学生的综合素质受多种因素影响,如何建立科学的评估体系是各大学多年来一直探索的问题。经 过分析各种因素建立了高校学生综合素质 模型,并对高校学生的综合素质进行科学地定性与定量分析,通 AHP 过模型计算表明:综合指数得出的结果能对学生的优点和弱点作出客观评价,有利于学生的全面发展,对当前进 行素质教育具有现实意义。-The overall quality of students affected by many factors, how to establish a scientific evaluation system of universities is to explore the issue has been. After analysis of various factors to establish a comprehensive quality model for college students and college students to carry out the comprehensive quality of qualitative and quantitative scientific analysis, Qualcomm AHP model calculations have shown that: composite index can be the result of the strengths and weaknesses of students to make objective evaluation, is conducive to the holistic development of students, carried out on the current quality of education has a practical significance.
