It was found that the studies conducted on the creative drama (Q=90,019 p <0,05; I2= 78,893) method showed a heterogeneous distribution, and there was no publication bias. According to the results of the study, the creative drama method had a very large effect size (d = 1,17061) on the success of the social studies course in favour of the experimental groups which utilized the creative drama method. Regarding the effect size results in terms of the years, type and class level of the studies, the effect size of the studies published between 2006-2012 (d=1,208) was higher and was largely positive. Studies published as articles had higher effect size than the theses, and the effect size was perfectly positive. When the effect size of the sample group was examined in terms of the grade levels, it was concluded that the class with the huge effect size was 8th grade (d = 2.733) and the class with the lowest effect size was 4th grade (d = 0.709).
