It is an experimental study with a quasi-experimental research design. The research data were obtained from the pretest-posttest scores and the observational results of communication skills. The results showed that the value of the correlation coefficient was r = 0.61 having a contribution of Basic Competency = 37.21%. The results of the data analysis observation sheet on the students' communication skills showed that the value of the correlation coefficient r = 0.81 having the contribution of Basic Competency = 65.61%.
