加权综合教学评估模型的失效与改进

On invalidity and improvement of weighted aggregative teaching assessment model

在多指标加权综合教学评估问题中,指标的不同权重实质上指示出这些指标处于系统的不同层次,因此不能“同层并论”.忽视不同权重指标处于不同层次这一实质性信息,会导致评估失效.改进的办法是采用基于联系数的系统态势排序进行综合评估,以充分利用不同权重指标的层次信息,得出符合实际的综合评估结论.

Concerning the problem of multi-target weighted aggregative teaching assessment, the difference of targets in weight virtually indicates that these targets are in different hierarchy of the system, and therefore cannot be ＂talked about in the same hierarchy＂. Ignorance of this virtual information will result in the validity of the assessment. The way of improvement lies in adopting a system posture ordering based on connection number to carry out aggregative assessment so as to make full use of hierarchical information of different weighted targets to give an aggregative assessment conclusion which satisfies reality.
