针对传统的单一评价模式不能全面反映高校体育教师综合素质的现状，基于主成分分析法，通过降维将多变量的高维空间化简成低维的综合指标问题。以主成分的定义和性质为基础，按照评价过程构建了数学模型，并对具体实例进行评价。评价过程包括计算特征值与方差贡献率、计算因子载荷矩阵并构造因子分析表达式、构造综合评价表达式；实例将7名教师的多指标评价转化为4个主因子评价并得到结果。丰富和发展了教育评价理论，对促进高校体育教学的持续健康发展具有重要作用。

In view of the present situation of evaluation of the traditional single model cannot fully reflect the comprehensive quality of PE teachers in colleges .This paper based on the principal component analysis method and simplifies the multi variable of the high dimension space into comprehensive index of low dimension by di -mension reduction .As the basis of the definition and properties of principal component , construct the mathemati-cal model and evaluate the specific examples in accordance with the evaluation process .The process of evaluation includes calculating the characteristic value and the variance contribution rate , calculating factor loading matrix and constructing the expression of factor analysis , constructing the expression of comprehensive evaluation;The example change the evaluation of 7 teachers into 4 evaluation of principal factor and then get a result .The results of this study enrich and develop the theory of educational evaluation and play an important role in promoting the sustained and healthy development of PE teaching in colleges .
