学生学习成绩相关性的研究

从大学生学习成绩出发,应用广义线性回归模型研究了学生学年间成绩的相关性,揭示了大学一年级,尤其是一年级的二学期是影响学生后期学习的关键阶段.进一步应用聚类分析,得到学生成绩在大学一年级就已经埋下了两极分化的隐患,应用判别分析得出了两极分化的关键课程.该结论为教育教学和学生管理提供决策依据.

Research on the Relativity Between Students' Grade

The paper investigates the relativity between students' grade from the view of students' achievement by the model of generalized linear regression. It is revealed that the first academic year, especially the second term is the pivotal time when the academic record influences the latter study observably. Further, the cluster analysis is applied to find out that the polarization potential has already been laid in the first academic year. And the discriminant analysis is used to discriminate the courses which lead polarization easily. The conclusion is available for instruction and management of students as decision-making basis.
