,启动自动评分系统对操作题进行自动评分。实验结果表明,采用此方法设计的评分系统,平均30s左右就可以实现一个文档的自动评分,显著提高了操作题的评分效率。At present, the standard answer document is adopted to directly compare with the candidate documents to realize the operational problems automatic scoring in most of the computer examination systems, in which the scoring efficien- cy is not high and scoring results prone to error. In view of this phenomenon, taking Word 2003 operating problem as an ex- ample, an idea for improvement and a specific realization method for scoring are put forward. The method is based on visual basic for application （VBA） technology and Word object model. In this way, the standard answers are stored in the database, and the automatic scoring system conducts the automatic scoring of operation problems by means of the standard answer data- base. The experimental results show that the automatic scoring system designed in this way can fulfil a candidaters document scoring in about 30 s automatically. It significantly improved the scoring efficiency of operation questions.
