Abstract:       In view of the phenomena of using the same standard comprehensive evaluation to all students in the current university, not considering the difference of individual special ability of the students, and avoiding to produce the phenomenon of high grade and low ability of the students, the rough set theory and the average evaluation method were used to find out the weak link of students' ability and to enhance students' ability of different quantization. The experiments showed that the students' comprehensive ability could be evaluated by the rough set theory, which also provided theoretical basis for the students to improve their comprehensive quality and ability.

摘要：         针对目前高校对所有学生采用相同的标准进行综合评价、不考虑学生个体专项能力的差异、学生高分低能的现象,采用粗糙集理论和平均测评方法找出了学生能力的薄弱环节,并针对性地对不同学生的能力提升进行了量化。实验结果表明,基于粗糙集理论可精确地对学生的综合能力进行评价,同时可为学生有针对性地提升综合素质和能力提供理论依据。
