基于层次分析和灰关联分析的虚拟仿真实验过程评价研究

Research on Evaluation of Virtual Simulation Experiment Process Based on Analytic Hierarchy Process and Grey Relational Analysis

针对虚拟仿真实验缺乏过程性评价,无法掌握学生对虚拟仿真实验操作过程的情况以及评价的方式单一等,提出基于层次分析和灰关联分析评价模型。为建立一个面向实验的评价体系,通过工作分解结构方法对实验过程因素进行层级划分,构建虚拟仿真实验过程评价指标体系;对调查得到的指标进行分析,利用层次分析计算指标权重、灰关联分析确定不同过程因素对实验的重要程度;以虚拟仿真实验教学管理平台中选取的实验课程为例进行分析计算。应用该评价模型对虚拟仿真实验过程影响因素的结果进行排序,得出应重点关注实验过程中仿真学习记录产生的影响。

In view of the lack of process evaluation of virtual simulation experiments,the inability to grasp the students’operation process of virtual simulation experiment and the single evaluation way,the evaluation model based on Analytic Hierarchy Process and grey correlation analysis is proposed.In order to establish an experiment-oriented evaluation system,the factors of the experiment process are divided into levels by the method of work breakdown structure,and then the evaluation index system of the virtual simulation experiment process is constructed.The index data obtained from the survey are analysed,each index weight is calculated by chromatography analysis,and the importance of different process factors to the experiment is determined by grey correlation analysis.The experimental course selected from the virtual simulation experiment teaching management platform is taken as an example for calculation and analysis.The evaluation model is applied to rank the results of the influencing factors in the process of experimental virtual simulation,and draw the conclusion that we should focus on the impact of experimental learning records in the experiment process.
