摘　　要：本文基于典型调查数据,研究了大学课程的收获度。首先,利用相关系数研究了学生成绩与课程收获度的关系;其次,利用列联表分析了教师授课水平与课程收获度的关系;最后,建立课程收获度截断模型,研究了课程收获度的影响因素以及影响程度。模型回归效果良好,可以用于课程收获度的评价和预测。This paper studies degree of gain about collegial curricula.Firstly,we analyze the relationship between grade and degree of gain by correlation coefficient.Secondly,we analyze the relationship between lecturer＇s level and degree of gain by contingency table.Finally,we set up truncated model in order to study influencing factor and degree about degree of gain from collegial curricula.The model has good regression effect.Therefore,this model can be used to evaluate and forecast degree of gain about collegial curricula.
