The purpose of this study is to reflect the effectiveness of a drama education program, identify the pro-social behaviour level of children, and determine the effects of the drama education program on the pro-social behaviours of children. In this study, experimental method with the pre-test, post-test retention control group design is adopted. General information form and a Collaboration-Cooperation-Sharing Observation Form are used as data collection tools. Under the scope of this study, a 12-week drama education program is applied. The results of the study show that there is a significant difference between pre-test/post-test and retention scores between the experiment and control group. It is seen that drama education is effective for children to gain collaboration, cooperation and sharing behaviour, to adopt these behaviours and to internalize them.
