多元统计分析在外语教学质量评价中的应用

Application of multivariate statistical analysis in foreign language teaching evaluation

为了更加客观地对大学外语课堂教学进行评价,使用多元统计分析中的主成分分析和因子分析法建立了课堂教学质量评价模型,构建了以每个主因子的方差贡献率作为权重的综合评价函数,对教师课堂教学质量进行综合评价排名。以某高校8位外语教师课堂教学质量评价数据进行实例验证,并与其原始排名进行对比,结果显示使用多元统计分析法评价外语课堂教学质量更客观、更合理。

To evaluate collage foreign language classroom teaching objectively,the evaluation model of classroom teaching quality was established by using principal component analysis and factor analysis in multivariate statistical analysis. The compre?hensive evaluation function which takes variance contribution rate of each principal factor as weight was constructed to evaluate and rank for classroom teaching quality comprehensively. The evaluation data of 8 foreign language teachers′ teaching quality are proceeded instance verification. The evaluation data are compared with original ranking. The experimental results show that using multivariate statistical analysis to evaluate the quality of foreign language classroom teaching is more objective and reasonable.
