With an approach to teaching as a performing art, this study investigated the effects of creative drama on eight teaching skills and perceptions of 15 ELT (English Language Teaching) student teachers who took part in a 30-hour creative drama workshop. Their video-recorded teaching in a real classroom atmosphere was observed and evaluated by the researcher and two other trainers before and after the workshop to compare how their teaching skills changed based on the intervention. The results of the content analysis of observers notes on MAXQDA program showed that they improved all target teaching skills, but particularly body language, affective atmosphere, and spontaneous decision-making. Additionally, the content analysis of the reflections they kept after each drama session and the drama products including brief discussions during the sessions revealed positive perceptions on drama in teaching, design of drama sessions and video-recorded teaching. Based on these results, it was suggested that drama courses in ELT programs should be revisited.
