Abstract: Studied the effects of trait anxiety and state anxiety on creativity of the students，using 138 secondary school students. As the results of the studies abroad were contradictory to each other, the methods of their studies also had poor ecological validity, this paper tried to explore the influence of the students anxiety on their creativity in teaching activities through field experiment of teaching and using the stimuli in real teaching situation to induce state anxiety of the students. The results showed that trait anxiety had no effect on creativity, but the creativity score of low-state anxiety was significantly higher than that of their high-state anxiety counterparts, demonstrated mainly in fluency and flexibility.

Key words: trait anxiety, state anxiety, creativity, ecological validity
