The purpose of this study was to investigate the effects of online ballet community-based teacher-parent computer-mediated communication (CMC) on four achievement goals of ballet students. We used a randomized post-test only control group design. In order to test whether teacher-parent CMC has a positive impact on the improvement of achievement goals, multivariate analysis of covariance were performed with the ages of ballet students as the covariates. Teacher-parent CMC had significant effects on achievement goals. The mastery-approach goals of the experimental group were significantly higher than of the control group. In contrast, the performance-avoidance goals of the experimental group were significantly lower than those of the control group. There were no differences between the two groups in mastery-avoidance and performance-approach goals. Above all, this study is significant because the focus was placed on the inter-relationship between the two settings of school and family in regard to ballet student improvement, rather than on one setting only.
