In this study, the teacher support scale, the hardiness scale and the learning adaptation scale were used in a kindergarten teacher's college in Changde. A survey was conducted among 1148 college students to analyze the relationship between teacher support, hardiness and learning adaptation, and to explore whether hardiness plays a role in the moderation between teacher support and learning adaptation. The result is that: (1) Teacher support can significantly predict students' learning adaptation; (2) Hardiness can also be significant predication of students' learning adaptation; (3) Hardiness can play a moderator role in teacher support and learning adaptation. I conclude by acknowledging the limitations of this study and recommending further research.
