基于因子分析的改进高校综合评教模型

A Comprehensive Teaching Evaluation Model Based on Factor Analysis in Universities

摘要: 因子分析是指研究从变量群中提取共性因子的统计技术。本文通过对东华大学的评教数据3174个样本，9个评教指标进行因子分析，对现有的评教模型加以改进，将9个指标降为3个，建立综合评教数学模型B = 0.71B₁ + 0.11B₂ + 0.04B₃，使最终的评教结果更趋于科学性和合理性。实证结果表明经过综合评教数学模型得出的综合评教分值更具代表性。

Abstract: Factor analysis is a statistical technique for extracting common factors from a variable group. In this paper, through the factor analysis of the teaching data of Donghua University, 3174 samples and 9 evaluation indicators, the existing evaluation model is improved, and 9 indexes are reduced to 3, and a comprehensive teaching model of teaching evaluation, B = 0.71B₁ + 0.11B₂ + 0.04B₃, is established which will make the final evaluation result more scientific and reasonable. The em-pirical results show that the score of comprehensive evaluation by comprehensive teaching eval-uation model is more representative.
