The term dramatic pedagogy combines dramatic/theatrical/artistic expression with upbringing/education/pedagogy. CCDE (Croatian Center for Drama Education) plays an important role in promoting drama pedagogy in Croatia through workshops, seminars and education. Drama as such is used in preschool institutions to encourage the positive development of children and to develop their skills and creativity. A drama center or drama game center provides space for exploring roles and situations and developing an understanding of the world of adults. Educators adapt materials to support children's interests and encourage their development through dramatic play. It’s important that educators approach children's dramatic creativity individually, freeing children to express their imagination and creativity. Dramatic expression is a specific way of expression in dramatic art, which includes the pronunciation of words, movement, art, music and their combination. It represents the pinnacle of expressiveness in the development of a child's dramatic creativity and is used as a means of experiential learning and dramatic education. Drama is the essence of dramatic expression and is considered an important skill. Process drama is a form of dramatic art in which participants take on roles to bring an imagined dramatic world to life, with almost the entire group taking on the roles simultaneously. The episodic structure of process drama allows for interruptions in action and in and out of roles, providing participants with flexibility for reflection and change during the drama process. Openness to the participants and responsibility of the leader are key elements of process drama that encourage the engagement of participants, the development of creative and social competences, and the achievement of personal and group development through play and art. In process drama there is no traditional audience, but the focus is on the active participation of the participants instead of a performance for observers. Various dramatic techniques and roles are used during the performance. The aim of this paper was to investigate how dramatic expression develops in children using procedural drama, and the positive outcome of the research was presented in a group of older and preschool children.
