An innovative country is based on innovative talents. How to realize this goal by a basic subject

course? Herein，we propose a Practice -Theory -Innovation ( PTI) teaching model of professional curse. In this

model，students do practices first to experience the applications of theory. Then，they will seek answers from theoretical

study. When they come back to research，they will make innovative achievements. Thus，this model focus on

not only the form and contents of classroom teaching，but also out-of-class research activities. Since 2017，the executing

of PTI model has led to remarkable improvement，resulting in fourteen SCI papers of undegraduate students.

It has been found that the student's innovation capacity can be improved by combining in-class lecturing and outof-

class activities.
