The aim of this study was to investigate: a. the effect of an interdisciplinary program of Greek traditional dance by the means of the teamwork method of teaching social skills to students. b. whether this effect was similar for boys and girls. The sample of the study constituted of 206 elementary school pupils (4th, 5th, and 6th class). The intervention program lasted for two months. There were a total of sixteen lessons (2 per week) which concerned the acquisition of social skills through Greek traditional dance (the experimental group). The method in use was either the group divided work or teamwork. The Greek version (Masadis et al., 2016) of Matson Evaluation of Social Skills with Youngsters (MESSY-II) (Matson et al., 2012) was applied to collect the research data. This in order to be analysed required the following statistical analysis: a. Descriptive statistics b. t-test for independent sample c. Reliability analysis (Cronbach's a) and d. Repeated Measures ANOVA. The findings and the evaluation of the study suggest that the teamwork method is the most appropriate to adopt in social skills learning for the last 3 grades of primary school and traditional dancing the best choice to make.
