粒矩阵与模糊综合评判融合的课堂教学质量评价研究

Research on the quality evaluation of classroom teaching based on the combination of granular matrix and fuzzy comprehensive evaluation

针对课堂教学质量评价体系中指标权重确定方法存在的不足,以粗糙集理论为基础,提出了一种基于粒关系矩阵与模糊综合评判相融合的课堂教学质量评价方法.首先,基于粒关系矩阵计算课堂教学质量评价体系中评价指标权重向量;然后通过隶属度函数建立模糊评判矩阵;最后将各指标的权重向量与模糊评判矩阵进行合成,计算出各指标的综合评价结果.实例分析表明该方法的可行性与有效性.

In view of the deficiency of the method for determining the weight of indicators in the classroom teaching quality evaluation system,a method of classroom teaching quality evaluation based on the combination of granular relationship matrix and fuzzy comprehensive evaluation is proposed on the basis of rough set theory.Firstly,the weight vector of evaluation index in classroom teaching quality evaluation system is calculated based on the granular relation matrix.Then,the fuzzy evaluation matrix is established by the membership function.Finally,the weight vector of each index is combined with the fuzzy evaluation matrix to calculate the comprehensive evaluation results of each index.An example shows that the method is feasible and effective.
