基于六所部属师范大学数学专业免费师范生现状的调查数据,探讨是否允许考研和学习动力之间的关系.经典累积logistic模型对数据的拟合不佳.利用累积logistic混合模型,很好的拟合了数据,得到如果允许考研将提升免费师范生学习积极性的结论.

英文摘要：

Based on a comprehensive investigative research for all tuition-free normal university students in the Mathematical major,we are to investigate the relationship between the right to take postgraduate education and students＇ learning motivation.Classical cumulative logistic regression model fits data poorly.By using logistic mixed model which fits data well, we find out that students who axe permitted to take the postgraduate education will have stronger learning motivation.
