摘　　要：随着中国高等教育的蓬勃发展,如何对学生进行科学公正的评价越来越受到社会的广泛关注。传统的学习成绩评定法已不能满足高校学生全面发展的迫切要求,针对这一现象,基于某学院网络工程专业学生真实成绩,借助统计分析软件SPSS,采用主成分分析法构建学生成绩综合评价指标体系,结果表明第一主成分对学生最终的综合得分影响最大,采用主成分分析法得到的排名与传统的成绩评定法基本一致,但学生在各个主成分上的得分结果可以直观展现学生的优势和劣势学科,能够帮助学生取长补短。With the vigorous development of higher education in China,how to evaluate students scientifically and fairly is getting more and more widespread attention from the society.The traditional academic achievement evaluation method can no longer meet the urgent requirements of the comprehensive development of college students,in response to this phenomenon,based on the real achieve⁃ment of network engineering students in a college,with the help of statistical analysis software SPSS,the principal component analysis method is used to construct a comprehensive evaluation index system of students'achievement,and it is concluded that the first princi⁃pal component has the greatest influence on the final comprehensive score of students,and the ranking obtained by using the principal component analysis method is basically consistent with the traditional achievement evaluation method,but the results of students'scores on each principal component can visually show the students'strengths and weaknesses in the subjects,which can help students to make up for their weaknesses.
