Data analysis used Two Ways ANOVA. The sample of this research is class XI TKR 1 & 4. The results of this study are (1) there is a significant difference in the learning outcomes of body electricity between the groups using RRBS and RRK. (2) there is a significant difference in the learning outcomes of body electricity between groups of students who have low, medium and high self confidence.
