The teachers giving lectures on such subjects as arts, physical education, mathematics, philosophy, English apart from the professional courses at the Vocational High Schools are defined as the culture teachers. This research was conducted with 102 culture teachers who had taken a drama course in the content of in-service training. Before and after the practical drama course of 30 hours which included the characteristics of creative drama and its use as a method, open-ended questions were asked for content analysis to the teachers and four of the teachers were interviewed six months after the course. It was found out that the culture teachers' awareness of the definition, dimensions, stages, general characteristics and purposes of creative drama increased and most of the teachers desired to make use of creative drama in their classes after the course and in addition to these, the course met the expectations of the majority. Besides these, the teachers made some suggestions about the drama courses like increasing the number of such courses, making it gradual and extending its time. Other suggestions may include the identification of the general framework of the drama courses to be given within the context of in-service training on the basis of the views of experts and teachers, the organization of drama courses to be given by experts through practical processes, conducting more studies about the personal development of the culture teachers, their professional motivation and its relation to the creative drama.
