教育评价的信度,指评价结果稳定可靠的程度。笔者认为教育评价的信度可分为评判者信度和内部一致性信度两类。评判者信度是用表鉴别评判意见集中程度的指标。可以设想,在一般情况下,稳定可靠的评判结果只能在评判者意见一致或比较一致时才可能获得。尚若评判意见非常分散,甚至尖锐对立,那么只能从评判本身去查明原因,或许是评价因素内涵不明确具体,或许是对评价标准理解各异,必须及时采取补救措施进行复评。另外,内部一致性信度是用表鉴别综合评价中各项目是否能一致辨认整体的程度的指标。因为在复杂而多因素的综合评判中,可靠结论的获得仅靠评价者的意见一致是不够的,还要看各项目之间的意见是否比 The reliability of education evaluation refers to the stability and reliability of evaluation results. I believe that the credibility of education evaluation can be divided into two types of reliability of the judge and internal consistency. Judgment reliability is to use the table to identify the concentration of judgments. It is conceivable that, in general, a stable and reliable judgment result can only be obtained when the judge’s opinion is consistent or relatively consistent. If the judgment is still very scattered, or even sharp opposition, then only from the judge itself to find out the reasons, perhaps the evaluation of the content is not specific and specific, perhaps to understand the different evaluation criteria, we must promptly take remedial measures for re-evaluation. In addition, the internal consistency reliability is used to identify the table in the comprehensive evaluation of whether the project can unanimously identify the overall extent of the index. Because in complex and multifactorial comprehensive judgments, it is not enough to obtain reliable conclusions only by the evaluators, but also to see whether the opinions among the various projects are better than
