| 摘 要： | 提出参数赋值以测试为辅、以人工为主两种方法相结合的思路,并探讨了不同赋值方法效果的差异。结果表明,按影响难度的因素进行难度赋值的效果好于综合地直估难度进行赋值的效果;客观题的赋值效果不如主观题的赋值效果。对区分度的赋值也进行了初步的试探,结果表明,按影响难度的因素进行区分度赋值的效果好于其他方法。

| Abstract: | This article proposes a parameter evaluating idea of combining two approaches, i. e. artificially evaluation-centered approach and testing-assisted approach, and discusses differences of effects between various evaluation methods. The result indicates that difficulty evaluation in the way of employing factors influencing difficulty is better than estimating directly; evaluation effect of the objective items is inferior to that of subjective items. Discrimination evaluation is also carried on the preliminary probe. The result indicates that discrimination evaluation according factors influencing difficulty is better than the other approaches. |
